Frequent underwater hull cleaning extends the life of your bottom paint, by removing the algae slime layer before hard growth can attach and dig into the bottom paint.  A major cost of operating a boat is the cost of fuel. Any reduction in fuel consumption will result in a direct and proportional reduction in operating costs. Since up to 70% of a ship’s propulsive energy is needed to overcome hydrodynamic resistance (friction), keeping the hull and propeller surfaces smooth will minimize waste and improve the speed and/or distance to be gained from burning a barrel of fuel.

Underwater cleaning has other economic advantages besides those associated with propulsion efficiency. Unclogging fouled suction grates improves the flow of water to internal machinery and reduces pump wear. Cleaning the hull regularly prevents biofouling buildup, thereby lengthening the effective life of the anti-foulant coating and sustaining the anti-corrosive coating system for longer dry-dock intervals.

Salvage and Reclamation of Lost Vessels

Marine salvage is the process of recovering a ship, its cargo, or other property after a shipwreck. Salvage encompasses towing, refloating a sunken or grounded vessel, or patching or repairing a ship. Today the protection of the environment from cargoes such as oil or other contaminants is often considered a high priority.

EXTENSIVE STUDIES carried out by the British Ship Research Association (BSRA) have shown that a power loss of up to 6% can result from a roughened propeller. Although it is well known that hull roughness causes serious energy loss, it is perhaps surprising that, according to the BSRA research, the propeller with its small surface area, can generate energy losses amounting to half that of the hull.

Poor hull condition has often been cited as the cause of falloff in performance with time in service, although in practice a significant contribution to the reduction in performance may well have been due to propeller roughness. Admittedly, in absolute terms propeller roughness is less important than hull roughness, but in terms of energy loss per unit area, propeller roughness is significantly more important. In economic terms, high standards of propeller maintenance are, therefore, more cost-effective compared with hull maintenance for most ship types and this will be demonstrated in the following set of case studies.

An alternative simplified method of assessing the propeller surface condition is to use a set of replica gauges. The Rubert propeller replica gauges presents six different surface replicas ranging from smooth (A) to very poor (F). One of the principal advantages of using a set of replica gauges is that the propeller surface condition may be assessed by divers when the vessel is in water, therefore allowing more frequent inspections than the normal two or three yearly dry-docking intervals.

Inspections of Docks, Piers, and Underwater Structures including Cleaning and Repair

Levels of Underwater Inspection

Standard levels of inspection originated in the U.S. Navy. Three levels of inspection have been established as the result of the process through time. These are:

    Level I -- Consists of a simple visual or tactile (by feel) inspection, without the aid of tools or measuring devices. It is usually employed to gain an overview of the structure and will precede or verify the need for a more detailed Level II or III inspection.
    Level II -- A detailed inspection which involves physically cleaning or removing growth from portions of the structure. In this way, hidden damage may be detected and assessed for severity. This level is usually performed on at least a portion of a structure, supplementing a Level I.
    Level III -- A highly detailed inspection of an important structure which is warranted if extensive repair or replacement is being considered. This level requires extensive cleaning, detailed measurements, and testing techniques that may be destructive or non-destructive in nature.
