they occur (possibly at irregular periods in time), however within the pulse train all bit
transmissions occur at a fixed rate. An example which illustrates this is typing at a keyboard, not
all keys are pressed regularly, however whenever one key is pressed all the bits representing that
key are transmitted at a fixed rate. Confused? You are not alone. See Synchronous (IT,

Bits. Binary digITS. A bit is a binary digit, the smallest unit of information a computer uses. It is
expressed as 1 or 0, meaning on or off, yes or no, positive or negative, something or nothing.
Seven bits are required to store one alphabet character in the ASCII character code set, (in
addition one start bit, one parity bit, and one stop bit). One and zero are represented by pulse
levels where zero is a low pulse, and one is a high pulse. The purpose of the parity bit is to allow
detection of errors in data transmission or recording. There are various parity checking methods,
even parity check, odd parity check, longitudinal parity check, and probably others that I have
never heard of. See bytes, ASCII, EBCDIC, BCD Kb, Mb, Gb, Tb, Pb (IT, Units/1.05)

Boolean Algebra. The algebra of logic. An English mathematician called George Boole wrote a book
in 1854 called "An investigation of the laws of thought on which are founded the mathematical
theories of logic and probabilities". In this book Boole described an algebra system now called
Boolean algebra (sometimes switching algebra) for representing and manipulating logical
expressions. Digital computers are designed, maintained, and analysed using techniques based on
Boolean algebra. Variables in Boolean algebra can only assume one of two values, 0 or 1, True or
False, Something or Nothing, Positive or Negative, as opposed to algebra where variables can
assume any value in the range of real numbers. Claude E Shannon first applied Boolean algebra
as a method for representing circuits as a set of mathematical expressions in 1938 (IT,
Coding/1.05)

but as a necessity. In a nutshell changes to the scope of work can be identified by any member of
the project organisation. A project control group should be responsible for verifying that a
variation does exist and raising the appropriate change notification to the Client. The change
should be immediately distributed to the planning department and incorporated into the working
schedule, for calculation of any schedule impact. Changes that are not identified or notified to the
Client within a reasonable time, may be considered to be a part of the contractual scope of work.

Charpy Test. Metal Impact Test. A test performed on a sample piece of metal to show its resistance
to impact at low temperatures. Most steel plates become increasingly brittle as temperatures
decrease particularly below -20 F. This test is performed on a test coupon which is machined with
a v notch or keyhole cut in one side. The coupon is then frozen to the test temperature and
quickly placed in a clamp fixture, and struck with a pendulum hammer. The hammer is connected
to a gauge which registers the impact resistance of the coupon as it breaks. The resistance is
measured in FT-LBS energy (Petrochemical/1.05)

taken to protect the rig like applying protective coatings to fight corrosion and filling equipment
with protective fluids. The duration of cold stacking can vary depending on many factors, rigs that
are cold stacked or stacked up are typically out of service for a significant period of time and are
not considered to be readily usable. Bringing them back into service can incur considerable costs.

Conventional Memory. Main Memory. A CPUs storage area for processing. The first 640k of a PCs
main memory is called conventional or sometimes base memory. When PC’s were first developed
they were designed around a main memory size of 640k, a large amount in 1977. A particular
chip (CPU) can only address a given size of memory, for older chips this was 640k, newer chips
can address gigabytes (billions-us). Normally k means kilo or one thousand. The exception is of
course computers where 1k=1024, so 640k=655.360 bytes. For older PC’s Conventional memory
was reserved for storage in the following order, 1) the Basic Input Output System, 2) Disc

Digital Signal. A signal that only has two values during transmission. See Boolean and Analogue (IT,
Telecommunications/1.07)
Digital Signature. Confirmation of the identity of an electronic message sender. In theory a digital
signature is verifiable and non-repudiable, and ensures that the contents of an electronic message
(or transaction) has not been altered. Germany was the first country to pass a law on digital
signatures, (where the digital signature is not legally binding!?). My own views on this matter are
that cash can be stolen, travellers checks can be stolen, and credit cards can be stolen or used
without authorisation. If you deal on a bartering system your cows and goats can also be stolen!
At the end of the day who do you trust and who can rob you during the process of an exchange.
As a closing note smart cards, which are banking cards with a built in chip instead of a magnetic
strip, are widely in use in Europe and contain a type of digital signature called a unique key or
unique id which the card is never meant to reveal. (Has no one ever heard of torture). See SET,

