Provide for data logging, remote control and automatic action-pneumatic electro￾pneumatic, and electronic equipment, self￾regulating apparatus, etc. The chapter will give a general instruction above system and function. The other chapters of the book focus on the oil handling devices onboard

In motorships there are two main circuits, one salt , one fresh. The salt circuit is: sea inlet box (seachest) - pump(s) - f.w. coolers in series (first LT then HT) – turbo blower aftercoolers in parallel (if any) – provision condenser in parallel (if any) - overboard

Air at high pressure, i.e. at 25 bar or more, is required for starting main and auxiliary engines in motorships. Air at low pressure, say at 6 bar or less is required for much remote or temperature or pressure controlled equipment, for which purpose it must be clean and oil-free

A fire and bilge pump has suctions from sea, bilge main and engine room bilge, with discharges to fire main, oily water separator and overboard. A ballast pump has suctions from sea, ballast main, engine room , bilge direct and bilge main with discharges to overboard, the ballast main, the oily water separator and possibly, the main salt water circulating system

Learning Objectives The learning objectives of this section are to make all engineers, engine cadets and other crew members who are involved in the handling of fuels onboard, familiar with: – How to handle the fuel. – Take the necessary simple precautions by following test procedures

Learning Objectives The main objectives of this section are to make all engineers familiar with: Pre-treatment of marine fuels. Design criteria, or problems related to settling and service tanks. Draining of settling tanks. Preheating. Separation, purifier and clarifier. Sludge and sludge handling

3.2 Treatment of detergent type lubricating oils The main function of detergent lubricating oil is to keep solid contaminations in suspension and prevent both their agglomeration and deposition in the engine. This function reduces ring sticking, wears of piston rings and cylinder liners, and generally improves the cleanliness of the engine. agglomeration

3.3 Batch and continuous lubricating systems For small or medium units without a circulatory lubricating system, the oil is often treated on the batch system. As large a quantity of oil as possible is drained from the engine at intervals and run into a heating tank, the system being replenished with clean oil at the same time

3.4 ALFA-LAVAL Separator MAPX 207S-20 general information 3.4.1 MAPX information Contents – Correct installation, suitable treatment of the liquid before and after the passage through the machine, – correct operation and handling of the machine according to the directions given in instruction book, – cleanliness, carefulness and methodical overhaul are factors of the greatest importance for ensuring the best machine function and intended results

Cleaning, overhaul, lubrication. Satisfactory functioning cannot be ensured unless the parts in contact with liquid are carefully cleaned before assembly. This applies particularly to seal rings, sliding surfaces, guiding and contact surfaces, and threads. Also take care that no burrs are knocked up on the metal parts when handling them. Follow the directions given in chapter 5.4 and 4.5
