This Code apply to all ships of 24 metres or more in length, carrying a timber deck cargo.
The Code provides:
- Practices for safe transportation;
- Methodologies for safe stowage and securing;
- Design principles for securing systems;
- Guidance for developing procedures and instructions to be included in ships’ cargo securing manuals on safe stowage and securing; and
- Sample checklists for safe stowage and securing.
Purpose of this code:-
The purpose of the Code is to ensure that timber deck cargoes are loaded, stowed and secured to prevent, as far as practicable, throughout the voyage, damage or hazard to the ship and persons on board as well as loss of cargo overboard.
In other way we can explain purpose of the code as:
The purpose of this Code is to assist:
- Shipowners, charterers, operating companies and ships’ crew for the safe carriage of timber deck cargoes.
- Port industries, shippers and pre-packaging organizations, which are involved in preparation, loading, and stowing of timber deck cargoes; and
Administrations, manufacturers and designers of ships and equipment associated with the carriage of timber deck cargoes and those developing cargo securing manuals, in the carriage of timber deck cargoes
