1. 115000 DWT CRUDE CARRIER2. SPEED: 14 KNOTS3. DISTANCE:12000 nm
PORT OF ORIGIN:
Puerto José is a sea port in northeastern Venezuela, on the Caribbean Sea, in the state of Anzoátegui[1], about 10km west of Barcelona. Position: 10°06' N / 64°52'W. It is home to an important oil tanker loading complex, the Complejo criogenico de Oriente José, created in 1985[2] and now more often referred to by its original name, the Cryogenic Complex of Oriente, San Joaquin Plant. The complex is used to load several of Venezuela's petroleum products onto oil tankers, including Ameriven-Hamaca, Cerro Negro, Sincor, and Zuata Sweet.
The José industrial zone comprises one part of the Eastern Cryogenic Complex (ACCRO), which includes refineries, petrochemical plants, and gas compression plants[3]. The complex consists of several separate terminals on the South side of Bahía de Barcelona. The port exports refined petroleum products, crude oil and containers. About 180 ships with a total of 30 million tons deadweight (tdwt) are using the port every year.
The deepest and longest berth is the Petroterminal José (TAECJ Terminal). Ships up to 300,000 tdwt can berth at the Bitor Single Point Mooring buoy (SPM, 10°09'N / 64°50'W). The complex consists further of a cryogenic jetty terminal (10°05.08'N / 64°51.5'W), two petrochemical docks (Petrozuata and SINCOR), an offshore platform terminal, and two SPM's. The offshore terminal and the SPM are connected to the shore by submarine pipelines.

PORT OF DESTINATION:Vadinar is small coastal town located in Jamnagar district of the state of Gujarat, India. The offshore oil terminal of the Kandla Port Trust (K. P. T.) is located in Vadinar and contributes in a large way to the total earnings of this major port. Vadinar is now notable due to the presence of two refineries which are close by - one promoted by Reliance Industries and the other by Essar Oil Ltd. A salt production unit is located in Vadinar. The famous Narara Island, which is part of Marine National Park, is situated 7 kilometers away from town. You can also find the Jelly Fish, Star Fish, Crabs, Sea Turtle and many endangered species over there. Two single-buoy moorings (SBM) of the Kandla Port Trust offshore oil terminal of the Indian Oil Corporation are located at this port along with a similar buoy of the Essar refinery. The nearest airport is at Jamnagar 47 km away.

CARGO TO BE CARRIED:Heavy crude oil or extra heavy crude oil is any type of crude oil which does not flow easily. It is referred to as "heavy" because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°.[1]
Physical properties that differ between heavy crudes lighter grades include higher viscosity and specific gravity, as well as heavier molecular composition. Extra heavy oil is defined with a gravity of less than 10° API (i.e. with density greater than 1000 kg/m3 or, equivalently, a specific gravity greater than 1) and a reservoir viscosity of no more than 10,000 centipoises.[2][3] With a specific gravity of greater than 1, extra heavy crude is present as a dense non-aqueous phase liquid in ambient conditions.Heavy crude oil is closely related to natural bitumen from oil sands. Some petroleum geologists categorize bitumen from oil sands as extra heavy crude oil due to the density of less than 10 °API. Other classifications label this as bitumen differing it from extra-heavy oil. They differ in the degree by which they have been degraded from the original crude oil by bacteria and erosion. Often, bitumen is present as a solid and does not flow at ambient conditions.The largest reserves of heavy crude oil in the world are located north of the Orinoco river in Venezuela,[4] the same amount as the conventional oil reserves of Saudi Arabia,[5] but 30 or more countries are known to have reserves.Production, transportation, and refining of heavy crude oil present special challenges compared to light crude oil. Generally, a diluent is added at regular distances in pipeline carrying heavy crude to facilitate its flow.Heavy oil is asphaltic and contains asphaltenes and resins. It is "heavy" (dense and viscous) due to the high ratio of aromatics and naphthenes to paraffins (linear
4
alkanes) and high amounts of NSO's (nitrogen, sulfur, oxygen and heavy metals). Heavy oil has a higher percentage of compounds with over 60 carbon atoms and hence a high boiling point and molecular weight. For example, the viscosity of Venezuela's Orinoco extra-heavy crude oil lies in the range 1000–5000 cP (1–5 Pa·s), while Canadian extra-heavy crude has a viscosity in the range 5000–10,000 cP (5–10 Pa·s), about the same as molasses, and higher (up to 100,000 cP or 100 Pa·s for the most viscous commercially exploitable deposits).[1] A definition from the Chevron Phillips Chemical company is as follows:The "heaviness" of heavy oil is primarily the result of a relatively high proportion of a mixed bag of complex, high molecular weight, non-paraffinic compounds and a low proportion of volatile, low molecular weight compounds. Heavy oils typically contain very little paraffin and may or may not contain high levels of asphaltenes.[13]
There are two main types of heavy crude oil:1. Those that have over 1% sulfur (high sulfur crude oils), with aromatics and
asphaltenes, and these are mostly found in North America (Canada (Alberta, Saskatchewan), United States (California), Mexico), South America (Venezuela, Colombia and Ecuador) and the Middle East (Kuwait, Saudi Arabia).
2. Those that have less than 1% sulfur (low sulfur crude oils), with aromatics, naphthenes and resins, and these are mostly found in Western Africa (Chad), Central Africa (Angola) and East Africa (Madagascar).

