What are the types of Dunnages?
Types of dunnages are:
FLOOR DUNNAGE
This is mainly used in general cargo ships, to lift the cargo off the tank top. This prevent cargo damage from sweat or moisture running off from other cargo.Floor Dunnage is laid crosswise and the direction depends on the design of the vessel.
LATERAL DUNNAGE
This usually takes the place of a spar ceiling on a general cargo vessel. These are wooden beams securely connected to the side of the cargo hold. It prevents contact of the cargo with the ship’s side and so prevent cargo damage due to sweat.
INTERLAYER DUNNAGE
This separates cargoes from each other, either for the protection of an underlying cargo from contamination by a top cargo or the segregation of individual batches of cargo.
TOP DUNNAGE
This generally protects the cargo from contamination damage from water, hydraulic oil etc dripping from wet decks. Top Dunnage must also allow some air circulation and evaporation especially for hygroscopic cargoes.