(RFI). Crosstalk interference occurs when two cables are too close and cause disruption to each
other. Solutions are, move the cables further apart, use twisted pairs, use shielded cable, or fibre
optic cable. RFI is high frequency radiation produced by things like, radios, mobile telephones,
computers, motors. RFI can cause disruption with high speed digital circuits found in computers

ER-MODEL. Entity Relationship Model. This is a technique used to describe individual data entities,
and the relationship between them. ER modelling is a method of analysing, designing, and
describing a relational database. The attributes of each entity in the model eventually become
columns in a table, while relationships between entities become keys (one table pointing to
another). Another type of modelling is called object modelling. Object oriented analysis and
design assumes a process oriented approach rather than a data oriented one (IT,

ES. Early Start. Early start and finish dates are calculated during a forward pass of the network. If the
first activity starts on day 1 and has a duration of 5 days its ES will be day 1 and it's EF day 5.
Any activities succeeding it will start on day 6. However when the start of an activity is dependent
on more than one preceding activity it's ES date is the maximum EF date of the preceding
activities. EF = ES + Duration. The EF date of the last activity in the network is the expected
completion date of the project. The expected completion date represents the longest sequence of
activities in the network, this sequence of activities is called the critical path. See FS, SS, TF, FF,

able to describe this technological revolution in easy to understand terms. ESDRAM is the latest
emerging volatile memory type, along with believe it or not DDR-SDRAM. What it all boils down to
at the end of the day is something called bandwidth, which is how fast this piece of computer

Internet. Interconnection of computer networks that enables connected machines to communicate
directly. The term internet refers to a global interconnection of government, education, and
business computer networks that is available to the public. There also exists smaller internets,
usually for the private use of a single organisation, called intranets. Internet technology is a
primitive precursor of the Information Superhighway, which is a theoretical goal of computer
communications to provide schools, libraries, businesses, and homes universal access to quality
information that will educate, inform, and entertain. Internets allow information to pass between
computers, and a variety of services have been built upon this function. Including logging onto
and operating a computer from a remote location (telnet). Transferring files between a local
computer and a remote computer, File Transfer Protocol (FTP). Reading and interpreting files on
remote computers (gopher). The newest and most important internet service is Hyper Text
Transfer Protocol (HTTP), a descendant of the gopher service. HTTP can read and interpret files
on a remote machine, not only text, but pictures, sounds, and video information. HTTP is the
information transfer protocol that is the basis for the collection of distributed information called
the World Wide Web (IT, Internet/1.06)

Leak Test. Pressure Test. Pressurisation of a component by filling completely with nitrogen, or air
and applying an established amount of pressure with a pumping device. All openings must be
plugged or capped prior to test. Normally a pressure and temperature recording chart is hooked
up to the test unit to produce a permanent record of the test. The test pressure and duration
must be specified. Normally a leak test is combined with a soapy bubble test, where joints are
coated in a soapy water solution and visually inspected for bubbles. This type of test is associated
with hazardous operations, E.g. pipes carrying gas, aviation fuel hydrant systems

LS. Late Start. Late start and finish dates are calculated during a backward pass of the network.
Calculations are started with a completion date, which may be the expected completion date
computed during the forward pass, or a target completion date that is imposed. If the last activity
in the network has a LF on day 10 and a duration of 5 days its LS date will be day 6. Any activities
preceding it will have a LF date of day 5. However when the Late Finish of an activity is
dependent on more than one succeeding activity it's LF date is the minimum LS date of the
succeeding activities. LS = LF - Duration. The LS date of the first activity in the network is the
latest date that the project must start on if the objectives of the network are to be met. If the
expected completion date of the project calculated during the forward pass was used as the LF
date of the last activity in the network, then the LS date of the first activity in the network will be
equal to it's ES date. See FS, SS, TF, FF, ES, EF, LS, LF, Network, AON, AOA, CPM, CPA (Project

