1. Foreword Designing, fabricating, and deploying a ship or offshore structure is a capitally intensive and time-critical exercise. Top design, engineering, construction, and operating companies are now looking to new and innovative capital project life cycle management (cPLM) technologies and methodologies to deliver competitive advantage where “time to market,” “time in market,” and “optimized operations” are key performance metrics. However, cPLM should not be confused with traditional product life cycle management (PLM), which has been used to great benefit in the discrete (aerospace, automotive, electronics, and consumer goods) manufacturing industries for many years. cPLM is more expansive than PLM for “engineer to order” manufacturing strategies. So, what is cPLM, and how is it different from PLM? This white paper – written and prepared by Intergraph– will explore the technical and business differentiators between cPLM and PLM. The inherent differences between the two technologies as they apply to the shipbuilding, marine, and offshore development industries will be explored.

Conclusion .............................................................................................................................. 19 cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page i 2. cPLM vs. PLM (Capital Project vs. Product) There are two fundamental components of a cPLM or PLM strategy nicely summarized by Michael Grieves, author of Product Lifecycle Management: Driving the Next Generation of Lean Thinking (McGraw-Hill, 2006). He writes: “Product Lifecycle Management (PLM) is an integrated, information-driven approach comprised of people, processes/practices, and technology, to all aspects of a product's life, from its design through manufacture, deployment and maintenance – culminating in the product's removal from service and final disposal. By trading product information for wasted time, energy, and material across the entire organization and into the supply chain, PLM drives the next generation of lean thinking.” If we quickly differentiate between these two approaches, it would be the following: PLM – The design process executes and derives every bill of materials (BOM) for the product BEFORE any production and procurement begins. The design BOM is divided into manufacturing BOM groups for production plan. Production commences on many identical products or pre-determined variations of the BOM. cPLM – Design and procurement begin at the same time. The manufacturing BOM evolves from initial BOM. Procurement BOM changes DURING design evolution. As such, it is clear the processes, practices, and technology for these two approaches are fundamentally different. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 1 3. Capital Project and Product Manufacturing Differences The key difference between companies operating in either of these spaces can be summarized between these phrases – “engineer to order” and “engineer to stock.” Engineer-to-order companies are typically project-driven, whereas engineer-to-stock companies typically produce product without a specific customer in mind. The table below highlights these differences: Engineer-To-Order (ETO) Capital Projects Engineer-To-Stock (ETS) Discrete Manufacturing Few products Thousands of products Few customers Many customers Finite production capacity Variable production capacity Few configurations Thousands of configurations High cost/capital intensive (product & mfg) Global variance (design/build anywhere) Millions of objects and relationships Thousands of objects and relationships Specify and order before design completion Optimize sales and supply chain post design Build as the product is designed Preparation for mass manufacture of the product Evolutional, dynamic, and variable BOMs Manufacture against finalized BOMs Heavy regulation, safety, hazardous materials Automation of production line Product in service life >20 years Product in service life <10 years Clearly, the processes/practices on either side of this “product-definition” spectrum will be different: On the left-hand side – the capital project – the product is typically the plant, ship, or facility delivering the product On the right-hand side – discrete manufacturing – the product is the product or service ultimately delivered to the end-user by the former cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 2 3.1 Few Products A shipyard essentially sells its production expertise for delivering to the customer a marine structure on time, on budget, and within its operational parameters. A yard may even specialize in one form of product, such as ships of the same size, range, or type (European yards specializing in cruise ships; Japanese yards in bulk carriers; Korean yards in LNG/FPSO/containers, etc.). In other words, a shipbuilding company doesn’t speculatively “build to stock” products it might sell on the open market; rather, each order is a project, a capital project. In contrast, a car manufacturer designs, assembles, and sells many different products – a range of cars with multiple options and variations “engineered and built to stock” for the open market. Therefore, cPLM is focused on project execution – meeting the delivery deadline – as opposed to PLM, which is focused at meeting a market window of opportunity. 