STCW Falls Short on Ammonia Training
Lloyd’s Register's Maritime Decarbonisation Hub (The Decarb Hub) and Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) have released a third report aimed at helping meet the upskilling needs of an estimated future 800,000 seafarers as the industry transitions to alternative fuels.While current frameworks outlined in the IMO STCW for seafarer training provide a foundation, they fall short of addressing the unique challenges posed by ammonia, says the organizations…
Ammonia Advances
Taking a well-to-wake approach to CO2 emissions means that the shipping industry will look beyond emerging engine technologies such as dual-fuel ammonia engines when considering the viability of alternative fuels.Engine manufacturers are optimizing combustion and reducing pilot fuel requirements, but any pilot diesel requirements mean the process is not 100% carbon free.This week, Hanwha Power Systems, Hanwha Ocean and Baker Hughes announced a different concept. The companies agreed to design and produce low carbon ammonia gas turbines capable of 100% ammonia combustion.
Maritime Industry's Fuel Quality Issues Persist
Ongoing concerns around fuel quality continue to be a critical factor and significant expense for the maritime industry, according to the Lloyd’s Register (LR) Fuel Quality Report 2024.The report, produced by LR’s Fuel Oil Bunker Analysis and Advisory Service (FOBAS), reveals the overall state of fuel quality in 2024 remains much like that of the past few years, particularly since the transition to predominantly very low sulphur fuel oil (VLSFO) in 2020. Persistent issues such as cat-fines…
Amogy's Ammonia-powered Tugboat Sets Sail
A 67-year-old tugboat converted to run on Amogy's cleaner-burning ammonia-to-power technology has set sail for the first time in upstate New York.The 105-foot tug, originally built in 1957 and recently renamed NH3 Kraken, is the first vessel globally fitted with the innovative, carbon-free power system, developed by Amogy to reduce emissions from hard to abate sectors such as maritime.The conversion project was carried out at Feeney Shipyard in Kingston, N.Y. and involved a comprehensive overhaul of the tugboat's original diesel generators and electric motors…
Becker Marine Systems Introduces New Wind-Assist Steering Technology
Becker Marine Systems introduced two new products at SMM which are designed to optimise vessel hydrodynamic performance: the Becker Daggerboard and the Becker Steering Gear.The Becker Daggerboard is an anti-leeway fin designed for ships equipped with modern wind- assisted propulsion systems (WAPS). When using WAPS, the desired thrust ahead components drive the ship. Depending on the wind direction, there can also be stronger or weaker lateral force components leading to leeway from the desired course.
Study Evaluates Uses for Batteries on Deep-Sea Vessels
Industry group CIMAC and the Maritime Battery Forum have published the first of three white papers on the use of batteries in deep-sea shipping.This first paper, Environment for the use of batteries in deep-sea shipping: Use cases and application areas, demonstrates the potential for battery usage even though a fully battery-powered, zero-emission application is not yet available.Currently, vessels on order include hybrid propulsion vehicle carriers and oil/chemical tankers. Installations typically vary between 350kWh and 2,847 kWh.
WE Tech Solutions to Supply Hybrid Electric System for Sirius’ New Chemical Tankers
WE Tech Solutions informs it has received an order from Sirius Shipping for a hybrid electric system for their new chemical tankers. For this order, WE Tech Solutions will provide the Solution Four for the tanker pair. This solution is based on a battery hybrid shaft generator solution. The solution makes it possible to run the main motor at variable speed, and the propulsion machinery can be operated at optimal duty points at all vessel speeds. The electrical network is also generated by the shaft generator. Therefore, there is no need to run auxiliary engines and generators when sailing.
Alternative Fuels: Many Possibilities But a Clear Path is Evasive
“It was the best of times, it was somewhat confusing times, it was the age of wisdom, it was the age of the learning curve, it was the season of light, it was the season of, uh, still not enough light.” ― Deepest apologies to Charles Dickens, A Tale of Two Cities, 1859As the world zeroes in on alternative energy sources and products that can deliver power and performance, there are advances that could sway even the most hardened skeptic. But challenges remain—tough challenges.Two successes: renewable diesel and biodieselRenewable diesel (RD) is required now (since January 1…

The use of a vessel plying short-sea routes will allow regular access to fuels stored onboard for sampling and testing during frequent port calls.FAME…
Flawed Propeller Blade Caused Containership to Lose of Propulsion -NTSB
A containership transiting the Pacific Ocean lost hydraulic oil and propulsion after its propeller blade cracked, according to a report from the National Transportation Safety Board (NTSB). A blade on the vessel’s controllable pitch propeller system did not meet manufacturer design specifications, the investigation found.The Matson containership Maunalei was travelling to Portland, Ore., from Anchorage, Alaska on August 11, 2022, for drydock repairs when the crew intentionally shut down the main engine due to problems in the controllable pitch propeller system…
