On May 10, 2018, Amix Marine Projects completed an anchor recovery job near Nanaimo Harbour.
The crew onboard Amix’s crane barge, the Arctic Tuk, and its accompanying tug, the Arctic Taglu, worked late into the night retreving a ships’ anchor that had broken free and sunk to the sea floor.
The first challenge of this job was finding the lost chain. The anchor was lost in a 4,800 foot diameter surface area outside Nanaimo Harbour, in 95 meters of water. The anchor was located using video feed from a submersible ROV (remotely operated vehicle).
Amix then needed to find a way to hook onto the anchor and bring it up. The crew fabricated a grapple that the Arctic Taglu dragged along the ocean floor. Once the the chain was hooked, the ROV went down to confirm with live video footage. Using the tug’s winch, the grapple was brought up and then transferred to the barge’s crane. With patience and perseverance, the chain and anchor were recovered in a safe and successful operation.
The anchor and chain combined weighted in at 56.5 MT (125,000 lbs).