3.2 Finite Production Capacity Throughput of the shipyard – the ability to fabricate, commission, and float out the product – is critical to commercial success. Consequently, shipbuilding is a concurrent engineering and manufacturing task. Just-in-time design, just-in-time fabrication, having materials and resources on hand for both, and optimizing the production of the laydown yards and dry docks all mean that cPLM is for concurrent and multiple project execution against a finite capacity plan. This is in contrast to a discrete manufacturer who, based on market demands, could build a production facility at another location, or reduce the assembly workstation to bolster lead time. 3.3 Few Configurations “Experienced design” in shipbuilding is a process of deriving a new ship from previously existing executed projects. Essentially, it is the process of harvesting and harnessing the knowledge from previously successful projects to rapidly respond and deliver to the customer. These derived configurations are more concerned with reuse and re-purposing than they are about managing multiple variants, options, and alternatives. cPLM is focused on derivative management. PLM, however, focuses on variants, options, and alternatives for different markets and customers. 3.4 High Cost, Capital Intensive (Product and Manufacturing) As indicated in Section 3.2 Finite Production Capacity, new production facilities are not a viable option. It is critical to optimize and streamline the available resources, production schedule, and material availability. Any days shaved off production not only yield extra capacity availability for the shipyard, but also extra production capacity for the customer (and reduce interest payments on the capital invested). Therefore, cPLM’s focus is on cost management and progress against schedule rather than sheer production capacity and volume delivery, which is the focus of PLM. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 3 3.5 Millions of Objects and Relationships Data volumes in shipbuilding are huge. An FPSO, for example, may run into millions of objects and relationships which have numerous iterations. Sharing the correct information between multiple disciplines in a concurrent engineering environment is vital. As a result, cPLM views accuracy, validity, integrity, quality, timeliness, change impact, and change management as critical success factors. 3.6 Specify and Order Before Design Completion Many items on a ship or marine structure are not available “off-the-shelf” and need to be ordered as early as possible before the design is complete to ensure their availability as required during fabrication. For that reason, the BOM not only needs to distinguish between what is and isn’t ordered, but also needs to synchronize the delivery to the yard as required. Of course, once ordered, the change management capabilities of the cPLM need to prevent or escalate changes that would affect these ordered items. The cPLM focus is on just-in-time fabrication versus planned, just-in-time manufacturing for PLM. 3.7 Build as the Product is Designed The limiting factor of the ability to deliver more ships is the finite production capacity of the yard. Therefore, design and fabrication must execute simultaneously. The yard cannot wait for the design to be complete, nor can it wait for materials and package units to all be available when fabrication commences. The cPLM needs to facilitate inter-discipline communication and collaboration and be proactive with change impacts to and from design, procurement, and fabrication. Its focus is on agility, not planned predictability. 3.8 Evolutional, Dynamic, and Variable BOMs As the design is progressing and changing, so, too, will the BOM. It will be evolutional, dynamic, and variable. Material rollups and shipping reports stores/warehouse usage will be different day by day. This is completely opposite from discrete manufacturing where the BOM must be known and finalized prior to manufacture. Additionally, tracking which material has been consumed on which vessel in fabrication for cost management reporting ensures schedule and cost management. The cPLM focus is on evolutional, dynamic, and variable BOMs, not fixed and final BOMs. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 4 3.9 Heavy Regulation, Safety, and Hazardous Materials Ships and marine structures must operate within a strict regulatory framework, as well as in a safe manner, often while transporting hazardous materials. Having this safety structure integrated during intelligent design is an obvious advantage. cPLM must support experienced design, as indicated earlier, and also collaborate with regulatory and classification societies. The automation and established rules need to guide and monitor the design and fabrication process. In cPLM, rules and automation are imperative, rather than unconstrained innovation as found in PLM. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 5 4. Technology Differentiation If the processes to develop the “product” on both sides of this design and manufacturing spectrum are different, the cPLM and PLM technologies are different as well. However, what is often confusing is that the terminology looks identical at a high level. For instance, any PLM software vendor or document on the subject will refer to the following requirements for a PLM system: Product data management Document management Configuration management Engineering change management Product and process definition Collaboration applications Visualization/viewing/reviewing Data exchange and data integration Program management Interfaces for heterogeneous CAD Others – regulatory compliance, warranty/service, spares/consumables/replacements, catalog management, requirements management/tracking, MRO