CHANGES
MOTIVES
This Service Specification was approved by the Director of Technology in July 2006.
New technology is generally not adequately covered by established codes and procedures. New technology
must therefore be qualified by a systematic process where the required functionality and reliability is obtained
by identifying uncertainties which needs to be reduced through adequate qualification methods such as testing
and analyses. A guideline for such a systematic qualification process is given by DNV-RP-A203 Qualification
Procedures for New Technology.
While DNV-RP-A203 provides a general process applicable to the technology owner and his affiliates, DNVOSS-401 describes DNV’s services based on that process. The objectives of introducing the document are to
contribute to uniform service deliveries across the organisation and to serve as a reference document for
defining the scope of work in accordance with the customer’s expectations.
General
As of October 2010 all DNV service documents are primarily published electronically.
In order to ensure a practical transition from the “print” scheme to the “electronic” scheme, all documents
having incorporated amendments and corrections more recent than the date of the latest printed issue, have been
given the date October 2010.

SECTION 1
GENERAL
A. General
A 100 Introduction
101 This new Offshore Service Specification (OSS) gives guidance on Technology Qualification
Management as a service provided by DNV.
A 200 Objectives
201 The objectives of this document are to:
— describe DNV’s Technology Qualification Management services for offshore structures and systems
— provide guidance for technology owners and other parties for selecting and determining the extent of
involvement of those carrying out the technology qualification activities
— provide a common communication platform for describing the extent of technology qualification activities.
A 300 Scope of application
301 This Offshore Service Specification (OSS) applies to qualification of technology for offshore structures
and systems, particularly addressing qualification of new technology with reference to DNV-RP-A203.
302 This OSS applies to technology qualification within general technology development projects as well as
qualification of new technology related to offshore field development projects.
303 This OSS describes the necessary activities to be carried out to obtain DNV statements of feasibility,
statement of endorsement and certificate of fitness for service.
A 400 Structure of this document
This document consist of three sections and three appendices:
— Section 1 - gives the general scope of the document, background information, definitions and references.
— Section 2 - gives an overview of DNV’s general technology qualification process which is further detailed
in DNV-RP-A203.
— Section 3 - describes DNV’s services related to DNV-RP-A203; describes the deliverables from these
services and provides guidance for selection of the scope of work.
— Appendix A - provides examples of DNV qualification statements.
— Appendix B - provides a table that can be used as a basis for contractual specification of scope of work.
— Appendix C - provides a project start-up check list to support the DNV project management in establishing
good communication lines with the client.
B. Background
B 100 Introduction
101 Technology qualification is in this document defined as: “the process of providing the evidence that the
technology will function reliably within specified operational limits with an acceptable level of confidence”.
DNV’s technology qualification services thus differ from DNV’s third party services (as classification,
certification and verification), which are to confirm that the technology is documented in compliance with
specified codes and procedures.
102 New technology is generally not adequately covered by established codes and procedures. New technology
must therefore be qualified by following a systematic process where the required functionality and reliability is
obtained by identifying uncertainties, which need to be reduced through adequate qualification methods, such as
testing and analyses. A guideline for such a systematic qualification process is given by DNV-RP-A203.
103 While DNV-RP-A203 provides a general process applicable to the technology owner and his affiliates,
this document describes DNV’s services based on that process. These services are here divided into three
groups:
— Technology qualification management.
— Fitness for service verification.
— Qualification executions.
104 Technology qualification according to this document, and the work process as described in DNV-RPA203 may constitute a necessary part of product certification, (see guidance note) when the technology or parts
thereof is unproven and/or not adequately covered by established codes and procedures.

Sec.1 – Page 7
Guidance note:
Product certification is used above as a general term to denote independent verification of a final product versus
established codes and procedure, which is affirmed either by a type approval certificate or by a project specific
statement or certificate. When the technology (or part thereof) is unproven, and hence not fully covered by established
codes and procedures, then the basis for product certification may be complemented by technology qualification of
the unproven parts.

