DNV-OSS-202 Verification for Compliance with UK Shelf Regulations
|
Sec.1
A. Introduction
Sec.1
A 100 General
Sec.1 A
101 DNV Offshore Classification aims to assure safety and reliability
of offshore units and installations with regard to design, construction
and operation. Wherever possible DNV offers additional, integrated
services to assist clients toward fulfilling regional statutory
requirements, including credit for classification standards and activities.
Sec.1 A
102 This Offshore Service Specification gives a general statement
of DNV services related to the core compliance issues for owners
and operators of units and installations wishing to enter and operate
in UK waters.Sec.1
A 200 Background
Sec.1 A
201 The UK Safety Case Regulations (SCR) and Prevention of Fire
and Explosion, and Emergency Response Regulations (PFEER) require
that all major accident hazards pertaining to an offshore installation
are identified and adequately managed throughout the installation
lifecycle. This is achieved by a combination of assessing and verifying
an acceptable standard of integrity of the installation, safety
of operation and protection of personnel.
Sec.1 A
202 The regulations establish a 'goal setting' (non-prescriptive)
approach which enables appropriate effort to be focused on those
items which provide the greatest contribution to safety. The principal
aims of the regulations are to:- Identify all credible hazards
relating to an installation, and eliminate hazards through design
where possible.
- Assess and reduce risks from major accident hazards
to a level that is as low as reasonably practicable (ALARP).
- Identify, implement and maintain an appropriate combination
of inherent safe design, prevention, detection, control, and mitigation
measures, for the management of these risks throughout the lifecycle
of the installation.
- Ensure that systems and equipment provided to protect
personnel in an emergency are suitable and capable of responding
to all foreseeable safety-related incidents.
- Ensure that design, operation, maintenance and verification
of safety measures and systems are undertaken by competent people
who understand the significance of the systems in the management
of hazards and possible escalating events.
- Assess changes to the installation which may affect
the risks, and revise the systems where necessary to take account
of the changes.
Sec.1 A
203 To demonstrate compliance with the above requirements, the
duty holder must formally document:| — | safety case(s) and background
assessments |
| — | PFEER assessment |
| — | record of safety-critical elements and their performance
standards |
| — | verification scheme for safety-critical elements. |
A summary of the key requirements is given in Appendix A.
The PFEER written scheme of examination, the SCR record of
safety-critical elements, and the SCR verification scheme require
the input of an independent and competent person.
Sec.1 A
204 Industry practice and work processes have led to a single
Scheme which satisfies the requirements of PFEER and SCR written
scheme requirements.
Sec.1
A 300 Scope and objective
Sec.1 A
301 As the UK regulations are now fully "goal setting" and
aim for continuing safety improvement, the regulations cannot be
fully transferred into standardised technical requirements. However,
it is possible to identify major points to be considered, and to
provide services toward fulfilment. The objective of this document
is to provide a general statement of the services DNV can provide
for UK compliance, with reference to how these services can be used
with classification. This includes:- Consultancy
Services:
Safety engineering during design and construction, risk analysis
and assessment, PFEER assessment, identification of safety-critical
elements and performance standards, ALARP methodology, safety case preparation. - Verification Services:
Actions as appointed independent and competent person (ICP)
for identification and review of list of safety-critical elements
and performance standards, drafting or review of written schemes,
implementation of verification activities, maintenance and revision
of written schemes. It is permitted in the Regulations that the
ICP is involved in the drafting on the Performance Standards.
Detailed information on these services can be obtained based
on discussions for specific installations and/or client
needs.
