The Code of Safe Practice for Ships Carrying Timber Deck Cargoes (TDC Code) is the International Maritime Organization (IMO) standard for the safe carriage of timber deck cargoes.
[5] This includes logs and sawn timber, either loose or packaged.
It also includes guidance for ship securing manuals and checklists for safe operations.
[1] Because of the increased weight of timber cargoes on a deck, the Code requires the ship's stability to be calculated according to a set list of criteria and guidance.
[4] The 2011 update to the Code include the addition of loop lashing as an optional shipboard practice compared with top-over lashing for securing timber deck cargoes.
