Ships hulls can be fouled with sea debris of various forms. Fouling involves building up of live sea organisms such as algae, barnacles and crustaceans. Fouling can also be from oil slicks. These fouling on the hulls causes the vessel to slow down and consume more fuel and in some cases not allowed to sail until certain actions have been taken. Fouling can be very severe in vessels that arent been sailing for a while or otherwise they have been laid up. Tropical waters causes more fouling compared to the temperate waters.
Pricing for hull cleaning depends on the length and depth of the vessel's hull. The maximum depth we dive for hull cleaning is 18 meters. Prices are also dependent on the amount of fouling. More than 2 cm of barnacle buildup will require more time and resources to clean.
