Guidelines for lifting operations

1 IMCA SEL 019, IMCA M 187 October 2007 Guidelines forLifting OperationsABThe International MarineContractors International Marine Contractors Association (IMCA)is the international trade association representing offshore,marine and underwater engineering promotes improvements in quality, health, safety,environmental and technical standards through the publication ofinformation notes, codes of practice and by other are self-regulating through the adoption of IMCA Guidelines as appropriate. They commit to act as responsiblemembers by following relevant Guidelines and being willing to beaudited against compliance with them by their are two core activities that relate to all members: Safety, Environment & Legislation Training, Certification & Personnel CompetenceThe Association is organised through four distinct divisions, eachcovering a specific area of members interests.

2 Diving, Marine,Offshore Survey, Remote Systems & are also four regional sections which facilitate work onissues affecting members in their local geographic area Americas Deepwater, Asia-Pacific, Europe & Africa and MiddleEast & 019, IMCAM 187 These Guidelines were prepared for IMCA under the direction ofits Marine Division Management thanks its members for their valuable contributions indeveloping this information contained herein is given for guidance only and endeavours to reflectbest industry practice. For the avoidance of doubt no legal liability shall attach to anyguidance and/or recommendation and/or statement herein for lifting OperationsIMCA SEL 019, IMCA M 187 October 2007 Definitions.