C. Definitions
C 100 General
101 The definitions in DNV-RP-A203 also apply to this document.
C 200 Verbal forms
201 The terms will, can and may are used when describing DNV’s actions or activities, and the terms shall,
should and may are used when referring to other parties than DNV.
202 “Shall”: Indicates requirements strictly to be followed in order to conform to this OSS and from which
no deviation is permitted.
203 “Should”: Indicates that among several possibilities, one is recommended as particularly suitable,
without mentioning or excluding others, or that a certain course of action is preferred but not necessarily
required. Other possibilities may be applied subject to agreement.
204 “Will”: Indicates a mandatory action or activity to be undertaken by DNV. (Ref. “shall” for other
parties.)
205 “Can”: Indicates an action or activity that DNV will not necessarily do unless specifically requested by
the client. (Ref. “should” for other parties.)
206 “May”: Verbal form used to indicate a course of action permissible within the limits of the OSS.
C 300 Definitions
301 Client: DNV’s contractual partner. It may be the purchaser, the owner or the contractor.
302 Conceptually feasible: A technology at an early stage of development is considered conceptually feasible
if the main challenges have been identified and judged to be resolvable by use of sound engineering practice.
Guidance note:
Although a technology has been stated conceptually feasible, there are still activities necessary to be executed in order
prove that the technology is fit for service. Consequently, there will be a possibility that the technology contrary to
expectations will not be stated fit for service.
---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---
303 Fit for service: A technology is considered fit for service when the failure modes that have been
identified through the systematic process outlined in this OSS have been properly addressed, and the supporting
evidence substantiates that the technology fulfils all stated functional requirements and meets the stated
reliability target.
Guidance note:
Although a technology has been stated fit for service, the technology has not necessarily an in-service record that
eliminates the possibility for failures due to unidentified or misjudged failure modes. Consequently, there will be a
possibility that the technology contrary to expectations will fail in-service.
---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---
304 Hazard: A deviation (departure from the design and operating intention) that could cause damage, injury
or other form of loss (Chemical Industries Association HAZOP Guide).
305 HAZID (HAZard IDentification): A structured review technique with the purpose of identifying all
significant hazards associated with the particular activity or operation under consideration.
306 New technology: Technology that is not proven. This implies that the application of proven technology
in a new environment or an unproven technology in a known environment, are both new technology. The
degree of new technology will be classified in categories to be used as input to risk assessment.
307 Probability of success: The probability of completing a qualification activity or a set of qualification
activities within available time and with a successful result.
308 Proven technology: In the field, proven technology has a documented track record for a defined
environment. Such documentation shall provide confidence in the technology from practical operations, with
respect to the ability of the technology to meet the specified requirements.

309 Risk: The qualitative or quantitative likelihood of an accident or unplanned event occurring, considered
in conjunction with the potential consequences of such a failure. In quantitative terms, risk is the quantified
probability of a defined failure mode times its quantified consequence.
310 Risk reduction measures: Those measures taken to reduce the risks to the operation of the technology
and to the health and safety of personnel associated with it or in its vicinity by:
— reduction in the probability of failure
— mitigation of the consequences of failure.
311 Statement of endorsement: A document issued by DNV affirming that, at the time of assessment, it has
been found that the new technology can be proven fit for service through the remaining planned qualification
activities.
312 Statement of feasibility: A document issued by DNV affirming that, at the time of assessment, the new
technology is considered conceptually feasible and suited for further development and qualification according
to the principles outlined in DNV-RP-A203.
313 Certificate of fitness for service: A document issued by DNV affirming that, at the time of assessment,
the new technology is considered fit for service.
314 Technology qualification: A confirmation by examination and provision of evidence that the new
technology meets the specified requirements for the intended use. Hence, qualification is a documented set of
activities to prove that the technology is fit for service.
315 Verification: An examination to confirm that an activity, a product or a service is in accordance with
specified requirements.

SECTION 2
PRINCIPLES OF TECHNOLOGY QUALIFICATION
A. General
A 100 Objective
101 The objective of this section is to give a brief overview of the principles of DNV’s Technology
Qualification work process for new technology as a background for understanding DNV’s qualification
management services as described in Sec.3.
102 A thorough guidance regarding the application of the work process is given in DNV-RP-A203.
B. The Qualification Process
B 100 General
101 Qualification of new technology is a systematic process consisting of various steps:
—
—
—
—
—
—
—
—
definition of qualification basis
technology assessment
failure mode identification and risk ranking
concept improvement
selection of qualification methods
evaluation of the probability of success (PoS)
data collection (analysis and testing)
functionality assessment.
For further guidance refer to DNV-RP-A203.
B 200 Definition of qualification basis
201 The purpose of the qualification basis is, in the absence of relevant codes and procedures, to define the
expectations of the technology. Through further qualification processes these expectations shall be proven to
be fulfilled.
202 The qualification basis should include the following key elements:
— description of the technology to be qualified including system boundaries and operational limitations
— functional requirements
— reliability targets related to safety as well as functional performance.
B 300 Technology assessment
301 The purpose of the technology assessment is to divide the technology into manageable elements in order
to assess those elements that involve aspects of new technology and identify the key challenges and
uncertainties.
302 The technology assessment shall include the following issues:
— division of the technology into manageable elements (see 303)
— assessment of the technology elements with respect to newness (see 304)
— identification of the main challenges and uncertainties related to the new technology aspects (see 305).
303 The technology division shall be achieved by dividing the technology into one or more of the following
types of elements, as relevant:
— sub-systems and components with functions
— process sequences or operations
— project execution phases based on procedures for manufacturing, installation and operation.
304 The degree of novelty of the technology shall be determined by classifying the technology elements with
respect to application area and technology maturity. Elements classified as new technology shall be subject to
the further assessment.
305 The main challenges and uncertainties related to the new technology aspects shall be identified. For
complex systems it is recommended that the main challenges and uncertainties are identified by carrying out a
high level HAZID (HAZard IDentification).

Guidance note:
A high level HAZID is a means of obtaining a better understanding of a system at an early stage, and to identify which
parts of the system that need to be further developed and/or documented in more detail, prior to the failure mode
identification and risk ranking.
---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---
B 400 Failure mode identification and risk ranking
401 The objective of this step is to identify all relevant failure modes of concern for the elements defined as
new technology in the technology assessment and, for each, judge the associated risks.
402 Prior to the identification of failure modes various classes of probability and classes reflecting the
consequence severity shall be qualitatively defined. Based on these definitions a risk matrix shall be defined
showing fully acceptable combinations (“low risk”) and unacceptable combinations (“high risk”) as well as
intermediate combinations (“medium risk”) of probability and consequence classes.
403 All relevant failure modes shall be assigned a probability class and consequence class based on
documented reliability or expert judgements. In the latter case uncertainties shall be reflected by selecting
conservative classes.
404 For relatively complex systems the failure mode identification and risk ranking process is recommended
to be carried out as workshops, involving a panel of experts covering the necessary fields of competences and
experiences.
B 500 Concept improvement
501 The objective of the concept improvement step is to implement improvements that have been found
necessary or beneficial during the failure mode identification and risk ranking.
502 Improvements would normally imply that the previous steps in the qualification process need to be
updated.
B 600 Selection of qualification methods
601 The objective of this step is to select qualification methods that adequately address the identified failure
modes of concern with respect to reduction of uncertainties and documentation of sufficient margins of failure.
602 The qualification methods will, in most cases, include technical analyses, testing or combinations of the
two where the purpose of the testing is to reduce uncertainty in the analysis model or calibrate it. They may
also involve collection of available reliability data and making procedural precautions to avoid the associated
problem.
603 The selected qualification methods will be input to a technology qualification plan (TQP) where the
various issues will be outlined as qualification activities needed to be executed.
B 700 Evaluation of the probability of success
701 The objective of this step is to give a good indication of the probability of completing the remaining
qualification program successfully. This is intended to give a basis for the decision to proceed with the analysis
and testing phase.
702 The evaluation will normally be a judgement of the likelihood of each individual activity in the
qualification plan to give a successful outcome taking the technical challenges and available time into
consideration. When given as a quantitative estimate, this is referred to as the probability of success (PoS). An
overall PoS for all activities may also be made, and economical considerations may be included when agreed
with the client.
B 800 Data collection (analyses and testing)
801 The objective of the data collection phase is to carry out all the qualification activities prescribed in the
TQP.
802 If a reliability target is stated in the qualification basis, then an adequate reliability analysis shall be
carried out taking the new information from the data collection into account.
B 900 Functionality assessment
901 The objective of this phase is to confirm that the functional requirements and target reliability as stated
in the qualification basis are met.
902 This shall be done by confirming that the qualification activities have been carried out, and that the
acceptance criteria for the analyses and testing have been met.

