Parent topic: Chapter 21 Guidelines on Scope of Survey Certification of Safety Critical Equipment

1.1 Application

1.1.1 This document has been extracted from standard LR Group Oil and Gas project Verification Work Instructions, for issue as part of the LR Quality System and should be read in conjunction with Project-Specific Quality Plan and supporting procedures. It is intended to outline appropriate scopes of survey for typical safety critical items of equipment associated with disconnectable or mobile drilling and production installations where LR is providing Certification or Verification/Validation services. The list is not exhaustive and should be used as a guide for equipment which is to be included within the scope of the service to be provided. The extent to which the Surveyors are required to attend in order to ensure that each item of equipment complies with a recognised Code, specification, or agreed Standard of performance is to be agreed with LR. The attendance required will be indicated on the supplier’s Inspection and Test plan as a minimum. The procedures between Project Vendors and their local LR Surveyors are to be agreed.

1.1.2 Some typical acceptable Codes and Standards are referenced herein. Other National or International Standards may be considered and accepted if deemed appropriate by LR. Company standards may also be applied where they represent an agreed standard of performance. See also Pt 12, Ch 1 Recognised Codes and Standards.

1.1.3 Where equipment is identified as being safety critical to an installation, survey/examinations undertaken within their examination schemes or codes may be considered to contribute to the validation required of such equipment. Safety critical equipment/elements are those such parts of an installation and such parts of its plant (including computer programs), or any part thereof;
  1. The failure of which could cause or contribute substantially to; or
  2. A purpose of which is to prevent, or limit the effect of, a major accident.
