Ensuring smooth sailing on workboats and leisure vessels

Workboats and leisure vessels differ in purpose, but they have two things common. One is their size, which is similar for fishing vessels, tugboats, offshore supply vessels, wind farm support vessels, research vessels, general cargo vessels and even superyachts. The other is a need for everything to work as it should.

Alfa Laval delivers reliable, user-friendly equipment that’s built on a century of experience at sea. Whether you design, build or operate these vessels, count on us for performance, regulatory compliance and smooth operations – plus close support wherever your vessels sail.

Fishing vessel 2023

Achieving more with less effort

As on many workboats, time and money are in focus on the Dutch fishing vessel Prins Maurits. Using an Alfa Laval MIB 503 separator, Chief Engineer Auke van Slooten has doubled the life expectancy of his main engine’s lube oil, saving 1400 litres of oil a year and nearly two hours of cleaning time per week. Such results – and Alfa Laval’s close support – are the basis for a long history of cooperation.

Ballast water treatment

Alfa Laval PureBallast 3 excels in waters of any salinity, including challenging low-clarity waters. Type approved by IMO and the U.S. Coast Guard, it provides a compact and plug-and-play solution, no matter if you choose a skid-mounted system or loose components for total flexibility.

Oily water separation

Alfa Laval PureBilge Compact is a fully automated centrifugal separation system that cleans oily water effectively at sea. With options to reduce oil pollution below 5 ppm –far tougher than the 15 ppm IMO requirement – it sets a new standard in making water safe for discharge overboard.

Lube oil filtration

The Alfa Laval Eliminator combines two technologies in one housing to extend lube oil life. The full-flow automatic filter protects the engine, while a disc-stack separator on the backflush line efficiently cleans the oil.

Marine refrigeration

Refrigerants are common in the marine industry, from chilling and freezing the catch on fishing vessels to air conditioning on cruise ships. Yet the refrigerant types are changing rapidly. Chlorofluorocarbon (CFC) and hydrochlorofluorocarbon(HCFC) refrigerants have given way to hydrofluorocarbon (HFC) refrigerants, and now many shipowners are exploring natural refrigerants like CO2. Alfa Laval has the heat exchanger solutions and expertise to support natural refrigerant choices.
