Norway: New Rudder Force Detection for DP Operations Launched

 

The result of an 18 month joint development project between Kongsberg Maritime and Becker Marine Systems has come to fruition, with the launch of KBIMS; a sophisticated new support tool designed to enable more efficient use of propellers and rudders during Dynamic Positioning (DP) operations.

A first pilot installation has already been agreed for KBIMS, with a new Volstad offshore construction vessel, which is under construction at Fosen.

There are several advantages to using main propeller and rudder instead of azimuth thrusters during DP operations. For instance, there is no limitation of installed power and response times may be improved, therefore improving station keeping performance overall. However, with conventional rudder-propeller arrangements these benefits, which also include the possibility to reduce vessel emissions, are not always available, so Kongsberg Maritime and Becker Marine Systems set about developing KBIMS in order to improve performance for DP operations.

“KBIMS is able to enhance DP operations through several new technical innovations, made possible through Becker’s in-depth expertise in rudders and our own DP systems experience,” explains Nils Albert Jennssen, VP Business Development, Kongsberg Maritime. “The challenge was to find a more direct indicator of maneuvering performance than the vessel’s motion reaction detected by GPS or gyros. It clearly turned out that the closest value to describe performance was the rudder force itself, so this is what KBIMS measures.”

Once KBIMS is integrated with a Kongsberg Maritime K-Pos DP system, it can learn the characteristics of the rudder so the correct combination of rudder angle and propeller pitch/rpm is used. Exact measurements of the actual rudder force secures improved station keeping performance and more precise rudder control will reduce wear and tear of steering gear, rudder stock and bearings, so less downtime and maintenance costs are possible. Using KBIMS also fulfills regulatory requirements on DP and propulsion systems for long haul offshore operations.

In addition to the launch of the sophisticated new KBIMS tool, the two companies have also signed a new cooperation agreement to continue utilising their strengths within high performance rudder systems and DP systems respectively to enhance DP capabilities.

7th Annual International Port Security Conference

The SMi Group announces the 7th annual International Port Security Conference. The event will be held in London on the 1st and 2nd of June 2016.

The conference aims to bring together key decision makers in the industry to discuss modern methods of port security and provide effective learning experiences for all delegates through the carefully selected expert speaker line up.

Interacting with delegates from across the globe and hearing from industry leading experts will ensure delegates are up-to-date with high priority information that enables you to best secure your seaports, civilians and means of trade.

Topics to be discussed include terrorism, cyber terrorism, emergency intervention procedures, optimising technology use in security checks and case studies featuring some of the largest ports across the world. Our diverse range of topics will allow delegates to learn best practices for port security and understand further how other ports are resolving core challenges.
