The 80-knot ship concept , introduced by Norway’s former Viking Ships, now InSvivia Technologies, has been further developed now reaching 74% less fuel consumption, the designer tells World Maritime News.
In addition, the patent-pending technology has now been approved as a Norwegian patent, and the company has applied for a PCT-investigation for further international patent.
Under the concept, a ship is powered by turbines that make a hundred times gyro stabilization, and then, the ship, gaining on the torque force, is being propelled forward “as cast in the sea”.
In terms of design capacity, the ships in question would feature up to 16,500 in TEU, 17 meters in maximum depth and up to 300 meters in length overall. However, the design is also applicable to smaller ship designs.
Under the previous design, the company claimed up to 37% in fuel savings when compared to slow moving ships, based on results of CFD-analysis. The upgraded design has been further increased to achieve 74% less fuel consumption by replacing the four turbines with two larger turbines, and some small optimization of the air cavitation.
As explained by the designer, the larger turbines result in greater depth, which is solved by a swath-down hull that lifts the ship to a reduced depth for ports with low depth.
