Heavy Lift

Question 1

Outline the procedures and precautions that must be taken when a ship is to load a heay lift.

Answer 1

Before commencing cargo operations the following factors need to be considered:

The ship:

• The ships lifting equipment (Is the SWL sufficient for the proposed load? Are all SWL and load test certificates up to date? Is there sufficient loading equipment?)
• Stability (What will be the vessels maximum angle of heel? Does the vessel have sufficient stability throughout the intended voyage?)
• Stowage location (Is the deck strong enough? Are their sufficient lashing point? Is the stowage position sheltered enough to protect the cargo during the intended voyage? What is the maximum loading allowed per square metre?)
• Operational plan (A detailed operational plan should be produced)
• Communications (There must be adequate communications between the ships staff and any shore employees engaged in the operation)

The cargo:

• What is the cargo?
• What is its weight?
• Does it have sufficient lifting points?
• Where is the centre of gravity of the cargo?

During the cargo operations the following points to be considered:

• Before commencing operations the vessel must be as near to upright as possible.
• The maximum angle of heel must be known.
• Where possible ensure that there is no slack tanks.
• If necessary sufficient dunnage should be laid to protect the ship, and spread the load.
• Slings of the correct length and SWL should be available.
• Are the lifting points satisfactory.
• Ensure steadying lines are attached if required.
• Some vessels may require additional ‘Mast Stays’ are rigged.
• When lifting the load ensure that the weight is taken slowly.
• The vessels moorings should be attended throughout the lifting operation.
• The accommodation ladder or gangway should also be attended.
• Ensure the ship’s side rails are removed.
• Make sure there is adequate power on deck for the cargo operation.

Question 2

State the document that must be checked to ensure that the lifting gear has been adequately maintained and inspected.

Answer 2

The document that must be checked to ensure that the lifting gear has been adequately maintained and inspected is the Chain Register.
