Ship underwater cleaning guide
1 Scope
This standard stipulates the working process of underwater cleaning of marine vessels, including the biological classification of hull underwater pollution, cleaning and inspecting assessment, and clearing
Washing procedures, data collection, hull surface cleaning and acceptance criteria.
This standard is applicable to the underwater inspection and cleaning and acceptance of marine vessels by marine underwater cleaning enterprises, and can be used to guide oil drilling.
Underwater inspection, cleaning and acceptance of equipment and facilities such as Taiwan, bridge terminals and nuclear power plants.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Marine pollution organism fouling
Marine life attached to some underwater equipment and facilities.
Note. Contaminated organisms are divided into three types. software, hardware and complex.
2.2
Soft-contaminated organism softfouling
Sludge and seaweed attached to equipment and facilities in the water.
2.3
Sludge slime
Marine microorganisms are attached to the primary stage of the hull.
Note. The first step of the pollution process is the formation of sludge, immersed in the surface of the object in the seawater, will quickly form a layer of sludge containing bacteria, fungi, original
Raw animals and seaweed. The surface of the wet object will adhere to bacteria and polluting organisms within 1 hour, forming a smooth sludge layer on the surface of the object.
2.4
Seaweed and other algae grassandotherfouling
A single plant or a long series of simple plants attached to the reef, various parts of the hull and other solid structures in the water.
2.5
Hard-contaminated organism hardfouling
Contaminated organisms such as barnacles, tubular worms and calcium carbonate deposits.
2.6
Barnacles barnacles
A cluster of grayish-white, marine organisms with a calcareous outer shell attached to the object.
Note. There is usually a conical hard shell with a jagged top.
2.7
Tubular worm tubeworms
Usually one of the upper ends formed along the hull is a red meat head and the lower end is a long, straight white tubular creature.
2.8
Calcium carbonate deposits calcareousdeposits
It is deposited from the exposed metal surface of magnesium and calcium carbonate in water.
Note. There is a strong adhesion, especially on the bare metal surface of the propeller, it is easy to form a uniform calcium carbonate deposit.
