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.
