... combines the knowledge about the optimum trim with the ability to achieve it MARINE ALIGNMENT FORCE force technology CFD & Model tests About FORCE Technology Christian Schack: “At FORCE Technology, we have performed trim model test on numerous vessels, among others tankers, container vessels, LNG carriers and ro-ro vessels. Our testing shows possible fuel savings of 3-15% at specific conditions. In overall fleet operations, typical savings can be as high as 3-4%. Further, we are one of the market leaders within CFD with many years of experience and specialists designated to developing the precision and usability of CFD calculations.” FORCE Technology is a leading technology, consulting and service company on the international market. Force Technology's maritime division is the former Danish Maritime Institute, founded in 1959, and experts in both scale model tests and computer modelling. FORCE Technology offers both deep water towing tank and shallow water manoeuvring basin analysis, wind tunnel analysis and CFD analysis. Anders 0rgard Hansen: “OSK-ShipTech A/S uses the state of the art computational fluid dynamic software STAR-CCM+ from CD-Adapco for hull form optimisation and motion studies. The resistance can be calculated with a precision of more than 95%. The optimum trim can be investigated by calculating the resistance for a range of trims over a range of draughts to find the optimum trim” www.OSK-ShipTech.com marin CFD & Model tests Patrick Hooijmans: “Probably the easiest way to save fuel during transit is to trim a vessel to its optimum draught and trim. From either model tests or CFD calculations, fuel reductions ranging from 2 - 7% have been found, depending on ship type and speed. However, for every type of vessel the ideal trim is different. MARIN can offer CFD calculations and model tests to determine the influence of trimming on the power requirement, thus fuel consumption. Typically a matrix of 3 - 5 displacements, 3 - 5 trimmed conditions and about 6 speeds will give sufficient information to optimize the trim for minimum fuel consumption.” www.marin.nl About OSK-ShipTech A/S Ole Steen Knudsen A/S was established in 1966 and has for several years been one of the leading Naval Architect companies in Denmark.

The FuelSaver module is designed to be based on either of the below techniques. Model test results - typically obtained from towed and self-propelled model testing in water. Such tests are often made on the design stage for a series of sister ships. Often these tests are concentrated around the design point for the ship, i.e. to prove that the specified speed at the design draught can be obtained with the expected engine power. In such cases it is important to advise the yard or designers that more combinations are required in order for the Easeacon FuelSaver to calculate better trim and...
