2 Objective

The objective of this technical standard is to ensure a consistent design for the fabrication and installation of valves, across all new and existing Company facilities with regards to safety, the environment, operability and maintainability. 3 Scope

3.1 General

This technical standard shall apply to all new installations, and to modifications and extensions to existing Company facilities, both onshore and offshore. The standard shall apply during all project stages including, but not limited to, conceptual, FEED, detailed design, procurement, construction and commissioning.

3.2 Existing Facilities

When applying MOTS in connection with modifications and extensions to existing Company facilities built to other specifications, the user shall exercise engineering judgement necessary for ensuring compatibility with existing conditions, and ensure that the required quality and safety is achieved.

However, this technical standard is not retroactive, although it may be used as a reference point for performing an audit or gap analysis of existing facilities. When significant deficiencies compared to industry practice and accepted safety levels, etc., are found on existing facilities, then the improvements shall comply with MOTS.

3.3 Deviations

Deviations from this technical standard shall not be permitted unless prior written approval is obtained from the relevant Technical Authority, in compliance with MOG-EP-GEN-PRO-0203: Technical Authority and Waiver Procedure. Proposals for deviations shall be prepared only when:
