Load 450 t at Kg 6.50 m, 2.00 m to port of the centreline Load 350 t at Kg 9.10 m, 4.00 m to starboard of the centreline Discharge 918 t of ballast from Kg 2.00 m, the tank is on the centreline. The tank remains slack and the FSM caused by this slack tank is 1600 t-m.

Using Datasheet Hydrostatic Particulars, calculate the list on completion of operations.

(b) Using Worksheet Q2(b) GZ Curve, label and determine EACH of the

following:

(i) the approximate initial GM; (ii) the approximate angle of deck edge immersion;

(iii) the angle of vanishing stability;

(iv) the maximum GZ value and the angle at which it occurs;

(v) the range of positive stability.

SECTION A

1. A vessel LBP 100 m is loading in a Winter North Atlantic port, in winter, in dock water (RD 1.015). The vessel is upright at an even keel draught with the waterline 450 mm below the upper edge of the summer loadline. The vessel has a Summer draught of 8.800 m. The vessel is to be fully loaded so that she will be on the correct mark in open sea (ignoring the effects of fuel consumption for the passage to sea). Using Datasheet - Hydrostatic Particulars, calculate EACH of the following: (a) the sinkage required in port in order that the vessel will be fully loaded; (b) assuming a mean TPC (salt water) of 24.07 t (constant), the maximum

weight of cargo still to load;

(c) the vessel’s displacement on sailing.

2. (a) A vessel floating upright in salt water, is at anchor at a displacement

12700 t and KG 7.00 m. There are TWO heavy lifts on deck at the following positions. 75 t at Kg 14.50 m, 12.00 m to port of the centreline. 125 t at Kg 18.90 m, 11.00 m to starboard of the centreline. The 75 t lift will be discharged into a barge on the port side. The 125 t lift will be discharged into a barge on the starboard side. Both heavy lifts will be discharged using the vessel’s own crane. The head of the crane is at 32.00 m above the keel and each barge is 18.00 m off the centreline. Using Datasheet - Hydrostatic Particulars, calculate the maximum list during the discharge, after the 75 t weight on the port side has been discharged first. (b) Using Worksheet Q2 - GZ Curve, determine EACH of the following: (i) the condition of stability of the vessel; (ii) range of positive stability; (iii) angle of vanishing stability; (iv) approximate initial GM (indicate on the graph how this value has been obtained). (c) Using Worksheet Q2, calculate the righting moment at an angle of heel of

30 degrees if the displacement is 15500 t.

5. (a) With reference to MARPOL 73/78 Annex II (as amended):

(i) list the operational standards for discharges of noxious liquid substances of categories X, Y or Z when the vessel is at sea;

(ii) state which record book is required to be kept by a vessel carrying

noxious liquid substances in bulk. (b) With reference to MARPOL 73/78 Annex IV (as amended), state the criteria that must be complied with for discharge of sewage. (c) With reference to MARPOL 73/78 Annex VI (as amended): (i) list the emissions which are regulated by the convention; (ii) list THREE substances which must not be incinerated on board.