An Aframax ship is an oil tanker smaller than 120,000 metric tonnes and with a breadth above 32.31 m.[1] The term is based on the Average Freight Rate Assessment tanker rate system. Due to their favorable size, Aframax tankers can serve most ports in the world. These vessels serve regions which do not have very large ports or offshore oil terminals to accommodate very large crude carriers and ultra large crude carriers. Aframax tankers are just perfect for short to medium haul crude oil transportation. Aframax class tankers are largely used in the basins of the Black Sea, the North Sea, the Caribbean Sea, the South and East China Seas, and the Mediterranean. Non-OPEC exporting countries may require the use of tankers because the harbors and canals through which these countries export their oil are too small to accommodate very-large crude carriers and ultra-large crude carriers.

BASIC SHIP APPROACH:The following lines plan of the new AFRAMAX has been generated by the use of the basic ship and the form parameter approach combined. We proceed in the following manner. 1. After finalizing the basic parameters (L,B,T,D,Disp.) we find out the length of entrance and run for the said ship using the empirical formulae. 2. Once the LOR, LOE are fixed we proceed to draw the sectional area curve using the trapezoidal method. 3. By an iterative process we arrive at a sectional area curve which matches with our desired disp. as well as its LCB matches the estimated value of LCB. 4. Than the stern and stem profiles are generated after considering all the clearances required to generate them and taking reference from the basic ship. 5. Then the draught waterline is generated after finding out the angle of entrance using the empirical formulae and matching the area with Awp calculated using the empirical formulas. 6. Now sections are drawn such that they match with the areas represented in the corresponding sections on the sectional area curve. 7. Once the body plan is completed we draw the half breadth plan by taking the offset from the body plan.
8. Using both of the previously generated plans we now generate the buttock plan of the ship. 9. The fairness of a ship’s hull is determined by the smoothness of its buttocks. 10. The rough un-faired offset table is thus obtained from the body plan. 11. These drawings can later be faired using softwares like Maxsurf etc. in which the offset is taken as the input. 12. The faired offset table and lines plan is thus generated.

BONJEAN CURVES:
In cases where vessels have unusually large appendages, it may be desirable to construct the curve of transverse section area with the inclusion of the shell thickness, corrected for the obliquity of the vessel's form, together with the cross sectional area of other appendages such as bilge keels. A longitudinal integration of such total cross section areas, together with the volume of appendages not intersected by the sections, would give the total displacement of the ship, but the calculation of the curves of cross sectional area would be too laborious for general use. The curves of cross sectional area for all body plan stations are collectively called Bonjean Curves. One of the principal uses of Bonjean Curves is determining volume of displacement of the ship at any level or trimmed waterline.
Bonjean Curves may be plotted in either of two ways. The curves for the ship are plotted against a common scale of draft, with the cross sectional areas for stations in the fore body and amidships plotted to the right of the vertical axis and those for the after body plotted to the left. The draft scale may represent keel drafts, or molded drafts, but the distance from the molded baseline to the bottom of keel should be shown. Such a presentation has the advantage of compactness, and uses one scale of cross sectional area. It is convenient to show a contracted profile of the ship adjoining the curves. An alternative plot is that in which a separate horizontal scale of cross sectional area is provided for each curve, and the curves are superposed on a contracted profile of the ship; in the latter case, the vertical axes coincide with the associated station lines in the profile. This arrangement is convenient for placing and locating trim lines on the profile, but has the disadvantage that the horizontal area scales for each station may be difficult to distinguish, one from the other, at areas of overlap. Draft scales corresponding to those on the ship should be shown at the appropriate locations on the profile.
A standard method of calculating volume of displacement and LCB is by integrating transverse sectional areas. If the waterline at which the ship is floating is not for the even keel condition, BonjeanCurves are particularly useful. In the case of a trimmed waterline, the trim line may be drawn on the profile of the ship and drafts read at which the Bonjean Curves are to be entered. By drawing a straight line across the contracted profile, the drafts at which the curves are to be read appear directly at each station. In as much as the curves of form are constructed for the ship in the even keel condition and most ships are not wall-sided, accurate hydrostatic characteristics for cases with a significant degree of trim are not in general obtainable from the curves of form and one must perform a complete longitudinal integration at the trimmed waterline (trim line) under consideration. The Bonjean Curves provide the basic input for such calculations.

