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]
The worldwide first with Methanol powered vessels will navigate with DNV GL Class the classification society announced recently.
The four 50.000 tdw tanker have been ordered by the Swedish shipping company Marinvest and the Norwegian company Westfal-Larsen at the Korean shipyard Hyundai Mipo Dockyards. The classification follows according the DNV GL regulation for fuels with low flashpoint. The very first tank ship shall be delivered by 2016.DNV GL says the sulfur free fuel with low flashpoint (Low Flashpoint, LFL) of about twelve degrees Celsius becomes more and more attractive for the maritime industry, because this fuel fulfills the upcoming SOx-limit values in the emission control areas.The vessels, which will carry the additional DNV GL mark LFL FUELLED, feature a secondary bunker system as well as an automatically leakage warning system with shot-off function and flame protection systems. Further building safety measures include the position of the tanks and fuel pipes.

After transfer from Southampton service as a hotel vessel at the “Super Bowl” in New York – First cruises in the Caribbean
During a ceremony at the beginning of January 2014 in Bremerhaven, Norwegian Cruise Line took delivery of the 145,655 gross ton cruise ship Norwegian Getaway from MEYER WERFT after a building period of only 15 months. The ship, the second of two Breakaway Class ships, is being delivered just nine months after the launch of sister-ship Norwegian Breakaway. Following delivery today, the ship is sailing to Rotterdam for the start of inaugural festivities which will continue in Southampton before the ship departs for her transatlantic cruise to New York. The ship will be christened in Miami on February 7.The cruise liner starts the first transfer from Southampton to New York with around 1.500 crew members from over 60 nations. In New York the vessel will act as a hotel ship for the super event “Super bowl”. After the christening ceremony i... [More]
At slow steaming cold corrosion can occur – Castrol sees concerns by specifications given from the engine manufacturers confirmed.
Many shipping owners go for slow steaming. But to avoid long term damages by slow steaming particular adjustments must be done. One aspect is the use of optimized lubricating oils. A possible problem is cold corrosion. The lubricating oil manufacturer, e.g., Castrol Marine assumes that, during slow steaming, cold corrosion can happen if lube oils with lower base numbers (BN) come together with fuels with higher sulphur content. “We always point out that oils with lower BN are unsuitable for slow steaming with modern diesel engines. Both market leading OEM’s have now created specific guide lines, which go along with our experiences”, says Castrol manager Paul Harrold. They recommend their customers to coordinate the use of lube oils with engine type and working conditions. Last May Castrol presented some case studies. These figures un... [More]
TOTE’s 3,100TEU container ships, the world’s first Natural Gas-fuelled boxships, will be powered by MAN ME-GI engines with DSME’s HP-FGS technology
Daewoo Shipbuilding & Marine Engineering has announced a patent license agreement with MAN Diesel & Turbo for use of the DSME high pressure-fuelled gas supply (HP-FGS) system.
Under the terms of the contract, details of which are being kept confidential, MAN will use DSME’s HP-FGS system patents and licenses for its two-stroke Natural Gas propulsion based commercial vessel projects.
DSME believes this to be a significant development in gas fuelled ship technology, as with a claimed 80% market share, MAN Diesel & Turbo enjoys a leading position in large two-stroke marine engines. As the first orders for two-stroke marine engines using Natural Gas fuel have been for MAN’s ME-GI engines, DSME says that “this patent contract is expected to bring out great ripple effects to related industries...

The multi-functional construction and pipelay vessel Ceona Amazon, which will be built by Lloyd Werft Bremerhaven AG for the British operator Ceona, will be equipped with two 9L32/44CR engines and four 8L32/44CR main gensets, providing a total output of 28MW. This was recently announced by MAN Diesel & Turbo who had won the order.
Based on a drill-ship design, the 33,000gt, 199.4m-long and 32.2m-wide Ceona Amazon boasts exceptional sea-keeping characteristics, making it ideal for operations in remote and challenging locations, the engine manufacturer noted.
The construction vessel has a large, under-deck storage capacity for line pipe or umbilicals, together with a large deck area that allows the further storage of line pipe and standard, flexible installation reels.
It is fitted with two heave-compensated mast-head cranes, and a single heave-compensated knuckleboom crane. The pipelay system consists of an inclinedlay system and a rigid, pipeline firing-line system. The vess... [More]
It’s not a secret anymore that the shipping industry today is facing some serious challenges with respect to meeting upcoming exhaust gas emissions regulations. The contribution from shipping to sulphur oxide (SOx) and nitrogen oxide (NOx) emissions today is considerable, thus the need for reductions. Three main alternatives – switching to low-sulphur fuels, installing exhaust after-treatment devices, e.g. scrubbers, or using natural gas – have been investigated to some extent, but very little information is available on methanol as a marine fuel.Methanol is a clean fuelMethanol does not contain sulphur. Emissions of particulate matter and NOx from methanol combustion in marine engines are expected to be lower than those resulting from the combustion of conventional fuels. Methanol is widely available, can be safely transported and distributed using existing infrastructure, and in 2012 it is currently much cheaper than marine distillate fuel based on energy content. I... [More]
80-ton bollard pull vessels ready for anchor handling tug supply services
MAN Diesel & Turbo’s medium-speed propulsion packages have gained another foothold in Middle Eastern offshore operations. After successfully completed sea trials, Abu Dhabi-based Adyard has earlier delivered the ‘Topaz Dignity’ – which is now followed by the ‘Topaz Triumph’ AHTS. Topaz Energy and Marine, a subsidiary of Oman-based Renaissance Services SAOG and a regional leader in providing offshore support vessels and engineering services, has passed yet another milestone in its 35-year history by building two Anchor Handling Tug Supply vessels.
The two 67-metre, ’80-ton bollard pull’ vessels are ready for anchor handling tug supply services and the transportation of dry and liquid cargo to and from pipe-laying barges, drilling platforms and production... [More]
