Marine dredging and constructing contractor Weeks Marine Inc. (Weeks) has ordered a dynamic positioning and tracking (DP/DT) system, and eco pump controllers for the trailing suction hopper dredger (TSHD) MAGDALEN. Initially Weeks ordered the design and engineering for this new 6,540m3 TSHD and the supply of key components, such as the principal electrical and dredging systems.
The two efficiency enhancing systems, provided by our North American subsidiary IHC America Inc, will considerably optimise the MAGDALEN’s dredging performance, enhance fuel savings and reduce emissions. The 111m long vessel is under construction at the Eastern Shipbuilding Group in Panama City, Florida, and will be delivered in 2017.
“We are delighted to be providing Weeks with valuable support once again,” says IHC Systems Managing Director Rens Klootwijk. “They will benefit further from such advanced equipment, which will contribute to a more efficient dredging performance.”
Unique DP/DT system
IHC’s unique DP/DT system is the benchmark for TSHDs and has already been delivered to nearly 40 vessels. It provides more than the common vessel and environmental models and additionally processes the ‘third unknown’ – the varying forces generated by dredging and the interaction with the sea floor. This results in the capability to accurately maintain (and shift) the dredging track, course and speed.
IHC’s Eco Pump Control Package governs the vessel’s dredge pumps. This allows them to continuously operate at the most efficient speed, without operator interaction. The system’s artificial intelligence effectively optimises suction and discharge operations.
The combination considerably eases the operator’s task and has demonstrated substantial improvement of the hopper loading and unloading processes.
