Sec.1
E. Definitions
Sec.1
E 100 General
Sec.1 E
101 The definitions in DNV-OS-F101 section 1 C200 also apply to
this OSS.
Sec.1 E
102 The most important definitions from DNV-OS-F101 applied in
this OSS are repeated. They are marked "(DNV-OS-F101)" between
the word and its definition, ref. e.g. verification.Sec.1
E 200 Verbal forms
Sec.1 E
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.
Sec.1 E
202 Shall: Indicates requirements
strictly to be followed in order to conform to this OSS and from
which no deviation is permitted.
Sec.1 E
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.
Sec.1 E
204 Will: Indicates a mandatory
action or activity to be undertaken by DNV. (Ref. "shall" for
other parties.)

Sec.1
E 300 Definitions
Sec.1 E
301 Certificate of Conformity: A
document signed by a qualified party affirming that, at the time
of assessment, the product or service met the stated requirements
(BS 4778: Part 2). Guidance note:
For this OSS, the document is a DNV Submarine Pipeline System
Certificate of Conformity and it is signed by DNV.
This OSS allows, under special agreement, the DNV Submarine Pipeline
System Certificate of Conformity to be issued with a validity period
past the date of issue.
For this OSS, a Certificate is a short document (often a single page)
stating compliance with specified requirements. The results from
associated verification shall be contained in a separate (single
or multiple volume) report.---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
Sec.1 E
302 Certification: Used
in this document to mean all the activities associated with process
leading up to the Certificate.Guidance note:
In this OSS when Certification is
used it designates the overall scope of work or multiple activities
for the issue of a Certificate, whilst Verification is
also used for single activities associated with the work. This in
essence means that Certification is Verification for which the deliverable
includes the issue of a Certificate.
Other (related) definitions are:
BS 4778 Part 2. Certification: The
authoritative act of documenting compliance with requirements.
EN 45011. Certification of Conformity: Action
by a third party, demonstrating that adequate confidence is provided
that a duly identified product, process or service is in conformity
with a specific standard or other normative document
ISO 8402 1994. Verification: Confirmation
by examination and provision of objective evidence that specified
requirements have been fulfilled.---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
Sec.1 E
303 Client: DNV's
contractual partner. It may be the purchaser, the owner or the contractor.
Sec.1 E
304 Construction phase (DNV-OS-F101):
All phases during construction, including fabrication, installation,
testing and commissioning, up until the installation or system is
safe and operable for intended use. In relation to pipelines, this
includes transportation, on-shore and on-barge welding, laying,
rectification, tie-in, pressure testing, commissioning and repair.
Sec.1 E
305 Design (DNV-OS-F101):
All related engineering to design the pipeline including both structural
as well as material and corrosion.
Sec.1 E
306 Design phase: An initial
pipeline phase that takes a systematic approach to the production
of specifications, drawings and other documents to ensure that the
pipeline meets specified requirements (including design reviews
to ensure that design output is verified against design input requirements).
Sec.1 E
307 DNV Submarine Pipeline System Certificate
of Conformity: see A.101.
The term 'the pipeline certificate' is used in
the text of this OSS.
Sec.1 E
308 Fabrication (DNV-OS-F101):
Activities related to the assembly of objects with a defined purpose.
In relation to pipelines, fabrication refers to e.g. risers, expansion
loops, bundles, reels, etc.
Sec.1 E
309 Hazard: A deviation
(departure from the design and operating intention) which could
cause damage, injury or other form of loss (Chemical Industries
Association HAZOP Guide).
Sec.1 E
310 HAZOP (HAZard and OPerability
study): The application of a formal systematic critical examination
to the process and engineering intentions of new or existing facilities
to assess the hazard potential of mal-operation or mal-function
of individual items of equipment and their consequential effects on
the facility as a whole (Chemical Industries Association HAZOP Guide).
Sec.1 E
311 Installation (activity)
(DNV-OS-F101): The operations related to installing the equipment,
pipeline or structure, e.g. pipeline laying, tie-in, piling of structure
etc., including final testing and preparation for operation.
Sec.1 E
312 Manufacture (DNV-OS-F101):
Making of articles or materials, often in large volumes. In relation
to pipelines, refers to activities for the production of linepipe,
anodes and other components and application of coating, performed
under contracts from one or more Contractors
Sec.1 E
313 Operations (phase): The
phase when the pipeline is being used for the purpose for which
it was designed.
Sec.1 E
314 Risk (DNV-OS-F101):
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.
Sec.1 E
315 Risk Reduction Measures: Those
measures taken to reduce the risks to the operation of the pipeline
system 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.Guidance note:
The usual order of preference of risk reduction measures is:- Inherent safety
- Prevention
- Detection
- Control
- Mitigation
- Emergency response.

Sec.1 E
316 Safety Objectives: The
safety goals for the construction, operation and decommissioning
of the pipeline including acceptance criteria for the level of risk
acceptable to the owner.
Sec.1 E
317 Statement of Compliance: A
statement or report signed by a qualified party affirming that,
at the time of assessment, the defined pipeline phase, or collection
of activities, met the requirements stated by the owner.
Sec.1 E
318 Verification (DNV-OS-F101):
An examination to confirm that an activity, a product or a service
is in accordance with specified requirements.Guidance note:
The examination shall be based on information, which can be proved
true, based on facts obtained through observation, measurement,
test or other means.
