Mitsubishi Heavy Industries Marine Machinery & Engine (MHI-MME) will carry out a full-scale operation UEC35LSE and UEC33LSE which are the MHI-MME's most-advanced low speed marine diesel engines. Based on MHI-MME's market reserch, UEC35LSE and UEC33LSE engines are designed to provide the best suited output and rotation speed for a wide range of ships which are less than 30,000GT. The ships include bulker, chemical tankers, cement carriers and domestic vessels. Like the UE diesel engine, their high performance was confirmed by the onshore test, and also it has proved their fuel consumption exceeds competitor engines'. UEC35LSE was co-developed with Wartsila Corporation and UEC-35LSHthe engine has improved the reliability with the utilization of Wartsila's abundant know-how. UEC33LSE is the engine which has successfully improved the propellers propulsion efficiency by both long stroke and low speed engine, and it satisfies customers' needs of fuel savings. This UEC33LSE was downsized based on UEC35LSE to reduce the development period. The first UEC35LSE was consigned the manufactured to Kobe Diesel Co., Ltd, a licensee of UE engine, on August 2013. The engine was mounted on the cargo passenger ship named "Tachibana-Maru" built by the Mitsubishi Heavy Industries-Shimonoseki Shipyard & Machinery Works. This ship which is owned ...

CYE Petrol has chosen Emerson Process Management's Micro Motion Certified Bunker Measurement Solutions to enable accurate, transparent fuel deliveries from two new bunker barges being built in Turkey. The mass-based measurement solutions are Measuring Instrument Directive (MID) approved to meet international standards for custody transfer and will reduce measurement uncertainty that can lead to disputes or delayed vessel movements. "We want to be able to offer our customers a new level of accuracy," said Deniz Eraydin, general manager CYE Petrol. "The real-time and certified Heavy Fuel Oil and Marine Gas Oil bunker measurements provided by Emerson's Certified Bunker Measurement Solution will help improve our overall operational efficiency and raise customer confidence in the quality of our deliveries." Based in Istanbul, CYE Petrol is a physical bunker supplier, blending and distributing high quality fuels using a fleet of bunker barges and land-based tankers. The company supplies 15,000-20,000 metric tonnes of bunker per month to the Istanbul and Izmit bay areas as well as ports in the Black Sea and Sea of Marmara. Emerson's Certified Bunker Measurement Solutions will be installed on CYE's new KALAMIS-E and BEYKOZ-E, 1,650 deadweight tonne, double-hull bunker barges that are expected to be operational during autumn 2014. ...

ABB released third-party verification that its Onboard DC Grid helps vessels reduce their fuel consumption, cut noise and trim their environmental impact. The measurements and tests, conducted by Pon Power in collaboration with ABB on Myklebusthaug Offshore's platform supply vessel "Dina Star," identified reduction of specific fuel oil consumption of up to 27 percent. These are the first documented results from a vessel outfitted with ABB's Onboard DC Grid, which allows engines to run at variable speeds for top fuel efficiency at each load level. The tests also measured fuel consumption in dynamic positioning operations during challenging weather conditions, identifying fuel savings of 14 percent. Dynamic positioning operations, where computers automatically maintain a vessel's position and heading, account for a considerable portion of a typical offshore vessel's operational profile. "Our Onboard DC Grid is a significant step forward for electric propulsion. We are pleased that the concept delivered results that exceed our expectations", said Veli-Matti Reinikkala, head of ABB's Process Automation division. "Onboard DC Grid is a competitive advantage to ship owners operating a wide range of ship types from offshore vessels to ferries and yachts seeking to increase fuel efficiency and reduce emissions." In addition to fuel consumption, Pon ...

The UK P&I Club has issued a bulletin on technical problems and solutions of low-sulphur fuels. Typical technical problems experienced by shipowners when they are required to use low-sulphur fuels include issues with the supply and storage of low sulphur fuel, problems with machinery operation when using low-sulphur fuel, incompatibility between fuel types, and difficulties and delays when changing over from one fuel type to another. To avoid such problems, shipowners should consult their engine and boiler manufacturers for advice on operating with low-sulphur fuel and the need for any equipment and system modifications. Shipowners should also ensure that: all equipment including engines, purifiers, filters, fuel systems and sealing arrangements are correctly maintained fuel oil viscosity and temperature control equipment is accurate and fully operational system temperature and pressure alarms, fuel filter differential pressure transmitters and so on are accurate and operational. On each ship the fuel change-over procedure should be clearly defined and understood. Engineers need to be fully familiar with fuel systems and main engine starting systems and establish ‘failure to start' procedures. Starting air pressure should be monitored during manoeuvring operations and the deck department needs to appreciate the limitations of starting air availability. During standby, two ...

NAPA, global maritime software house, and ClassNK classification society announced that their comprehensive eco efficiency and operational optimization solution ClassNK-NAPA GREEN, has generated fuel savings of 3.9% on a "K" Line container vessel. The software solution was tested in full scale sea trials in January 2014 aboard an 8,000+ TEU container ship operating on a standard Mediterranean/Europe route. The full ClassNK-NAPA GREEN suite of systems were utilized on the voyage, including speed, trim, and voyage optimization based on the ClassNK-NAPA GREEN Dynamic Performance Model, and analyzed against the captain's voyage plan. Despite encountering heavy weather on multiple occasions over the course of the voyage, speed profile and voyage optimization reduced the fuel consumption by 2.7%, while a further 1.2% savings was attributed to optimum trim, taking the total reduction in fuel consumption from the trial to 3.8%. While trim optimization was restricted on this voyage due to loading conditions, results from a full-scale trim optimization study, conducted during two Indian Ocean crossings aboard the vessel, indicated that trim optimization has the possibility to further save fuel up to 4%. In addition it was found that the accuracy of Dynamic Performance Model - the self-learning component of ClassNK-NAPA GREEN - was ...

DNV GL has launched a new service named Build2Design to help shipyards and shipowners improve the fuel economy of their ships by reducing variations in their building process. Significant improvements have been achieved in the design of more fuel-efficient ships in recent years. The performance of these Eco-Ship designs has been documented by both Computational Fluid Dynamics (CFD) and tank testing and some designs have also proven their performance in operation. However, questions have been raised about variations in performance and research has now shown a wide variation in different ships of the same design. "We have compiled data that shows there is a large variation in fuel consumption between ships of the same design. This has led us to develop a new service, Build2Design, which aims at ensuring that the actual ship delivered is as good as its design," says Michael Aasland, Business Director for Bulk Carriers at DNV GL. Dr Olav Rognebakke, Head of Hydrodynamics at DNV GL, adds: "Build2Design is based on a solid theoretical foundation combined with the latest technology and uses advanced CFD calculations to identify the parameters that affect fuel consumption and the effect of each individual parameter." In developing the new service, DNV ...
