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…

The volunteer fire department in Greene, Maine recently took delivery of a 16-foot RIBCRAFT 4.8 rescue boat. This specialized RIB expands the department’s response capabilities while providing a safe platform for rescue missions. Funded by a grant through Firehouse Subs, RIBCRAFT worked with the department to build a boat that met all of their operational requirements.Located on several rivers and lakes in Androscoggin County, the department receives many distress calls from recreational boaters.

Humans have sailed the world’s oceans for thousands of years, but they haven’t all reached port. Researchers estimate that there are some three million shipwrecks worldwide, resting in shallow rivers and bays, coastal waters and the deep ocean. Many sank during catastrophes – some during storms or after running aground, others in battle or collisions with other vessels.Shipwrecks like the RMS Titanic, RMS Lusitania and USS Monitor conjure tales of human courage and sacrifice, sunken treasure and unsolved mysteries.

South Korean authorities cited the risk of Chinese economic retaliation when they charged marine technology firm SI Innotec last year with violating trade laws for its work on Taiwan's new military submarine program, according to a police document seen by Reuters and two people familiar with the matter.In a Feb. 17, 2022, affidavit to a judge seeking the arrest of SI Innotec executive director Park Mal-sik, police said authorities feared a repeat of the sweeping sanctions imposed by Beijing in 2016, after Seoul decided to install THAAD, a U.S. anti-missile system.

The number of stern tube-related damage claims has increased considerably over the last few years, and this is causing marine insurer Gard some concern.In the past, damage to a stern tube was often considered a relatively straightforward casualty by surveyors. The cause was often obvious – contact with a floating object such as ice, fishing nets or ropes, for example.These causes still exist, but the significant increase in frequency over the past years, without any apparent explanation…

I was discussing torsional stiffness in ship’s hulls with one of our intern engineers and pointed out a torsional stiffness problem with a certain hull design section since it could not inscribe a decent sized circle.I expected it to be a comment that would be confusing to a young engineer and proceeded to explain that torsional stiffness is related to gyradius which is powerfully related to radius and radius is related to circles. Inherently the stiffest shape in torsion is a…

In November 2020 I wrote a column in MREN that discussed the right of people to engage in crazy marine ventures. The example I used in that column was an attempt to row from South America to Antarctica. In it I also made note of the inherent unseaworthiness of single-handed ocean racing and noted that such foolishness often resulted in the public spending lots of money providing rescue services.The Ocean Gate Expedition Titan venture has now managed to set an entirely new standard…
