  • .5 stowage factor of the cargo;

  • .6 racking strength for packaged cargo;

  • .7 type of cover of packages and whether non-slip type; and

  • .8 relevant coefficients of friction including covers of sawn wooden packages if applicable.

  A.1.2 A confirmation on when the deck cargo will be ready for loading should be received.

  • .2 weight per m2;

  • .3 required amount of water ballast; and

  • .4 displacement, draught, trim and stability at departure and arrival.

  A.1.4 The stability should be within required limits during the entire voyage.

  A.1.5 When undertaking stability calculations, variation in displacement, centre of gravity and free surface moments due to the following factors should be considered:

  • .1 absorption of water in timber carried as timber deck cargo according to special instruction, see annex c;

  • .2 ice accretion, if applicable;

  • .3 variations in consumables; and

  • .4 ballast water exchange operations, in accordance with approved procedures.

  A.1.6 Proper instructions for ballast water exchange operations, if applicable for the intended voyage, should be available in the Ballast Water Management Plan.

  A.1.7 A lashing plan according to the ship's Cargo Securing Manual (CSM) should be prepared and the following calculated:

  • .1 weight and height of stows per hatch;

  • .2 number of sections in longitudinal direction per hatch;

  • .3 required number of pieces of lashing equipment; and

  • .4 required number of uprights, if applicable.

  A.1.8 The certificates for the lashing equipment should be available in the ship's Cargo Securing Manual.

  A.1.9 When the initial stability calculations and lashing plan have been satisfactorily completed, the maximum cargo intake should be confirmed.

  A.1.10 Pre-load, loading and pre-lashing plans should be distributed to all involved parties (i.e. supercargo, stevedores, agent, etc.).

  A.1.11 Weather report for loading period and forecasted weather for the sea voyage should be checked.

  A.1.12 It should be confirmed that the stevedoring company is aware of the ship's specific requirements regarding stowage and securing of timber deck cargoes.
