Caterpillar Marine will launch the Cat Propulsion Twin Fin System at the 2014 ITS Hamburg Conference and Exhibition, June 16th - 20th. The Cat Propulsion Twin Fin System is a new diesel-electric solution that saves on fuel and emissions, while improving overall vessel performance. The Twin Fin System protects all of the propulsion mechanical parts within the hull profile while retaining the cargo space saving and maneuverability claims made for outboard solutions while simultaneously offering critical reliability gains. Initially conceived for harsh operating environments, the Cat Propulsion Twin Fin System comprises a compact electric motor and gearbox configuration connected via short drive shaft, rotating a pair of controllable pitch propellers whose performance is enhanced by two tailor-made fins attached to the hull. Major transmission parts in the system are accessible from inside the vessel, enhancing ease of maintenance and averting the need to drydock. The Twin Fin solution can be applied to newbuilds, retrofits and conversions in any commercial marine application and is available via the global Cat dealer network. "We developed the Twin Fin system in partnership with Odense Maritime Technology (OMT) and Scandinavian Marine Group (SMG) initially as a solution to make vessels operating in Arctic conditions less ...

In comparison to ...

Tsuneishi Shipbuilding has brought to market the TESS64 AEROLINE, a D/W 63,700mt type Bulk Carrier that is equipped with the new AEROLINE technology to reduce wind resistance. AEROLINE is a new technology for reducing wind resistance, which combines the cut-corner design for the accommodation corner in previous models with a newly developed streamlined shape for the fore upper bow, for a 10% reduction in wind resistance. The fore upper bow has been rounded, giving the ship a stylish streamlined design. While nearly covering the navigation patterns of the TESS58 vessels, which are the largest in the TESS : Tsuneishi Economical Standard Ship, HANDYMAX Series of over 300 ships built so far, this new model is 10 meters longer, which enables a boost in deadweight to the 60,000-ton class for improved transport efficiency. Sales of these new ships have begun, as Tsuneishi Shipbuilding's first D/W 63,700mt type Bulk Carrier that were developed with environmental friendly shallow draft.

Exhaust Gas Recirculation (EGR) has firmly shown its ability to comply with Tier III NOx limits, which will enter into force in January 2016. Over 1000 hours of EGR operation have now been achieved aboard the Maersk Cardiff, a container newbuild from A.P. Moller-Maersk with a two-stroke MAN B&W 6S80ME-C9 engine. Developed by MAN Diesel & Turbo, the EGR process already relies on Alfa Laval's PureNOx, which provides the vital cleaning of the scrubber water. Now Alfa Laval is cooperating with MAN Diesel & Turbo to implement an EGR boiler, which could potentially add major energy benefits to the secure emission compliance. Having demonstrated reliable compliance with Tier III NOx legislation, as well as the potential for fuel savings in Tier II operation, the vessel's EGR installation will soon be expanded with another remarkable technology: a pressurized EGR boiler from Alfa Laval. "We have shown that EGR works smoothly and that it complies fully with the NOx limits appearing in 2016," says Michael Witt, Head of Retrofit Development R&D at MAN Diesel & Turbo. "Together with Alfa Laval and A.P. Moller-Maersk, we are now looking beyond compliance to optimize the system and to utilize opportunities for energy savings." The reasons ...

Rolls-Royce has installed the innovative Promas Lite propulsion system on SuperStar Virgo, the first vessel in South East Asia to be equipped with this efficient and fuel saving system. Promas Lite is an integrated propeller and rudder system that increases efficiency and is designed specifically for retrofitting to existing ships. Norwegian Spirit operated by Star Cruises' subsidiary Norwegian Cruise Line was the first vessel in the fleet to be installed with Promas Lite in 2011. The efficiency gains and fuel saving benefits from the first upgrade has resulted in this subsequent order from Star Cruises. Andrew Marsh, Rolls-Royce, President - Services said: "We highly appreciate the trust given to us by Star Cruises through this second order. As Asia Pacific's leading cruise operator, they recognise that using the Promas Lite solution will substantially reduce emissions and the operating costs of SuperStar Virgo." Typical fuel savings for Promas Lite range from 5 to 15 per cent, depending on the type of operation and the performance of the existing propeller. A cruise ship like SuperStar Virgo can expect to generate £800,000 annually in fuel savings and a corresponding CO2 emission reduction of around 4,000 tonnes per year by converting to Promas Lite. ...

