The Nautical Institute stories of a dragging anchor incident ensuing within the collision of vessels.
What occurred?
Two bulk carriers had been at anchor awaiting berthing directions, a secure distance away from one another. Excessive winds had been forecast within the space for later that night time, however the crew on one of many bulk carriers was unaware of this reality. When the wind picked up, the vessel started yawing because it was hit by robust gusts, inflicting its dragging anchor alarm to sound. The OOW seen their vessel beginning to drift in direction of the second bulk provider and known as the Grasp. An additional two shackles had been shortly paid out on the starboard anchor chain. The crew additionally tried to deploy the port anchor, however was unable to take action.
In the meantime the second vessel had been knowledgeable of the drifting and paid out an extra 11 shackles in an try so as to add extra space between the 2 ships. The primary vessel’s crew ultimately managed to deploy the port anchor and tried to make use of the primary engine to manoeuvre away from the second ship, however the two bulk carriers collided, main to break to each vessels.
Why did it occur?
The crew of the primary bulk provider had not thought of the affect of excessive winds or heavy climate on their anchoring choices.
The crew didn’t accumulate the native climate forecast from the VHF radio, climate fax or MF broadcast.
Neither had the crew obtained up-to-date climate data for the native authorities.
This lack of preparation and knowledge meant the crew of the primary vessel was unable to mitigate towards the results of heavy wind and powerful gusts on their ship in time to forestall severe yawing, drifting and collision.
What classes had been realized?
Climate forecasts are a key a part of situational consciousness throughout each the passage strategy planning stage and on the day itself whereas at sea or throughout anchoring.
The Grasp and OOW should prioritise climate consciousness whereas at anchor and heed any and all warnings in loads of time to take motion wherever potential.
Regardless of a vessel having a powerful engine and anchor, restricted areas in some anchorages can severely restrict choices throughout robust winds and heavy climate. A ship is safer at sea than at anchor in some conditions.
