Open hatch general cargo

Open Hatch General Cargo (OHGC) is a vessel-type designed to transport forestry products, bulk, unitized cargoes, project cargoes and containers. The vessel is typically fitted with two Gantry cranes for self loading and unloading, with a typical SWL (safe working load) between 30 and 80 tons. Different equipment is connected to the gantry crane depending on cargo type as vacuum clamps for paper, unihook for unitised cargo, container frame and grab for bulk cargoes. Cargo holds are box shaped to fit containers and some holds can be equipped with tweendecks to improve flexibility of cargo mixture in same hold. Holds are typically equipped with dehumidifier for sensitive cargo. Hatch covers for holds are opened and closed by mean of gantry crane. Space on those hatch covers can also be used to carry containers, lumber or project cargoes.
