DYNAMIC POSITIONING OF OFFSHORE ANCHOR HANDLING TUG SUPPLY (AHTS) VESSELS (UT 788 CD Project)

Each vessel exposed to the forces of wind, waves and changes in sea level due to tidal streams and forces caused by the propulsion system, changes its position and heading. The basic function of the dynamic positioning system is to maintain the vessel's position and heading. This article analyses the use of the FMEA (Failure Modes and Effects Analysis) of dynamic positioning system of off-shore vessels which includes analysis of all subsystems connected to dynamic positioning (production and distribution subsystem of electrical power, automatics, propulsion and controller subsystems)[1]. Specifically, it is dealing with the dynamic positioning of the vessel UT 788 CD for deep anchoring, towing and platform supply, analysed in two operational modes: diesel electrical and conventional mode. According to the FMEA, the UT 788 CD vessel has met all the DP 2 class requirements for operating within the foreseeable volume in accordance with the IMO classification.
