All pumps, lines, instrumentation and other cargo equipment should be checked and tested as required. This will mainly be completed prior to arrival in port. b. Complete the ship/shore safety checklist. This contains many safety items. E.g.: ensure all scuppers are plugged, Ensure all unused manifold connections are blanked, Means of communication between ship and terminal are agreed. Smoking regulations are to be followed. f ollowed. Air-conditioning Air-conditioning units are set to recirculation recirculation etc. c. A comprehensive cargo plan indicating a chronological sequence of event is drawn up. This must include all operation involving the cargo, ballast and COW operations. d. The tanks must be checked inerted prior to starting operations. When discharging the IG plant must be running and ready to supply good quality IG immediately immediately pumps are started. e. Gas Risers and / High velocity vents v ents must be set as required. f. All lines should be set and checked by responsible officer. Procedures during loading Cargo is initially started slowly to minimise the generation of static electricity and to enable initials checks to be made before committing to the full a greed bulk rate. Initial checks are made a. E.g.: cargo flowing into into the the right right tanks, tanks, b. No leaks at the manifold, pump-room, on deck, overside, into segregated ballast tanks, c. Pump pressures, temperatures are satisfactory, d. IG delivery or venting is satisfactory. Increase rate slowly to the agreed maximum Try to ensure that more than one tank is open at a one time and manipulate valves carefully to avoid pressure surges within the ship and shore lines. Monitor tank ullage at regular intervals using the fixed tank gauging system. Monitor line pressures, pump pressures, pump bearing temperatures, IG pressures and oxygen contents, COW machines, etc continuously. Complete COW programme as per the agreed plan. Calculate final tank ullage to ensure final trim, list and draft as required. Ensure there is enough ullage space for the shore line contents if required and for expansion during the voyage. Reduce loading rates for topping off and ensure that there are sufficient experienced personal to complete this. Complete loading/discharging, draining lines as required. The latter is particularly important on discharge to ensure the minimum ROB. On completion of bunker operation 1. Check all ullages and temperatures with shore representative, taking appropriate precautions against static discharge and calculate the ships figure of cargo. The ships figure should generally be within 0.25% of the Bill of loading figure 2. The ship must be battened down for sea i.e. ullage ports, venting system, IG system, pipeline systems, pump-rooms etc. 3. PV valves should be set.

July-09 (4 marks) A reduction in the ship’s stability caused by the free flow of liquid in partially filled tank. There is no FSE if the tank is full or empty. The effect of free surface is that the movement of liquid in the tank as the vessel heels causes vessel’s CoG to move off the centre in the direction of the low side. Thus GZ is redu ced and therefore therefore GM will w ill also be reduced. Since M is considered a fixed point and the GM is reduced-then G1 must be considered to have risen.

When passing from Dockwater to Saltwater the draft will decrease.

[email protected] (LOWESTOFT) d. If a ship is loaded to her loadline at a Dockwater berth then draft would decrease on reaching the saltwater. She is not loaded to her maximum capacity and so loosing cargo revenue. e.

Lower all portable weights including derricks and cranes. If vessel is loading, discharging using ships gear – gear – lower all suspended weights to deck. b. Reduce free surface: fill partially filled tanks – if necessary transferring transferring FROM partially filled tanks on the high side. Pump bilges b ilges high side first. c. On LOW side: ballast into smaller tanks near centerline if possible (to reduce FSE and minimise the angle of inclination). d. In the event of ice accretion: remove ice from the HIGH side first. e.

88.Explain 88. Explain The Difference Between An Angle Of List And An Angle Of Loll. March-05 (5 m) A angle of list is caused by uneven distribution of weight.. 2. In port this may be co corrected rrected by distribution of cargo or ballast operation. 3. At sea this is done by the transferring of bunkers or ballast or ballasting to the high side, or ballasting ballasting the low side. 4. An angle of loll is caused by the ship having a negative GM (i.e when G is above M); the ship then heels until the GM becomes zero (because of the increased water plane area as the ship heels) and will roll about that point. 1.

101. Sketch a transverse labeled diagram illustrating a heeled vessel neutral ne utral equilibrium*** h) Neutral Equilibrium. a. GM is 0 (G&M in same position) b. GZ is 0-there is no R ighting Lever c. A ship is said to be in a neutral equilibrium, if when inclined she remains at the same angle until further internal or external forces are applied. For this to occur: d. G and M in the SAME Position e. This is a dangerous condition
i) Unstable Equilibrium. a) GM is Negative (G below M) b) GZ is negative Righting Lever c) A ship is said to be in a unstable equilibrium, if when inclined at a small angle she tends to heel over still further. For this to occur: d) G must be above M (Negative GM) e) This is a dangerous condition
