CHARTERER - It is a person or company who hires a vessel for a specified voyage or a specified period of time.  There are three types of chartering: Voyage charter Time charter Bareboat charter VOYAGE CHARTER: A voyage charter is the hiring of a vessel and crew for a voyage between a load port and a discharge port. The charterer pays the vessel owner on a per-ton or lump-sum basis. The owner pays the port costs (excluding stevedoring), fuel costs and crew costs. The payment for the use of the vessel is known as freight. A voyage charter specifies a period, known as laytime, for loading and unloading the cargo. If laytime is exceeded, the charterer must pay demurrage. If laytime is saved, the charter party may require the shipowner to pay despatch to the charterer. In a voyage charter, laycan days are given to the owner. Laycan is a period of lay days plus canceling date. During this period vessel must arrive and be presented at the load port/place. If the vessel arri

Fire in Machinery Space - Actions to be taken

Fire fighting starts from the moment a person detects fire and raises the alarm. First action can be taken right after raising alarm, such as use of portable extinguisher, etc., but such action should not aggravate the situation. Ventilators, doors or portholes to the compartment on fire should be shut and not to be opened till a fire-fighting team is available. In case a crew member is believed to be trapped, action to allow him to escape should be taken urgently. Inform terminal on pre-agreed emergency channel and cease all cargo operations if the vessel is in port. When the vessel is at sea we should stop main engine, if necessary and make appropriate signals to ships or port nearby if required. If required the Emergency Squad shall take over and attack the main seat of fire, making use of fireman's suit with self-contained breathing apparatus and applicable fire fighting medium present. The Support Squad should prepare life-saving appliances. Distress signals must be

Blow- Down Procedure for a Marine Boiler & Why its Done?

Boiler blowdown is of two types: Scum Blowdown Bottom Blowdown Procedure for scum and bottom blowdown: Below is the procedure for boiler blowdown using the blowdown valve located at the bottom of the boiler. In order to do scum blowdown, instead of bottom blowdown, the scum valve is to be opened. Open the overboard or shipside valve 1 first. Open the blowdown valve 2, this valve is a non-return valve. The blowdown valve adjacent to the boiler 2 should be opened fully so as to preventing cutting of the valve seat. The rate of blowdown is controlled by valve 3. After blowdown close the valve in reverse order. NOTE : A hot drain pipe even when all valves are closed indicates a leaking blowdown valve. Boiler blowdown is done to remove sludge deposits and other impurities from the boiler water. Blowdown of the boiler is done to remove two types of impurities-scum and bottom deposits. This means that blowdown is done either for scum or for bottom blow down. Moreover, the re

What would you do in the event of Oil Spill?

Raise the alarm, inform bridge and chief engineer. There should be a set drill for oil spills, which is practiced regularly. If possible contain the spill on deck and start clean-up procedures using appropriate oil spill equipment. If the oil has spilled into the sea: if in port, port authorities should be informed. If ar sea: coast guard should be informed. The time od spill should be recorded with the place or position of the ship at the time of spill along with approximate quantity and type of oil. Circumstances of discharge or escape would be logged in the oil record book.

Procedure for Blow Down a Boiler Gauge Glass?

Close the water and steam cocks on the gauge glass and open the drain. Then open the steam cock-a strong jet if steam should be seen from the drain. Close the steam cock. Open the water cock-a strong jet of water should be observed from the drain. Close the water cock and then close the drain. Then open the water cock, the water will rise in the gauge above the normal level. Then open the stem cock, the water should then settle down, finding its correct level.

What Steering Gear Checks to be done Before Departure from the Port?

Prior to a ship's departure from any port, the steering gear should be tested to ensure the satisfactory operation.  This tests should include, Operation of the main steering gear Operation of auxiliary steering gear or the use of the second pump which acts as an auxiliary Operation of the remote control system from the main bridge steering positions Operation of steering gear using the emergency power supply The radar angle indicator reading with respect to actual radar angle should be checked The alarms fitted to the remote control system and steering gear power units should be checked for correct operation. Steering gear header tank levels should be checked. During these tests the radar should be moved through its full travel in both port and starboard and the various equipment items, linkages etc visually inspected for damage or wear. The communication system between the bridge and steering gear room should also be checked.

Why are High and Low suction fitted on F.O Service Tank?

The high and low suctions are a safety feature to prevent shutdown of main engine, generators and boilers due to water contamination of the fuel.  Normally the low suction is kept in used if any water should find its way into the fuel and service tank, it will gradually separate towards the tank bottom when it becomes apparent water is present by finding it at the tank drains or by operation of the engine, it is possible to bring the high suction into operation and avoid shutdown.

De-Rating of Main Engine

An option available to reduce the specific fuel consumption of diesel engines is derated or so-called "economy" ratings . This means an operation of an engine at its normal maximum cylinder pressure for the design continuous service rating, but at lower mean effective pressure and shaft speed. By alternating the fuel injection timing to adjust mean pressure/ maximum pressure relationship the result is a worthwhile saving in fuel consumption. The horsepower required for a particular speed by a given ship is calculated by the naval architect and once the chosen engine is coupled to a fixed pitch propeller, the relationship between engine horsepower propeller revolutions and ship speed is set according to the fixed propeller curve.   A move from one point on the curve to another is simply a matter of giving more or less fuel to the engine.  Derating is the setting of engine performance to maximum cylinder pressure at lower than normal shaft speeds, at a point lower
