  • Testing of Marine Boiler Feed Systems
    Ships boilers are the heart of a steamship, when they are not operating efficiently the ship begins to lose speed. To keep the boilers running at optimum efficiency the testing of marine boiler feed systems before they can cause problems to boiler water pipes and internal fittings is imperative
  • Ship's Boiler Steam Supply for Accommodation and Deck Equipment
    Ships boiler steam supply for accommodation and deck equipment must be reduced in pressure before use. It is then used in the accommodation for heating and, by the galley for steam cleaning worktops / cooking utensils. Steam is also supplied to the deck to drive winches and anchor windlasses.
  • Marine Boiler Auxiliaries, Fixtures and Fittings
    Marine boilers auxiliaries include the boiler control system, forced draught fans, de-superheater, fuel oil pumps, heaters and filters, exhaust gas air and feedwater heaters. Fixtures and fittings consist of steam safety valves, feed control valves level glasses, sootblowers and blowdown valves.
  • Treatment of Marine Main Diesel Engine Fuel and Lube Oils
    Ships marine diesel engines run on heavy fuel oil (HFO) nowadays a low sulfur content, or marine diesel oil (MDO)The lube-oil coats the revolving and reciprocating components dissipating the heat caused by friction. It is imperative that these systems have adequate centrifuge and filtration systems.
  • Resurfacing of Bronze Rudders and Propellers
    Resurfacing of bronze rudders and propellers is required after the boat has been subjected to the ravages of seawater immersion. This causes several types of corrosion that along with flow induced damage leave the components badly pitted, necessitating a spell on the slips to remove them for repair.
