Drive coupling specialists Vulkan, based in Germany, is supplying both fixed and flexible drive couplings to Brazil’s home-built burgeoning offshore energy sector, and interestingly is also involved in a project to develop a nuclear-powered submarine propulsion system for the Brazil Navy. The diesel engine beats to the sound of a pulsating drum in its cycle giving rise to shaft vibration. Secondly, slight misalignments, in connected drive shafts also need to be smoothed out, and to achieve this, flexible couplings incorporate rubber-like polymer subrstances in their design – elastomers.Vulcan explains that compound research in its R&D facility with highly specialized vulcanization technology has led to the development of an elastomer with considerably higher power density  – the 'Acotec' compound. This new compound distinguishes itself from other conventionally used materials not only through its enhanced tensile and tear strength and increased ultimate ... [More]

Damen delivered special Shoalbuster Smit Lamnalco

The recently delivered ‘SL Mbissi’ will be the next Damen-built vessel in fleet of Smit Lamnalco. Nevertheless, the 25 metre shallow water workship is special in more ways than one: It’s the first-ever Damen Shoalbuster for Smit Lamnalco. Although Smit Lamnalco, leading provider of integrated marine services, already deploys a lot of Damen-built vessels – six of which having been delivered in the past 15 months alone – it had yet to order a Damen Shoalbuster SD. The series’ name is a poetic licence to ‘shallow draught’ (SD). Standard turned bespokeThe ‘SL Mbissi’ was built at Damen Shipyards Hardinxveld (the Netherlands) which also designs all Damen Multi Cat and Shoalbuster ‘jack of all trades’ workships series. The SBu 2508 SD is also special in that it is a standard design turned tailor-made vessel. “We sought a draught not exceeding 1.80 metres, to cope with a bar in the vessel’s operational area&...

New Shipbuiling Contract for Cassens-Shipyard in Emden

German shipping company Norden-Frisia has ordered a new diesel-electric ferry which will be built at Cassens Werft in Emden. The delivery is expected in summer 2015. According to the shipping company the new build with a modified exhaust after treatment system from Kurre Abgastechnik and with a diesel particle filter. Norden-Frisia says that the power plant will reduce emissions by up to 90% and very fine particulates by up to 99%, “…with this we will have almost the same emission values like with a natural gas driven ferry”. Same like the FRISIA VIII, which was the first German island ferry awarded with the German environmentally quality certificate “Blue Angel Ship Design”, also the new build is planned to receive this award.The vessel will be of identical dimensions to Norden-Frisia’s FRISIA IV, which features 70.7 m. It is planned to have the double ender’s Voith Schneider propellers in combinatory operation, a development which the owners... [More]

MAN’s New EcoCam reduces fuel consumption

MAN EcoCam further optimises slow-steaming concept MAN Diesel & Turbo has introduced the MAN EcoCam as a retrofit solution for the low-load optimisation of its low-speed, mechanical engines with single turbochargers. The EcoCam offers significant fuel savings of 2 - 5 g/kW – with short payback times – and delivers an increased Pmax cylinder pressure through the adjustable exhaust-valve timing.Christian Ludwig – Head of Retrofit & Upgrade – MAN Diesel & Turbo, said: “Slow-steaming is now an established industry standard across all segments, including the tanker and bulker markets, and MAN continuously seeks to further refine its technology and improve efficiency. The MAN EcoCam adjusts the exhaust-valve timing between 10 and 60% load, giving a 2 - 5 g/kW fuel saving with minimal to no interruption to a vessel's schedule during installation. . For smaller engines, this can result in a payback period of as little as 1½ years as is the case,... [More]

Ghost ships on the Oceans – Who says it doesn’t work? Part 2

New functions for the autonomous ship The KISS principle will also be applied to the ship itself and it is also important to look at how existing vessels can be modified to support unmanned operation. At the hardware level, technical modifications will be necessary, for example to the fuel-processing system, while an electric-powered water-jet for back-up propulsion and steering may have to be retrofitted.New sensors to replace the look-out are also an important part of the unmanned ship. A combination of high resolution radar, low-Iight and infrared cameras form the 'advanced sensor system'. Most of the technology involved is already available and its adoption would be more a question of cost than of general availability. The sensor-system will be integrated with more conventional equipment such as the AIS system and ARPA radar. Computer-based data fusion, using Information from the various sensors, will further increase the capability of the sensor system. All these systems are alre... [More]

IHC Merwede has been awarded the contract for the design, construction and delivery of a 23,684kW self-propelled cutter suction dredger (CSD) from Royal Boskalis Westminster. and the pump ashore capacity is of 15,600 kW. The new CSD is a replacement investment.  The 152m-long and 28m-wide dredging vessel will be one of the largest CSDs of its kind in the world, IHC said. The total investment amounts to around EUR 170 million and construction of the vessel is expected to take more than three years. Much attention has been paid to the design in terms of safety, the environment and increased operational workability. A particular feature of the vessel, which has a maximum dredging depth of 35m, is the widening of the aft ship in order to reduce the draught. It offers accommodation for 45 crew member.This Cutter Suction Dredger (CSD) is a suction dredger equipped with a rotating cutterhead. The CSD is positioned on spuds and anchor wires during dredging operations. A CSD is ... [More]

SMIT, a member of Royal Boskalis Westminster N.V., says that their harbor tug “Smit Elbe”, which works in the Port of Rotterdam, has become the first tugboat in the Netherlands which runs with GTL (Gas-to-Liquid). GTL fuel is a synthetic fuel, produced from natural gas by chemical transformation. GTL fuel is clean: it is non-toxic, biodegradable, and does not contain nitrogen or sulfur. GTL Diesel is pollution free with no sulfur, aromatics, or toxic ingredients -- so pure that one can even drink it; simply hydrogen and carbon. Blending just 20 percent GTL diesel with conventional diesel results in a fuel that exceeds nearly all international environmental standards for 2015. SMIT ELBE runs on GTL The tug will run on GTL for about six months to determine whether the fuel is able to effect a remarkable reduction in emissions without the engines being adapted. The drive line of the tug consist of two fixed pitch ASD propellers driven by two Caterpillar 3516B TA HD/C engines,... [More]
