Wärtsilä markets new engine to tanker sector

For greater reduced emissions and fuel consumption Wärtsilä has announced that it had started up its new 6-cylinder Wärtsilä RT-flex48T engine on 24th November 2011 at the facilities of Wärtsilä licensee QMD (Qingdao Qiyao Wärtsilä MHI Linshan Marine Diesel) in China.This new engine is the result of further development of the existing Wärtsilä RTA48T engine and is being marketed to the smaller bulker and tanker sectors, including Handysizes and Handymaxes.By introducing this new engine, Wärtsilä said that it had completed its adaptation of its range of low-speed RT-flex engines for all bore sizes. The engine type is also available in other cylinder configurations.With the implementation of the RT-flex common-rail technology, the conventional RTA48T engine has been upgraded to feature electronically controlled fuel injection and exhaust valve activation for greatly reduced emissions and fuel consumption.One great advantage is its smokeless operation at all engine load levels, the company claimed."We are extremely pleased to add the Wärtsilä RT-flex48T engine to our portfolio of common-rail low-speed engines. We now have this industry-leading technology available for all bore sizes in our current low-speed engine portfolio," said Martin Wernli, president, Wärtsilä Switzerland and vice president, product centre 2-stroke.The key features of the RT-flex common-rail system ...

SCOD presents a DynaWing Solar Hybrid Supertanker

The largest and the greenest Post Panamax Vessel to be built SCOD Presents Deliverance, a DynaWing Solar Hybrid Supertanker that qualifies as the Largest and by far the Greenest Post Panamax Vessel to be built and as such the most Economical form of Crude Oil Transport to and from any part of the Globe.To reduce fuel consumption and GHG emissions by up to 75% this superior fluid dynamic Emax Supertanker obtains half of her power from LNG and the other half from the latest advances in Solar and Wind Power technology .The Emax Deliverance is a 2 million barrel 330,000DWT Supertanker designed specifically for the newly enlarged locks of the Panama Canal which will accommodate vessels that have a maximum length of 1,395 ft (426m), a beam of 176 ft (54m) and a draft 59 ft (18m).Being longer, narrower and having less draft than previous 2 million barrel VLCC's, the hull of Deliverance produces less drag which in conjunction with twin CRP Hybrid Propulsion Pods reduces fuel consumption and GHG emissions by 35%. An additional 20 to 30% reduction is achieved with her 500,000 sq. meter DynaWing boom furling sails and another 15 to 20% reduction by her Solbian Solar ...

New high-activity antifouling

High performance and low environmental impact PPG Protective & Marine Coatings (PPG) has launched a new antifouling, Sigma Nexeon 750, claimed to deliver optimum protection against hard fouling and whitening, with high performance and low environmental impact.The company says that the new coating was developed to meet the challenge of how to keep a ship's underwater hull clean from discoloration and/or fouling pick-ups while stationary in seawater, and at the same time to minimise environmental impact without compromising operational efficiency.PPG adds that with prolonged outfitting periods for new-build LNGCs, FPSOs, drill ships, offshore structures and even general commercial ships, there is increasing demand for vessels to look clean with good aesthetics. Customers need the appearance to be good at delivery stage and do not want to incur costs for cleaning the underwater hull before delivery.Sigma Nexeon 750 is designed to address these issues, being a copper-free, high-activity antifouling based on self-polishing binder technology. Claimed features for the coating include protection of the underwater hull from fouling and discoloration, highantifouling performance for static and low-activity vessels for new-build, consistent polishing at stationary service conditions, and keeping hulls clean through long outfitting periods in the newbuilding stage.Nexeon 750 is recommended as a ...

Ferry efficiency improved with rudder

Maximise propulsive efficiency, reducing fuel consumption and emissions Three DFDS Seaways ferries are to be upgraded with Rolls-Royce Promas Lite systems to maximise their propulsive efficiency, reducing fuel consumption and emissions.Dover Seaways, Dunkerque Seaways and Delft Seaways serve the Dover- Dunkerque route across the English Channel. The three sisterships were originally designed for a speed of 26.5 knots, and have propellers optimised for that speed. The requirements for the current route are a service speed of 18-19.5 knots, with a few knots more available to recover delays, and responsive manoeuvrability in port. The ferries are equipped with twin screws and two engines per shaft. Normal sailing on the current route can be maintained on one engine per shaft (1+1), with 1+2 and 2+2 available if more power is needed.Rolls-Royce says that under these circumstances a substantial improvement in efficiency could be won by just fitting new blades to the propellers; blades designed to match the present operating profile. But it was decided to go a step further and adopt a Promas Lite solution, so gaining the advantages of new blades plus the additional efficiency improvement from hydrodynamic integration of the propellers and the existing rudders.The conversion work for each vessel ...

Europe s most productive ports

Spanish ports scored 5.8 out of a maximum seven points The Global Competitiveness Report 2011-2012 put together by the World Economic Forum suggests that ports in Germany, Holland, Belgium, Sweden, Finland and Denmark are among the most productive in Europe.These are followed by Spain, in seventh place, ahead of the UK, Italy and France.Surprisingly, Spanish ports scored 5.8 out of a maximum seven points.Source: Port Strategy

Containership owner Seaspan receives DNV s new Triple-E rating

A tool to assist ship owners in improving their environmental performance Containership owner Seaspan has received DNVs new Triple-E rating. Triple-E is a voluntary self-improvement tool designed to assist ship owners in continuously improving their environmental performance. It was Seaspans vessel MOL EMERALD that received the rating a testimony to active environmental management and energy efficient transportation of goods.The rating, which was handed over at a ceremony in Vancouver, Canada by DNV President Tor E. Svensen, has been designed as a voluntary tool to help ship operators improve their organisational performance, identify ways to minimise their environmental impact and optimise their fuel consumption and thereby reduce costs.The Triple-E rating is based on the capture of environmental and operational data from ships. The common denominator of the requirements covered in the rating is that most of them can easily be influenced by the owner of the ship; either by themselves or with the assistance of third parties such as DNV. Thus in effect the Triple-E encourages a process of continuous improvement, says Tor E. Svensen.With the handing over of the rating, Seaspan Ship Management became the first containership owner to receive a Triple-E rating.Seaspan was very excited to be the first ...

Bureau Veritas puts new focus on operational efficiency

Being efficient means more than saving fuel Classification society Bureau Veritas says continuing pressure on emissions, coupled with rising oil prices, puts a new focus on operational efficiency, so BV believes the scope of efficiency must be widened.Writing in the Bureau Veritas Marine Business Review 2011 Bernard Anne, managing director of BVs marine division says: Efficiency has to take on a new meaning. To be efficient means more than optimising a ship to burn less fuel when loaded and at its design service speed. It must burn less fuel and cleaner fuel across a wide range of loading conditions and a wide range of speeds.To be efficient means more than saving fuel, it means burning the right fuel in the right place, making a pathway for the use of gas, nuclear and fuel cell solutions. To be efficient means operating the ship in the optimum way for every environmental condition, and that means having crew with the right training, the right support and the right feedback on operating conditions to make the right judgements. And to be efficient above all means operating without incident, without pollution, without breakdown, and without loss of life.Class can help with that quest for new ...
