2. HEAVY LIFT CARGO
What is heavy lift cargo?
Heavy lift cargo is classified as indivisible items
weighing over a ton up to over a thousand
tons and has widths and/or heights that
exceed 100 meters.
3. Examples of heavy lift cargoes
generators, turbines, reactors,
boilers, towers, casting, heaters,
presses, locomotives, boats,
satellites, military personnel and
equipment.
4. REQUIRED INFORMATION
Before loading heavy lift cargo I will try to collect
information about such a cargo including:
1. What type of cargo.
2. The weight of cargo.
3. Dimensions and size of the cargo.
4. Whether cargo will be loaded by ship/shore's lifting
gear.
5. When the cargo is arriving.
6. Destination of cargo.
7. Where the cargo will be loaded as per shipper's
instruction.
8. Include the heavy lift in cargo plan, considering all
the aspects of cargo planning
5. RIGGING OF HEAVY LIFT GEAR
1. All gears associated with lifting such as runners, guy
pendants, tackles, blocks etc, to be examined carefully.
2. Lifting gears and associated equipments to be
greased and renewed as necessary.
3. All other riggings cleared.
6. RIGGING OF HEAVY LIFT
GEAR(CONT’D)
4. Rig wires, blocks etc as per rigging plan.
5. Rig Preventers and backstays as per the plan.
6. Topping lift in good condition and securely
shackled.
7. Winches should be in double gear.
8. Derrick unclamped from mast.
9. Set tight preventer guys.
10. Rig extra stays if required
11.Once clamp removed, take weight on
messenger and slowly lower the derrick.
7. PRECAUTIONS PRIOR TO LIFTING THE
CARGO
1. Check vessel’s stability.
2. Maximum possible loss of GM in the operation to be
calculated.
3. Maximum possible list and trim during operation to be
calculated.
4. Free surface effects to be considered.
5. All tanks should be pressed up or empty to avoid free
surface effect.
6. Vessel to be even keel and upright as far as practicable.
7. Rig fenders.
8. Cast off any barge.
9. Test the SWL of the lifting gear and associated
equipments, it must be above the weight to be lifted.
8. PRECAUTIONS PRIOR TO LIFTING THE
CARGO(CONT’D)
10. Check load density of the hatch/deck area
the load being loaded.
11. Load density must not exceed the value
given in stability booklet.
12. Distribute load on deck using dunnage.
13. Rails removed.
14. Barges cast off.
15. Unnecessary personnel removed.
16.Lashing arrangement is sufficient. Extra
lashing points may be welded.
9. PRECAUTIONS DURING LIFTING
1. Inform E/Room and galley.
2. Inform all relevant personnel.
3. Ensure fore and aft moorings are taut and tended.
4. Use steadying lines (swing preventers).
5. Competent winch man.
6. Communication signals understood. Standard signals
as per COSWP to be used.
7. Only one competent person to signal the whole
operation.
8. Whole operation to be supervised by a responsible
officer.
9. Raise gangway.
10. The derrick to be plumbed over the weight.
10. PRECAUTIONS DURING
LIFTING(CONT’D)
11. Take weight slowly.
12. Lift the load slowly, swing in the correct position and load on
the appropriate position.
13. Control swing by steadying stays.
14.Consider emergency action if vessel develops heavy list (more
than calculated) during the operation.
15. Take proper lashing, considering heavy weather on the voyage.
16. Best place to load
17. Best place is where extra strengthening is provided by:
18. Longitudinal, plate floors.
19. Solid floors or transverses.
20.Examples: along longitudinal centre girder, lower hold abaft
machinery space.
21.Load density not to be exceeded.
22.In the hatch, in preference to on deck because of larger GM.
11. PRECAUTIONS AFTER LOADING THE
CARGO ON BOARD
1. Take proper lashing considering heavy
weather on the voyage.
2. Check the lashings daily and tighten any
loose wires when found during inspection.
