CHIRP’s comments CHIRP Comments Both the securing points and lifting points of a tender must Anchorage locations should continuously be assessed for be adequately designed to handle the deadweight and other proximity to known hazards, including under-keel clearance and reasonably foreseeable shock loading that might arise (eg potential grounding, safe swinging distance from other nearby failure of one of the other securing points). vessels, and holding ground capability in inclement weather. CHIRP could not determine why the previously reported Although vessels will generally anchor close to the shore defects had not been addressed by the vessel’s senior for their passengers’ convenience, vessels should be ready officers, but it is good practice for defect-reporting systems to to move to a deeper anchorage if the vessel’s safety cannot assign responsibility for rectifying a defect to a named officer, be assured. In this incident the vessel was anchored only 30 who should assess and prioritize resolution, and if necessary, meters from a lee shore. Given the expected weather forecast, take the equipment out of action until this is done. this was an unacceptable and unnecessary risk. Safety is everybody’s responsibility, and CHIRP Using two anchors when expecting bad weather can wonders why crew boarded a tender with known lifting help to control the vessel’s yaw but should be considered point issues?

Pre-departure checks (PDCs) included securing all M2282 hull openings. However, due to the hull and door shape, this opening could only be seen by leaning over the side. The shell door sensor was also sometimes faulty, giving inaccurate alarm and monitoring system readings. Lack of safety assessment Closing the shell door was a two-stage process: first, the ladder section, then the door, and these operations were often by the Master done by two crew members at different times. This contributed Initial report to the incident, as each crew member assumed the other Onboard a small motor yacht alongside the dock, someone had completed the task.

The captain directed that it be retrieved by sending someone down with scuba gear. When informed that CHIRP Comments this would require a permit to work, the captain insisted it was This report involves several critical factors contributing to not required. Despite concerns about the need for a permit or the safety issue. Firstly, a design flaw meant that it was some formal procedure, the captain dismissed the idea and difficult to see if the shell door was securely closed and requested proof of legislation that mandated a permit to work sealed. This was worsened by a faulty sensor for door for diving under the boat. When the suggestion to consult closure status, known for unreliability yet not maintained the Code of Safe Working Practices (COSWP) was made, the and thus compromising safety alarms. CHIRP has frequently captain insisted on quickly retrieving it without any permit. highlighted sensor issues, especially in exposed areas. Additionally, time pressure to complete tasks quickly led CHIRP Comments to shortcuts and assumptions, with crew members prioritising In this situation, the appropriate steps involve consulting speed over thoroughness.
