What are Safety measures for vessel carrying Timber ?

1. MPA OF SINGAPORE MARINE CIRCULAR TO SHIPOWNERS NO.9 OF 1988.
2. Recently a timber carrier was lost with all hands on board in rough weather in the South China Sea. Investigations revealed that the vessel had sustained damage to one of her hatch covers (while loading logs) and that this could have been a contributory cause of the casualty. Investigations done by other authorities into the losses of timber laden vessels also confirm that these vessels are more susceptible to structural damage during cargo operations which could result in cracks in the hull plating. These cracks may not be discernible at the loading port or in calm weather. However, in rough seas, these cracks become apparent when the holds become flooded. If no preventive action is taken then, the vessel could develop a list and possibly sink.
3. Masters of vessels engaged in the carriage of timber are advised to take the following measures. They should:
   • ensure that the bilge wells are cleaned every voyage and the bilge pumping arrangements are tested before the commencement of loading;
   • supervise the loading operations to prevent any damage to ship’s hull, frame or hatch covers caused by careless loading;
   • examine the hull plates externally at regular intervals to check for any traces of cracks particularly in the number 1 and 2 holds and if any cracks are noticed they should be repaired before leaving the port;
   • ensure that all the deck openings are securely closed and battened down;
   • ensure that ventilators and air pipes are effectively protected from damage by the cargo;
   • sound the holds frequently especially in head sea conditions;
   • ensure that the vessel has adequate GM during the voyage;
   • check the vessel’s list frequently during the voyage; and i. deviate to a port of refuge if it is discovered that the vessel has taken in water in her hold(s).

PART 1 – Requirements which apply to ALL deck cargoes

• Avoid excessive loading
• Adequate stability at all stages of the voyage especially with regards to :-
• Vertical distribution of the deck cargo.
• Wind moments produced by strong winds.
• Loss of bottom weight- consumption of stores, fuel, fresh water.
• Increase in weight – water absorption by deck cargo, icing etc.

Ensure the proper protection of water tightness ventilators, air pipes and the of lower compartments