What is not immediately obvious with the above list is the technology required to deliver these functions. It differs for cPLM and PLM. This is as much because of the heritage of the software vendors as it is about the functional requirements. cPLM (Capital Project) PLM (Discrete Manufacturing) Data-centric File/part-centric Data sharing Data exchange Managed inconsistency Enforced consistency Topological networks Hierarchical assemblies Integrated disciplines Digital mock-up Configuration management for derivatives Configuration management for variants 4.1 Data-centric vs. File/Part-centric Traditional CAD/CAM systems evolved from a paradigm in which the software application would read/write to a file. In mechanical CAD systems, this invariably meant a file represented a part, and visualization or digital mock-up software manipulated how the parts were assembled together. This methodology is still appropriate in discrete manufacturing companies where the parts can be isolated, and various tools – such as CADD, FEM/FEA, and CNC – can all work on the same file format. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 6 CAD for the process, power, and marine industries originated from the same roots, but exposed some fundamental limitations of the approach. A single file could not support the size of a whole ship, nor could it accept writes from multiple users. Consequently, the ship would be divided into many files, where each file may represent a ship’s block, as illustrated below. However, systems such as a piping, instrumentation, electrical, etc. would need to span across these files. The simplest solution for most software vendors was to leave the CAD engine largely intact, but develop software (PDM) for their tools to communicate between the files via a database application. This software would manage the interfaces, whether they be logical (e.g., from/to) or physical (e.g., coordinates) connections between the files. This approach applies equally to schematic (for example, to accommodate “off-page connectors”) and 3D software applications, and works fine up to a point. However, as shipbuilders started to optimize their vessel designs into configurable blocks to support modularity and experienced design, the integrity of the network systems (piping, electrical, instrumentation) was put at risk as each discipline modified their data within each file. The development of digital mock-up (DMU) software partially addressed this problem, essentially putting the whole model back together again to ensure the connectivity/integrity of the interfaces between each file. But the software would also need to interrogate and extract specific data from each file to establish “line list,” “bill of quantity,” “center of gravity,” etc. So the question now is, “Is the source of the truth now in the files or in the database?” cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 7 Different CAD software with distinctive file formats would exacerbate this assembly, interoperability and data access problem. This, in turn, leads to initiatives to standardize the file formats (e.g., JTOpen or STeP [ISO10303]) for this data exchange to occur. Obviously, there is a case to be made that much of the value in the engineering process was in the data, not the file. The solution was the design engineering tools should interact with a database, not a series of files that exacerbated the exchange problem. Intergraph’s SmartMarine® Enterprise suite of tools is data-centric. It is a rule-driven solution for streamlining design processes while preserving existing data and making it more usable and reusable. A user interacts with the application that reads/writes to a multi-user, multi-discipline database, not with a CAD system that reads/writes to files on the file system. Drawings and document deliverables are reports derived from the database. 4.2 Data Sharing vs. Data Exchange One of the inherent benefits of a database approach versus a file-based approach is the apparent immediacy of data being available to all applications and users almost instantaneously. We can think of it as this simple analogy: In a database, data is free-flowing and available to multiple sources. Everyone in the database is surrounded by and soaked with data. It is free-flowing and constantly changing. In a file-based system, data is locked inside, much like a castle. Access to the data requires a key to the fortress. What goes on inside the fortress is invisible to those outside. What is the fundamental difference between the terms “sharing” and “exchange” in the context of the above and the engineering process? The following simple example helps illustrate this concept. Imagine there are two different disciplines (process engineering and mechanical engineering) using two different applications as part of the design process – a 2D schematic P&ID application and a 3D physical modeling application. At the start of the project, the process engineer places a pump symbol in a P&ID system and names it P-101. While the 2D schematic is being refined, the 3D designer needs to start work and requires preliminary design information from the process cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 8 engineer, and so places P-101 in the 3D model. Later on in the project, the process engineer determines that the pump P-101 needs a hot-standby pump and renames P-101 to P-101A and adds P-101B. This may be a simple change. But what could this look like with respect to systems sharing versus exchanging data? A methodology setup for exchange would take a scope of data from the primary application (P&ID) and extract it into an exchange file of some predetermined format (potentially with data mapping and transformation). It may be stored somewhere – perhaps on the file system or a PDM/PLM system. Subsequently, a user would load the data into the second application (3D). But what would be loaded? In the first exchange, the “exchange file” would incorporate the details of pump P-101. In the second exchange, pump P-101A and P-101B would be included. How would the second application determine there were not now three pumps – P-101, P-101A, and P-101B – but instead, P-101 had not been deleted, but had simply been renamed to P-101A? See the following illustration. