In-water Cleaning The physical removal of biofouling from a ship while in the water.
In-water Treatment Systems Treatments that are applied directly to the fouled area of the vessel to render biofouling organisms nonviable in situ, but which do not remove the organisms physically. Surface-treatments may include, but are not limited to, systems that apply heat, biocides or ultrasound to biofouled areas of the vessel.
Jurisdiction All the relevant states and territories of a nation.
Layup Vessels which have temporarily been taken out of service (e.g. due to lack of charter or cargo). ‘Hot Lay up’ and ‘Cold Lay up’ are two common techniques of laying up the vessels. During a Hot Lay-up, the vessel is out of service but can be mobilised into service at a short notice. Whereas in cold lay up, the vessel is moored or anchored at a safe place, awaiting newer employment / charter.
