INSTRUCTIONS FOR DETERMINING STABILITY, TRIM, AND HEEL

Long Method

Displacement, Center of Gravity, and Free Surface Moment:

Displacement, center of gravity, and free surface moment of a proposed loading condition is determined using the blank Loading Summary and Tankage Loading

Table sheets as follows. Detailed weights and centers of gravity must be identified for all deadweight on board including liquids in tanks, stores, mission load items, and deck cargo.

1. Liquids in tanks.

a. For each non-empty tank enter the tank's load fraction (percent full value) on the Tankage Loading Table sheet.

b. Using the tank's load fraction calculate the weight as follows:

(1) Divide the load fraction percentage by 100 to obtain a decimal value.

(2) Multiply the decimal value load fraction by the 100% capacity in gallons on the Tank Capacity Table on sheet 18 to obtain the tank's load in gallons.

e e A

-S

E P -2

SHEET 5

(3) Divide the tank's load in gallons by the density in gallons per ton from the Table of Equivalents on sheet 3 to obtain the weight of the tank's load.

c. Free surface moment.

(1) For all empty tanks enter 0 (zero) in the FS Mom column on the

Tankage Loading Table sheet.

(2) For all tanks, except fresh water tanks, which are 100% full enter 0

(zero) in the FS Mom column on the Tankage Loading Table sheet. For fresh water tanks that are 100% full enter the Slack FS Mom value from the Tank Capacity Table on sheet 18, except for Full Load

Departure conditions enter 0 (zero).

(3) For all tanks that are slack (less than 95% full) enter the Slack FS

Mom value from the Tank Capacity Table in the FS Mom column on the

Tankage Loading Table sheet.

The following tanks should be considered slack in all loading conditions except Full Load Departure.

Fuel Oil Day Tank

Potable Water Tank 5P

Potable Water Tank 5S

(4)For all other tanks enter the Full FS Mom value from the Tank

Capacity Table in the FS Mom column on the Tankage Loading Table sheet.

d. Multiply the weight by the VCG, LCG, and TCG to obtain the vertical moment (VMOM), longitudinal moment (LMOM), and transverse moment (TMOM) for each tank.

e. For each liquid type (diesel oil, SW ballast, fresh water, lube oil, or misc) sum the weight, VMOM, LMOM, TMOM, and FS Mom. Divide the sum of

VMOM, LMOM, and TMOM by the sum of the weight to obtain the total VCG, LCG, and TCG.

If the total FS mom for each liquid type is less than the minimum value listed below enter the minimum FS Mom value from the list below in place of the computed value.

Fuel Oil 136.60

Fresh Water 57.00

Lube Oil 0.10

Hydraulic Oil 0.20

f. Copy the sum of the weight, VCG, LCG, TCG, and sum of VMOM, LMOM, TMOM, and FS Mom for each liquid type (diesel oil, SW ballast, fresh water, lube oil, or misc) to the appropriate line on the Loading Summary sheet.

2. Stores.

Enter the percent load for PROVISIONS & STORES. Calculate the weight of stores as:

PROVISIONS & STORES weight = percent load * 15.78 / 100

Multiply the weight by the VCG, LCG, and TCG to obtain the vertical moment

(VMOM), longitudinal moment (LMOM), and transverse moment (TMOM).

3. Mission load items.

NOAA Ship Oregon II operates with many different mission configurations.

Mission load breakdowns for these mission loads are shown on sheets 22 through 60.

E P -2

SHEET 6

If the proposed loading condition includes one of the standard mission loads, for which a breakdown is shown on sheets 22 through 60, copy the total weight, VCG, vertical moment (VMOM), LCG, longitudinal moment (LMOM), TCG, and transverse moment (TMOM) to the MISSION LOAD line on the Loading

Summary sheet.

Mission load item values for other mission configurations can be determined using the Mission Load Worksheet (sheet 61) as follows:

a. Place a check mark in the "On Board" column next to any standard item to be carried.

b. Copy the weight of all checked items to the "LOAD" column.

c. Under "OTHER ITEMS" list all non-standard mission load items such as scientific equipment, extra mission related spare parts, and the like.

Include each item's weight in the "LOAD" column and each item's VCG, LCG, and TCG in the associated column.

d. Calculate each load's vertical moment, longitudinal moment, and transverse moment by multiplying its weight by its VCG, LCG, and TCG respectively.

e. Sum all entries in the "LOAD", vertical moment, longitudinal moment, and transverse moment columns to obtain the total mission load weight and moments.

f. Divide the total vertical moment by the total weight to obtain mission load VCG. Divide the total longitudinal moment by the total weight to obtain mission load LCG. Divide the total transverse moment by the total weight to obtain mission load TCG.

g. Copy the total weight, VCG, vertical moment (VMOM), LCG, longitudinal moment (LMOM), TCG, and transverse moment (TMOM) to the MISSION LOAD line on the Loading Summary sheet.

