All ships are exposed to the influence and wear of the ocean, causing structural components to wear down over time and require constant preventive and scheduled repair. This ensures that a vessel is in a state of constant service readiness. In order to ensure this serviceability, it is necessary to conduct certain inspections at certain periods throughout the year, including the underwater survey and assessment of necessary repairs. Underwater surveys (both scheduled and un scheduled) are necessary to the effective and safe manning of a vessel due the potential risks the industry entails. The underwater survey of the ship’s hull state is a procedure which is required for each ship irrespectively of her type and cargo-carrying capacity.
The underwater survey is necessary for estimation of the general and detailed technical state of the ships hull before docking, purchase or sale of the ship as well as a compulsory part of a package of measures approved by the Classification societies. In water survey of ships afloat Master Divers has the capability of inspecting vessels both in dock and afloat. In accordance with official rules and industry standards, the underwater inspection (survey) as well as estimation of state of the ships hull when the ship is afloat is possible only with special instruments and equipment by means of which the measurements should be carried out, this includes a video transmitting system, where images can be viewed in real time (CCTV or underwater television). Fault detection methods like this enables assessment of a ships structural integrity while the ship is afloat, without the necessity of docking.
Making it possible for management to carry out a qualitative examination of the hull shell plating and moreover to check its anode and cathodic protection and fasteners and state of plates in the shell plating in order to define availability and localization of dents, cracks or fractures. This also provides a means of inspecting the sea valve gratings and the propulsion/steering unit by measuring the bearings sag of the rudder blade stock and stern gear. Inspection afloat makes it easier to identify the possible risks and better to define the list of the forthcoming repair works. At Master Divers we see each vessel as an individual, each with her own history and fate; which is why every time the underwater survey is carried out, we take into account the specific individual traits and necessities of the vessel. In most cases, the ship’s underwater inspection is carried out under supervision of the Classification Society inspector, and the diving companies performing the inspection are pre-tested for competence in a required Classification society and have its recognition at the hands for performing the works as to surveying the ships. The approximate description of the list of arrangements carried out by divers during underwater inspection is as follows: As a rule, specialists-divers, equipped with special instruments and video-equipment according to the approved survey program, are dived into a required depth. Then those places and objects which should be checked are shown to an inspector.
The inspector observes the inspection and constantly sees the image on his screen, enabling him to adjust the divers’ work and direct their actions. All aspects of the underwater part of the hull, bottom and side openings, bilge keels, welded seams, riveted joints and many others are examined. The propellers are thoroughly examined, their state is estimated and availability or unavailability of cracks or corrosion on the surface of blades are defined. If necessary for discussion of the disputable matters, more detailed or repeated examination, all detected defects are captured by photography and video recording. The underwater inspection (survey) can also detect the hull dents which a specialist-diver measures by means of special meters, magnetic strips and other instruments. Sometimes the underwater inspection is accompanied by simultaneous repair works in the case if the defects can be eliminated at once afloat. Such partial and urgent repair helps to prolong the reliability of the ship’s operational characteristics and to decrease the emergency risks to a considerable extent.
Fundamental maintenance and performance requirements specified by a ship owner involves a clean hull and smooth propeller. Anti-fouling paints have been known to offer protection against marine growth which leads to reduced additional fuel requirements to maintain the same speed. The greater the time spent at sea, the less the anti-foulant effectiveness, and therefore, ship owners should intervene to arrest this process which in turn would reduce navigational expenses.
Throughout the years we have invested in the development of state of the are underwater hull cleaning equipment and now offer an international service that can give ships back their efficiency without the need for drydocking. This service is offered on a worldwide basis through a network of strategically located underwater hull cleaning stations across the globe. The unique design of our series of underwater hull cleaning units provides the efficiency and durability demanded by the harsh underwater environment. All systems are carefully constructed so that no damage will occur to those hull coatings which are suitable for underwater cleaning, while still completely removing all types of fouling. This restores a vessel’s performance to as close to its optimum condition as possible and offers shipowners considerable savings in fuel.
The three stages below illustrate the process of deterioration caused by marine growth on ships and other vessels:
Various anti-fouling layers on the ship’s hull over time decrease in effectiveness
Soft marine growth consisting of algae, slime and immature barnacles start to adhere to the plating and penetrate the protective anti-fouling coatings
Barnacles and tubeworms develop and attach themselves to the steel plating, causing permanent hull damage Hull cleaning Services Prevention In order to prevent and minimize this damage, an overall clean should be carried out at phase 2, requiring a rotary cleaning system using soft nylon bristles. Triton Diving Services with its specialized divers use twin brush hull cleaning machines which clean up to 800m²/hour.
