Pipeline Works Authorisations

A pipeline works authorisation or variation should be in place before any pipeline or pipeline system construction or modification works of begins.

The Pipeline Safety Regulations 1996 were introduced by the Health and Safety Executive; as part of a consolidation exercise, the Petroleum Act 1998 repealed and replaced the Petroleum and Submarine Pipelines Act 1975 and the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Regulations came into effect in 1999. All have had an impact on the offshore Pipeline Works Authorisation (PWA) process.

A pipeline works authorisation or variation should be in place before any pipeline or pipeline system construction or modification works begins. Before submitting an application, we recommend that, the prospective owner informally consults both the OGA Consents team and the Health and Safety Executive at the earliest possible opportunity, to discuss the proposed scheme and the regulatory requirements.

Where there are no objections, it takes approximately four to six months from receipt of a satisfactory application to issuing the authorisation. In the case of pipelines in respect of which an environmental statement is required under the Offshore Petroleum Production and Pipelines (Assessment of Environmental Effects) Regulations 1999, the procedure may take longer. Operators must therefore submit applications at least four to six months before construction begins.
