Research project: Service Performance Analysis cuts fuel bills


Wageningen / The Netherlands, 25 September 2007 - The high level of fuel oil prices and the increasing restrictions on exhaust gas emissions have urged ship owners to look into reduction of fuel consumption while maintaining schedule integrity. Fleet comparisons have shown that fuel consumption of sister ships on the same trade may vary up to 10%. Reasons are differences in hull, propeller and machinery, but also smart operation of a vessel can reduce fuel consumption significantly. Especially optimum trim, weather routing, speed control and auto pilot setting contribute to fuel savings by more than 5%.

To analyse the parameters of optimal fuel efficiency, the Joint Industry Project “Service Performance Analysis” (SPA-JIP) develops a method for a speed-power performance analysis for ships in operation. With the project results, participating companies will obtain a standard and software tool for continuous performance monitoring on board their ships. The tool can optimise ship operation with regard to ballast, trim, routing or speed setting as well as improve the ship systems such as auto pilot or CPP pitch setting. It also enables advantageous planning of maintenance on hull and propulsion. The findings can result in concrete measures to assist crew in fuel reduction. Ship owners benefit from detailed data enabling fleet comparison and thus optimisation of ship operation.

As part of the project, monitoring campaigns are conducted on board four ships. In the first project phase, the speed-power analysis method is developed based on monitoring results. Data are generated from sensors already on board and made available through Voyage Data Recorders (VDR). Vessel speed, shaft torque and rpm are basic input signals. These measurements will be combined with wind and wave conditions. Performance results are compared with benchmark data derived from speed trials, historic performance data or results from sister ships. In the second project phase, developed software will be tested on board these vessels.

The Dutch research and development institute MARIN is the manager and main contractor of the Joint Industry Project. The project is conducted in close cooperation with ship owners and operators, class societies, VDR suppliers and fuel consumption specialists. Participating companies include Danaos, DNV, Germanischer Lloyd, Hapag Lloyd, L3-SAM, Lloyd’s Register, Maersk, Marorka, NYK, Stena, Stolt-Nielsen, UECC, Wagenborg and Wallenius. Further partners are invited to join the project.

The project has just started and is scheduled to deliver final results in late 2008.
