DESIGN CALCULATIONS FOR THE COOLING WATER SYSTEM OF A TUG BOAT
Journal Title: World Journal of Engineering Research and Technology - Year 2017, Vol 3, Issue 4
Abstract
The cooling water system is primarily used to ensure that the temperature of the main engine is kept within the acceptable limit for maximum performance during operations. The system also is used to remove or conduct heat out of hot surfaces or materials either directly or indirectly. This system comprises of different components, sub- systems, piping and fittings, valves, sea water and fresh water pumps, filters, tanks and condition monitoring device amongst other. The sea water cooling system was calculated mathematically to obtain the volumetric flow rates of the sea water for the cooling of the shaft-line bearing, reduction gear lube-oil, and the hot well. Similarly the fresh water flow rate and the transfer surface areas within the main engine were also obtained for the jacket water cooler, piston water cooler, crankcase lube-oil cooler and charger air cooler. All designs were carried out obeying classification rules relating to this capacity of the Sea-going Tug Boat bearing in mind the capacity of the load to be transported.
