Example specification for a DP FMEA for a new DP vessel (IMCA M 219) is a newly published document from the International Marine Contractors Association that provides, as the title indicates, an example of a specification for a dynamic positioning (DP) failure modes and effects analysis (FMEA) of a new DP vessel to be carried out prior to vessel delivery, probably by the shipyard as a contractual deliverable to the new owner. This first FMEA should be seen as a benchmark for subsequent analyses.
“The objective of the FMEA is to identify the single point failures in any system in the vessel which, if they were to occur, would cause loss of the position-keeping capability of the vessel, ” explains IMCA’s Technical Director, Jane Bugler. “The causes and consequences of any such failures should be noted and obvious corrective actions, which can be taken to avoid such failures, should be described in the final FMEA report.”
The FMEA should be a comprehensive systematic investigation that establishes the failure conditions of the DP system. Primarily, it is an analytical process that takes advantage of experience where possible. “For the FMEA to be useful, relevant and acceptable to all parties it should be performed by competent personnel, properly managed and be executed to a sufficient level of detail to demonstrate all requirements of this specification, ” adds Jane Bugler. “It needs to satisfy classification society and regulatory requirements, and should be suitable for use as a training reference for operators and maintenance staff of the vessel.
“It would be revisited as a result of changes made to the system during the life of the vessel and in the light of any information gathered at a later date that was not available at the time of the FMEA. Any changes to the FMEA should be addressed during the next DP annual trial, thus making the FMEA report a ‘living working document’.”

• IMCA is an international association with over 850 members in more than 60 countries representing offshore, marine and underwater engineering companies. IMCA has four technical divisions, covering marine/specialist vessel operations, offshore diving, hydrographic survey and remote systems and ROVs, plus geographic sections for the Asia-Pacific, Central & North America, Europe & Africa, Middle East & India and South America regions. As well as a core focus on safety, the environment, competence and training. IMCA seeks to promote its members’ common interests, to resolve industry-wide issues and to provide an authoritative voice for its members.
• IMCA publishes some 200 guidance notes and technical reports – many are available for free downloading by members and non-members alike. These have been developed over the years and are extensively distributed. They are a definition of what IMCA stands for, including widely recognised diving and ROV codes of practice, DP documentation, marine good practice guidance, the Common Marine Inspection Document (CMID) – now available electronically as e-CMID, safety recommendation, outline training syllabi and the IMCA competence scheme guidance. In addition to the range of printed guidance documents, IMCA also produces safety promotional materials, circulates information notes and distributes safety flashes.