Macro. A series of special instructions for a program. Macros enable a user to automate repetitive

Macro virus. A self replicating piece of code written in an application's macro language. Macro
viruses are very easy to create or modify. The distinguishing factor that makes it possible to
create a virus with a macro is the existence of auto-execute macros in the macro language. An
auto-execute macro is one that is executed in response to an event such as opening or closing a
file, and not in response to an explicit user command. Once a Macro virus is running, it can copy
itself to other documents, delete files, and create general problems in a system. These things
occur without the user explicitly running the macro. Macro viruses spread by having one or more
auto-execute macros in a document. Opening or closing the document or using the "replace"
command, activates the virus macro. When the macro is activated, it copies itself and any other
macros it needs, to the global macro file NORMAL.DOT. After they are stored in NORMAL.DOT
they are available in all open documents. At this point, the macro viruses try to spread themselves
to other documents, usually by including an Autoclose macro that attaches the virus macro to the
document and saves it. The Macro viruses that cause damage contain a trigger that starts the
damage routines. The trigger is some event that the virus writer has programmed the virus to
watch for, such as a date or the number of days since the infection occurred (IT,

Measure of Capacity. There are three systems of measurement, the British imperial system, the US
liquid measure, and the US dry measure. Liquid and dry goods were once measured using
different systems with varying measures, wine gallon, ale gallon, Winchester bushel, etc. The
liquid measures used in the US today are similar to the now defunct wine gallon. While the
standard US bushel (dry measure) used in the US is similar to the defunct Winchester bushel. The
Imperial system for measuring capacity was established in England in 1824 for measurement of
both liquid and dry goods. The metric system of measurement is a lot easier than these systems
but is not as quaint. Eg. "We downed a hogshead of ale last night", loses a lot in the conversion
to "We downed 238,5 litres of pils last night" (Weights & Measures, Imperial/1.05)

Morgan. A great British sports car. (General/1.05)
Morgan. Welsh buccaneer. Sir Henry Morgan (1635-88), was born in Llanrhymny. It is believed that
he was kidnapped in Bristol when a boy and sold as a servant on the West Indian island of
Barbados. From there he worked his way to Jamaica, and joined the buccaneers, pirates who
preyed on Spanish settlements and shipping. By 1666 he was in command of his own vessel.
Commissioned by the governor of Jamaica to carry on hostilities against the Spanish, Morgan
captured and sacked settlements in Cuba, Panama, and Venezuela. He was brought to England in
1672 to be tried for plundering Panama City after a treaty had been signed between England and
Spain. Convinced of his loyalty, King Charles II knighted Morgan and appointed him lieutenant
governor of Jamaica. The difference between a buccaneer and a privateer is that a buccaneer is a
state sponsored pirate, whilst a privateer is a self employed pirate, ie. he is not bothered about
the nationality of the ships and settlements he plunders! Captain Morgan was the most feared
and renowned of the buccaneers, he achieved state recognition for his state commissioned
exploits against the Spanish. On the other hand Blackbeard (an Englishman) was the most feared
of the privateers, Blackbeard died a bloody death off the coast of America at the hands of two
English frigates (General/1.05)

OEM. Original Equipment Manufacturer. An OEM (original equipment manufacturer) is a company
that provides a component to another company for use in that company's brand name product.
Many computer hardware manufacturers that have their own brand-name products derive
considerable revenue by reselling the product or key parts of it to companies that seem to be
competing in the same market. Arguments for being an OEM are that you may be able to make
money from a market sector that your competitor already owns (perhaps because they have an
existing customer base) and that you can be a more efficient producer because you sell and
manufacture more of your product. Frequently, a company that incorporates OEM parts or
products differentiates itself from the OEM's brand-name products by adding features or using
different selling concepts (IT, Computing/1.05)