THE GENERAL ARRANGEMENT PLAN:
Draw outline of profile, upper deck, forecastle deck. If upper deck is stepped show it that way. Forecastle deck should have a height more than 2.3m such that the required bow height as per ILLC rules is obtained (normally takes upto 3.0 m). Longitudinally, it should extend from forward end till the fore peak bulkhead or to the next bulkhead. The reason for a forecastle deck are:
1. Minimum bow height as per ILLC (reduction of probability of deck wetness) 2. Forecastle deck area for anchoring and mooring equipment 3. Adequate volume underneath for storage and chain locker etc. 4. Provide additional cargo space.
Divide the cargo space into holds by placing the remaining bulkheads. The principle of placing the bulkheads may be based on cargo requirement:
1. Equal length holds 2. Alternate large and small holds (bulk carriers/ products tankers/ container ship (as shown in the beginning ) 3. A single large hold (for large cargo in a multipurpose carrier)
Decide on longitudinal bulkheads - in double hull tankers, container ships etc. Discuss why in container ships – ballast requirement and box girder. Decide on sloped bulkheads on top and bottom wing tanks in a bulk carrier – top tank slope should be more than angle of repose of cargo – normally 300. Bottom tank slope is normally 450. Discuss why sloping bulkheads are provided in bulk carriers. The longitudinal and sloped bulkheads have a good relationship with cargo and ballast capacity; so this requires to be checked. Decide on double bottom height which should be more than centre girder height d as given below
(IRS): d = 250 +20 B + 50 T
Where d is in mm and B and T are in m.
The tank capacity below db should be adequate. Decide on height of tween deck(s). Ships carrying packaged cargo, such as multipurpose ships, non-standard cargo sizes such as refer cargo or some other cargoes such as cars etc., require large floor space. So, to provide more deck area, a number of tween decks are to be provided. The height of each tween deck should be adequate for the maximum height of cargo in that deck space. This is not required for volume based cargo such as tankers and bulk carriers. In container ships, the top of a container serves as the floor for the next higher container. So container ships do not require tween decks. Hatch openings and hatch covers.
Ballast Tank capacities and tank distribution. Ballast water is required for empty voyage to have proper sinkage, trim and stability. Excessive ballast capacity is bad since it is expensive and takes up useful space. Ballast capacity should be such that full propeller immersion is obtained at the aft end and forward draught is not too low to avoid the harmful effects of slamming. To avoid excess scantling IRS recommends a minimum forward draught of 0.04LBP (=TF). For , the ford scantlings are to be increased. For a TF < 0.025 LBP, direct calculations are to be submitted for approval. Approximately in a ballast voyage, displacement is 0.5 of fully loaded displacement which is about 0.55 of full draught. Ballast distribution should be such that excessive hogging moment is avoided in this condition. Segregate the B.W. tank from any other liquid tank.
The following points may be considered while making tank arrangements:
1. No access is required except for cleaning and maintenance. Minimum two manholes are to be provided on top preferably at diagonal corners.
2. Tanks and pipes carrying a particular type of liquid must be segregated from those carrying another type of liquid. 3. FW tank should not have any tank adjacent to itself. So an FW tank and any other tank must be separated by a cofferdam. For the
same reason, FW tanks cannot be placed below LWL. 4. Since total liquid carried relatively low, the tanks may conveniently be situated in the lower portions to increase transverse
stability. 5. To simplify piping arrangements FW tanks should be near E.R. as well as accommodation D.O. & H. F. O. tanks should be near the
E.R. for reducing piping length. D. O. can conveniently be stored in E.R. double bottom. B.W. tanks should be well distributed all over the length and breadth of ship to help stability and trim requirements. Pipes should not run inside tanks carrying another liquid, i.e. FO pipe should not run in B.W. tank. Consumable tanks (HFO, D.O. & F.W.) should be so located that their consumption does not cause unnecessary adverse trim. They should not cause unduly adverse free surface effects. So these tanks should be divided into smaller tanks with reduced breath. Too many small tanks, however, will make complicated piping system. B.W. tanks are either fully pressed or empty. B.W. tanks should be distributed all over the length of ship with sufficient capacity in the peak tanks to adjust for required trim and stability. Tanks should be distributed symmetrically about C. L. so that advice heel effects are not felt. If there is any such effect (damage stability) cross-connection between port and starboard tanks may be provided.
6. The boundaries of d.b. tanks, deep tanks etc. should be designed to withstand hydrostatic pressure. 7. The tank distribution should not adversely affect the longitudinal strength of hull girder.

