Shipping Company Cassen Eils, Cuxhaven, part of AG Ems shipping company, has charged shipyard Fassmer GmbH, Berne, to build a new innovative ferry which is intended to do service between Cuxhaven, maybe also Hamburg, and the Island of Helgoland. It is the first new build of the company which will feature natural gas propulsion. The new ferry features a special designed hull, with this the vessel will have very special sea-keeping characteristics. The ships length is of 79,90 m, it’s width is of 12,40 m and the depth is of 3,60 m. A dynamical stabilizer system supports comfort on board the vessel. The still existing HELGOLAND will be taken out of service in 2015 when the "Green Ship" with gas propulsion is ready The ship can carry 1.000 passengers. The state-of-the-art passenger area features an open atrium with a glass elevator, several decks, large gastronomy, spacious sun-decks and a sky-bar. A Cargo compartment carries cargo of all kinds. Additional cargo space allows up to t... [More]

The Future of the Fehmarn Link: ZERO EMISSION SHIPS

GL subsidiary FutureShip has developed a zero-emission propulsion concept for shipping company Scandlines. This trailblazing technology will be implemented on the Baltic ferries within the next five years.In the world of international container shipping, “slow steaming” has long become widespread practice. With the optimization of hulls and innovative designs, FutureShip played an appreciable role in the successful implementation of the concept. Together with shipping company Scandlines, this subsidiary of GL is going one step further: the development of double-ended ferries that are totally emission-free. The FutureShip engineers took a completely new course and approached the matter in a holistic way: from fuel-protection, through energy conversion and storage, and up to optimization of the ship design. For example, the surplus electricity generated by wind turbines in northern Germany and Denmark is to be used to produce hydrogen. This can be transformed back into electr... [More]

Joint Study by MAN and GL on LNG as a Fuel for Container Ships

MAN Diesel & Turbo together with Germanischer Lloyd have published a study analyzing the problem of the best way for container ships to meet the present and future exhaust emission regulations. The four technologies investigated in the study are: exhaust gas cleaning by scrubber, scrubber plus Waste Heat Recovery (WHR), LNG as a fuel and LNG with WHR. In the study, circumstances were considered for five sizes of container ship. The smallest is a feeder of 2,500 TEU going up to the largest of 18,000 TEU. For each ship size the speed, engine power, round trip distance and percentage of distance spent in Emission Control Areas is estimated proportionally. The study concludes that LNG offers lower emissions and given the right circumstances, less fuel cost. [More]

First conversion to LNG completed

The product tanker MV Bit Viking has completed the first ever conversion worldwide, of a vessel from HFO to LNG and is now in service operating along the Norwegian coastline . The very low emissions now attainable will qualify for lower Norwegian NOx emission taxes. The Bit Viking has a very high safety specification, delivered in 2007, the double hulled product tanker of 24,783 dwt has an LOA of 580 ft (177 m) and a beam of 82 ft (26.3 m). The conversion required a major rebuild of the engines from Wärtsilä 6L46B to 6L50DF engines with output of 7,460 hp (5,700 kW). Although having the same stroke as the old engine, required increasing the cylinder bores from 460 mm to 500 mm and replacing most of the engine parts. Safety analysis and approval was undertaken by Germanischer Lloyd (GL) classification society. [More]

Fuel Cell Vessel Back In Service

The 100 passenger Hamburg, Germany tourist vessel Alsterwasser is back in service after refurbishment following a devastating fire last year. The hydrogen fueled vessel has two 50 kW (67 hp) fuel cells powering a100kW (134 hp) hybrid electric propulsion system with lead acid batteries. The vessel was built in 2007 and entered service in 2008. The hull has an LOA of 25.5 m (84 ft), beam 5.2 m (17 ft), a draft (laden) of 1.3 m (4.2 ft) and displacement of 72 tonnes (79 tons). The maximum height of 2.6 m (8.5 ft) can be reduced to 2.3 m (7.5 ft) by lowering the cabin roof to allow passage under low bridges. The ship including fuel cell propulsion system is classified by Germanischer Lloyd. The hydrogen is sufficient for three days power supply, refueling takes approximately 12 minutes. The annual nett benefit to the environment is a saving of 1,000 kg of NOx (1.1 tons), 220 kg (485 lbs) SOx, 40 g (1.4 oz) of particulate and 70 tonnes (77 tons) of CO2. [More]
