Description
This document provides a global common industry technical specification for surface positioning sensor and system calibration and verification, during mobilization and on an ongoing basis. It covers the Online Survey and Positioning System, Global Navigation Satellite Systems (GNSS), Attitude and Heading Reference Systems (AHRS) and Inertial Navigation System (INS). It is intended to be included in contract documentation throughout the offshore energy industry, including relevant renewables activities. This includes seismic, site, and route surveys, rig and well positioning, asset inspection, and the full range of construction survey and positioning (S&P) support. A supporting guideline to this document provides additional technical guidance and recommendations, to assist with delivery of projects according to this specification.
