200. NOTES TO MASTER This Stability Document is based on an inclining experiment of the subject vessel performed on July 24th, 2015 at Eregli Shipyard, Turkey. (see Section 300). This stability document is in compliance with the following:

- Bureau Veritas Rules - Part B, Chap. 3, Sec. 2.2 - Intact Stability - IMO IS Code (2008) - Part A, Chap. 2, 2.2 – General Intact Stability - Bureau Veritas Rules - Part B, Chap. 3, Sec. 2.3 - Weather Criterion - IMO IS Code (2008) – Part A, Chap. 2, 2.3 – Weather Criterion - Bureau Veritas Rules - Part D, Chapter 14, Section 2.2 - Tug Stability - Bureau Veritas Rules - Part D, Chap. 16, Sec. 2.1 - Fi-Fi Stability

It must be emphasised that the conditions provided in this booklet are only to be regarded as guiding conditions. Immediately before the start of a new voyage the master has therefore to determine the vessel's trim and stability to ensure that all requirements concerning the stability are fulfilled. Since the lightship TCG is 36mm off centreline to starboard side, in order to reduce the list at departure condition, the starboard fresh water tank is limited to 60% full at depar-ture condition. The load draft is advised to be less than 3.002m, which is the maximum draft of the loading condition that was checked with all stability criteria in section 207. FO_aft.S, FO_fwd.S and FW.S tanks are empty and port side of these tanks are filled 20% in order to reduce the list at arrival loading conditions. Aft and fore peak tanks are not used in any loading conditions. For towing condition:

When engaged in towing, large external heeling moments may be applied to the tug especially if the tow lead forms a large angle with the horizontal axis of the tug. Such a condition would be further aggravated in adverse conditions of weather and tide and could produce a dangerous condition which might eventually result in the tug capsizing. At the commencement of a tow it is important to ensure that the load placed upon the tow line and towing winch is applied gradually, particular regard being taken of the relative thrust of the tug and the resistance of the tow. For towing operations only the departure and arrival conditions are presented in this book, and compliance with BV criteria has been assessed. As such, towing operations should only be conducted between these two drafts (loadings), and should not be under-taken at the deeper load drafts.

Page 11 of 123



The stability criteria contained in this report set minimum values, but no maximum values are recommended. It is advisable to avoid excessive values of metacentric height, since these might lead to acceleration forces which could be prejudicial to the ship, its complement, its equipment and to safe carriage of the cargo. Slack tanks may, in exceptional cases, be used as a means of reducing excessive values of metacentric height. In such cases, due consideration should be giv-en to sloshing effects. Operational precautions in heavy weather All doorways and other openings, through which water can enter into the hull or deckhouses, forecastle, etc., should be suitably closed in adverse weather conditions and accordingly all ap-pliances for this purpose should be maintained on board and in good condition. Weathertight and watertight hatches, doors, etc., should be kept closed during navigation, except when necessarily opened for the working of the ship and should always be ready for immediate closure and be clearly marked to indicate that these fittings are to be kept closed except for access. Hatch covers and flush deck scuttles in fishing vessels should be kept properly secured when not in use during fishing operations. All portable deadlights should be maintained in good condition and securely closed in bad weather. Any closing devices provided for vent pipes to fuel tanks should be secured in bad weather. Ship handling in heavy weather In all conditions of loading necessary care should be taken to maintain a seaworthy freeboard. In severe weather, the speed of the ship should be reduced if propeller emergence, shipping of water on deck or heavy slamming occurs. Special attention should be paid when a ship is sailing in following, quartering or head seas be-cause dangerous phenomena such as parametric resonance, broaching to, reduction of stability on the wave crest, and excessive rolling may occur singularly, in sequence or simultaneously in a multiple combination, creating a threat of capsize. A ship.s speed and/or course should be al-tered appropriately to avoid the above-mentioned phenomena. Reliance on automatic steering may be dangerous as this prevents ready changes to course which may be needed in bad weather. Water trapping in deck wells should be avoided. If freeing ports are not sufficient for the drain-age of the well, the speed of the ship should be reduced or the course changed, or both. Freeing ports provided with closing appliances should always be capable of functioning and are not to be locked. Masters should be aware that steep or breaking waves may occur in certain areas, or in certain wind and current combinations (river estuaries, shallow water areas, funnel shaped bays, etc.). These waves are particularly dangerous, especially for small ships. In severe weather, the lateral wind pressure may cause a considerable angle of heel. If anti-heeling measures (e.g., ballasting, use of anti-heeling devices, etc.) are used to compensate for heeling due to wind, changes of the ship.s course relative to the wind direction may lead to dan-gerous angles of heel or capsizing. Therefore, heeling caused by the wind should not be compen-sated with anti-heeling measures, unless, subject to the approval by the Administration, the ves-sel has been proven by calculation to have sufficient stability in worst case conditions (i.e. im-

Page 12 of 123



proper or incorrect use, mechanism failure, unintended course change, etc.). Guidance on the use of anti-heeling measures should be provided in the stability booklet. Use of operational guidelines for avoiding dangerous situations in severe weather conditions or an on-board computer based system is recommended. The method should be simple to use.

