Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency
It is easy to appreciate why permanent magnet synchronous motors (PMSMs) are popular for use in underwater vehicles (UVs). They are compact and efficient with a high power density. More importantly, perhaps, they allow for effective operation across a broad RPM range which is beneficial for vehicles with multiple operating conditions. That said, we find vehicle product developers are often uncertain about a motor’s “efficiency”. This article offers a few comments from the perspective of a propeller designer…
AAM Takes Over Hydrogen Ferry New Build
All American Marine, Inc. (AAM) won a contract by SWITCH Maritime (SW/TCH) to complete the aluminum construction and outfitting of a 70-foot 84-passenger zero-emissions, hydrogen-powered, electric drive ferry that will operate in the California Bay Area (referred to as the ‘Water-Go-Round’ project).Prior to transfer to AAM, the project had begun at Bay Ship & Yacht shipyard in Alameda, Calif. where the aluminum hull and superstructure had been started.

Corvus Energy Invests in Canadian Battery Production
Corvus Energy is moving forward with plans to invest in its Canadian operations by expanding its Richmond, B.C. facility and increasing manufacturing capacity.As reported in early 2018, Corvus Energy is rolling out plans for expanded maritime battery manufacturing facilities in both Bergen, Norway and Richmond, B.C., Canada. A new automated battery factory in Bergen began producing energy storage systems (ESS) in Q4 2019. Corvus has signed a contract for investment in new production line equipment in the Richmond, B.C.
New Combined Separator for EGR and Bilge
Marinfloc has introduced its combined Exhaust Gas Recirculation Bleed Off water treatment system and Bilge water separator. The solution is approved by both DNV GL and MAN Energy Solutions and fulfills the requirements of MEPC 107(49) and MEPC 307(73). The approval means that only one separator is required instead of two. Reducing the amount of equipment needed on a vessel will provide shipyards, engine makers and ship owners with a significant cost saving solution. Exhaust Gas Recirculation (EGR) is used to reduce NOx as per the Tier III requirements when use with compliant fuel.
EPA Tier 4: Difficult and Contentious, 12 Years and Counting
When it comes to complying with EPA’s Tier 4 emissions regulations, there’s no shortage of creativity emerging from America’s maritime engineering firms. Companies such as Hug Engineering are offering flexible, customized aftertreatment-based control systems that can assemble almost in modular like fashion. Other companies, such as ABB Group, offer battery-hybrid power sources to complement combustion power and avoid threshold diesel emissions. Engine manufacturers, such as Cummins…
Wärtsilä Testing Ammonia as a Marine Fuel
As marine operators and euipment manufacturers continue to explore alternative marine fuels as a means to help lower vessel emissions, technology group Wärtsilä said it has initiated combustion trials using ammonia.As part of the tests, ammonia was injected into a combustion research unit to better understand its properties. Based on initial results, the tests will be continued on both dual-fuel and spark-ignited gas engines. These will be followed by field tests in collaboration with ship owners from 2022…
Chevron Marine Launches Digital Platform
Fuels and lubricants supplier Chevron Marine launched a suite of digital solutions offering ship owners and operators tools with which to analyze, manage and ultimately help to improve their operational performance.Chevron Marine Cloud Solutions, including the customer order management platform OnePort launched last year, were developed under Chevron’s Business Technology Innovation (BTI) initiative as part of an ongoing, multi-year digitization investment program. The solutions are designed to integrate with customers’ processes…
Total Lubmarine's Talusia Universal Gains NOL from WinGD
Total Lubmarine’s Talusia Universal (BN57) has received a No Objection Letter (NOL) from WinGD for all fuels (liquid and gas) with a sulphur content 0.00%S - 1.50%S.The NOL was awarded with no restrictions following the successful completion of two rigorous tests carried out on two different vessels fitted with W6X72 engines.The tests were conducted on split engines comparing Talusia Universal with a BN40 reference Cylinder Lube Oil (CLO). One test carried out with compliant VLSFO <0.5%S…
Staten Island Ferries: A "New York State of Mind"
It takes a thick skin to live in New York City, let alone to run its Staten Island Ferry service. James C. DeSimone, Deputy Commissioner, Ferry Division, New York City Department of Transportation, has been charged with running the ferry service for the last 16 years. We met with him for his insights on the challenges of keeping the iconic ferry running safely and efficiently.Jim DeSimone has led a maritime life, with his time equally split between the private and public sectors. His maritime affiliation is literally in his blood, as his father Guy J.
Rewrite the Rules: The Path to Zero Emissions
With social media updates and conference agendas addressing the subjects of climate change, emissions reductions and alternative fuels, it’s a wonder we are not climbing the Himalayans in search of the Jedi Master that will provide us with the magic potion. Yoda’s blessing with a calming breath, “You have chosen wisely.”Government emissions intervention started with a move to reduce energy and fuel consumption measured in greenhouse gas (GHG), at a time when the world and our politicians spoke about global warming.

Research Vessel Atair to be Commissioned this Spring
A new liquefied natural gas (LNG) powered survey, wreck-search and research vessel built by German Naval Yards Kiel is currently undergoing installation and finishing works at Fassmer in Berne, Germany prior to being commissioned this spring.Ordered by the German Federal Maritime and Hydrographic Agency (BSH), the new research vessel will be homeported in Hamburg, replacing the previous Atair, which entered operation in 1987.At 75 meters long and roughly 17 meters wide, the new Atair will be the largest research vessel in the BSH fleet.
Maritime's 'Path to Zero': The Case for Ferries
Ferries have pioneered zero-emission technology deployment for good reason. Short routes and regular port visits provide opportunities for shipboard stored energy technology, and it is the commercial case that is turning the tide towards zero emissions where the ferry market is concerned. Supported by shoreside charging infrastructure, a fully charged battery pack can be used to propel a ship along a predictable route at relatively low operating cost and little wear and tear,…
