VFD technology aids vessel efficiency
An organisation which tackles marine contamination along the coast of British Columbia, Canada has made three of its new vessels more efficient using Invertek Drives variable frequency drive (VFD) technology.
Western Canada Marine Response Corp’s (WCMRC) newest pollution control vessels have been fitted with Invertek Drives Optidrive P2 55kW and 75kW VFD, a type-approved by DNV Classification Society for their bow thruster and winches control. The drives system was supplied by Invertek Drives Far East Pte Ltd and the scope of supply includes thruster control, electric motor, control panels, commissioning and sea trial.
“The installation and commissioning of the electric system, controlled by the Optidrive P2, enhances the manoeuvrability of the vessel, the control of the thrusters is much more accurate and precise,” said Henry Beh, general manager of Invertek Drives Far East Pte Ltd.
“Additionally, the electrical thruster system is more energy efficient and easy to maintain, there is no problem with hydraulic oil or contaminants leaking at hose connectors and valves.”
Lower starting current
The Optidrive VFD has much lower starting current of motor, compare to traditional starting method, thus allow for optimum sizing of vessel power generation system, and further enhances fuel efficiency.
Matthew Mylemans, project manager at WCMRC said: “The 100 per cent efficiency of the thrusters is a great result and we’re looking forward to adding this green technology to the fleet.”
The Gulf Sentinel, Strait Sentinel and the Coastal Sentinel vessels have recently been commissioned at ASL Shipyard, Singapore.