SECTION 3
SERVICE OVERVIEW
A. General
A 100 Objectives
101 The objectives of this section are to:
— give an overview of the various types of tasks that are part of DNV’s qualification management and fitness
for service verification services
— give guidance on the selection of relevant scope of work for qualification of new technology.
A 200 Introduction to DNV’s services
201 DNV’s possible roles in the qualification process may be divided into three categories:
— qualification management
— fitness for service verification
— qualification execution.
202 Qualification management is a service where DNV assists the client in the facilitation of the qualification
process described in Sec.2. This implies that DNV carries out a substantial part of making plans, preparing and
chairing work shops, proposing methods for uncertainty reductions and documentation of the process.
203 Fitness for service verification involves being an observer to the qualification process described in Sec.2
as well as verifying technical documentation and witness tests to an extent necessary to issue the DNV
qualification statements.
204 Fitness for service verification shall not be carried out on technology where DNV has ownership or has
commercial interests in any way other than being compensated for the value of the provided service.
205 Qualification execution comprises the types of work needed to create the various types of information,
such as:
—
—
—
—
—
—
providing technical expertise in failure mode identification and risk ranking
technical analyses and studies
laboratory testing
development of models for failure mechanisms
development of plans and specifications for analyses and testing to be carried out by DNV or others
risk and reliability analyses.
A 300 Combined roles in the qualification process
301 DNV may, as a fully independent company, provide services where any of the roles defined in A200 are
combined to maximise the value of the services to the Client without threatening DNV’s integrity.
302 When qualification execution tasks are provided in combination with fitness for service verification
different personnel will be used in the different roles in order to maintain the integrity of DNV as an
independent verifier. Further, the verifier shall be involved during the whole qualification execution process in
order to proactively comment on issues before they become irrevocable.
A 400 Combined roles in the qualification process
401 Technology Qualification Services may be executed as an integral part of product certification, see Sec.1
B104 with guidance note.
B. Qualification Management
B 100 Definition of qualification basis
101 The qualification basis may be development predominantly by DNV or written by the client and
reviewed by DNV.
102 Input for the qualification basis may include design basis or functional specification, which includes a
description of the following items as relevant, but not limited to:
—
—
—
—
general system description
functional limitations and main data
authority requirements
main principles for storage, transportation, installation, commissioning, operation and maintenance as well
as abandonment

see note on front cover
interfacing system requirements
environment
functional loads
main principles for manufacturing and quality assurance
reliability targets
health, safety and environment (HSE) requirements.
B 200 Technology assessment
201 The technology assessment may be carried out by DNV with input from and comments by the client or
be carried out by the client and commented by DNV.
202 The input for the technology assessment shall be the qualification basis with supporting documents as
listed below (but not limited to):
—
—
—
—
—
—
203
detailed drawings of items subject to qualification
drawings and description of control and safety systems
material specifications
outline fabrication procedure(s)
outline installation procedure(s)
outline inspection and maintenance procedure(s).
The technology assessment shall include the main tasks listed in Sec.2 B300.
B 300 Failure mode identification and risk ranking
301 The failure mode identification and risk ranking process should be managed by DNV in cooperation with
the client. This involves:
—
—
—
—
general preparations for the process
determination of probability and consequence classes and defining the risk matrix
arrange failure mode assessment involving relevant expertise
report the failure mode assessment.
302 The failure mode assessment should normally be conducted as workshops to be planned, chaired and
reported by DNV. However, for simple systems and components the failure mode assessment may be carried
out more rationally by in-office work where input and comments from the relevant expertise is achieved by
circulation of the records.
B 400 Concept improvement
401 When specified by the Client, DNV will call attention to identified areas for possible improvements or
risk reduction measures.
B 500 Selection of qualification methods
501 The selection of qualification methods may involve descriptions of the methods of qualification at
different levels of detail depending on the purpose of the assessment.
502 In this context a brief description of the qualification methods implies a minimum level of details
necessary to serve as a basis for the PoS evaluation and for later development of detailed descriptions of the
qualification methods. In particular, this implies that the means and purpose of the data collection must be
described unambiguously.
503 In this context a detailed description of the qualification methods implies that the data collection is
described at a procedure level necessary to carry out the activities and obtain satisfactory results.
B 600 Success evaluation
601 The success evaluation may be carried out at various levels of sophistication depending on the client's
needs for information into their own decision process and accessibility to input parameters.
602 The evaluation will normally be assessed on a qualitative basis with respect to technical challenges and
available time to qualification. When given as a quantitative estimate, this is referred to as the PoS.
603 A more sophisticated and informative assessment of the total PoS for the whole qualification may be
carried out in order to give the PoS as function of time. The assessment requires that a qualification execution
plan, that includes all qualification activities, is prepared and that both the probability of a successful outcome
for each activity, and the uncertainty in the durations are estimated.
604 An economic assessment of the qualification activities may be carried out following the same principles,
where the time parameter is replaced by costs. This requires that cost estimates with uncertainties are estimated
for each qualification activity.

