The delivery of the ‘Aquarius-G’ and her sister ship ‘Astra-G’ to offshore services company Rederij Groen marked a milestone in Offshore Support Vessel construction. Never before, such Chasers have been purpose-built. The vessels have been designed by Saltwater Engineering in close cooperation with both Rederij Groen and Maaskant Shipyards Stellendam. Both Seismic Research Support Vessels were constructed by Maaskant Shipyards Stellendam, part of Damen Shipyards Group. “Indeed, all our other SRS Chaser vessels so far involve converted fishing trawlers”, Henk Groen, director and proprietor of offshore company Rederij Groen notes about his new twins. “Having designed them to our specific needs right from the drawing board, significantly enhances the vessels’ deployability and performance. Their sharply reduced sway and manoeuvrability are just two examples”, Mr Groen adds. The ‘Aquarius-G’ and sistership ‘Astra-G&rs... [More]

40 M OFFSHORE SURVEY COASTAL VESSEL „FUGRO HELMERT” LAUNCHED

In November 2011 Fassmer Shipyard, Germany, and Fugro N.V., Netherland, signed the contract for the new 40m „Fugro Helmert”, a new Offshore Survey Coastal Vessel for hydrographic and geotechnical tasks in worldwide operation. Fassmer was assigned to design and build the vessel in a time period of 20 months. The delivery is scheduled for August 2013.

Volvo Penta D13 has now further been developed to meet EPA Tier 3 – the new marine environmental emission standard. The new version of D13 offers improved environmental properties with basically unchanged low fuel consumption. The D13 is a diesel engine that has been developed within the Volvo Group. It is among the world’s most proven and is currently in operation in more than 450,000 heavy-duty applications, including buses, trucks and construction equipment. At Volvo Penta, this engine is further developed for use in industrial applications for both off-road and electricity production and in unique custom marine applications. This 13-liter diesel engine combines the best of two worlds: the exceptional durability, low fuel consumption and minimal emissions that come from its automotive background and the high torque and power brought by the thorough marinization. D13 MH is available in five models with outputs from 400 to 600 hp. High torque at low rpm is a Volvo Penta ha... [More]

The “Waterspreeuw”: a tailor-made hybrid patrol vessel for Amsterdam’s complex network of waterways Damen Shipyards Hardinxveld-Giessendam recently delivered an exceptional vessel, the “Damen Patrol Vessel 1304 Hybrid”, designed and constructed for Waternet (the Water Network Foundation). The most striking features of this hybrid patrol vessel are that it is clean, quiet, and can sail under Amsterdam’s bridges along the through routes. The “Waterspreeuw” – meaning “Dipper” in English – was ceremonially named by the Amsterdam Executive Councillor Carolien Gehrels on 17 June 2013. Reduced emissions  Waternet is an innovative water organisation that takes the entire water cycle as its basis. In order to achieve its sustainability objectives, it collaborates closely with other parties. By choosing a hybrid, multifunctional vessel, Waternet is taking the lead in reducing emissions from vessels within the municipal... [More]

IMPROVED PROPULSIVE EFFICIENCY BY WEAKING THE PROPELLER HUB VORTEX

By Peter Pospiech at June 20, 2013 05:13
Filed Under: Company News, drive systems
Weakening the propeller hub vortex behind the propeller decreases propeller resistance and manifests itself as increased thrust. The deflection of the flow aft of the propeller by the optimized profiled fins reduces the propeller torque. In addition to the improved propulsive efficiency, the new Wärtsilä EnergoProFin propeller can also be applied to reduced propeller-induced noise and vibrations.  Wärtsilä's EnergoProFin and normal propeller in comparison Wartsila EnergoProFin  Fuel prices have increased considerably over the last years, making propulsion efficiency even more important than before. The energy losses of a propeller are among other things related to flow phenomena around and behind the propeller boss. Installing the new Wartsila EnergoProFin (WEPF) could increase the overall propulsion efficiency by up to 5% with a payback time of less than one year, reports the company. The result on investment period is relatively short thanks to the attr... [More]

First introduced at the turn of the millennium, MAN PrimeServ – MAN Diesel & Turbo’s service division – recently retrofitted its 20,000th slide fuel-valve. Christian Ludwig – Head of Retrofit & Upgrade – MAN Diesel & Turbo, said: “Slide fuel-valves have proved to be very popular within the marine, two-stroke market. Really, it’s a case of having introduced the right technology at the right time and the slide fuel-valve’s strong market performance is testimony to the fuel savings and increased environmental profile it brings to working vessels. It is important to note that slide fuel-valves improve the low-load operating capability of engines.” Slide Fuel-Valves Slide fuel-valves come as standard on all new MAN B&W engines but can also be retrofitted on MC engines. The slide fuel-valve eliminates the so-called ‘sac volume’, which reduces fuel-oil consumption and, furthermore, eliminates dripping from the ... [More]

The new Wärtsilä LMT-3510 thruster provides more available force and excellent bollard pull performance, which are essential factors in offshore dynamic positioning applications. Wärtsilä is continuously improving its thruster portfolio in response to market demands, classification requirements, and feedback from thruster products in operation. In the coming years Wärtsilä will renew its entire thruster portfolio. The Wärtsilä LMT 3510 thruster is the first result of this extensive development programme that uses new insights and the latest technical and hydrodynamical knowledge. The main objectives for the LMT-3510, as compared to the already existing LMT-3500, were: 1.  To improve the hydrodynamic efficiency of the thruster, 2. Incorporate latest knowledge with regard to the propulsion driveline and structural strength of the thruster The new thruster has found a broad market acceptance, as is manifested by the fact that, in a limited time...

Rolls-Royce Plc has delivered the first of a revolutionary new design of cargo ship which will reduce CO2 emissions by up to 40 per cent, thanks to a combination of cutting edge marine technology, including a wave-piercing bow and an engine powered by natural gas, whereby the gas is stored as liquefied natural gas (LNG). The first Rolls-Royce Environship, of NVC 401 LNG design, the Eidsvaag Pioner, has been delivered to Norwegian company Eidsvaag AS this week, and will soon enter service on a year-round schedule delivering feed to numerous fish farms around the Norwegian coast. The Environship, which can be adapted for different ship types, incorporates a range of Rolls-Royce technologies to deliver efficiency savings for ship owners. When compared to similar sized diesel powered ships, the CO2 reduction can be up to 40 per cent. Neil Gilliver, Rolls-Royce, President - Merchant, said: "The Environship has now moved from concept to reality with the successful delivery of the first ship... [More]
