DNV-OSS-301 Certification and Verification of Pipelines

Sec.2
D. Information Flow
Sec.2
D 100 Communication lines
Sec.2 D
101 Communication lines are illustrated in Figure
2. Which lines that are open for communication depends on
the particular contractual agreements.
Sec.2 D
102 For instances where DNV (3rd party) does not have a contract
with the owner (1st party), DNV recommends strongly that the owner,
through his contract with the 2nd party, secures a direct communication
line from DNV to owner and vice versa.Guidance note:
The recommendation springs from DNV's experience
with projects where communications difficulties between the parties have
jeopardised the issue of the pipeline certificate.---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---

D 200 Obligations
Sec.2 D
201 In order to achieve the purpose and benefits of certification
the involved parties shall be mutually obliged to share and act
upon all relevant information pertaining to the certification scope.
Sec.2 D
202 The owner shall be obliged to:| — | inform DNV about the basis for
selecting the level of certification and the investigations and
assumptions made in this context |
| — | give DNV full access to all information concerning the certification
scope for the pipeline system and ensure that clauses to this effect
are included in contracts for parties acting on behalf of the owner
and parties providing products, processes and services covered by
the certification scope |
| — | ensure that DNV is involved in the handling of deviations from
specified requirements within the certification scope |
| — | act upon information provided by DNV with respect to events
or circumstances that may jeopardise the pipeline system and/or
the purpose and benefit of certification |
| — | ensure that the safety objective established for the
pipeline project is known and pursued by parties acting on behalf of
the owner and parties providing products, processes and services
covered by the certification scope. |
Sec.2 D
203 2nd parties shall
be obliged to:| — | perform their assigned tasks
in accordance with the safety objective established for the pipeline

opinion of DNV, the basis for selecting the level of certification

the opinion of DNV, may jeopardise the pipeline system and/or
the purpose and benefit of certification |

certification scope. |
Sec.2
D 300 Notification of certification
level
Sec.2 D
301 An assessment of the required level of certification for a project
should be made by the owner before preparing tender documents for
design and construction activities. The owner can then specify this
level in Invitation to Tender. This will give contractors clear
guidance and reference when estimating the extent and cost of efforts
associated with certification activities.
Sec.2 D
302 The required level of certification can be assessed by the owner
using this OSS. However, if the owner requires the contractor to
carry out this assessment as part of his response to an Invitation
to Tender (ITT) the owner should provide the necessary information
to enable the contractor to carry out this work. This information
should include overall safety objectives for the pipeline system
as well as particulars, such as temperatures, pressures, contents
and environmental criteria, commonly contained in a design brief.Guidance note:
Frequently, ITTs contain one line stating "....
the contractor shall arrange 3rd party verification." The
use of the information contained in the above paragraphs should
assist the owner to specify the required level of certification
more precisely.
On other occasions, certification is arranged by the owner
but, in this case, it is important that contractors are informed
of the level of certification planned.
The contractor's technical activities should not
be affected greatly by the contractual arrangements, aside from
whether or not the owner or the contractor assesses the required
level of certification.
There will be a small administration workload regarding document
control or meetings and discussions with the verifier but the contractor
can plan what documents are need to be seen by the verifier using
the information in this OSS. However, it is emphasised that the
verifier should not need to review any document that the contractor
would not produce normally when following the requirements of DNV-OS-F101.---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
