Offshore positioning guidelines
The former UKOOA (UK Offshore Operators Association) document, Guidelines for the Use of GPS in Offshore Surveying, has been jointly revised by the International Association of Oil & Gas Producers (OGP) and the International Marine Contractors Association (IMCA).
Comprising seven sections, the new version opens with a summary of available systems followed by present techniques and a summary of various augmentation methods available from a variety of service providers. Practical guidance is also outlined in sections dealing with installation and operational issues as well as geodetic considerations and atmospheric and other environmental influences. Supplementary issues covered include quality assessment and statistical testing as well as recommended standards of competence for operators and users.
Copies of the updated publication, now entitled Guidelines for GNSS Positioning in the Oil & Gas Industry, can be downloaded for free from either www.ogp.org.uk or www.imca-int.com/documents. Printed copies can also be obtained via IMCA’s website.
