Sažetak
Maneuvering the ships during positioning in the oil fields and other specific locations using four anchors with winches (Four Point Mooring Ships) is considered a demanding and responsible job of the captain. Ships of this type are fitted with more than 1000 m of wire rope on every winch drum, and the work area, i.e. the seabed, involves quite a lot of various obstructions such as oil wells, underwater gas and oil pipelines, and the like. If the tasks are performed in the tropics, additional difficulties include volatile and changing meteorological and oceanographic conditions. Findings produced by statistical analyses show that these ships' anchors cause severe damage to underwater installations, amounting to millions of U.S. dollars. Experience and training of the master and the deck crew are exceptionally significant for damage prevention, particularly when anchors should be hoisted fast and the position left quickly due to impending bad weather. When carrying out these maneuvers, the master must act in accordance with the regulations of the oilfield concessionaire and has to be familiar with his ship's maneuverability and anchor system, in order to minimize the risk of damaging underwater installations. The basic objective of this paper is the analysis of complex procedures performed when handling anchors and maneuvering the ships of this type, and defining safety measures when carrying out these operations. Insights and findings produced by this research can be also used for education and training of deck officers and masters taking part in this kind of maritime venture.
