MAJOR SAFETY CONCERN
The cover plates for anchor hawse pipes have been secured.
The spirling pipe cover plates are in place and cemented.
All ventilator openings on the various decks have been secured.
SECTION 11.2
Check the following after departure and during the heavy weather:
Check the period of roll and ensure the vessel’s GM (fluid) is as planned for the
voyage and is safe.
Take rounds once a watch and ensure all cargo lashing is intact.
All the lashing on deck, in accommodation, in engine room, stores and in galley
is intact.
All external openings from the cargo decks are secured.
Ensure all the items mentioned in the first paragraph regarding the checks before
departure are still valid.
11.2.5 A large windage area
As we have understood, that these vessel have low sinkage and with large cargo
capacity above the load line cargo capacity. This in turn results into a large windage area.
A large windage area makes these vessels, difficult to handle them in light breeze also,
particularly when the engines are not running.
These vessels behave like kites.
Details of calculations and effect of wind on these vessels is explained in section
8.20.
11.2.6 Increasing cargo capacity with increasing height of cargo deck
In general higher the height of the cargo decks from keel higher the cargo capacity.
Now you, check the vessel’s stowage plan, see picture No 1 and 2. See lower is the deck
lower is the cargo carrying capacity; and higher the deck, higher the cargo carrying
capacity. It is just reverse of other type of ships.
This also decreases the metacentric height of the vessel.
11.2.7 No centre line bulkhead in the cargo spaces
These types of vessels are also not fitted with any centerline division in the cargo spaces.
The cargo holds width is same as the beam of the vessel. Cargo holds extend from ship
side to shipside. Imagine now in the case of flooding of the vessel, a very large Free
Surface Effect will be generated. The originally with low metacentric height is bound to
loose stability and capsize and some time sink.
A very little time is with the ship staff to handle emergency.
11.2.8 Cargo Cost
Cargo is expensive cargo. Some times the cost of 2528 cargo units may be more than,
US $ 26 million. It is a large sum of money. So expensive cargo and so delicate in nature
has to be handle with extreme sensitivity. A few minor scratches on 20 new Mercedes
Benz or BMW cars may cause a cargo claim to US $ 200000.
Needless to say extreme care should be taken of these cars while they are on board.
11.2.9 Flammable fuel in the cargo and fire fighting.
Highly flammable gasoline or diesel is always present in the cargo. Also there is
flammable upholstery and other items used in the car. This makes the cargo, extremely
flammable in nature. During the cargo operation, fire hazards such as jump starting of car
