SIGTTO Floating LNG Installations

Published: March 2021

The purpose of this document is to provide guidance that covers all stages in a floating LNG installation project, from accurate assessment of the site through to safe operational status.

This document covers two critical areas when considering floating LNG installations:

1. Technical assessment

2. Operations

The technical assessment section provides guidance on the considerations for a floating LNG installation project. This includes pre-front-end engineering design and front-end engineering design (pre-FEED/FEED) data collection and design criteria, physical location and site assessment, the applicable floating LNG installations to

consider and project overview from commissioning to end of life.

The operations section reinforces best practices for the safe operation of floating LNG installations and their associated infrastructure. Recommendations are based on mitigating identified risks and hazards.
