1. The following cargo tanks are piped for either crude oil or clean sea water ballast (after crude oil washing):Cargo Tank No. 6 P, S, & CLCargo Tank No. 7 P&SCargo Tank No. 8 CLCargo Tank No. 9 CL

2. The above-noted tanks are NOT to be used for either products cargo or sea water ballast when carrying products.

3. A light ship plus clean sea water ballast condition Is included herein to demonstrate compliance with the requirements ofRegulation 13A of the International Conference on Tanker, Safety and Pollution Prevention, 1978.

4. The Products Loading Conditions herein are predicated on a maximum draft at bow or stern of 38.50' for transit of the Panama Canal.

INSTRUCTIONS FOR COMPLETION OF TRIM AND STABILITY LOADING CONDITION FORMS

1. Blank forms for calculation of trim and stability for conditions not covered by this booklet are:Sheet 81A Summary Sheet

81B Details of Ship's Deadweight81C Details of Cargo Loading81D Details of Sea Water Ballast

2. Enter weights and free surface on Sheets 81B, 81C and 81D as applicable. Compute moments and totals and enter on SummaryForm, Sheet 81A, and compute summary totals. Take care to enter longitudinal moments as + for Aft, – for Forward.

3. For the displacement, Sheet 81A, read mean draft from Sheet 7, Curves of Form. At this draft, read Curves of Form data for KM, LCB, MT 1" andLCF. Enter these data on Sheet 81A.

4. Transverse StabilitySubtract the total VCG (=KG) from KM to obtain the GM uncorrected for free surface. Divide the total free surface by the displacement toobtain the free surface correction and subtract this value from the uncorrected GM. The final result is the GM corrected for free surface,which must be at least 1.2 FT (to suit max req'd weather criteria GM at IMCO Ballast Draft per superseded Stability Booklet).

5. TrimSubtract the total LCG from the LCB to obtain the trimming lever. Trim is by stern if LCG is aft of LCB and by bow otherwise. Compute trim bymultiplying displacement by trimming lever and dividing by product (MT1 x 12”). For drafts of 32 FT or greater and/or small trim, the effectof LCF on trim is small and forward and aft drafts can be computes by adding or subtracting (to suit trim by bow or stern) half the trim fromthe mean draft. For large trim at drafts less than 32 feet compute draft at bow = mean draft - trim X (352.5 – LCF) / 705. The draft & LCF valuesare treated algebraically; i.e., the minus signs in the expression change to plus for trim by bow and/or LCF aft of amidships. Draft at stern isdraft at bow – trim.

SHEET 2


INSTRUCTIONS FOR COMPLETION OF FORMS TO DETERMINE HOGGING AND SAGGING NUMERALS

1. Sheet 81E is the form for computing longitudinal bending stress numerals. The resulting numeral should not exceed 100.

2. The weights entered on Sheets 81B, 81C and 81D, divided by 100 and as applicable, are entered in the “Tons/100” column ofSheet 81E for departure and arrival conditions. Multiply the “Tons/100” by the Hogging and Sagging Factors for all weightsentered in lines 1–27 and enter totals on line 28, “Total Deadweight.”

3. Line 29 gives the light ship value for “Tons/100” and the associated hogging and sagging numerals. The light ship valueincludes weights for spare tailshaft and stowage as given on Sheet 81B ([12821 + 29] / 100 = 128.50). Add lines 28 and 29 toobtain line 30 displacement and hogging and sagging numerals for departure and arrival conditions.

4. Enter the “Tons/100” deadweight from line 28 in line 31 “Numeral” columns for both hogging and sagging, and subtract fromline 30. The resulting values in line 32 must not exceed 100.

1. To obtain the free surface correction to GM in any condition of loading, add the I/δ values of all slack tanks and divide by thedisplacement of the vessel.

2. Values of I/δ for different API cargo may be obtained by either dividing tabular values of I(FT4) by corresponding density of

cargo in tank, or by interpolation.

AVERAGE TEST WEIGHT OF THE PRINCIPAL GRAINS LOADED AT UNITED STATES PORTS

The test weight of a particular grain is the actual weight in pounds of a U.S. (Winchester)bushel which is a unit of volume (dry measure) equaling 2,150.42 cubic inches or 1.2445cubic feet.
