Where heavy oil cabinet of daily use has its bottom level vertically higher by 2 or over 2m than the bottom level of oil supplying unit installation, one may select the two-pump type oil supplying unit, as this unit has low pressure for the air depletion in oil mixing, which reduces the evaporating temp of the light substances and water content in the fuel oil in high tempt oil return pipe. Two-pump type suits fuel oil below 1500s by Redwood viscosity scale.
The tonnage of the vessel, or container number, type of vessel, kind of fuel oil the vessel is going to use, location of shipyard where the vessel is built, and its main routes of voyage
Number of main engines or aux engines that consume heavy oil, manufacturer of the engine, their power and routine operating load, low speed engine or medium speed engine
Setup of the heating equipment on board, whether or not equipped with steam/heat conducting oil fuel boiler, waste steam boiler, hot water boiler, waste gas heat conducting oil boiler or waste gas from fuel oil combination boiler etc. Parameters such as steam evaporation volume and evaporating pressure
Power supply mode: normally 380V/50Hz/3Φ; in special cases where 440V/60Hz/3Φ、220V/60Hz/3Φ or others are used the relevant situation will have to be given.
In principle it is not recommended to use the main heating setup as electrical heating of the oil supplying unit. It is selected only when there is no other heating source in the cabin. However, electric heating can be an aux standby source of heat.
Layout of machine cabin and oil cabinets (oil tank, sedimentation cabinet, daily use cabinet and dirty oil cabinet)
You will please provide above mentioned plant conditions for us to give reference in type selection of purpose of optimum working conditions.
Two choices are available of oil supplying unit structural layout: 3-D individual cabinet control mode and plane integrated control mode. Unless customer specifies otherwise, control setup will be flat integrated mode. |
