What is IMO Code of Safe Practice for Ships Carrying Timber Deck Cargo?

Should be compiled in conjunction with M.S.Deck Cargo Regulations,  Additional requirements laid down by this code :

• Lifeline of wire rope with stretching device near vessel’s C/L in addition to walkway
• Linear interpolation for intermediate height
• Cargo height 6 m & above  :      5 m
• Cargo height 4 m & below  :      0 m
• Lashing intervals in relation with cargo height
• Stability information pertaining to deck cargo- available to master
• Master must verify vessel’s stability for worst service condition –  
• increase deck weight due to :
  • water absorption
  • ice accretion
  • variable in consumables- fuel, FW

Packaged timber :

• The cargo is stacked rather than stowed which leads to cargo  movement, slack lashings and subsequent damage.
• Random lengths are not to be stowed on deck unless :
  1. They can be stowed compactly
  2. They are not stowed on exposed surfaces
• Bonding should be strong to avoid disintegration.
• Deck surfaces to be made level with timber before loading.
• Dunnage between layers to bind the stow and keep it level.
• Stow and secure other timber cargoes independently
• Generally athwartship stowage avoided, particularly in adjacent and two top layers.
• Rounded angle irons, at least one foot long should spread the load of  the lashings at the upper corners of the stow.
