The deckhand was able to raise the rescue boat smoothly. The deckhand began retrieving the rescue boat from the water using the davit while the first engineer and the technician stood by and observed.įrom their positions on deck 6, the deckhand and the first engineer could see the rescue boat as it was being raised however, they could not see how the hook and the lifting shackle were positioned. The sky was clear, but it was dark.Īt approximately 2340, after the technician had finished charging up the nitrogen, the first engineer came up to deck 6 at the technician’s request to witness the testing and acknowledge the completion of the defect repair. There was a northerly wind of 1 to 3 knots. This process took approximately 20 minutes.ĭuring this time, the sea state was calm without any swell. The uncrewed rescue boat remained floating in the water, with the fall slack and the lifting shackle and the hook resting on top of the fuel tank, while the technician charged the hydraulic accumulator with nitrogen. To allow the technician to access the accumulator chamber, the deckhand lowered the rescue boat to the water and slackened the fall by approximately 75 cm to 100 cm, then raised the davit back to its maximum height. In addition, 4 night-shift engineers and an engine room assistant were on board, performing duties in the engine room.Īs troubleshooting continued, the technician explained to the deckhand that he planned to charge the hydraulic accumulator with nitrogen. A deckhand remained on board to assist the technician. While the vessel was docked, either at Tsawwassen or Swartz Bay in between sailings, the technician, positioned on deck 6, lowered and raised the rescue boat several times with assistance from crew members to test the intermittent jerking defect and determine its source.ĭuring this time, the technician was unable to identify the source of the problem and decided to remain on the vessel after it shut down for the night to continue troubleshooting. On 19 June 2018, at about 1645, Footnote 1 an original-equipment manufacturer service technician for the davits on the Spirit of Vancouver Island boarded the ferry in Tsawwassen, British Columbia, to respond to a service call about intermittent jerking of the rescue boat davit. ![]()
