Bakker Sliedrecht and RH Marine will upgrade Roll Group’s ice class vessel BigRoll Bering with a Dynamic Positioning 2 system (DP2). This allows the module carrier to better maintain its position during loading and unloading. It also increases the deployability of the vessel for more complex transports, where a DP2 system is mandatory, such as the transport of wind turbine foundations.

Bakker Sliedrecht, acting as the main contractor, has been asked to upgrade the vessel with a DP2 system. RH Marine, partner of Bakker Sliedrecht and part of Pon Holdings, supplies the in-house developed DP2 system, which includes the computers, screens, control panels, joysticks and the DP software. In addition, the wind sensors, motion sensors and Differential Global Positioning Systems are also part of the delivery.

Bakker Sliedrecht supplies the switch boxes, cables for communication and power supplies, installs and commissions the system. Every component is duplicated according to classification, so that in the event of a single error in the system the ship can remain its position. “The DP-system improves the comfort of the vessel’s control. The captain or helmsman can stop the ship at the push of a button. Because the DP system is DP2-class certified, it can also be used for complex jobs such as transporting foundations for wind turbines at sea, for which this classification is required,” say System Architect Gerrit van Pelt of Bakker Sliedrecht and Sales Manager Products & Solutions Peter Copier from RH Marine.

In this project Bakker Sliedrecht and RH Marine are each contributing with their own expertise and complement each other. “Normally we have a lead time of 24 weeks for the installation of a new DP2 system, but by scaling up, our flexibility and working closely with Bakker Sliedrecht, we can complete it in thirteen weeks,” says Copiër.

BigRoll Bering propulsion system
Bakker Sliedrecht participated as a system integrator in the construction of the BigRoll Bering and its three sister vessels BigRoll Beaufort, by COSCO Dalian Shipyards in China in 2016 and 2017.

The system integrator supplied, assembled and commissioned the electrical systems on-board. Bakker Sliedrecht also participated in the design of the innovative propulsion system for the Module Carrier vessels. The thrusters are installed in such a way that they can operate independently. The design prevents all systems from failing simultaneously. There is also a torque option, which ensures lower fuel consumption and thereby reduces operating costs.

The BigRoll Bering is specially designed to transport heavy and oversized objects for onshore and offshore projects. Roll Group is active in combined land and sea projects for engineered heavy transport for all markets including the renewable and Oil & Gas market Due to the high ice classed certification, the vessel can be deployed in the most remote and inaccessible areas on the planet.
