GUIDELINES FOR MARINE LIFTING OPERATIONS PREFACE This document has been drawn with care to address what are likely to be the main concerns based on the experience of the GL Noble Denton organisation.

In using this document, it should be treated as giving guidelines for sound and prudent practice on which our advice should be based, but guidelines should be reviewed in each particular case by the responsible person in each project to ensure that the particular circumstances of that project are addressed in a way which is adequate and appropriate to ensure that the overall advice given is sound and comprehensive. Whilst great care and reasonable precaution has been taken in the preparation of this document to ensure that the content is correct and error free, no responsibility or liability can be accepted by GL Noble Denton for any damage or loss incurred resulting from the use of the information contained herein. © 2010 Noble Denton Group Limited, who will allow: the document to be freely reproduced, the smallest extract to be a complete page including headers and footers but smaller extracts may be reproduced in technical reports and papers, provided their origin is clearly referenced. 0027/ND REV 9 Page 2
