MV BLUEFIN QUALITY MANUAL - Australian Maritime College

Australian Maritime College
Students under instruction and involved in a practical training exercise showing how to use
the derrick in the working environment, are the responsibility of the lecturer running that
class. The lecturer must obtain permission from a member of the ship’s crew prior to using
the derrick and clearly demonstrate its operation to students before allowing them to use
the controls.
During such an exercise, the lecturer will be close to the operating controls at all times
should it be necessary to assume immediate, overall control.
Any personnel other than those detailed to assist in derrick operations, are to keep well
clear of the working area. The person in charge has authority to ‘STOP WORK’ and order
persons to ‘KEEP CLEAR’. Such an order can be transmitted using the public address
system to the main deck (the microphone is on the control console). Work is only to be
resumed when the area is safe.
Tag Line(s)
A tag line(s), of sufficient length that it may be passed from ship to shore, is to be attached
throughout the process of transferring loads to prevent it swinging and to assist in its
positioning.
Power supply
Only the ‘Stand by’ hydraulic pump may be used for derrick operation. NEVER use ‘Main’
hydraulics. The main supply runs off the main engines and generates too much power to
control the derrick in a safe and steady fashion.
Using the derrick at sea
Great care is to be exercised when using the derrick while the ship is at sea. Under no
circumstances should the equipment be used whilst the ship is rolling. The vessel’s
movement must be limited to the bare minimum necessary to maintain steerage only in a
following or head sea and swell. At no time is the load to be raised any higher than the
absolute minimum sufficient to move it to a new location. Tag lines MUST be attached
securely and attended constantly until the operation is complete.
Using the derrick to launch or retrieve the ship’s tender
The reader’s attention is drawn to the specific instructions and procedure “Ship’s Tender
Launch and Recovery” located in the Operational Safety and Training Manual prior to
attempting any boat/derrick exercise. There is a real potential for damage and danger.
Seek assistance from someone who has done this before.
