Wärtsilä, the marine industry's leading solutions and services provider, has further developed its dual fuel technology and introduced a more powerful version of its popular Wärtsilä 34DF engine. The Wärtsilä 34DF engine has proven to be a highly efficient and reliable solution for a wide range of vessel applications. The latest version is expected to expand that range even further. Lower fuel consumption of this engine will further improve its environmental performance.

Since 2003, the Wärtsilä 34DF has paved the way in the LNG-fuelled offshore support vessel market. Today this product is being mainly used in tugs, ferries, Ro-Ro, Ro-Pax and workboats.The new and upgraded version of the Wärtsilä 34DF engine increases the efficiency in both liquid and gas operating modes and offers a power increase up to 500kw per cylinder.

This increased output means that the Wärtsilä 34DF now covers a power range from 2,9 MW to 8 MW. In addition to the increase in power, fuel economy is also enhanced, especially when operating in liquid fuel mode. This, together with the high loading capability and the proven reliability of the Wärtsilä 34DF engine, is seen as giving the new version a strong competitive advantage.

"The Wärtsilä 34DF engine has been a popular choice of ship owners, operators, and yards for a long time already, and this next generation version will certainly enhance its popularity. By improving both the power and fuel efficiency, we aim to maintain the leading position that we have in gas engine technology and as a gas engine manufacturer. It is also important to point out that the environmental performance of the Wärtsilä 34DF is already excellent, and by lowering the fuel consumption we are also lowering the exhaust emissions even further," says Mr Giulio Tirelli, Director, Wärtsilä Ship Power, 4-stroke Portfolio & Applications.

When operating in gas mode, the Wärtsilä 34DF engine is already compliant with IMO Tier III regulations without any secondary exhaust gas purification systems. Also when fuelled by gas, the SOx and CO2 emissions are notably reduced, and smokeless operation is attained. In liquid fuel oil mode, the Wärtsilä dual-fuel engines are fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention. The engine is able to operate efficiently and economically on low sulphur fuels (<0.1% S), making it suitable for operation in emission-controlled areas. The newly obtained certification of emission standard compliance from the United States Environmental Protection Agency (EPA) for the Wärtsilä 34DF further endorses the environmental compliance of this engine.

MAN Diesel & Turbo is to supply eight engines for the diesel-electric propulsion of two cruise ship newbuildings to Fincantieri Cantieri Navali Italiani S.p.A., world leader in cruise shipbuilding. The company is delivering the engines in cooperation with Alfa Laval who will supply accompanying exhaust-gas-treatment systems (PureSOx) for sulphur-oxide removal.

Each cruise ship will be powered by 2 × MAN 9L32/44CR + 2 × MAN 12V32/44CR engines, providing a combined output of 23,520 kW in a diesel-electric propulsion arrangement. The engines will operate with MAN Diesel & Turbo’s well-proven, state- of-the-art, common-rail injection system, suitable for both heavy fuel oil and distillate fuels. This technology, developed in-house by MAN Diesel & Turbo and fully optimised for its engines, provides superior performance in terms of fuel consumption and smoke emissions, especially at part-load.

Sokrates Tolgos – MAN Diesel & Turbo – Head of Cruise & Ferry Sales said: "We feel extremely honoured to have won Fincantieri, the world’s largest cruise shipbuilder, as a new customer for our engines in this high-added-value market segment. Fincantieri’s and Viking Ocean Cruises’ confidence in realising such a technologically leading and innovative cruise project with MAN Diesel & Turbo and Alfa Laval, our consortium partner, signals a new era of cooperation. We consider it an historical step for our future growth in the cruise and ferry business.”

Tolgos continued: “By combining MAN’s efficiency-leading 32/44CR engines with the PureSOx exhaust-gas-treatment system, these super-luxury cruise vessels can fulfill the increasingly stringent global requirements for permissible sulphur-oxide emissions in the most economical manner possible. This especially applies to the demanding limit of 0.1% sulphur fuel equivalent in Emission Controlled Areas (ECAs).”

