AI-SHIPPING (Manager of the branches PSOMAKARA & GAMSRO) provides underwater hull cleaning services, in multiple ports worldwide such us (In Greece – Piraeus, Kali Limenes, Chios, Kalamata, Neapoli, Lavrio, in Togo – Lome, in Cyprus – Limassol, Larnaca, and many more globally) saving money and time away from the dry dock using experienced diving teams. The rich activity of the underwater (uw) ship repairs company AI-SHIPPING (Manager of the branches PSOMAKARA & GAMSRO) is a glowing unique example of a speedy and healthy development in the maritime sector. Our Company has experienced and well trained diving staff in underwater repair and underwater maintenance of ship hulls. Moreover, we provide a whole range of wet services that ships require.

The main objective of AI-SHIPPING (Manager of the branches PSOMAKARA & GAMSRO), is the continuous enhancement and development of money saving choices that it ensures its customers. owards this direction, the most effective solution in saving money is the underwater hull cleaning. “Clean ship’s Hull means, reduction of fuel consumption, reduction of CO2 emissions, increase of ships speed.” “Fouled ship hulls increase the overall cost, causing increased fuel consumption and the emission of gaseous pollutants. The engines are strained as well as the propulsion system, the ship slows down.

One of the biggest problems facing the world shipping is fouled ships hulls. 1746 different species of marine organisms have been counted up, which are attached to submerged surfaces. Like shellfish, seaweed, sea moss and hydroids, which clog the underwater intakes, covering antifouling paint and creating a thick layer on the ship’s hull which in time destroys and affects its “good” function. Shellfish such as oysters and mussels, release millions of young bivalves in the water, which move with the help of the ocean currents. The young bivalves to enable to feed themselves adhere to static objects, which attract various species of algae. Ships that are anchored are ideal for the growth of these microorganisms. Typically, these are reduced when the ship is at sail, except for some that are very durable, such as the Brown Weed, which remain on the hull even when the ship is developing rapidly.

The outcome of fouled hulls is the increase of abrasion resistance of the ship. The increased abrasion leads to speed reduction. Coating with 1mm thickness increases the abrasion by 80% thereby reducing the speed by 15% (Townsin 1987; Lui et al, 1977). So in order to maintain the same speed greater fuel consumption is required, thereby increasing the cost and the emission of gaseous pollutants. Depending on the type of vessel, fuel can make up about 50% of the operating cost of a ship. It is estimated that the fuel consumption increases 6% for each 100mm increase of speed. The increase in weight of the hull from the fouling has the effect of reducing the hydrodynamic behavior of the vessel, since it lowers the center of gravity of the vessel, therefore affecting its maneuverability.

The Brush Kart System consists of a steering wheel and a speed control valve which is adjusted by the diver. All our divers have undergone many hours on the job training on our own vessels and when they master the usage of the Brush Kart System they are sent to customers’ vessels. All our u/w hull cleaning systems are constructed by strict specifications so no damage will occur to hull coatings.
