The UK Ministry of Defence recently announced that they are going to use ultrasonic anti fouling technology to help maintain the performance of three of its LCVP landing craft, the Australian Customs & Border Protection Service also installed ultrasonic anti fouling equipment on one of its patrol vessels. Several companies producing equipment using the same basic system of transducers attached inside the hull. These vibrations create a strong surface cleaning effect. Algae and slime is broken down and it is the absence of this preliminary surface that prevents marine growth of barnacles, weed etc: all hull materials except wood are suitable for this system. Hull openings such as water jets and tunnel thrusters and appendages e.g. pods and stern drives are also protected. Examples of vessel types for which this system is advertised are trawlers, ferries, tugs, barges and recreational power and sail.

This June the Finnish based Eniram company from Helsinki, was selected as a finalist of an award for emerging European technology companies Eniram provide a number of products for on board and ashore monitoring of ship performance offering real time solutions. A product gaining wider acceptance for owners and operators of cruise ships, large freight vessels and tankers is their Dynamic Trimming Assistant (DTA). A number of data sensors, with software analyzing the ship’s trim, helps vessel crews optimize trim at all times, by presenting the solution in an easy to understand graphical display. DTA does this by balancing inter related variables such as minimizing water resistance, decreasing fuel consumption, use of stabilizers and reducing emissions. External items such as waves, wind and speed are also included in the analysis. In practice, this means startling savings may be achieved. Several fleet operators are using DTA including Royal Caribbean Lines and the Hamburg Sud Group. A separate but not unrelated product, is Hull Fouling Analysis used to optimize the maintenance and efficient operation of the submerged ship’s hull area.