Optic fiber. A glass or plastic wire as thin as a human hair, which carries signals using pulses of light
emitted by a laser. Fibre optic cable is not subject to electro magnetic or radio frequency
interference, and is capable of carrying a lot more information than copper wire. Fibre optic cable
is constructed of a core which is the glass in the centre of the cable, and the region through
which the light pulses travel. A cladding which surrounds the core and keeps the light from
escaping the core, and a coating or sheath, which surrounds, protects, and acts as a cushion for
the glass fibre. Light travels fast and digital signals are based on pulses (imagine a Morse code
message). A laser can be turned on and off a billion times per second, and a single strand of glass
fibre can carry multiple wavelengths (different colours) of light simultaneously. See Boolean, Bits,
Twisted pair, Coaxial (IT, Computing/1.05)

Orifice Fitting. Any device which allows orifice plate insertion into and removal from a pipeline
without "breaking" the line. May be either a "deadline" fitting (pipe section must be depressurised
before plate removal) or a "liveline" fitting which allows plate removal under flowing conditions.
An orifice plate is used in gas metering runs to measure the volume of gas passing through the
run, this is achieved by measuring the pressure on both sides of the orifice plate, the differential
is then used to calculate the volume of gas transferred. This process is called custody transfer.

RAM. Random Access Memory. Semiconductor memory. Volatile. Each bit in RAM is represented by a
cell with one of two states (yes believe it or not, see Boolean and Bits). Each cell can be
electrically charged or not electrically charged representing 1 or 0 respectively. Semiconductor
memories are constructed in different ways. Examples are Bipolar, Static MOS, Dynamic MOS,
CMOS, Silicon On Sapphire, and Integrated Injection Logic. Static RAM does not require refreshing
with power due to power leakage. Dynamic RAM does require refreshing with power due to power
leakage (dissipation). A power failure empties the cell contents of both dynamic and static RAM.
The result is you loose whatever you were working on at the time, unless you’ve been smart and
backed up often. In PC terms it gets even more confusing because there are different �logical’
types of memory called conventional memory, upper memory, expanded memory, and extended
memory (IT, Computing/1.05)

SDRAM. Synchronous Dynamic Random Access Memory. Replacement for DRAM. Increases the
bandwidth fourfold. The latest type of PC memory architecture. SDRAM provides a significant
performance improvement over conventional Fast Page Mode (FPM) or Extended Data Output
(EDO). The main difference is that SDRAM is synchronised to the system clock signal, which
means that all operations run at the same speed as the processor bus, compared to conventional
memory architectures which run asynchronously to the processor bus. Due to this
synchronisation, data bits are retrieved faster and thereby increase system performance (IT,

Sour Gas (Liquid). Any Gas (or liquid) containing sufficient H2S (hydrogen sulphide) to be
considered sour. Actual amount of H2S is a variable depending on pressure and other parameters.
When a fluid is established as being sour, certain metallurgical considerations are required. One
of the main considerations is that of material hardness. H2S is not as much a corrosion problem
as it is a potential cause of metal failure (Sulphide Stress Cracking). Some metals are more
susceptible to SSC than others. Very small concentrations of H2S when breathed can be Fatal

Task. An item of work to be performed. A task is a detailed definition of the scope of work and is
related to an activity in a many to one, or possibly one to one relationship. Referenced
information for each task should include a work description, required engineering information,
material requirements and estimated man-hours. In addition codes to uniquely number the task
and identify it with it's corresponding activity, location, sub-system, the originator, and whether
the task is original contract scope or varied scope. Quite often the term task is misused to mean
activity, when infact tasks are a breakdown of an activity into smaller packets of work. For
example an activity maybe defined as 'Foundation for heat exchanger abc', the tasks for which
might be defined as, excavate, lean concrete, formwork, re-bar, anchor bolts, pour concrete,

Twisted pair. Two insulated copper wires twisted around each other, and incased in a sheath or
shield. If the shield acts as a ground (earth) the cable is called shielded twisted pair (STP). If it
does not act as a ground (earth) it is called unshielded twisted pair (UTP). Both wires are required
to transmit a signal. Usually more than one signal needs to be transmitted by a cable, this is
achieved by adding an extra pair of cables. The cable is then denoted as 2 par, or 4 par, etc.
Twisted pair uses a colour coding system, when multiple pairs are used. See crosstalk, EMI, RFI,
coaxial, fibre optic, STP, UTP (IT, Computing/1.05)