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 9 Sharing, therefore, requires that a deeper level of information is made available on both sides of the application divide. This information needs to encompass changes, renames, updates, and deletes, otherwise known as CRUD. Additionally, both applications need to act on them accordingly. See the following illustration. SmartMarine Enterprise employs a system of data sharing through a common, applicationneutral data warehouse. This methodology supports the sharing of data from any third-party application using standardized interfaces, which dramatically reduces the need for fragile point-to-point interfaces. Each application provides a common interface to share and accept data through a negotiated transaction. This is presented as a “to-do list” in which the user may choose to accept or reject the information arriving from other applications. It ensures the engineer is in control of his or her own data at all times. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 10 4.3 Managed Inconsistency vs. Enforced Consistency Engineering is not a volatile, real-time process. Nor is it one in which consistency across different disciplines can be rigidly enforced. If the facts were changing in real time, no decisions could ever be made or relied upon. Consider this example: A piping engineer has to place a hanger for a pipe system onto some supporting steelwork. If the structural engineer were changing/moving the structural member at the same time and the piping engineer were seeing this, he or she would never be able to complete his or her work. As a result, the piping engineer needs to work with the latest released data, while the structural engineer moves on with his or her design, but both need to be notified as appropriate when the object of interest is in the process of being changed. If data consistency between disciplines were rigidly enforced, it would be like making decisions on shifting sand. Consider another example: Referring back to the “pump P-101” example mentioned earlier, we’ll return to the scenario halfway through where the process engineer had created P-101A and P-101B in the P&ID that was made available to all other applications in “real time.” The 3D designer subsequently decided to delete P-101B from their model and make P-101A a different capacity. What would happen to the process engineer’s data in the P&ID? Would it simply be removed or changed? Imagine coming to work one morning to find all the information you had created the previous day had been changed. Trust in the information would soon be lost. Imagine how such a system would quickly fall into disuse. Engineering is an iterative, negotiated process where decisions are made at certain points in time against best available and qualified facts. Those facts will change throughout the life cycle. Change is inevitable and the substance of an evolving design. Changes will not all happen in harmony at the same (real) time. At any point in time, the data across the enterprise between disciplines will actually be inconsistent. This is not inherently a bad thing. It is the normal state of an engineering project. Engineers from different disciplines iteratively work on their own data, share data with others, and drive out the inconsistencies through a process of sharing transactions. It does mean, however, that these inconsistencies will need to be managed to avoid costly errors. This milestone management is the traditional version/revision/issue/release process that engineering disciplines working in a concurrent engineering environment accept as best practice. In other words, the data for each discipline requires segregating until it is released or made available to another discipline. The process by which data is made available may vary from system to system. In a traditional PLM (file-based) system, this release process usually involves either changing access permissions on the file to allow other disciplines to check-in/out the file, or providing digital mock-up (DMU) software to create an aggregate view of the different discipline files. Nonetheless, as discussed previously, this file-based approach does not lend itself to real “sharing” and reuse of the data. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 11 For a data-centric cPLM, an alternate methodology to check-in/out and DMU is required. Some have argued for a unified “mother-of-all-databases” (MOAD) where data is concurrently shared between multiple disciplines to enforce consistency. But this approach fails for the segregation reasons indicated above. Class-leading cPLM systems, such as SmartMarine Enterprise, utilize a paradigm of publish/ retrieve between segregated data domains to achieve data sharing between disciplines. This practice of “publish/retrieve” is a fundamental component of a cPLM system. One discipline publishes its data when it reaches a certain stage (when ready to share it with other disciplines) and notifies interested parties in other disciplines that new information is now available for them. When those disciplines are ready – either before or after their own publish milestone – they may choose to retrieve that data into their application. