For Matt Tremblay, Senior Vice President, Global Offshore at the American Bureau of Shipping (ABS), the opportunities are significant — but so are the challenges.Speaking with Offshore Engineer in Houston, Tremblay described an industry that is “very busy…

Taking your children or grandchildren for a ride on the Merry-Go Round may be a pleasant past memory. With that memory, we are asking to think about your choice of the best horse as you board the platform. A decision resting upon what you want out of the ride. Now consider that selection to the current state of US shipbuilding.Selecting the outside row of “jumpers” provides the greatest thrill as they move the fastest. When the Executive order for Maritime Dominance was issued on April 9, 2025, the U.S. maritime industry was ready to ride for the thrill of it.

On January 4, 2025, while moored in the Port of Mobile, Alabama, a foreign-flagged cargo vessel equipped with a SAACKE Monoblock Rotary Cup Burner SKVJ-M 14 Mark I burner system on a marine boiler experienced a significant engine room fire. The incident began with a high-pressure fuel leak from the oil fittings block, which caused atomized marine diesel oil to ignite on the hot surface of a nearby auxiliary generator exhaust stack. The fire rapidly spread from the boiler flat through two upper deck levels…

Since the closure of the Strait of Hormuz to most commercial shipping in late February 2026, an estimated 1,550 vessels, carrying approximately 20,000 seafarers, have been unable to transit, or have chosen to remain at anchor in the Arabian Gulf, Gulf of Oman, and approaches. Traffic through the Strait, which normally averages around 138 vessels per day, has fallen to near-zero on most days. The conflict began on February 28, 2026, resulting in vessels being idle for approximately 90 days.

Pakistan plans to boost domestic storage for crude oil and refined products to increase its energy security, according to a government document that was shared with oil producers and some of the world's leading trading firms.Despite depending on supplies through the Strait of Hormuz for up to 90% of its oil and liquefied natural gas imports, Pakistan has no strategic petroleum reserves.That has left it exposed to supply shocks provoked by the Iran war even as its lending programme…

A common concern of maritime chief engineers, regarding vessel engine damages, is the presence of highly abrasive “catfines” within marine fuel. To fully understand the seriousness of this issue, we first need to understand the source of the problem.Oil refineries use catalysts in their Fluid Catalytic Cracking Units (FCCU) or “Cat Plants” to process crude oils in the production of numerous products from the source crude. These catalysts are high in aluminum silicate (Al+Si) content and over time and repeated use, can breakdown and fragment into smaller particles, or catalytic fines.

There’s been no update on the project under the current administration…

US Coast Guard Sector San Juan Command Center watchstanders and the crew of the Horten Liberian-flagged tanker rescued a capsized rower in the Atlantic Ocean east of Puerto Rico, Wednesday night.Benoit Bourguet, 47, was in his single-man rowing vessel, City of Liverpool, which was reportedly struck by two rogue waves and capsized in 13 to 15-foot seas which forced Bourguet to deploy and board his life raft.Bourguet and the City of Liverpool vessel were competing in the World’s Toughest Row Race, a 3,000-mile rowing race from San Sebastian de la Gomera, Spain, to Nelson’s Dockyard in Antigua.

The recent rejection of around 2,900 dairy cattle on the Spiridon II raises animal welfare and pollution concerns when, after a long sea voyage, the laden vessel has again had to return to sea.The 52-year-old livestock carrier has left Turkey after its cargo was rejected by local authorities. Court transcripts translated by Animal Welfare Foundation indicate that 58 cows died in transit to Turkey, 140 cows had miscarriages in transit, 50 newborn calves were present on board, but another 90 are unaccounted for.Having departed from Montevideo…

By Captain Bobbie Scolley, U.S. Navy (ret.) and Rear Admiral Tim Gallaudet, U.S. Navy (ret.)For more than six decades, spanning from 1905 to the late 1970s, the U.S. Navy’s diving apparatus for deep ocean operations and salvage remained fundamentally unchanged. During this period, the demographic of navy divers also saw little alteration. However, beginning in the mid-1970s and continuing to the present day, a series of developments initiated a gradual transformation in both areas with significant implications for contemporary Navy diving.Donna Tobias…

A powerful magnitude 8.8 earthquake off Russia's Far Eastern Kamchatka Peninsula triggered tsunami waves of up to 5 metres (16 feet) and sparked evacuation orders in Hawaii and across the Pacific on Wednesday.The shallow earthquake damaged buildings and injured several people in the remote Russian region, while much of Japan's eastern seaboard - devastated by a 9.0 magnitude earthquake and tsunami in 2011 - was ordered to evacuate.In Hawaii, coastal residents were told to get to high ground or the fourth floor or above of buildings, and the U.S.

This week at MarineLink…An Australian Prime Minister once famously (infamously) said: “Life wasn’t meant to be easy.”He could have been talking about the maze of IMO and EU regulations relating to new fuels, especially the concept of well-to-wake emissions.It’s not enough to have a clean-burning engine or even an onboard carbon capture system. Well-to-take emissions, upstream and out of the control of ship operators, will have to be factored in.This week, MarineLink reported that a CMA-CGM vessel bunkered bio-LNG in Rotterdam…
