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.

TOC Americas

TOC (The Terminal Operations Conference) has long been considered best in class by container terminal operators and their suppliers. Over time, TOC has evolved and whilst they continue to deliver the highest quality technical content in line with their heritage, they also recognise that they must now hear from stakeholders higher up the cargo chain. Therefore, there are now two distinct elements to the event:

The exhibition is a showcase for port & terminal technology and operations plus TECH TOC, the free to attend technical conference aimed at terminal operators and their suppliers. Many suppliers come together to showcase cutting edge solutions to their clients, the terminal operators and ports.

More recently, the events now placed a new focus on the container supply chain making them the premier business and networking event for the stakeholders, including shippers, carriers and 3pl’s as well as the global operators and port authorities. This conversation takes place in the more recently created Container Supply Chain Conference.