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 12 Therefore, each discipline’s published data is kept application/discipline-specific. There will be no possibility for engineers to overwrite data that does not belong to their application or discipline. Naturally, there will be the possibility for common data to be inconsistent between applications. Intergraph’s SmartMarine Enterprise manages this capability by publishing/retrieving between the tools via SmartPlant® Foundation (SPF) and its multiple data domain design. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 13 The cPLM system must, therefore, monitor, report on, and allow this data to be made consistent during the life of the project. The following screenshot illustrates inconsistent data regarding a single instrument published by a number of applications residing in SmartPlant Foundation. The first column shows the data last published. The other columns represent the same data as published by other applications. Where the data is inconsistent between published domains, it is highlighted for the relevant discipline to correct – it is the equivalent of the traditional engineers’ “yellowlining” squad check. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 14 4.4 Topological Networks vs. Hierarchical Assemblies PLM in discrete manufacturing evolved from PDM technologies. These systems, as indicated previously, were designed to manage the various files created by CAD/CAM/FEA tools. Not only did they manage the metadata (e.g., title, author, revision, etc.) of the file, but they also managed the relationships between these files to represent various hierarchies – such as assembly, bill-ofquantity, as-designed, as-manufactured, etc. Manipulation of the views, such as filtering out relationships of a specific name, allowed users to manipulate the various structures. By extracting the properties from the file (as indicated earlier), the user could develop a view specific to a business purpose (e.g., BOM). cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 15 However, the accuracy of this BOM is limited due to a number of factors, including, but not limited to, the frequency of exchange/extraction of the data from the source files and the frequently changing lengths of the network segments (see Section 4.1 Data-centric vs. File/Part-centric). Piping, instrumentation, electrical, and HVAC are not easily managed in such flat, hierarchical views since they are networks. They are topological, often with multiple start and end points. Conceptually, they are more like a molecular matrix than a flat hierarchy. This image is of a molecular matrix representing a topological system, where the spheres represent nodes or objects. This image shows a flat hierarchy representing an assembly where the spheres represent nodes or objects. Why is managing such a topological network in a data-centric environment important? 4.4.1 Find What You Need by What You Know In a hierarchical system, the structure and its nomenclature are defined in such a way that everyone who knows it can find what they need. But it means that navigation is not always intuitive, and it is impossible for casual users who do not understand the structure. In a molecular network, the nodes and objects represent things of interest to multiple disciplines during the project life cycle (e.g., blocks, systems, areas, equipment, documents, drawings, suppliers, purchase requisitions, process plans, etc.). Users can start at any point on the network about something they do know and navigate to where they need to be. By integrating this “query by relationship” with more traditional “query by example” (metadata search) and “query by content” (full text-retrieval search), a cPLM system accommodates all classes of user – from the “information professional” to the “casual user.” 4.4.2 Evolving BOM One thing is certain about a marine or offshore structure. Until it is finally complete and deployed, its BOM will constantly evolve as design and fabrication occur simultaneously. Visualize a simple case in a piping system where during design, a reducer in a pipeline is moved from one block to another. This would materially change the pipe length requirements for the different diameter pipes. As the BOM process involves rollup for multiple piping systems throughout the ship, this recalculation of the BOM would become an arduous task in the file/part-based hierarchical approach. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 16 4.4.3 Change, Impact, Analysis, and Management In a network, a small, seemingly insignificant change can have major material impact. Changing a pressure or temperature in a process flow sheet can change bore size of a piping network and installed mechanical equipment such as valves, pumps, instruments, the BOM, weight, center of gravity, and so on. Assessing the impact of these potential changes before they are approved is made substantially easier by having the ability to traverse and analyze a connected network of related objects. Isolating the changes in data domains and managing the inconsistencies ensure there are no surprises as the fabrication evolves. But a ship or marine structure is not wholly a topological network. Hull forms, mechanical equipment, and structural members are also representative of traditional assemblies. Therefore, the cPLM system needs to manage a hybrid of topological networks and hierarchical assemblies. SmartMarine Enterprise is designed to support both of these, integrated together, and present them to users in a uniform way to optimize learning and familiarization. 