201. Notes on Stability Calculation Methods

The results presented in this Stability Booklet been calculated using GHS software.

GHS is an advanced naval architectural software program which produces accurate results based on individual hydrostatics calculations for each condition rather than on the traditional method of using tabulated Hydrostatics and Cross-Curves values applied to a weight total.

For this reason, a possible cross-check of the results presented in this Stability Booklet with the tabulated Hydrostatics and Cross-Curves from Section 500 may result in slight discrepancies, in particular:

- trim obtained from BG, Displacement, and MCT values for each condition may differ

from the actual Trim value therein, since the program takes into account the shift of liquids in tanks due to trim, as well as calculating the actual LCB of the hull at the trim angle for each loading condition

- similarly the Righting Levers (GZ) shown in the presented conditions may differ from that obtained by using KG, Free Surface, and tabulated KN values since the program takes into account the actual shift of liquids in tanks due to heel (and trim) as well as calculating an actual Centre of Buoyancy for each heel angle. The difference between actual free surface shift and the traditional calculation can be very significant for large tanks at large heel an-gles due to "topping" of the tank. The effect that trim can play on Righting Levers can al-so be significant at large angles of heel, particularly upon deck edge submergence.

In view of the above, it should be understood that the Hydrostatics and Cross-Curves included in this Stability Booklet, as required by the Regulatory Bodies, can be used in the traditional manner, but may produce slightly different results when applied to conditions presented herein. The volume for Hydrostatics and KN calculations have included all buoyant bodies – hull, skeg and two Z-Drivers, and deducted Box cooler (P&S) and Fi-Fi Sea Chest (P&S), in GHS model, Bottom plate is 8mm, shell thickness is 10mm, skeg bottom plate is 12mm.

202. Good Seamanship

Compliance with the stability criteria does not ensure immunity from capsizing, nor absolve the Master from his responsibilities. The Master should therefore exercise prudent judgement and

Page 13 of 123



good seamanship having regard for the season, weather forecast and navigational zone; and should take the appropriate action as to speed and course depending on the prevailing circum-stances.

Care should be taken that the cargo allocated to the ship is capable of being stowed so that com-pliance with the criteria can be achieved. If necessary, the amount should be limited to the ex-tent that ballast weight may be required.

Before a voyage commences, care should be taken to ensure that any sizeable pieces of equip-ment have been properly stowed and/or lashed, to minimize the possibility of both longitudinal and transverse shifting due to rolling and pitching accelerations while at sea.

A ship, when engaged in towing operations, should not carry deck cargo, except that a limited amount, properly secured, which would neither endanger the safe working of the crew on deck nor impede the proper functioning of the towing equipment, may be acceptable. The number of partially filled or slack tanks should be kept to a minimum due to their adverse effect on stability.

203. Alternative Conditions

When actual loading conditions differ from those included in this Stability Booklet, calculate the vessel's stability to assure that an adequate margin of safety is maintained with respect to compliance with the minimum regulatory requirements of Section 207.

The sample calculations in Section 700 are intended to aid personnel in determining with long-hand methods the trim, stability, and heel characteristics for specific conditions which may vary from those included in this Booklet. These calculations will be provided in the Final Stability Booklet.

204. Down-Flooding Points

The angle of down-flooding for each intact condition is given on the condition sheets. The down-flooding points are:

206. Notes on Free Surface

When tanks are completely full or empty, no movement of the liquid is possible and so no ef-fect on the vessel's stability occurs. When tanks are partially filled the stability of the vessel is adversely affected by what is known as "FREE SURFACE EFFECT". This effect on vessel's stability is traditionally re-ferred to as a "loss in GM" or as a "virtual rise in KG". As per the BV Rules Part B, Chapter 3, and Section 2.4 – Effects of Free Surfaces of Liquids in Tanks, the corrections to the initial metacentric height (GM) and to the righting lever curve (GZ) are calculated separately as follows:

