Voith Linear Jet Offers Fuel Savings
Crew transfer vessel operators using the new Voith Linear Jet (VLJ) marine propulsion system can save over £75,000 in fuel costs in a season, the manufacturer claims. The cost saving, around 20 percent, is a key figure from the collection of extensive data from four months’ operation in a range of sea conditions, working at different speeds and with different loadings. The Voith Linear Jet, unveiled last year as a “world first” in marine propulsion technology, combines elements of two existing technologies: conventional screw propellers and water jets.
Design & Operation: Wind Farm Support Vessels
Offshore wind farm development has been led globally by the UK, followed by Germany. Both countries have governments with long term commitments to renewable energy. Denmark, Belgium and The Netherlands are building wind farms, but they are a long way behind the leaders in offshore wind. In 2014 the UK accounted for over 50% of all the offshore wind energy generated globally. All of these countries border the North Sea, a notoriously stormy sea area, which has a high frequency of wind to drive the turbines. Traditional survey vessels are first to arrive in a potential wind farm area.
Trearddur Bay Completes Sea Trials
BMT Nigel Gee Ltd, a subsidiary of BMT Group Ltd, has announced that windfarm support vessel Trearddur Bay, its latest design for Turbine Transfers, has successfully completed sea trials in the Solent, achieving 31 knots with 8 metric tons DWT. With sea trials completed Trearddur Bay has immediately started work for Dong Energy. Built by Aluminium Marine Consultants (AMC) on the Isle of Wight, Trearddur Bay was launched in December 2014. The vessel is 21m long with a beam of 7.0m and utilises BMT’s well proven catamaran hull form.
New Standard in Propulsion Efficiency and Onboard Comfort
According to the manufacturer, the propulsion system has performed convincingly all along the line and surpassed the expectations of her owner, the Welsh company Turbine Transfers Ltd, a subsidiary of Holyhead Towing Company. The VLJs are the main propulsion system of the DNV Classed 21m offshore service catamaran, which was designed for Turbine Transfers by BMT Nigel Gee and built by AMC. The Crew Transport Vessel will take service technicians to offshore wind farms at sites all around Europe, initially at the Westernmost Rough site off the Humber for Dong Energy.
