The Swedish Club shares lessons learned from a loss of anchor incident, which took place in heavy weather. The anchor and chain were lost and the vessel was not allowed to continue its journey until the anchor and chain had been replaced.
The incident
The vessel was waiting for its berth to become available, and decided to anchor. A preanchor briefing took place on the bridge where the number of shackles to be used was discussed and what different tasks the crew had during the anchoring operation.