With a total passenger capacity of 936 and a crew to passenger ratio of approximately 1:2, the ships are destined to serve the segment demand for small, super-luxury vessels. Delivery of the two newbuildings to the ship owner is scheduled for early 2015 and early 2016, respectively.

Viking Line to recycle vegetation brushed off from bottoms of ships

Viking Line, the Finnish cruise ferry company, says nearly all vegetation removed from the bottoms of ships is recovered for recycling following an upgrade of diving robot employed by the DG – Diving Group.

“The vegetation removed using the new brushing equipment is absorbed into the cleaning machine which filters the vegetation from the water. Clean water is returned to the sea and the organic mass is collected in sacks. This upgraded brushing equipment marks a new milestone in the joint efforts of DG-Diving Group and Viking Line for cleaner sea and dock basins,” the company said in a statement.

The aim is to recycle the collected organic waste in the best possible way, so Viking Line is currently investigating together with its partners whether the scrubbing waste can be used in the production of biogas. “The recycling of organic waste into biogas is the primary alternative due to the positive experience in the separate collection of food waste onboard Mariella, Viking Grace and Viking XPRS, and inspired by advice given by an expert in the field,” said Juhani Suvilampi from Watrec Oy.

Herkules Private Equity has agreed to buy life saving equipment companies Umoe Schat-Harding and Noreq. The combined group will have pro forma net sales of NOK1.2 billion in 2013 and their product ranges will complement each other well. The merged company will also have the largest service network of its kind in the world. The move means consolidation in the life saving equipment market, which remains fragmented at the moment, Umoe Schat-Harding said in a statement.

Trimline upgrades Thomson Celebration to Platinum status

Trimline has completed an ambitious refit of Thomson Celebration, a 33,930 gross ton cruise liner that has since been added to Thomson Cruises' Platinum collection, following the six month refurbishment.

Undertaking the majority of the upgrade while the ship was at sea, Trimline worked carefully around the 1,250 passengers and 520 crew to ensure the work was carried out to the highest standards, but with minimum disruption to the day-to-day operation of the vessel.

Sailing through Cyprus, Israel, Egypt and Jordan, the 45-strong Trimline team upgraded 478 cabins including fitting new carpets, curtains, bedding, and the installation of new televisions and kettle facilities. The Deluxe Cabin refurbishments called upon Trimline's expertise in interior design, requiring the installation of new sofa beds to maximise limited cabin space. 624 bathrooms were also upgraded with new tiling, fixtures and fittings from Grohe, and vanity units with Italian stone tops. From November 2012 to May 2013, the team used 326 tonnes of materials.

John Westgarth-Pratt, Captain of Thomson Celebration, said: "Given the scope of work and the number of Trimline staff, the manner in which the team were managed throughout their stay on the vessel was a credit to the company. The communication and co-operation Trimline established with the ship’s company throughout the project was excellent. We look forward to working with Trimline on future projects."

Undertaking the work while the ship was fully occupied and operational presented a challenging logistical refurbishment, limiting the nosiest work to periods when passengers were off the ship and carefully selecting material routes on-board to minimise the use of public areas. By working with the ships occupied cabin schedule, the team were able to work on deck without disruption to passengers and crew.

Simon Dawkins, Contracts Manager at Trimline, said: "We wanted to prove that large scale cabin refits do not have to be limited to docking periods. We faced a tough job whilst the ship was full of passengers, but the workforce almost became part of the crew. They spent so long onboard, sharing mess rooms and crew areas, that they developed a very good working relationship."

Gary Oliver, Managing Director of Trimline, commented: “Again this project demonstrates that with good communication between all stakeholders, large scale accommodation refurbishments can be undertaken successfully on the run whilst in service, instead of having to wait for sometimes years between dry dockings, thus keeping the vessel in tip top condition and meeting passenger expectations.”