-In determining the correction to GM, the transverse moments of inertia of the tanks are to be calculated at 0 degrees angle of heel according to the tanks’ categories. For tanks with fixed filling level, the free surface correction is to be defined for the actual filling level to be used in each tank. For tanks with variable filling level, the free surface correction is to be the maximum value attainable among the filling limits envisaged for each tank, con-sistent with any operating instructions. For each type of consumable liquid, the maximum free surface correction was applied to at least one pair of wing tanks or one centreline tank and all large tanks as defined by BV Rules Part B, Chapter 3, Section 2.4 - The righting lever curve (GZ) was corrected by the actual moment of fluid transfer for each angle of heel calculated

207. Minimum Standards for Intact Stability

700. SAMPLE STABILITY CALCULATION

The following example calculations represent the manual method forcalculating stability conditions, other than those presented in section 400,from the data provided in this book.

Condition #2: Departure Condition at 3.002m Draft

701. Draft and Trim

A) Draft Readings: Fwd Aftport 3.616 4.787 mstbd 3.652 4.851 m

Reference point of fwd draft marks is 0.706 m under baseline @Fr36Reference point of aft draft marks is 1.763 m under baseline @Fr5

B) Corresp Drafts Above Base: Fwd Aftport 2.910 3.024 mstbd 2.946 3.088 mmean 2.928 3.056 m

Mean hydrostatic draft = (Da+Df)/2= (2.928+3.056)/2 = 2.992 m above baseline

Trim = Da - Df = 3.056-2.928 = 0.128 m aft (between marks)

C) Draft at LCF:The LCF draft is calculated using proportional triangles.

Approximate location of LCF (based on Sec. 500 Hydrostatic tables) 1.079 diff1 diff2Location of aft draft reading 9.150 8.071Location of fwd draft reading -9.760 10.839Total distance between readings 18.910(distances measured from midships, positive aft of midships)

If trim is by the stern: Draft at LCF = draft fwd + (diff2*trim)/dist between readings

If trim is by the bow: Draft at LCF = draft aft + (diff1*trim)/dist between readings

Therefore:Draft at LCF = 2.928+10.839*0.128/18.91 3.001 metres above base line

Page 102 of 123


702. Displacement and Hydrostatics

Displacement and hydrostatic information is obtained from the datacontained in section 500 as follows:

LCF draft = 3.00 m Disp = 390.78 Mt VCB = 1.835 m KMt = 4.884 m MCT = 2.920 Mt-m/cm LCB = 0.624 m LCF = 1.079 m (note: hydrastatic data from section 500)

703. Calculate LCG

Trimming Moment = Trim (cm) * MCT /1 cm = 0.128*2.920*100 = 37.38 Mt-m

If trim aft:LCG = LCB + (trim moment / disp)

If trim fwd:LCG = LCB - (trim moment / disp)

Therefore:LCG = 0.624+37.38/390.78LCG = 0.72 m

704. Free Surface Corrections

Free surface moments for the various tanks are provided in the tank calibrationtables (section 600).

From these tables the tank loads, centers, and free surface correctioncan be obtained.

Free surface correction (Fsc) = total free surface moment / displacement of vessel

The free surface correction is then applied as a virtual rise in the centerof gravity; KGf = KGs + Fscor as a reduction in metacentric height. GMf = GMs - Fsc

706. Calculation of Angle of Downflooding

As mentioned in section 204 the downflooding points are considered to bethe engine room air intake louvre P&S and the engine room relief air louvre P&S.

Before the righting areas are calculated for any stability condition,the angle of downflooding should be determined. If the angle of downflooding occurs at some angle less than 40 degrees, then thethe righting areas will be calculated to this angle as mentioned insection 207.

Based on Vessel draft vs downflooding angle, at 3.001m draft at 0.128m aft trim. The downflooding point is 39.28 degs

Since the downflooding angle is 39.28 degs, less than 40 degrees, it is necessary to determinethe area under the RA curve to 39.28 degs

707. Calculation of Righting arms

KG = 2.93 mFsc = 0.07 mKGf = KG+FSC= 3.00 m

Obtain KN values, at heel increments, from cross curves in section 500.Then calculate GZ = KN - KGf X SIN(theta)

Areas under the GZ curve (see next page) are determined using Simpson's firstrule from 0-40 degrees and the trapezoidal rule from 30-40 degrees.

Thus: Area 0-40 = 1/3*h*(sum of area products)h = increment between heel angles (i.e. 10 deg.)

Area 30-40 = 10*1/2*(GZ @ 30 deg + GZ @ 40 deg)
