Low Resistance Hull Form Developed for BlueTech 42

Foreship BlueTech Ltd. and Foreship Ltd. have jointly developed a new super-low resistance hull form for the BlueTech 42 bulk carrier. The hull has low resistance through the speed range – not only at design speed. This gives the benefit for owners and operators to choose the speed based on their needs, as every speed is ECO-Speed.

Extensive use of in-house RANS-CFD together with innovative and unique design features were the cornerstones for the hull form development. Even the smallest details were optimized, but the entire wave formation was the dominating feature of the development.

The hull form was recently model tested successfully at Hamburg Ship Model Basin (HSVA), which is one of the most well-known and experienced model basins in the world. Majority of recent tanker and bulker designs have been tested at HSVA.

The outcome of this development was observed during model tests as the wave formation through the speed range was absolutely minimal and no following waves were observed on the wake of the ship.

The measured resistance was compared to HSVA database: some designs might be equal around certain speed, but none of them show such constantly low resistance as BlueTech 42 bulk carrier. These resistance figures ensure solid base for setting a new level in terms of a real through-the-speed-range ECO-design.

Similar kind of optimization routine and design guidelines can be utilized for all other BLUETECH-series of ships having full bodied hull form.
