Control Tests on Ships

The main engine and the steering engine are located aft and far from the bridge and controlled by a maze of wires, pipes, machines, and electronic devices. Prior to entering a port and departing the port, these control systems have to be tested to ensure they are working properly and are effective.

Control Tests. The ship is controlled from the bridge, which is at the top deck of the accommodation. The wheel house, so called as it houses the wheel to control the steering engine, has a number of control stands including the main engine control stand and the telegraph. The main engine is housed in the engine room which is at the aft of the ship below the water line. The main engine is controlled by electro-hydraulic and pneumatic controllers that give signals to the main engine. It is essential that this complex piece of machinery is tested prior to any crucial operations like maneuvering, and these tests are called control tests.

The control test is performed before sailing out and before arrival at a port. It is mainly done to confirm the safe operation of the ship and to ensure that all the control systems necessary for sailing are correctly functioning in a satisfactory manner.

The control tests are:

1. Telegraph checks

2. Steering gear checks

3. Main Engine try out in ahead and astern directions on fuel

4. Communications tests

After carrying out the control tests it should be logged in the bell book stating that the control test was carried out in a satisfactory manner and was successful (for legal purposes).

A diesel engine is similar to the gasoline engine used in most cars. Both engines are internal combustion engines, meaning they burn the fuel-air mixture within the cylinders. Both are reciprocating engines, being driven by pistons moving laterally in two directions. The majority of their parts are similar. Although a diesel engine and gasoline engine operate with similar components, a diesel engine, when compared to a gasoline engine of equal horsepower, is heavier due to stronger, heavier materials used to withstand the greater dynamic forces from the higher combustion pressures present in the diesel engine.

The greater combustion pressure is the result of the higher compression ratio used by diesel engines. The compression ratio is a measure of how much the engine compresses the gasses in the engine's cylinder. In a gasoline engine the compression ratio (which controls the compression temperature) is limited by the air-fuel mixture entering the cylinders.

Another difference between a gasoline engine and a diesel engine is the manner in which engine speed is controlled. In any engine, speed (or power) is a direct function of the amount of fuel burned in the cylinders. Gasoline engines are self-speed-limiting, due to the method the engine uses to control the amount of air entering the engine. Engine speed is indirectly controlled by the butterfly valve in the carburetor. The butterfly valve in a carburetor limits the amount of air entering the engine. In a carburetor, the rate of air flow dictates the amount of gasoline that will be mixed with the air. Limiting the amount of air entering the engine limits the amount of fuel entering the engine, and, therefore, limits the speed of the engine. By limiting the amount of air entering the engine, adding more fuel does not increase engine speed beyond the point where the fuel burns 100% of the available air (oxygen).

 

1) A diesel engine is similar to _______________________.

2) _____________________ is the result of the higher compression ratio used by diesel engines.

3) In a gasoline engine the compression ratio is limited by ___________________.

4) ____________________________ are self-speed-limiting.

5) Engine speed is indirectly controlled by _____________________.

6) Limiting the amount of air entering the engine limits _____________________.

4) He asked me: “Do know the construction of the incinerator?”

5) The Chief Engineer: “Have you finished fuel oil separation?”

6) My assistant: “Yesterday at 5 p.m. we were repairing the fuel lift pump”.

7) The Second Engineer: “You should replace plungers and sleeves”.

Engine-room Watchkeeping

1. Purpose

The purpose of this procedure is to establish the engine room watch keeping guidelines.

These guidelines are established within the Standard for Training, Certification and

Watchkeeping (STCW).

2. Responsibility

It is the responsibility of the Chief Engineer to assign the engine room watch keeping assignments and establish the watch keeping standards.

3. General

At Sea Watches

The normal at sea engine room watches are performed on a 4 and 8 watch rotation.

Each watch is 4 hours long. Starting at midnight the 2nd Assistant Engineer and an Oiler have the watch. At 0400 the 1st Assistant Engineer and the senior Oiler stand the next 4 hours until 0800. The 3rd Assistant Engineer and the third Oiler have the watch from 0800 to 1200. At noon the rotation resumes again.

In Port Watches

Normal in port watches start and end at the discretion of the 1st Assistant Engineer and the Chief Engineer. The rotation is also at the discretion, though usually will start with the watch that was due to have the next watch at the last in port period. In port watches are 24 hours long with the licensed engineer and an Oiler alternating 6 hours on and 6 hours off. The watch stander with the 6 hours off must be aboard and be on call during the entire watch period. The Oiler starts at noon and at midnight. The licensed Engineer starts at 1800 and 0600. The noon watch change must be handed over to the licensed Engineer coming on duty by the Engineer being relieved.

On Watch

The watch stander’s primary responsibility is to be present monitoring the engine room from the ECR. The engineer and the Oiler should alternate making rounds in the Auxiliary Machinery Space, Main Machinery Space and SCR room. The thruster rooms, motor room and fan rooms should be checked at least once each watch. Depending on operations, deck machinery should also be checked.

Watch standing is a science as well as an art. Watch standers must keep aware of

normal machinery sound, temperatures and vibrations so they can be alert to small

changes form the normal running of the machinery and so head off larger problems.

1) The responsibility of the Chief Engineer is to assign the engine room watch keeping assignments and establish the watch keeping standards.

2) Thenormal at sea engine room watches are performed on a 3 and 6 watch rotation.

3) The 3rd Assistant Engineer and the third Oiler have the watch from 1200 to 0400.

4) Normal in port watches start and end at the discretion of the 1st Assistant Engineer and the Chief Engineer.

5) In port watches are 12 hours long with the licensed engineer and an Oiler alternating 6 hours on and 6 hours off.

6) The watch stander’s primary responsibility is to be present monitoring the engine room from the ECR.

7) The thruster rooms, motor room and fan rooms should not be checked at each watch.
