Australian Pump Industries (Aussie Pumps) has launched a 4-inch NiAl bronze self-priming pump with hydraulic drive.The new pump, called the B4XRA/B HYD34, produces 2,200 lpm and can operate at up to 42psi. It can also lift water through a vertical suction lift of 6m.Aussie Pumps Chief Engineer John Hales said: “The pumps self-prime. You can see from the big tank that’s designed into the body. When the product is properly primed it will have no trouble fulfilling its suction responsibilities in any installation.”“Most vessels today have hydraulic capabilities.

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 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…

The maritime industry has seen a very long sequence of environmental regulations since the first implementation of MARPOL in the early 1970’s. All of these regulations have very much benefitted the ocean environment and also our industry to some degree. One of those regulations, OPA90, has had an outsized effect to an extent that it may no longer be as effective as it was in recent years due to its own success.Tanker oil spills in the United States have become so rare that people with actual U.S.

When on route to the Gulf of Mexico area, a fully laden bulker hit a buoy off the coast of Colombia damaging the propeller blades and aft seal assembly.

When a 9,280hp workboat returned to service following extensive repairs at the James Marine Paducah River Service yard in Kentucky, U.S.A., it marked the first application of Thordon’s new seal-embedded bearing to an articulating rudder, Thordon Bearings said Monday. Articulating rudders are unlike conventional rudders and can be more costly to repair when things go wrong. They are more susceptible to wear and tear, due to the higher operating pressures and abrasives, and as a result…
