(Image: Wärtsilä)

Technology group Wärtsilä said it plans to introduce another four methanol engines to its portfolio. In addition to the Wärtsilä 32 methanol engine launched last year, Wärtsilä will add the Wärtsilä 20, Wärtsilä 31, Wärtsilä 46F and Wärtsilä 46TS, available for deliveries at different points from 2025 onward.Methanol is one of the primary alternative fuel choices for the shipping industry to achieve net zero carbon emissions by 2050. 'Green' methanol can be produced using renewable energy sources and carbon capture technology, making it a sustainable and carbon-neutral option.

A well-built, modern vessel can be expected to outlive her original engines. The challenge for those representing the owners, is to choose new engines that match or exceed the capabilities of the original power. Consideration will be given to replicas of the original engines. However, availability and suitability may limit this.These were some of the considerations confronting the Thai Marine Department when they decided to put their 41.85 by 3.9-meter oil response vessel back into service.

The Tampa Bay pilot association has returned its first Chesapeake Class pilot boat to Gladding-Hearn Shipbuilding. Tampa was built in 2003 when the shipyard introduced the class of mid-size, high-speed launches. In 2015, the Tampa pilots took delivery of the shipyard’s first Chesapeake Class MKII, which incorporates the performance benefits of Volvo Penta’s IPS 2 pod system. With more than 50,000 operating hours, the 53’ all-aluminum pilot boat will be repowered and undergo repairs after a thorough inspection by the shipyard’s quality control department.

The latest generation of mtu Series 4000 commercial marine engines for tugs, ferries and workboats will boast significantly extended engine running times of up to 96,000 hours between overhauls (TBO), according to manufacturer Rolls-Royce.In general, all marine engines of the latest generation of mtu Series 4000 can now run for up to 25 years before they need a major overhaul, depending on the duration and intensity of use, Rolls-Royce said. That is seven years more between overhauls than previously recommended.The new TBO intervals and maintenance schedules…

In continuously developing the range of services for its portfolio of four-stroke engines, MAN Energy Solutions enables its customers to exploit a multitude of synthetically manufactured, climate-neutral fuels in the operation of ships or power plants. Already today, MAN engines using power-to-X fuels such as synthetic natural gas (SNG) can be operated totally climate-neutrally.MAN customers will in due course be able to use other, so-called 'future fuels' –such as ammonia, methanol and hydrogen – also produced in a climate-neutral manner.

Seaspan Cavalier Repower: Long Life, Big Hours

(Photo: Alan Haig-Brown)

“We got 59,115 hours on those engines, without ever removing a head,” says Seaspan International’s Port Engineer Kevin Tweedy, “And they were still running. So, at 5,000 to 5,500 hours per year, we could easily have done 60,000 hours.”But the company schedule worked to do a like-for-like repower. The pair of 850-horsepower Tier 1 Cummins KTA38 diesels were pulled out, and a brand-new set of 850-horsepower Tier 2 KTA38s went in.The Seaspan Cavalier was built in 1974, along with three sister ships.

Built by Dakota Creek Industries in Anacortes, Wash., the first of the U.S. Navy's new fleet of six YT 808-class tugs was delivered in October after completing the last construction phase. Measuring 90 feet long and 38 feet 3 inches wide, the YT 808 vessel is powered by twin Cat 3512E marine engines, each rated at 1,810 horsepower. The engines drive two Schottel SRP 340 fixed-pitch z-drive thrusters providing a top speed of 12.5 knots and an expected bollard pull of 40 metric tons.The new series of Robert Allan Ltd.-designed tugs are the Navy's first vessels built to meet the U.S.

Since the days of wooden hulls and human power, lifeboat crews have put to sea through dangerous surf to save the lives of their fellow seamen. The first engine powered boats allowed decks and cabins that afforded a greater level of safety. When the U.S. Coast Guard developed its 47-foot surf boat in the late 1990s, a whole new standard for lifeboats was set.Designated 47-foot MLB, these all-aluminum craft demonstrated spectacular performance. Capable of handling 60-knots winds…

Opinion: Getting Ahead of the Reality

Frank Coles, CEO, Wallem Group

In a few short months, the mayhem wrought by coronavirus has changed the world. Our response to the epidemic [more than the virus itself] has the potential to permanently alter the balance of the global economy. But it might be the kind of Black Swan event that we need to trigger real change in the shipping industry – and in particular its approach to digitalization of vessel operation.Like the worldview bubbles created by social media algorithms and fake news, the maritime industry is living in its own digitalization fantasyland - one fueled by vendor delusion and media misinformation.

Repower of the Tug Gretchen H

(Photo: Mike Fourtner/Cummins)

As sometimes happens with boats in the maritime world, the recent repower of a tug shone a light on a pair of well known independent companies. The tug Gretchen H. (ex Harry Olsen, Polar Breeze) was built by Rodriguez Shipbuilding of Coden Alabama in 1997 and is currently owned, since 2005, by Boyer Towing.The Gretchen H is a good solid boat and her owners decided she was well worth a new set of engines. At 80 by 30 feet she has an eleven foot depth. As with many tugs out of the Rodriguez yard she has triple propellers and triple engines. She had an older set of engines rated at 700 HP each.

WinGD Intros New Short-Stroke Engines

Switzerland-headquartered developer of low-speed gas and diesel engines for marine propulsion Winterthur Gas & Diesel Ltd (WinGD) has launched four new short-stroke engines to address economic engine speeds and accommodate space constraints on several vessel types.The engine designer said in a press note that the range, starting with the X52-S2.0 and X62-S2.0 and their dual-fuel counterparts X52DF-S1.0 and X62DF-S1.0, feature a short piston stroke that is ideal for vessels with a shallow draught, small propeller diameter or low main deck height. Container feeders, ro-ro and con-ro vessels, multipurpose cargo vessels and vehicle carriers all have design conditions that demand a shorter stroke.

SC Ports, DHEC Get Grant for Crane Tech

South Carolina Ports Authority (SCPA) and the South Carolina Department of Health and Environmental Control (DHEC) were awarded a $2 million grant from the U.S. Environmental Protection Agency’s Diesel Emissions Reduction Act (DERA) grant program to upgrade the engines of 12 rubber-tired gantry (RTG) cranes.The EPA awarded the grant to DHEC, in partnership with SCPA. The funding will equip the Port’s RTG cranes with hybrid battery/genset engine systems, replacing the existing hi-power diesel engines.The new engines will reduce emissions of particulate matter, air toxins and nitrogen oxides up to 96% while reducing annual fuel consumption by over 100,000 gallons.SCPA Chief Operating Officer Barbara Melvin said S.C.
