Guidelines for offshore oil and gas installations that are not permanently attended

This guidance updates and revises Guidelines for offshore oil and gas installations that are not permanently attended ('NPAI guidelines'), first published in 2010.

The aim of this document is to provide all those involved in designing and operating such installations with guidance on how to balance the commercial aspects of consistent operation with maintaining safe and environmentally acceptable practice through encouraging the use of risk-based decision making and provision of knowledge and experience. These guidelines therefore provide a framework to help designers and NPAI operating companies maximise the returns on investment whilst maintaining a safe, environmentally responsible and legally compliant operation.

This guidance is particularly intended for operations managers and support personnel, integrity engineers, maintenance managers, designers of new builds and those involved in the transition of permanently attended installations (PAI) to NPAI status (and vice versa).
