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.

Danish Maritime Technology Conference 2016

A part of Danish Maritime Days 

For the first half of 2016, the key buzzword of the maritime industry have been ‘The Fourth Industrial Revolution’. The global maritime industry stands in the midst of a market with changing dynamics, where emerging technologies give endless possibilities with an unprecedented processing power.

The emerging technologies have opened up for new products and services that increase efficiency through the entire maritime value chain. The Danish Maritime Technology Conference looks at the key drivers emerging in and from the Fourth Industrial Revolution – the technologies, the products and the services that leads this market change.

The new waves of accelerating technological development require new forms of conducting agile business, given the speed at which innovation and disruption takes place. Members of Danish Maritime are global market leaders within the maritime industry, and together with specialists they will discuss their core challenges and present their solutions to a game changing market.