4.5 Integrated Disciplines vs. Digital Mock-up File/part-centric design systems rely on DMU technologies to assemble and view the entire, multidiscipline product from the multiple constituent parts (files) in the PLM system. These DMU systems either utilize a single common format (proprietary systems such as JTOpen or industry standards such as ISO10303 STeP) for the file or have the ability to open multiple formats from multiple vendors. The DMU software analyzes the location/coordinates/scale and assembly connectivity to present the user with a real-life view. However, as indicated in the previous discussion, any interrogation of the data for these parts is entirely dependent on the rendering capability of the source system and the data scope of the receiving file format (with, of course, any mapping/transformation in the middle). Tasks such as interference detection, 2D/3D analysis, measurement, cross-sectioning, and comparison in a file/part-centric system are all after-the-fact exercises, whereas in a data-centric, multi-discipline database, these functions are available as an integral part of the design process. The Smart 3D technology of the SmartMarine Enterprise is a multi-discipline, data-centric design system which enables all these tasks without the need for a post-design DMU application. It is a live, active DMU that does not require reassembly or post-processing of the separate files. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 17 4.6 Configuration Management for Derivatives vs. Variants As indicated in Section 3.3, experienced design in cPLM is about deriving new configurations by reusing or re-purposing existing designs. In some cases, this means defining a “mother ship” as a template and deriving dissimilar “sister ships” from this baseline, such as removing blocks, adding different equipment/outfitting, or altering specific parameters. In other cases, it may mean deriving a ship using a mix-and-match approach from a fleet of designs. However, in either case, the resulting ship will be a unique configuration in its own right. This derivative approach is different to the variant approach in PLM for discrete manufacturing, where the designer attempts to satisfy many different customer and market needs from a palette of options. In this case, each option or alternative is part of the same basic structure. The different variations of the product can be viewed by manipulating the option/alternate relationships between the objects in the PLM system. SmartMarine Enterprise supports configuration management of derivates where the hull applicability is managed in the tools. Design changes are fed between the tools and each configuration is separate and unique. Yet, there is the ability to query across multiple configurations. This is necessary to understand the baseline from which a new derivative is to be established and to determine the unique differences. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 18 5. Conclusion Intergraph’s SmartMarine Enterprise is a next-generation cPLM designed solely for shipbuilding, marine, and offshore structures. It is not a re-purposed, discrete manufacturing CAD/CAM/PLM solution like those currently available on the market – Siemens/Teamcenter, Dassault Systemes/ ENOVIA, AVEVA/OpenPLM (recently renamed AVEVA NET), PTC/Windchill, and others. Intergraph is the only vendor to offer a cPLM system based on the concepts described in this white paper, which better fit the shipbuilding and marine industries. SmartMarine Enterprise is totally data-centric, where the deliverables are reports and renderings of the database. It is open by design and provides cPLM characteristics: Data sharing Managed inconsistency Topological networks Integrated disciplines Configuration management for derivatives Its unique Smart3D technology, used for the physical configuration of the marine facility, is multi-discipline and performed against a single database with no limitations in terms of numbers of objects or numbers of concurrent users (see Section 4.1 Data-centric vs. File/Part-centric). It provides rule-based automation (based on a patented “associativity” methodology) that is able to boost the design-to-production process by capturing and utilizing industry standards and companyspecific know-how. Global workshare further opens Smart3D to accommodate remote and partner collaborative ship development. SmartMarine Enterprise integration, such as between functional (2D) and topological (3D) applications (e.g., schematic P&ID with 3D outfitting arrangement), manages and promotes consistency during design, not the “check afterwards” approach required by non-integrated systems. Similarly, application and data integration with major applications, such as nesting, enterprise resource planning, and scheduling, position SmartMarine Enterprise as the nextgeneration cPLM for shipbuilding, marine, and offshore industries. cPLM vs. PLM for the Shipbuilding, Marine, and Offshore Industries Page 19 For more information about Intergraph, visit our Web site at www.intergraph.com.
