Barge Master has delivered its first Barge Master T40 (BM-T40) motion compensated knuckle boom crane, the company announced.
The BM-T40, installed on Wagenborg’s ‘Walk to Work’ vessel the Kroonborg, compensates for sea induced vessel motions in roll, pitch and heave directions at the base of the crane, up to three meters significant wave height.
The BM-T40 is designed for offshore support vessels that are used to transfer small loads and personnel to (unmanned) offshore oil and gas platforms or wind turbines. The BM-T40 features a small footprint and is designed to compensate for sea induced motions of a knuckle boom crane with a lifting capacity of 15mT at a 10 meter radius or 5mT at a 20 meter radius up to 35m height. Typical loads include hoses, tools, spare parts, maintenance equipment, small wind turbines and solar panels weighing 1.5mT to 5mT. The BM-T40 is also suited for ballasting or grouting operations. Besides the suitability of safely lifting loads, the T40 is manriding certified for safe personnel transfer.
Wagenborg will use the motion compensated crane to service and maintain NAM/Shell gas production platforms in the North Sea. Oil and gas platforms have become smaller and more flexible during the last 40 years. They no longer have a resident crew or helicopter pads which means frequent journeys to and from the platform by ship in order to perform maintenance work. With the new ‘Walk to Work’ vessel these operations are executed in a safer, more efficient and effective manner. The vessel is unique because multiple functions are combined for the first time. The vessel can accommodate 20 crew members and 40 service technicians, chemicals can be stored and transferred, and thanks to the Barge Master T40 system materials can be transferred safely with wave heights of up to three meters. Through utilizing new technology, NAM is able to safely continue harvesting gas on the North Sea.
Barge Master develops and produces motion compensation systems for the marine and offshore industry. The Barge Master T40 is based on the same principle as the Barge Master T700 motion compensation platform: roll, pitch and heave motions are actively compensated, while surge, sway and yaw are fixated. The motion compensation systems are developed together with Bosch Rexroth.
