- The increased weight of the timber deck cargo due to:
- absorption of water, and;
- ice accretion if applicable;
- Variations in consumables (such as fuel consumption from tanks low down in the ship);
- The free surface effects of liquids in tanks, and;
- Weight of water trapped in broken spaces within the timber deck cargo and especially logs.
- Ships carrying timber deck cargoes should operate, as far as possible, with a margin of safety with respect to metacentric height (GM), however the metacentric height should preferably not exceed 3% of the breadth of the ship in order to prevent excessive accelerations in rolling that would cause large racking stresses and high stresses on cargo lashings which might result in cargo loss or shift.
There are few mistakes.
Point no 1- it should be 0.08m.
Point no 3 – It should be 0.25m
