PreambleThis is a work about a maritime accident that occurred in the North Sea in early autumn 2007. In a chain of reactions, the accident cost the lives of three people ; whereas everything could have been prevented and normal functioning could have taken place without me writing a mission on this subject six and a half years later. The abbreviation ERRV Viking Island was, and still is (2014-01-24), a UK registered ship in the ERRV class. ERRV stands for Emergency Rescue and Recovery Vessel. ERRV vessels are most often on standby alongside an offshore installation or "community" of installations whose primary task is to rescue/recover people from the water and provide first aid. medical. During accidents, ERRV vessels act as an OSC (On-Scene Coordinator) and can also act as an additional radio station if it is not possible to continue broadcasting signals from the offshore installation. Additionally, the missions of ERRV vessels include the protection of the installation, and therefore the surveillance of the security zone around the installation. The security zone is a five hundred meter circular area that vessels are not permitted to enter without permission from the installation. If a vessel heads toward the facility without authorization, the ERRV vessel will act as a guard and make efforts to stop the threat. Ship Working Hours The Viking Islay is just one of these ship types, with a waiting time of normally 28 hours. days alongside the ENSCO 92 platform, on the Amethyst gas field, 22 nautical miles off the coast of East Yorkshire, in the British sector of the North Sea. When the Viking Islay was not in her waiting position (for example, sometimes during a crew change), a replacement had taken her place. Together they cover...... the middle of a paper...... and call for help. Two crew members who heard and responded to the alarm were the 1st officer and the 2nd officer who, with the AB, ran to the command post. At the command post, the three people looked into the compartment and saw two bodies. lying on the bottom, unconscious. They all returned to the accommodation and, together with the cook, found and gathered rescue equipment, a BA (breathing apparatus) and an EEBD (emergency escape breathing apparatus). At 11:07, the ship's general alarm was sounded by the captain, causing the rest of the crew to assemble at the designated assembly point. The captain also contacted the ENSCO 92 platform to inform them of the accident. ENSCO 92 made preparations and assembled its own crew to assist the Viking Islay. Together, the crew assembled at the rear assembly station headed towards the accident site..
