Combustion defects

Normally the combustion in each power cylinder should be smokeless and complete and occur early in the stroke. Insufficient breaking up of the oil during injection will cause slow and incomplete burning and may be the result of clogged fuel nozzles, oil too cold or incorrect timing. Other causes of incomplete burning are compression too low, injection valves not correctly timed and air inlet pipes clogged.

Lubricating system defects

All Diesel engines today are lubricated by the forced feed method and no hand oiling of any part is required. This requires that the engine housings be closed in, to prevent loss of oil through splashing, and the oil piping, with the oil circulating pump, forms a closed circuit through which the same oil circulates repeatedly. Of course the most serious derangement in such a system is loss of pressure.

Air system defects

The most serious derangement that can occur in the air system of an air injection engine, aside from the remote possibility of an explosion, is loss of injection air. Assuming that the compressor suction is open and the bleeder valve in the first stage properly adjusted, a falling off in the air pressure may be due to leaky, broken or stuck compressor valves, an injection valve sticking open, leaky air valve stem packing, leaky joints in the air piping or failure of the cooling water supply. If the air pressure falls to somewhere near the compression pressure in the power cylinders, unless the trouble can be located immediately, the engine should be stopped. If the engine is kept running, there will be a possibility of an explosion inside the injection valve body.

Operating troubles in general. Water in fuel oil. Water may get into the fuel oil by leakage through defective riveting of tanks, through alternate use of tanks for fuel oil and water ballast, or the fuel oil as delivered into the tanks may contain considerable moisture that will settle out. The degree of seriousness of the resulting troubles will vary with the amount of water in the oil, but among the possibilities are cracked heads and pistons, burned out exhaust valves, low compression due to wear of rings and liners, and irregular running of the engines.

Improperly refined oil. Fuel oil must, during the refining process, be treated with sulphuric acid and this acid must later be neutralized with soda. If this neutralizing agent is not thoroughly washed out of the oil, its presence cannot be detected without chemical analysis nor is it removed by the filtering and straining methods ordinarily used on shipboard. When the engine is opened up after running on this insufficiently washed oil the entire surface of the combustion spaces in the cylinders will be found to have a coating of gritty material which looks and feels like sand but which is mostly sodium sulphate. It does not cause any immediate derangement of the engine but it does cause considerable wear of piston rings and cylinder liners. When such deposits are found the only remedy is to stop using the fuel from that particular refinery.

 Loss of power or slowing down of engine. When this occurs the first possibility that should be investigated is hot bearings. Other causes are failure of fuel to one or more cylinders, derangement of valves of valve gear or a fall in cooling water temperature. A decided reduction of the sea water temperature will often be experienced when entering a river from the sea, passing out of the Gulf Stream or leaving tropical waters. When this occurs the cooling water supply should be cut down until the jacket water temperature is up to normal. A distinct loss in efficiency sometimes results from the idea that the jacket water should always be kept as cold as possible.

Cracked cylinders and cylinder heads. Cracks may result from unequal heating due to poor design, bad castings, air pockets in jackets, lack of cooling water and overloading. Modern practice in design and construction has greatly reduced the probability of cracking from the first two causes and watchfulness on the part of the engineers eliminates the other causes, so that cracked heads and cylinders are not nearly so common as they were in the early days of Diesel engineering.

Cracked crank shafts. During the early development period cracked crank shafts were so common that it was considered one of the inevitable hazards associated with Diesel engine operation. This trouble has become very rare, however, in modern practice.

Vibration. The amount of vibration of an engine and of the ship's hull in which it is installed will depend on how well the reciprocating and rotating masses in the engine are balanced and the position of the engine relative to a nodal point in the hull. These are both matters over which the operating engineer has no control. Normally Diesel engines, especially in the large sizes, run with very little vibration but it sometimes happens that an engine will have a critical speed, a speed at which the twisting impulses imparted to the crank shaft by the pressure acting on the pistons coincide with the natural period of vibration of the crank shaft. When the engine operates at this speed violent vibration will occur that may result in loosening nuts, shaking off small fittings, breaking pipes and even breaking of the crank shaft, if continued long enough.

They must inspect all fuel and lubricating oil pipework for leakage. Any defects must be immediately reported to the Engineer of the watch being relieved. The Engineer being relieved is toinform the relieving Engineer of the status of all plant, service tanks and suctions in use and any defects which call for special attention. On taking over the watch the Engineer of the watch is tofamiliarize himself with the standing orders and instructions in the Chief Engineer Order Book and to acknowledge these instructions by his signature.

While keeping a watch at sea or in port the Engineer of the Watch is responsible for the safe and efficient operation of all equipment and machinery, the safety of all personnel in the machinery spaces and for the prompt and efficient response to order from the Bridge or Cargo Control Station. If main engines are operating under Engine Room Control the responsible Engineer shall remain in the vicinity of the engine controls in order to respond rapidly to telegraphed orders. When personnel are engaged in maintenance or other duties within the machinery spaces, the Engineer of the watch shall ensure that they conduct their duties in a safe and efficient manner. At first indication of trouble the engineer on watch shall notify the chief engineer and take immediate steps to prevent damage to machinery. He must report to the chief engineer any change of the ME speed or other orders from the bridge. In case of emergency or malfunction corrective actions should be taken immediately, for example, steam, air, oil or water leaks must be repaired promptly. When any alarm or protective device is found defective the repair or replacement should be carried out at once.

When the ship is manoeuvring, the engineer on watch devotes his primary attention to complying with the orders from the bridge. All bridge orders shall be promptly executed. Changes in direction or speed of the main propulsion unit shall be recorded. 

Before getting underway the engineer on watch jointly with the OOW shall test the ME with necessary auxiliaries, the steering gear, whistle and running lights (ходовые огни). An appropriate entry shall be made in the log. The engineer on watch shall record required data in the log book including any unusual occurrences and he shall sign the log upon the completion of his watch.To avoid any danger to the safety of the ship and its crew, the bridge should be immediately notified in the event of fire, impending actions in machinery spaces that may cause reduction in ship’s speed, steering failure, stoppage of the ship’s propulsion system or any alternation in the generation of electric power or similar threat to safety.

When the engine room is put in a stand-by condition, the engineer on watch shall ensure that all machinery and equipment which may be used during manoeuvring is in a state of immediate readiness and that an adequate reserve of power is available for steering gear and other requirements.
