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 173-metre-long module carrier to better maintain its position during loading and unloading.
The DP2 system also increases the deployability of the vessel for more complex transports, where a DP2 system is mandatory.
Bakker Sliedrecht has been asked to upgrade the vessel with a DP2 system. RH Marine 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.
Duplicate components
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,’ say System Architect Gerrit van Pelt of Bakker Sliedrecht and Sales Manager Products & Solutions Peter Copier from RH Marine. ‘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.’
Independently operating thrusters
Bakker Sliedrecht participated as a system integrator in the construction of the BigRoll Bering and its three sister vessels including the 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 renewables and oil and gas market. Due to the high ice classed certification, the vessel can be deployed in the most remote and inaccessible areas on the planet.