SCANTLING &WEIGHT ESTIMATION CALCULATIONS:
Scantlings, steel weight, LCG & VCG of the bare hull were calculated for a 228 m long crude carrier. The scantling calculations for the above were done using the empirical formulae given in Part-3 of the IRS rule book.
LBP=228m, B=41.4m, T= 16.736m, D=21.6m (particulars of the crude carrier)
The weight calculations were done using the IRS class rules for :-
1. Shell plates – bottom. Inner bottom, side shell, main deck, superstructure tiers etc.
2. Bulkheads – Aft peak & Fore peak, transverse bulkheads, etc.
3. Girders – centre, side, deck girders.
4. Longitudinals – bottom stiffeners, side stiffeners, deck stiffeners, etc
5. Floor plates – solid floors, etc.
6. Frames – bottom, side, deck transverses, bulkhead frames, web frames, etc.
7. Brackets, stringers, Intercoastal girders, etc.
With the given GA, the approximate area of the shell plate was determined and multiplied with the thickness and density of steel to get the steel weight of the vessel.
The shell thickness formulae will have a design pressure term which is taken from different values obtained from various conditions and corresponding formulae. The largest of them is considered for calculation.
Number of frames is found from the GA where the frame numbers are marked. All the frames under the engine compartment and every fourth floor elsewhere are considered to be floor plates.
The stiffener weight is calculated using the chart which gives the weight per length of a particular stiffener type. The length of the stiffener is determined from the GA and multiplied with the wt./length to get the stiffener weight.
Weight of the brackets is considered to be about 10% of the stiffener weight.
The LCG is calculated by adding all the moments of the various shells, superstructures, frames, etc. about the aft and dividing it by steel weight.
The VCG is calculated by adding all the moments of the various shells, superstructures, frames, etc. about the keel and dividing it by steel weight.

PROPELLER
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law. A propeller is sometimes colloquially known as a screw.
PROCEDURE FOR PROPELLER CALCULATIONS:
Firstly, the propeller diameter is being taken from the calculations using all the propeller clearances.After that, the number of blades is fixed from the analysis done using the Hull Resonance DiagramThereafter the values of Wake Fraction and Thrust Deduction Factor are calculatedUsing the value of wake fraction, we calculate the velocity of advanceUsing the value of Thrust deduction fraction, we calculate the propeller thrustAs we know the value of Propeller RPM, Effective Power, Delivered Power we can calculate the value of Bp and δ.Thereafter various efficiencies such as Hull Efficiency, Relative rotative efficiency and Open water Efficiency are calculated by using empirical formulas. The values will be interpolated in the later course.Simultaneously, the blade area ratio will be calculated using the Keller formula, This will be the Selected Blade Area Ratio.We can select a propeller by using the number of blades and Blade area ratio, either from tables or empirical formulas. Hence you can select your propellerThereafter we have to look into the aspects of CavitationCavitation Number has to be calculated using the Difference between the vapour pressure and static pressure which are calculated from standard formulas and tables.Then we have to calculate the Developed Area, with the assumption that Developed area is equal to the Expanded areaUsing Bp-δ diagram we calculate the values of P/D ratio and Open water Efficiency, We can check the value of Open water efficiencyThe P/D ratio is input in the empirical formula in order to calculate the Blade Area Ratio; this BAR value will be taken as Calculated Blade Area Ratio.The Condition for Cavitation not to occur is that Calculated Blade area ratio should be less than Selected Blade Area RatioWe can check the risk of cavitation to our selected propeller.Hence Propeller calculations are completed.

Cavitation Account (Ae/Ao) = (1.3+0.3Z)T/(PO-PV)Dp2+K (K=0.2 single screw)
Bp= N*P0.5/VA2.5
δ = N*D/VA
Relative Rotative Efficiency= 0.9922-0.05908AE/AO+0.07424*(Cp-0.0225*lcb)
Hull Efficiency= (1-t)/ (1-w)
Delivered Efficiency= Effective Power/ Delivered Power
Open Water Efficiency= Delivered Efficiency/ (1-t)/(1-w)*Relative Rotative Efficiency