4. Miscellaneous deadweight.

a. Enter miscellaneous deadweight load information not covered elsewhere on the Loading Summary sheet. These items could include additional scientific equipment, miscellaneous project gear, and the like. The information needed is: description, weight, vertical center of gravity

(VCG), longitudinal center of gravity (LCG), and transverse center of gravity (TCG). If the miscellaneous deadweight load item contains a liquid loading the free surface moment (FS Mom) is also needed.

b. Calculate each load's vertical moment (VMOM), longitudinal moment

(LMOM), and transverse moment (TMOM) by multiplying its weight by its

VCG, LCG, and TCG respectively.

5. Sum all weights, vertical moments, longitudinal moments, transverse moments, and free surface moments on the Loading Summary sheet, including light ship values.

The sum of weights is the proposed loading condition's displacement

(DISPL).

The sums of moments are the proposed loading condition's total vertical moment (VMOM), total longitudinal moment (LMOM), total transverse moment

(TMOM), and total free surface moment (FS Mom).

6. Divide the total vertical moment (VMOM) by the displacement (DISPL) to obtain the proposed loading condition's VCG. Divide the total longitudinal moment (LMOM) by the displacement (DISPL) to obtain the proposed loading condition's LCG. Divide the total transverse moment (TMOM) by the displacement (DISPL) to obtain the proposed loading condition's TCG.

SHEET 7

Trim:

Trim and drafts of a proposed loading condition are determined using the blank

Loading Summary sheet as follows (before trim and drafts can be determined the proposed loading condition's displacement (DISPL) and total longitudinal center of gravity (LCG) must be determined using the methods previously presented):

1. Using the proposed loading condition's displacement (DISPL) find the baseline mean draft (Tm), longitudinal center of buoyancy (LCB), longitudinal center of flotation (LCF), and longitudinal metacenter height above baseline (KML) from the table of Hydrostatic Properties on sheet 16.

Intermediate values can be determined by interpolation.

2. Calculate the trimming lever (TL) as:

TL = LCG - LCB

3. Calculate the moment to alter trim one inch (MT1) as:

MT1 = (KML - VCG) * DISPL / (12 * LBP) NOTE: LBP = 152.00

4. Calculate TRIM.

The moment causing the vessel to trim is the displacement (DISPL) multiplied by the trimming lever (TL). This trimming moment divided by 12 times the MT1 gives the total trim in feet. Trim will be forward (-) if LCG is forward of LCB and aft (+) if the opposite is true.

TRIM = (DISPL * TL) / (12* MT1)

5. Determine drafts.

Keel drafts at the forward draft marks (DMfwd), and at the aft draft marks

(DMaft) are found as follows (all dimensions are in feet).

Tf = Tm + TRIM( 4.55 – LCF)/LBP) – 2.80’ NOTE: LBP = 152.00

Ta = Tm + TRIM(143.00 - LCF)/LBP) – 0.17’

The deepest navigational draft are found as follows.

Tnav = Tm + TRIM(152.14 – LCF)/LBP) NOTE: LBP = 152.00

Stability:

Stability characteristics of a proposed loading condition are determined using the blank Loading Summary sheet as follows (before stability characteristics can be determined the proposed loading condition's Displacement (DISPL), total vertical center of gravity (VCG), and total free surface moment (FS Mom) must be determined using the methods presented above):

1. Using the proposed loading condition's displacement (DISPL) find the baseline mean draft (Tm) and the transverse metacenter height above baseline

(KMt) from the table of Hydrostatic Properties on sheet 16. Intermediate values can be determined by interpolation.

2. Calculate the uncorrected metacentric height (GM) as:

GM = KMt – VCG

4. Calculate the free surface correction (FS Corr) as:

FS Corr = FS Mom / DISPL

5. Calculate the available metacentric height (GM Available) corrected for free surface as:

GM Available = GM – FS Corr e e A

B S H o u s to n L e tt e r R e f D a te d

-S

E P -2

SHEET 8

6. Using the baseline mean draft (Tm) find the minimum GM Required from the graph of GM Required Curves on sheet 17.

7. Compare the GM Available to the minimum GM Required by calculating the GM

Margin as follows:

GM Margin = GM Available – GM Required

The GM Margin must be positive (greater than zero) at all times.

Heel:

Heel (list) of a proposed loading condition is determined, if desired, using the blank Loading Summary sheet as follows (before heel can be determined the proposed loading condition's displacement (DISPL), GM Available, and total transverse moment (TMOM) must be determined using the methods previously presented):

1. Calculate the heeling moment that would cause one degree of heel (MH1) as:

MH1 = 0.01745 * GM Available * DISPL

2. Calculate the angle of heel by dividing the total transverse moment (TMOM) by MH1. Port heel is indicated algebraically by (-), starboard by (+).

