DEME DIG UP SCHELDT RIVER
Built at Royal IHC’s shipyard in Krimpen aan den IJssel, the Netherlands, for Belgium’s DEME Group, the 7,950-cubic-meter dual-fuel (diesel and also LNG) receptacle dredge Scheldt River includes a Danfoss drive remedy developed to increase an inboard dredge pump and also rise power effectiveness with a tiny impact, minimal weight and also reduced quantity– while being durable sufficient to endure the rough aquatic setting.
The modular Danfoss VACON 3000 drive set satisfied IHC’s needs for viability for the aquatic setting, minimal weight, tiny impact and also reduced quantity. The drive set additionally added to the vessel’s general environment-friendly efficiency and also provided the versatility of style needed by IHC’s designers and also service technicians. The power component style was appropriate to the rough setting, being outfitted with details procedures to prevent dirt and also contamination polluting the semiconductors throughout ship building.
As an independent low-voltage (LV) and also medium-voltage (MV) drives vendor, Danfoss can supply this MV set that allowed IHC to make their very own personalized, incorporated remedy, the IHC MV drive.
The increasing of the vessel’s dredge pump with an A/C drive was enabled with power take-in (PTI) innovation, which permitted lots sharing in between the VACON 3000 and also the primary dual-fuel engine. This caused considerably greater power effectiveness.
Using transformer-less AFE innovation utilizing typical water-cooling, the VACON 3000 drive can work on reduced supply regularity and also voltage, for continuous outcome power. Energy is conserved in the accessories by decreasing the engine rate. VACON NXP LV drive components are used for various other applications consisting of pumps, thrusters and also energetic filters. The changing of drive control in between the inboard dredge pump and also the completely submersible dredge pump of 1,700 kW is carried out by a tool voltage switchboard, where the needed sinus filter lies.
A 2nd vessel of the exact same kind bought by DEME at IHC, the Meuse River which was released in November in 2015, makes use of the exact same VACON 3000 drive set.
