This book is an adaptation of the Guidelines for Offshore Marine Operations, which were published as Revision 0611-1401 on 06 November 2013. References to the Guidelines or Guidance is made to direct the reader to the appropriate section of the original publication. The objective of this publication, therefore, is to provide said guidance regarding the best practices which should be adopted to ensure the safety of personnel on board all vessels servicing and supporting offshore facilities, and to reduce the risks associated with such operations. It particularly relates to the following activities:

• Operations of offshore facilities.
• Operations of vessels.

Whilst the best practices summarised in this publication primarily reflect those adopted in the North-West European Area, the editor recognises that the guidance may just as easily apply outside this region and that many, if not all, of the recommendations included do indeed have global relevance. Where it has been possible to make recommendations relating to operations outside its core area without diluting the original objectives these have been included. It is recognised, however, that in certain circumstances local or company-specific requirements may exist.
In this event the guidance contained herein should be read in the context of such requirements and interpreted accordingly.
To facilitate common practices on a global basis, where necessary, the guidance, together with included reporting forms, should be used as the basis for preparing procedures for local practices.