Short Method:

Stability:

For minor changes from any tabulated loading condition (sheets 22 through 60), the GM Available may be determined by applying GM corrections set forth in the tables on sheet 15. This method is fast and reasonably accurate in evaluating a loading condition that is similar to one of the representative conditions shown in this booklet.

Trim:

The effect on trim of minor changes from the representative loading conditions can be estimated from the trim diagram on sheet 13. This method is sufficiently accurate for practical purposes in predicting trim for a loading condition that is similar to one of the representative conditions shown in this booklet.

DETERMINING DISPLACEMENT AND TRIM FROM OBSERVED DRAFTS

The ship's displacement and trim can be determined from observed draft mark readings using the draft diagram on sheet 14. Instructions are provided on the diagram. The draft diagram must be used with the average of port and starboard draft readings to eliminate the effect of heel.

ROUTINE OPERATING INSTRUCTIONS

1. Once suction has been taken on a pair of diesel fuel tanks, continue pumping from that pair until they are empty before taking suction on another pair of fuel tanks. As the vessel goes below 50% fuel capacity it may be necessary to use the fuel tanks to maintain a close to zero heel angle.

2. Bilges and drain wells in machinery spaces shall be kept pumped to minimum content at all times.

4. Deck freeing ports shall be maintained operable and completely free of obstruction at all times.

e e A

B S H o u s to n L e tt e r R e f D a te d

-S

E P -2

SHEET 9

5. Any openings that could allow water to enter into the hull or deckhouse should be kept closed when rough weather or sea conditions exist or anticipated.

6. Every effort shall be made to determine the cause of of any list of the vessel before taking corrective action. If list is found to be caused by damage follow the procedures indicated in the “Action Following Damage” section below.

7. Seawater Ballast:

a. Ballast tanks should normally be slack only when filling or emptying. When not ballasted, all seawater tanks shall be pumped periodically to assure minimum content at all times.

b. During ballasting and deballasting, a reduction in the vessel's GM due to slack free surface will occur until the tanks are pressed up. This temporary loss of GM is equal to the seawater free surface moment of the tank (or tanks), divided by the vessel's displacement at the time of ballasting or deballasting.

c. When seawater ballast must be added during a voyage, prudent operation dictates that it should be added well in advance of drawing fuel. Therefore, compensating seawater ballast should be introduced and pressed up prior to the drawing of fuel to minimize free surface loss and ensure adequate stability at all times.

8. No more than two of the following lifting devices may be used simultaneously; J-

Frame, Fore Deck Boom Crane, and Aft Deck Boom Crane. The Rescue Boat Davit is only to be operated when no other lifting devices are in operation.

9. The following tank use sequence may be used as a guideline to minimize trim, heel, and to insure adequate for the known mission configurations. The points of Available GM on sheet 17 conform to these sequences. Note that ballasting of the forepeak and after peak ballast tank, when not filled at departure, should be started no later than after emptying diesel fuel tank No. 7P, in order to maintain a good margin of GM in excess of the minimum required GM.

Earlier ballasting to help trim angle and or to assist in sea conditions may be necessary.

TANK USE INSTRUCTIONS

In order to maintain positive GM margin and to avoid immersing the Plimsoll

Mark the following sequences of burning from fuel oil tanks and filling ballast tanks is recommended. The Fuel Oil Day Tank is considered 95% at departure, then maintained 50% full at all times throughout the remainder of the voyage for both sequences. Fresh Water tanks are kept at 100% capacity throughout the voyage in these sequences. It is acceptable to burn from port and starboard fuel tank pairs unevenly in order to mitigate any excessive heel as is adjusting fresh water tank levels.

Departure Condition: DO storage tanks at 95%

SW ballast tanks at 51% (Aft Peak @ 100%)

Fresh Water tanks at 100%

Lube and Hydraulic oil at 95%

(1) Burn from Number 2 DO Tanks until empty

(2) Burn from Number 7 DO Tanks until empty

(3) Burn from Number 3 DO Tanks until vessel trims 1.25’ aft

(4) Ballast Forepeak Tank until 100% capacity e e A

SHEET 10

(5) Burn from Number 3 DO Tanks until empty

(6) Burn from Number 4 DO Tanks until arrival (see load sheet)

This sequence was developed to for the loading conditions shown on sheets 25 through 60. When operating in a loading condition other than shown on sheets 25 through 60 these sequences may be used as a guideline to insure adequate stability down to the appropriate arrival condition.

