REPLACING A LOST ANCHOR ON A CONTAINER SHIP

ALATAS’ SERVICEMERCHANT SHIPPING
LOCATION  ASIA / SINGAPORE /
EQUIPMENT  SHIPS ANCHOR

BACKGROUND:

The vessel lost its anchor when the shank ruptured, causing the anchor crown, along with its arms and flukes, to sink into the sea. An urgent replacement was necessary.

ALATAS SOLUTION:

ALATAS specializes in anchor replacement repairs, typically conducting them at Singapore Anchorage during bunkering, with a repair duration of less than 8 hours. Responding to the owner’s request, ALATAS assembled a repair team comprising welders and fitters, along with a flat-top barge, to deliver the new anchor to the vessel at Singapore Anchorage. The team then proceeded to remove the old anchor’s swivel and ‘D’ shackle from the damaged shank and affix them to the new anchor, connecting it to the existing anchor chain. All operations were performed on the barge positioned alongside the vessel’s bow.

JOB SCOPE:

  • Obtain a hot work permit and appoint a hot work assessor.
  • Secure a flat-top barge, load the new anchor onto it, and position it alongside the vessel’s bow.
  • Lower the damaged anchor shank, swivel, and chain onto the barge beside the new anchor.
  • Utilize an oxy-acetylene flame cutter to remove the old shackle pin, as it cannot be extracted by any other means.
  • Attach the new shackle to both the new anchor and the anchor chain.
  • Insert the conical pin to secure the shackle pin in place.
  • Weld the conical pin and seal it with lead.