Rolls-Royce has been contracted to install its innovative Promas Lite propulsion system on four Finnlines ships, all to be delivered later this year. Promas Lite is an integrated propeller and rudder system that increases efficiency and is designed specifically for retrofitting to existing ships. Finnlines is part of the Grimaldi Group, which has over three years of experience with Rolls-Royce on a series of projects to re-blade propellers to improve efficiency. The efficiency gains and fuel saving benefits created by these projects has led to this latest contract to equip four Finnlines vessels. In many previous Promas Lite upgrades, the primary goal has been to achieve fuel savings for the customer. Finnlines, however, wished to maximise the efficiency of its vessels while also ensuring the new engine configuration maintained the speeds required on its routes. Successfully striking this balance was key to securing the £3.8m order. Andrew Marsh, Rolls-Royce, President - Services said: "We are delighted to work together with Finnlines to bring the first installation of Promas Lite to the Baltic Sea. Not only will Finnlines achieve a reduction in fuel consumption but also in NOx emissions, helping the company realise its environmental ambitions." Typical fuel savings for Promas ...

AkzoNobel's Marine Coatings business, and The Gold Standard Foundation have announced a new and unique methodology to reward the improved fuel efficiency of ships within the international maritime industry. Certification by The Gold Standard for the first of its kind, peer-reviewed methodology will allow ships to generate carbon credits, thus income, for the CO2 emission reductions they achieve. The methodology is based on ship owners and operators converting existing vessels from a biocidal antifouling system to the premium, biocide-free advanced hull coating Intersleek. A baseline emission level is determined for the vessel prior to the application of Intersleek with the same data source then used to determine the emission savings after the application of Intersleek. The carbon credits generated are directly related to reduced emissions as a result of reduced fuel consumption. "This landmark methodology enables ship owners and operators to benefit twice when they invest in Intersleek technology. Firstly, they can increase operational, environmental and energy efficiencies, which reduces fuel costs and emissions and then they can reap the additional financial benefits of carbon credits, which we will share with them," says Trevor Solomon, Intersleek Business Manager. Added Conrad Keijzer, AkzoNobel's Executive Committee member responsible for Performance Coatings: "This ...

Mitsubishi Heavy Industries (MHI) and Mitsubishi Kakoki Kaisha (MKK) have jointly developed a "Hybrid SOx Scrubber System" that efficiently removes sulfur oxides (SOx) from exhaust gas emitted by marine diesel engines. The Hybrid SOx Scrubber System is the first in Japan to comply with the more stringent SOx emission regulations that will take effect in designated emission control areas (ECA) in 2015. The system is capable of scrubbing exhaust gas from the combustion of fuels emitted from bunker heavy fuel oil to the level combusting more costly low-sulfur fuel oil. By adopting a modular design, the system also facilitates retrofit installations on ships already in service. The Hybrid SOx Scrubber System has two scrubbing system: one that uses circulating with freshwater and the other uses one-pass flow with seawater. Removal of atmospheric pollutants can be effected by either system. The freshwater system is capable of scrubbing exhaust gas from combustions of heavy fuel oil with 3.5% sulfur content to that of low-sulfur fuel oil with 0.1% sulfur content, achieving compliance with SOx emission regulations of IMO (International Maritime Organization) scheduled to go into effect in ECA in 2015. The seawater system is capable of scrubbing exhaust to a level of ...
