For a marine or industrial application requiring a thermal management solution, one of the most important decisions an engineer must make is between gasketed and brazed plate heat exchangers. Both technologies function using the same heat transfer pr...

Marine biofouling, which involves attachment of microbes, seaweeds, crustaceans, mollusks such as barnacles to submerged surfaces, is not only operationally problematic for vessels and structures but also environmentally hazardous. Classic anti biofo...

SME Group has been working closely with shipowners and operators in this complex area of underwater hull maintenance for more than 20 years. One of the most debated topics in our industry—discussed daily in our Nantong workshop and on calls wor...

High salinity seawater is one of the toughest environments for a marine heat exchanger to operate in. In locations like the Arabian Gulf, Red Sea and sections of the Mediterranean, the water can have salinity greater than 40ppt, as well as high water...

Of all the views in an engine room, a weeping, dripping, or spraying PHE is perhaps the most unnerving. Not only do you lose fluid, but a leak represents an unacceptable breach between two fundamental systems - usually between the engine coolant and ...

On offshore support vessels (OSVs) such as anchor handling, platform supply vessels and crew transfer vessels marine environments can often be amongst the most extreme on the planet. Long periods at sea and a need for a high proportion of dynamic pos...

Engine Room Performance has moved beyond the days of just measuring fuel consumed per nautical mile. Engine Room efficiency today involves so much more than just this: thermal optimization, less energy is used by pumps, maintenance downtime has been ...

Life on Board Marine vessels can be one of the toughest environments imaginable. The high salinity, presence of oxygen and numerous marine activities in the seawater constantly challenge heat exchanger equipment. Corrosion, pitting, crevice corrosion...

For the purpose of marine engineering, no operational environment is as complex as that presented on cruise ships. In order to enable these floating metropolises, the most extreme cooling requirements must be satisfied for propulsion, air conditionin...

The heart of any marine vessel is its engine room and the cooling system of that engine is the life force maintaining its optimum operating temperature. For decades, shell-and-tube heat exchangers reigned supreme as the ubiquitous marine engine cooli...

We’ve long been told that shell and tube heat exchangers are king in ship engine rooms, they’re reliable, well-understood and have been around for donkey’s years. However, the development of space-efficient, high performance Plate H...

The Unheralded hero of any modern ship – the Plate Heat Exchanger (PHE), rarely makes it to the main event unless something has gone terribly wrong. Tasked with cooling everything from main engines, generators, and lubricating oil and freshwate...
