The biggest, most powerful dual-fuel engine ever built has received type approval.
Bureau Veritas certified Winterthur Gas & Diesel’s (WinGD) 12X92DF engines, the first series of which is being built by China State Shipbuilding Corp and will power nine ultra-large container ships owned by CMA CGM Group.
The type approval was awarded following a series of full-load tests in diesel and gas operation.
Klaus Heim, CEO of WinGD, said, “With the type approval of our biggest engines to date, we are opening up the possibilities of LNG-fueled ship propulsion to yet another vessel segment, a testament to its cost-efficiency, reliability and sustainability.”
Dominik Schneiter, vice president for research and development at WinGD, added that the engine outperformed expectations for NOx, SOx and PM emissions.
Wind propulsion systems provider Norsepower installed its Rotor Sail Solution to a Scandlines hybrid ferry in a matter of hours during a scheduled overnight stop.
The rotor sail is estimated to reduce emissions by 5% without compromising speed or voyage times.
The unit was fitted to M/V Copenhagen in the German port of Rostock. It is 30m tall and 5m in diameter, and can be installed in new vessels or retrofitted.
It is a modernized version of the Flettner rotor, a spinning cylinder using the Magnus effect to harness wind power to move the ship.
Seven companies in Japan have joined forces to establish the e5 Consortium to create zero-emission electric vessels.
The seven companies are Asahi Tanker, Idemitsu Kosan, Exeno Yamamizu, Mitsui O.S.K. Lines, Tokio Marine & Nichido Fire Insurance, Tokyo Electric Power Company and Mitsubishi Corporation.
In the first phase of the project, the partners plan to launch the world’s first zero-emission electric tanker powered by lithium-ion batteries in March 2022.
The five values of e5 are electrification, environment, evolution, efficiency and economics. The consortium says it wants to promote sustainable growth of coastal shipping in Japan.
Tornado Boats has introduced the climate neutral 6m ZERO-E coach boat, which is powered by Torqueedo’s Deep Blue Blue 50R outboard and features a 40 kWh Deep Blue battery.
The coach boat for sailing clubs was launched in response to World Sailing’s Challenge 2024, which asks competitors to halve the number of combustion-powered coach boats at Olympic Class events by 2024 and eliminate fossil fuel-powered official boats by 2025.
Lars Hjorth, owner of rigid inflatable boat (RIB) manufacturer Tornado Boats, explained the story behind the vessel’s creation: “I started looking into building an electric coach boat about three years ago, but thought the price was too high for the market at the time.
Japan is to build its first LNG-fueled ferries. The ships, which will be built for Ferry Sunflower at Mitsubishi’s Shimonoseki shipyard, will have an LNG package consisting of a Wärtsilä 31DF engine, gearbox and LNGPac storage, supply and control system. The project has been adapted for Japan’s energy-conservation rating system for coastal ships.
Keisuke Yasutake, area sales manager Wärtsilä Japan, said the 200-meter-long ships, known as ‘Sunflower Kurenai’ and ‘Sunflower Murasaki,’ will have the capacity to carry 763 passengers, 136 trucks and 100 passengers at a speed of 22.5 knots.
The Kongsberg Maritime-designed freezer trawler known as ‘Ilivileq’ has entered service in Arctic waters.
Ilivileq uses a hybrid-propulsion system which Kongsberg says allows the captain to select operational modes from the bridge panel and monitor the fuel consumption in each mode.
The hybrid system runs the engine and propeller at variable rpm (combinator mode) following what is claimed to be the optimal propeller curve. The unit reduces fuel consumption by reducing the pitch loss that fixed rpm propulsion systems have, especially when operating in modes requiring low load on the propeller. In combinator mode, the hybrid shaft generator works with an AFE drive that secures constant fixed frequency to main switchboard and suppliers.
Electric power systems similar to those used on the road are helping marine operators cut emissions and save on fuel and maintenance costs.
San Francisco Bay sightseeing company Red & White Fleet has been using BAE Systems’ HybriGen power system in its vessel Enhydra.
The electric-hybrid technology, which Red & White has used since 2018, has resulted in fuel savings of 35% for the 128ft excursion vessel by only using its combustion engine some of the time.
Other operators are beginning to use the electric-hybrid technology, including Kitsap Transit on its passenger ferry Waterman in Port Orchard, Washington state, and Call of the Sea in San Francisco, California, which is using the technology to power a 132ft ship teaching young people about maritime history.
Oxis Energy and Minas Gerais Development Company (CODEMGE) have taken possession of a battery plant in Brazil.
The two companies signed a 15-year lease deal with Mercedes Benz Brazil for the plant located at its manufacturing site in Juiz de Fora in the state of Minas Gerais.
Nordika Pharmaceutical will manage the design and engineering of the plant and machinery layout.
Upgrades will start immediately and involve investing over US$50m to have the plant fully digitized and operating by 2023.
Phase 1 will cover 20,000m2 to produce five million lithium sulfur cells per year with the option to expand and double the estate and cell capacity.
