Hughes Pumps has designed and manufactured a custom pumping system for MOL Tankship Management (Europe) Ltd., for repair and maintenance of the company’s methanol tankers while at sea.
To reduce corrosion and extend the working life of its fleet, MOL identified a need for Ultra High Pressure (UHP) water-jetting equipment to remove loose scale and coatings from ballast tanks and deck areas before recoating.
Hughes developed a system that overcame several challenges, designing a hydraulic-motor-driven pump-set that could use the ships’ own hydraulic supply to power the UHP pump and that would fit within the 1.2 meter-wide flying bridge that runs the length of the deck.
|The system was designed for maintenance while at sea. |
The result: a hydraulically driven, compact Ultrabar 24 pump-set with a performance of 23lpm at 2750 bar (40,000 psi). The system uses a four-person riding crew to carry out water jetting on the company’s methanol tanker fleet during voyages between the Caribbean, Europe and Gulf of Mexico. Fresh water is used in the jetting process, followed by wash-down, de-humidifying and repainting.
Founded in 1868, UK-based Hughes Pumps manufactures UHP water jetting (also known as water cutting or hydro blasting) surface preparation equipment for the shipping, marine, oil and gas industries. The equipment is available in electric motor or diesel engine driven, suitable for use in safe or hazardous areas, and can be built into certified lifting crash-frames or containers if required, according to the manufacturer.