Sec.3 – Page 13
B 700 Data collection (analyses and testing)
701 The data collection shall be carried out by the client and/or the client’s subcontractor unless
subcontracted to DNV as qualification execution (see D).
702 For the purpose of issuing a DNV certificate of fitness for service it is required that DNV is involved in
the data collection phase to an extent necessary to testify that the analyses and tests have been executed
according to the technology qualification plan and that results are derived and reported correctly. This
involvement shall be agreed upon in each individual case.
B 800 Functionality assessment
801 For the purpose of issuing a DNV certificate of fitness for service, DNV shall review and evaluate the
functionality assessment against the qualification basis, to confirm that compliance with the functional
requirements and reliability targets has been adequately documented.
C. Fitness for Service Verification
C 100 General
101 The objective of the fitness for service verification is to testify that the technology qualification process
has been executed in accordance with this OSS and the principles outlined in DNV-RP-A203. Additionally,
that the functional requirements and reliability targets as stated in the qualification basis have been adequately
addressed, as relevant, at the given stage of the qualification process.
102 The fitness for service verification may be carried out as a separate service or integrated with
qualification management.
103 When carried out as a separate service DNV may carry out the fitness for service verification in parallel
with the client’s qualification process. As a minimum, DNV shall take part in the failure mode and risk ranking
process or compensate for DNV’s absence by alternative arrangements.
104 DNV may on this basis issue statements as outlined in E400.
D. Qualification Execution
D 100 General
101 Qualification execution comprises the type of work needed to create the various types of information
required into the qualification process. The services may include
—
—
—
—
—
—
participation in failure mode identification and risk ranking with technical expertise
technical analyses and studies
development of models for failure mechanisms
development of plans and specifications for analyses and testing
testing
risk and reliability analyses.
E. Service Deliverables
E 100 General
101 The main DNV deliverables are shown schematically in Figure 1. The deliverables can be seen in relation
to typical milestones in offshore field development projects, where information from the qualification of new
technology process is needed as an basis for decisions (“decision gates”), as schematically illustrated in Figure
2. It is shown that the milestones for the qualification process may depend on whether the new technology is
regarded as an alternative to an available qualified technology or the feasibility of the development project is
dependant on the new technology to be qualified.
E 200 Milestones in the qualification process
201 The milestones in the qualification process are:
TA - Finalisation of the technology assessment.
TQP - Completion of the technology qualification plan.
TQ - Technology qualified.
E 300 Qualification management – DNV reports
301 At each of the milestones the qualification management service leads to the following DNV reports,
unless agreed otherwise:

Amended October 2011
see note on front cover
At TA - Technology assessment report.
At TQP - Technology qualification plan.
At TQ - Technology qualification report.
E 400 Fitness for service verification – DNV statements and certificates
401 Fitness for service verification may lead to the following statements and certificates (see Figure 2) based
on the criteria given in 402 to 405:
At TA - Statement of feasibility.
At TQP - Statement of endorsement.
At TQ - Certificate of fitness for service.
Layouts of these statements are shown in App.A.
402 The statements in 401 shall be based on the respective reports listed in 301 or similar report(s).
403 Following a technology assessment, a statement of feasibility can be issued provided that the new
technology is considered conceptually feasible (see definition in Sec.1 C311), and thereby suited for further
development and qualification according to the principles outlined in DNV-RP-A203.
Guidance note:
There is an established practice by classification societies, in particular within the maritime industry, to issue a
certificate titled “Approval in Principle”. An “Approval in Principle” may be issued as equivalent to a “Statement of
Feasibility” when properly referring to this OSS.
---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---
404 At the TQP milestone, a statement of endorsement is issued provided that it is found that the new
technology can be proven fit for service (see definition in Sec.1 C303) through the remaining planned
qualification activities.
405 At the TQ milestone, a certificate of fitness for service is issued provided that the new technology is
considered fit for service (see definition in Sec.1 C303).
F. Determination of Scope of Work
F 100 Introduction
101 The extent of involvement by DNV in the various activities within qualification management and fitness
for service verification may vary depending on the complexity of the technology, the maturity of the concept
and the client’s needs for information into their own processes. Various activities have been described in order
to form a basis for selection of services to be included in DNV’s scope-of-work for a particular project. The
services are tabulated in App. B as a form for selection of services.
102 In order for DNV to provide services in line with the client’s needs good lines of communication need
to be established at start-up of the project. A check list intended to be used at project start-up is given in App.
C, to aid in this process.
