Offshore Survey

This document provides guidelines for the shared use of sensors for Remotely Operated Vehicle (ROV) and survey purposes, highlighting considerations for efficiency, risk management, and technical requirements.

This document provides guidelines on the shared use of sensors for survey and positioning purposes, highlighting the importance of performance, redundancy, and risk mitigation.

This document provides comprehensive guidance on the planning, execution, and reporting of subsea spoolpiece metrology, with information on nine key metrology methodologies used to obtain dimensional data for the design and installation of subsea pipeline connections.

It covers the key principles, equipment and methodology, including:
 

• long baseline acoustics

• diver taut wire

• digital taut wire

• photogrammetry

• INS

• acoustically aided INS SLAM

• sonar

• static subsea LiDAR, and

• dynamic laser scanning.

The document is intended as informative guidance for surveyors, engineers, and contractors, helping them select appropriate metrology methods and understand their impact on fabrication tolerances and operational safety.
