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…

Efficiency Gains from Eliminating the Hub Vortex

There is hydrodynamic solution that delivers multiple benefits for ship owners facing increasingly tough regulatory requirements and rising operational costs, writes Dr. Batuhan Aktas*One area of ship operations that has attracted much attention in recent years due to the possibilities it represents for emissions reduction is that of cavitation. During ship operations, cavitation occurs because of vortices that build up and cause bubbles to collapse under the ship’s propeller. The results of this process include increased noise, vibration and energy usage.

Is Stern Tube Damage Declining?

It might be easy to blame EALs, but the ongoing causes of stern tube damage are varied, and possibly declining.Environmentally Acceptable lubricants (EALs) gained market traction with the introduction of US VGP regulations in 2013. Since then, DNV has observed two major trends. The first, starting in 2013 was early life damage, either during sea trials or within the first five years of operation, where aft stern tube bearings typically failed under extreme load conditions. Then from around 2018…

Time is Running Out for some Fi-Fi Foams

A new IMO resolution will see the phase-out of foam firefighting systems that use fluorinated foams containing perfluoro-octane sulfonic acid (PFOS) as the foam-producing component. The new rules come into effect under a rolling programme beginning in 2026, but Swedish maritime engineering specialist Scanunit believes that a proactive replacement strategy should be put into effect now.Foam firefighting systems on ships typically make use of a family of synthetic chemical compounds known as perfluoroalkyl and polyfluoroalkyl substances (PFAS).

Enclosed Spaces: Engineering Solutions

If you think the human element is the only cause of enclosed space deaths, think again.Enclosed space incidents are cited as the largest cause of on-duty fatalities in commercial shipping. The risks can’t simply be engineered out, but there’s a powerful coalition wanting action nonetheless.There’s a tendency to blame failure to follow procedures, they say. Investigations seldom focus on the practicality of those procedures or the influence of the operating environment and vessel design, they say.

Failure to Maintain Crane Barge Led to $6 Million Loss

A barge owner’s lack of inspection and maintenance led to the capsizing and sinking of a crane barge last year in the Gulf of Mexico, the National Transportation Safety Board (NTSB) said.The crane barge Ambition was being towed when it capsized and sank on June 15, 2022, releasing an estimated 1,980 gallons of oil. No injuries were reported. The Ambition, owned by Rigid Constructors, and its crane were a total loss estimated at $6.3 million.Due to the height of the crane, the Ambition was being towed offshore in the Gulf of Mexico to reach its destination.

LPG: Dual-Fuel Engines Prove Their Worth

BW LPG has demonstrated the value of dual-fuel LPG operations beyond the company’s initial aim of meeting IMO 2020 Sulphur Cap regulations.In October 2020, the LPG carrier BW Gemini became the first very large gas carrier (VLGC) to have its low-speed main engine converted to an LPG dual-fuel engine. The project started several years earlier, sparked by Oslo-listed BW LPG’s preparations for the IMO’s 2020 Sulphur Cap regulations.Compared to heavy fuel oil, LPG reduces Sox emissions by approximately 97%…

Everett Ship Repair Completes Refrigeration Refit on the MV Excellence

Everett, Wash. repair yard Everett Ship Repair said it recently completed hull repairs and upgrades of the MV Excellence, a steel-hulled mothership processing vessel built in the 1970s in Japan. The vessel, measuring 367.5 feet in length and 56 feet in width, is undergoing extensive upgrades to the onboard ammonia-based refrigeration system. The modernization of this system will provide additional refrigeration capacity to the vessel, without an increase in power demand.The new refrigeration equipment was installed in a large opening cut below the waterline, necessitating drydocking.

America's Sea Services Building Large Fleet of Small Ships and Craft

Not every vessel in the U.S. Navy is built for major combat operations on the high seas. There are large numbers of boats and service craft that provide essential services to the sea services, the nation and its partners.The U.S. Navy procures about 100 small boats per year. Some of these boats are based on commercial designs, procured to a Navy developed specification that tailors the requirements to the end user needs. They are procured and managed by two Naval Sea Systems Command program offices—PMS 300 and PMS 325.Compared to warships and auxiliaries…