Also called graphics card. A Video board can be 16-bit, 32-bit, 64-bit or 128-bit, the higher the
bits the better the performance. The most frequently quoted feature of a video card by
manufacturer's is it's resolution, this is the number of pixels the card is capable of displaying on a
monitor eg. 1024 x 768. Refresh rate measured in Hz refers to the number of times the screen is
repainted per second. 1Mb of on board memory can display 8-bit colour (256 colours), 2Mb can
display 16-bit colour (65,000 colours), 4Mb can display 24-bit colour (16 million colours). See

WBS. Work Breakdown Structure. A hierarchical definition of the scope of work, where a work
package is an element of the WBS. As with most things a simple WBS works best. A common
WBS breakdown is into project phases, where work packages may be defined as Engineering,
Procurement, Fabrication, Installation, and Commissioning. These work packages might be further
sub-divided into disciplines, and then into elements of work, like procedures, drawings, studies.
Another approach is to define each work package as a major element of work. For example each
module in a North Sea platform. Each work package is then sub-divided into project phases, and
disciplines. There are of course many ways to skin a cat, and the most suitable breakdown will
ultimately depend on the type of project, and it's complexity (Project Management/1.05)

WWW. World Wide Web. The WWW is the multimedia part of the Internet. It is composed of
different web sites, which are created by people and organisations around the world on different
servers (computers). You can move from one web site to another with a browser, and search for
topics you are interested in. The WWW can be compared to a library, where Web sites are books,
and web pages are the pages in the books. WWW Pages can contain whatever information their
creators want to make available eg, news, pictures, movies, sounds, opinions, company profiles,
etc, etc, etc. These WWW sites can be located on servers anywhere in the world. The analogy
with a library ends when it comes to indexing, you can usually easily find the book you want in a
library! See Int A number of search engines have emerged to resolve this problem. See Internet,

37. Project Management
ACE. Actual Control Estimate.
ACQ. Annual Contract Quantity.
Activity. An element of work which forms the basic building block for a schedule/network. There are
different schools of thought on how detailed activity definition should be. A text I browsed
recently argued that too much detail is a waste of time and resources, a case of not being able to
see the wood for the trees. This maybe a valid point, however when my wife and I built our
house, we would not have dreamed of doing so without paying attention to detail, or being aware
of what we could expect for our money. See Task
Activity Calendar. An activities working pattern. An activity calendar defines the working and nonworking days applicable for an activity. For example engineers working a staff job in Europe might
be working 7,5 hours per day, 5 days a week, while construction personnel on a site in the desert
might be working 12 hours per day, 7 days a week. It is important to identify the working
patterns for different activities as these parameters will ultimately affect the schedule
Activity Description. A description of the work to be performed under the activity.
Activity ID. A unique reference number for the activity, required by most computerised planning
applications. In my opinion the number of characters should be kept to a bare minimum,
especially if man-hours are to be booked against them
Actual Finish Date. The actual date on which an activity is completed.
Actual Start Date. The actual date on which an activity commences.
ACWP. Actual Cost of Work Performed.
ADM. Arrow Diagramming Method. See AOA
AFC. Approved For Construction. A completed drawing that is released for construction after all
appropriate checks and controls have been performed. Same as IFC
AFD. Approved For Design. A drawing that is approved for design work. A typical example would be
P&IDs and PFDs
AFE. Approved For Engineering.
AFT. Approved For Tender.
AFWP. Actual Float on Work Performed.
AOA. Activities on the arrow. Arrow networks are diagrams where the activity is placed on the arrow,
between the nodes. The activities, together with the nodes and dummy activities (activities with
zero duration) represent the sequence in which activities will occur. The nodes for an arrow
network are drawn as circles, and dummy activities, (which act as constraints), are drawn as
dashed lines. See Network, AON, PERT, CPM, CPA
AON. Activities on the node. Precedence networks are diagrams where the activity is placed on the
node, and the arrows between the nodes represent the dependencies and sequence in which the
activities will occur. The significant difference from an arrow network is that dependencies of
different types are allowed. Finish to Start dependencies with negative lags, imply an overlap in
the activities. The nodes for a precedence network are drawn as rectangular boxes. See Network,
AOA, PERT, CPM, CPA
APO. Assigned Purchase Order. See PO
BAC. Budget At Completion. See EAC
Backward pass. The process of calculating late dates for a network. See CPA.
Bar Chart. See Ganttchart.
Baseline. A scheduling benchmark. A Project Control Baseline is the benchmark from which

the workshop, where the work bench was marked for measuring purposes. In effect a baseline is

