    Guide to electrical power and control systems for DP published by IMCA

    Projects and Operations // May 3, 2011

    Updating of guidance documents is high on the International Marine Contractors Association’s (IMCA) agenda in order to keep abreast of technological advances. Consolidating documents is also important, ensuring that all the answers on a particular topic lie in just one document rather than in several.
    ‘A guide to DP electrical power and control systems’ (IMCA M 206), recently published by IMCA for those who design, assess and maintain dynamically positioned (DP) diesel electric engines, combines both consolidation and updating, for it brings together three DPVOA/IMCA guidance documents: ‘Reliability of electrical systems on DP systems’ (126 DPVOA); ‘Power system protection for DP vessels’ (108 DPVOA); and ‘Power management system study’ (IMCA M 154). These closely related documents were published between 1992 and 2000.
    “The information in the new guide is relevant to a wide variety of users including vessel owners and operators, clients, classification and inspection auditors, and consultants,” explains IMCA’s Technical Director, Jane Bugler.

    “For each of these users, there will be information in the guide that is useful to managers, marine departments, vessel crew, procurement personnel, and frontline engineers, for it discusses the DP system focusing on the electrical components and covers power generation, power management, power distribution, vessel management systems, thruster drives and controls, and safety systems; and also features a useful five-page abbreviations list.
    “The guide contains aides-memoire, recommendations for studies and further analysis, comparisons and other material which will help users to deliver their work better toward building, running and maintaining safe and efficient DP vessels,” she adds.
    IMCA members can download the document free of charge from the members-only website with printed copies available at £15.00 for members and £30.00 for non-members. Copies can be ordered from or; or from IMCA at 52 Grosvenor Gardens, London SW1W 0AU, UK. Tel: +44 (0)20 7824 5520; Fax: +44 (0)20 7824 5521.
