The propulsion engines and generator sets for the power supply of the three new Miecznik multipurpose frigates for the Polish Navy are currently being built at the Rolls-Royce Power Systems Division in Friedrichshafen. Four 20-cylinder mtu Series 8000 engines with 8,200 kW each and four 12-cylinder mtu Series 4000 gensets with 1650 kW mechanical power each will be installed on each ship. The CODAD (combined diesel and diesel) propulsion system consists of two engines per shaft/propeller and can be used flexibly in different combinations - from single engine operation for slow patrols to high-speed operation at over 20 knots (37 km/h) with all four engines. With a cruising speed of...

New water reservoir planned for the Panama Canal

New water reservoir planned for the Panama Canal

Posted by | 18 Jul 2024 | , , , | 0

The Panama Canal Authority (ACP) is planning to build a new additional water reservoir to ensure the maximum passage of 36 ships per day even during periods of drought. The Indio River Reservoir project would become part of the existing artificial lakes and feed Lake Gatun, as well as providing a little more safety and a higher level of reliability for the route and the drinking water supply for the population. A law passed in 2006 previously prohibited the construction of additional water reservoirs outside of the country's own water catchment area. The Supreme Court of Panama has now authorised the construction of the new reservoir in order to increase water availability. To ensure that the project in the catchment area of the...

Onshore or offshore - wood can be used anywhere

Onshore or offshore - wood can be used anywhere

Wind turbine blades made of wood offer a sustainable option, the Hessian start-up (2021) Voodin Blade Technology is convinced and has installed the world's first prototype installation of its wind turbine blades made of 100% biodegradable wood, which are over 19 metres long, at an existing wind turbine in Breuna, north-west of Kassel. After two years of thorough laboratory testing, the Voodin team is confident that the material will withstand even the harshest onshore conditions. They also see no reason why their rotor blades could not be used offshore. The company said that the use of laminated veneer lumber is more sustainable and durable than the commonly used glass fibre reinforced plastics (GRP), which become brittle after years of use.

Hamburg - Hapag-Lloyd CEO thinks out loud about nuclear propulsion

The world's fifth-largest shipping company has committed to reducing its absolute greenhouse gas emissions by around a third by 2030 and to net-zero fleet operations by 2045. This is to be achieved through the modernisation of the fleet, new drive technologies and the research and procurement of CO2-neutral alternative fuels (e-fuels), such as "green" methanol. Hapag-Lloyd has been modernising and expanding its fleet for years. A total of 12 new large container ships have been ordered (see marineforum.online from 23 June 2021), which can be operated with modern and efficient high-pressure dual-fuel engines and are already in service. A study is also currently considering "sailing container ships" with methanol engines (see marineforum.online from 18 December 2023). In order to reduce fuel costs and...

Rügen: Green light for gas pipeline - court rejects lawsuits

Rügen: Green light for gas pipeline - court rejects lawsuits

Posted by | 9 Jul 2024 | , , , | 0

The Federal Administrative Court in Leipzig has dismissed several appeals by Deutsche Umwelthilfe (DUH) and the Nature and Biodiversity Conservation Union (NABU) against the operating licence for the gas pipeline between the port of Mukran and Lubmin. This means that the approximately 50-kilometre-long gas pipeline operated by Gascade, which connects the LNG terminal in Sassnitz-Mukran to the gas pipeline network in Lubmin to the east of Greifswald, is expected to go into operation as planned in mid-May. Specifically, the environmental organisations wanted the planning approval decision issued by the Stralsund Mining Authority last year to be revoked. They had criticised the pipeline on two points in particular: firstly, nature conservation concerns in the sensitive ecosystem of the Greifswald Bodden were not taken into...