ACTION FOLLOWING DAMAGE

Most of the foregoing discussion applies to the intact properties of the vessel. In the event of underwater damage or entry of water through the weather envelope, stability and trim will be affected by the consequent flooding of spaces within the vessel.

While there are no regulatory criteria in the case of this vessel for subdivision or for stability after damage, the following should be noted.

The response of the vessel to flooding will depend on the draft, intact trim, and stability characteristics existing immediately prior to the incident, and the condition of the tanks, if any, involved in the flooding. The routine operating instructions tabulated above are designed to reduce the trim and list resulting from such flooding and to reduce the amount of corrective action to be taken in the inevitable period of confusion following such an incident.

Entry of a significant amount of water into any part of the vessel should be regarded as an emergency situation and appropriate measures should be taken promptly. These would normally include the following:

1. Call for assistance.

2. Alert vessel personnel to the situation.

3. Favor stability in handling the vessel. Head into the wind and seas if possible. Avoid hard turns.

4. Determine the source of flooding and the spaces affected or likely to be affected.

e e A

B S H o u s to n L e tt e r R e f D a te d

-S

E P -2

SHEET 11

5. Activate the bilge system, emergency generator, and other emergency systems as required.

6. Establish flooding boundaries by shoring or patching, to prevent or limit progressive flooding.

In general, if trim and list reach a steady state with no further increases, chances of survival will be good. Further action will depend upon the degree of improvement in the vessel's attitude deemed necessary in the circumstances. For example, if the main deck aft is heavily awash, trimming by the head may be considered. If the vessel lists heavily as a result of unsymmetrical flooding, list correction may be undertaken.

Trim and list correction should generally be made by shifting liquids already on board rather than by taking on water ballast, which will increase the draft and reduce the reserve buoyancy. When shifting liquids, the following precautions should be observed:

1. DO NOT attempt to correct a list by shifting liquids if any of the signs of negative GM are present. These signs include:

a. a slow, erratic period of roll;

b. failure to return to upright after rolling to one side; and

c. listing alternatively to port and starboard.

2. If, and only if, it can be positively determined that a list is due to unsymmetrical flooding and that the vessel has a positive GM, list correction by shifting of liquids may be undertaken slowly and cautiously.

3. Take suction from tanks which are already slack rather than tanks that are full. This will minimize the increase in free surface effect.

4. Discharge to tanks which are slack, rather than empty, and preferably those that are nearly full. Press up into vent lines.

5. Favor improvements of trim, if possible, when selecting tanks for transfer.

Minor improvements in stability may also be accomplished by lowering movable weights. For example, cranes, if initially up in the working position, may be lowered to the fully-down position. In cases where survival takes precedence over all other considerations, heavy gear may be jettisoned, working from the upper decks down. Jettisoning is a slow and laborious operation and the improvement obtained will usually be small, therefore, it should be considered only in an extreme situation.

PERIOD OF ROLL

The natural period of roll of a vessel is inversely proportional to the GMt in any particular loading condition. The equation below indicates the approximate relationship between GMt and period of roll for NOAA Ship Oregon II, and may be used to estimate the GMt when roll period can be measured. Such a measurement should only be made under relatively calm conditions when roll is fairly regular and at constant small amplitude. When measuring roll period always measure the time for several rolls and divide by the number of rolls observed. The period of a complete roll, such as port to starboard and back to port, must be used with the equation.

GM = (558.14)/T

2; T = Period of Roll

Estimating GMt from the roll period is a means of checking only. It is not intended to take the place of the calculations described on sheets 4 through 8.

EFFECT OF ICING ON GM AVAILABLE

Any accumulation of ice topside will cause a reduction in GM Available. An approximation of this loss may be obtained by estimating the average thickness of ice over all of the exposed areas above the waterline, including masts, J-frame, rails, rigging, etc, as well as bulkheads and decks. Based on IMO and USCG guidance it is assumed that ice build-up on horizontal surfaces will be twice the thickness of build-up on vertical surfaces.

The effect of topside icing on GM Available is shown on the graph on sheet 20, where the curve of GM Required is repeated from sheet 17. Ice accumulation of the following thickness is shown on the chart. Other ice thicknesses will have proportional effects.

Ice thickness Added weight VCG LCG TCG

Horiz (in) Vert (in) (L tons) (feet) (feet) (feet)

1.30 0.65 28.06 23.31 59.45 0.67

0.65 0.32 13.92 23.35 59.51 0.68

The magnitude of the loss in GM Available indicates that significant accumulation of ice can result in a deficient stability condition. Conditions favorable to ice formation should be avoided when possible. When arrival in sheltered waters is not imminent, stability improvement measures should be considered and ice removal procedures should be initiated early so that substantial amounts do not accumulate.