Change. A modification to the scope of work. See Variation
Change Control. The recording, control, and notification of changes also called Variation Control.
Which ever side of the fence you are sitting on the registering and control of changes is very
important. Uncontrolled changes can be a financial disaster for a project. Quantity surveyors who
register and estimate the cost affect of project changes should not be considered as an overhead,
but as a necessity. In a nutshell changes to the scope of work can be identified by any member of
the project organisation. A project control group should be responsible for verifying that a
variation does exist and raising the appropriate change notification to the Client. The change
should be immediately distributed to the planning department and incorporated into the working
schedule, for calculation of any schedule impact. Changes that are not identified or notified to the
Client within a reasonable time, may be considered to be a part of the contractual scope of work.

Any activities succeeding it will start on day 6. However when the start of an activity is dependent
on more than one preceding activity it's ES date is the maximum EF date of the preceding
activities. EF = ES + Duration. The EF date of the last activity in the network is the expected
completion date of the project. The expected completion date represents the longest sequence of
activities in the network, this sequence of activities is called the critical path. See FS, SS, TF, FF,

LF. Late Finish. See LS for full description
LRE. Last Revised Estimate. LRE=ACWP+ETC
LS. Late Start. Late start and finish dates are calculated during a backward pass of the network.
Calculations are started with a completion date, which may be the expected completion date
computed during the forward pass, or a target completion date that is imposed. If the last activity
in the network has a LF on day 10 and a duration of 5 days its LS date will be day 6. Any activities
preceding it will have a LF date of day 5. However when the Late Finish of an activity is
dependent on more than one succeeding activity it's LF date is the minimum LS date of the
succeeding activities. LS = LF - Duration. The LS date of the first activity in the network is the
latest date that the project must start on if the objectives of the network are to be met. If the
expected completion date of the project calculated during the forward pass was used as the LF
date of the last activity in the network, then the LS date of the first activity in the network will be
equal to it's ES date. See FS, SS, TF, FF, ES, EF, LS, LF, Network, AON, AOA, CPM, CPA

however it depends on the quality of the logic that the network is built on and the size of it's
activities. See CPA, network, TF, ES, EF, LS, LF
Network. A network in a scheduling context is a chain of interconnected activities that describe the
sequence and the duration required to complete a particular project. A network is a model of the

Productivity Factor. A theoretical measurement of effectivness. The ratio of actual manhours
expended to estimated manhours earned. The formula is Productivity=Actual/Earned. If the value
is greater than 1 then productivity is poor, or the estimate is poor, or too little progress is being
claimed, etc, etc. On the other hand if the value is less than 1 then productivity is good, or there
is a lot of slack in the estimate, or too much progress is being claimed, etc, etc. As a footnote
some organisations calculate productivity factor as Earned/Actual which can be confusing
Project. An undertaking with a clearly defined goal, that is undertaken within a given time scale and
budget. Some contemporary texts on the subject attempt to argue that in addition, a project is a

WBS. Work Breakdown Structure. A hierarchical definition of the scope of work, where a work
package is an element of the WBS. As with most things a simple WBS works best. A common
WBS breakdown is into project phases, where work packages may be defined as Engineering,
Procurement, Fabrication, Installation, and Commissioning. These work packages might be further
sub-divided into disciplines, and then into elements of work, like procedures, drawings, studies.
Another approach is to define each work package as a major element of work. For example each
module in a North Sea platform. Each work package is then sub-divided into project phases, and
disciplines. There are of course many ways to skin a cat, and the most suitable breakdown will
ultimately depend on the type of project, and it's complexity
