Modelling Software Drops Fuel Use by 5.8%
Finnish ship operator Bore has reduced fuel consumption on three ships by 4 to 6 percent percent using 3D ship modeling software, industry news site The Motorship reports.
The program lets operators adjust vessel speed to achieve maximum fuel savings in the face of changing weather and conditions, reducing fluctuations over the course of a voyage.
Bore installed the ClassNK-Napa software on the Bore Sea for full-scale sea trials and, after seeing fuel savings of 5.8 percent, added the software to two additional vessels, the Bore Song and Seagard.
The company is now planning to install the software on five additional ro-ro vessels.
The Bore Sea trials also identified the potential for additional savings of 10 percent that may be achieved with the installation of a shaft generator frequency converter that allows the engine to operate at variable rpm.
Napa and ClassNK, the classification society that recently announced plans to acquire the software company, also plan to share data from in-depth sea trials on six different ships, including a variety of vessel types, in the hope of identifying ways of saving through improvements to schedules, speed, route, and trim.
