    SKF Blohm + Voss Industries is launching a non-retractable fin stabilizer which can also stabilize vessels at anchor (zero speed). Thanks to the rotary vane motor which has proven itself in other products, the new SIMPLEX-COMPACT FZ stabilizer delivers high performance and features a compact design making it particularly suitable for small and medium-sized vessels. The fin stabilizer will be presented for the first time at SMM 2014 in Hamburg, 9-12 September.

    Gothenburg, Sweden 10 September, 2014: The new FZ stabilizer from SKF Blohm + Voss Industries offers a much improved stabilization, compared to previous systems on the market, when reducing roll of anchored vessels. Thanks to its rotary vane motor which has already proven to be successful with the supplier’s established stabilizers and control surface actuators, the new FZ stabilizer from SKF Blohm + Voss Industries achieves an operating angle of +/- 60°.

    Because there is no hydrodynamic buoyant force when stabilizing a non-moving vessel, the forces to counter the roll have to come only from the paddle movement of the fins. In light of this fact, the operating angle of the fin plays an essential role. The larger this is, the stronger the stabilization.

    Furthermore, because of the the strong capability of the motor, the surface of the fin can be reduced. This not only makes the purchase price more attractive, but also cuts costs during operation. As a result of the fin’s smaller surface, less water resistance is created for the vessel, which helps reduce energy costs.

    More comfort and less noise for passengers and crew
    At the same time, the motor’s performance increases the comfort level on board. On account of the fin’s large operating angle, the force can be transmitted for a long period. The movement of the fins becomes more powerful and more uniform. As a result, the jerk effect on board is almost eliminated.

    One important factor for a pleasant stay on board is the quiet running of the components, particularly when there is no engine noise, as is the case when stabilizing an anchored vessel. This is why SKF Blohm + Voss Industries overhauled the hydraulic system, which is also used in the SIMPLEX-COMPACT Z stabilizers. By converting to internal gear pumps, the structure-borne noises could be further reduced. The automatic adjusting of the pressure level to the required operation level and improvements enhance this effect.

    What further enhances the chance of a comfortable stay on board is the adaptive control which finds the ideal fin movement on its own when it comes to the roll of the vessel. The switching between stabilizing vessels at anchor or underway happens automatically. This makes for a simple and clear handling of the stabilizers and does not require any in-depth knowledge of the system on the part of the crew.

    Ideal solution for individual requirements
    SKF Blohm + Voss Industries custom produces the new SIMPLEX-COMPACT FZ stabilizer for its customers. The system comes in fin sizes between 1.40 m2 and 10.30 m2. Upon request, a different configuration can also be delivered which meets the strict regulations of the 2013 Vessel General Permit applicable for all US coastal waters. The integration of the stabilizer into the vessel’s structure and the commissioning are performed by our own engineers and designers in close cooperation with the shipyard. 

    An even stronger partner for the marine industry
    In early 2013, SKF has acquired Blohm + Voss Industries (BVI), the German manufacturer of ship components. With this acquisition, SKF intends to strengthen its product portfolio for the marine industry. Furthermore, SKF widens its access to the market by using BVI's world-wide leading network of Sales and Service partners. Customers will benefit from SKF's expertise as a knowledge engineering company in combination with BVI's focus on shipbuilding and ship operations. The new joint organisation will be an even stronger partner for the marine industry, supplying critical components and fast and reliable services, as well as developing new applications that address future challenges in the ever changing environment of the industry.
