4 . INTRODUCTION INTRODUCTION COMPLIANCE WITH ISO7357:204 The "Yokohama Pneumatic Rubber Fender" was developed in 958 based on a rubber company's technology for automobile tires and rubber aircraft fuel tanks. Progress in the development of such floating pneumatic rubber fenders is closely related to the progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures. Floating pneumatic fenders are used world wide for shiptoship (STS) transfer operations, terminals, and for all kinds of ships. Since its creation until today, more than 60,000 fenders have been supplied worldwide both for shiptoship and shiptodock operations serving our valuable customers. These fenders play a critical role in the safe operation of ship berthing and mooring. 2. COMPLIANCE WITH ISO7357: 204 ISO7357:2002, the standard of high pressure of floating pneumatic rubber fenders, had been published in 2002 under growing needs for international standardization specified material, performance and dimensions of floating pneumatic fenders to prevent variety of originally designed products with low quality had been introduced into the market. In 204, ISO7357:2002 had been renewed as st edition of ISO7357:204 to strengthen its standard concerning design, material and certification of floating pneumatic fender. Although the structure is maintained from ISO7357: 2002 to ISO7357: 204 as shown in Fig, new requirements and new design listed below are added in ISO7357:204 aiming at higher berthing operation safe.

6 3. ADVANTAGES ADVANTAGES 3. Safety and Reliability Yokohama Pneumatic Rubber Fenders are constructed of several layers of strong tirecord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. Operational experience over a long period of time attests to its high safety and reliability, and hydraulic pressure tests have proven the strength to be suitable. Furthermore, largesize fenders are equipped with a safety valve to release the inside air in the event of accidental overpressure. The figure below shows data obtained from many destructive pressure tests at various percentage compressions. Such data are used to establish a basic minimum endurable pressure (MEP) curve for pneumatic rubber fenders. 7000L L 0000L 320L L 03000L L 2050L L Pressure (kpa) MEP ISO7357:204 MEP Deflection (3kPa) Yokohama's MEP Minimum Design Requirement Pneumatic MEP P60 ISO7357:204 MEP Deflection (5kPa) Deflection Fig.3 Burst Test Data to determine Minimum Design Requirements of MEP Fig.3.2 Burst Test at 0% Deflection Fig.3.3 Burst Test at 60% Deflection YOKOHAMA PNEUMATIC FLOATING FENDERS & 3

7 3.2 No Deterioration or Variation in Performance Yokohama Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore performance deterioration due to fatigue is absent. In the case of solid rubber fenders or foamfilled fenders, based on data were taken from comparison tests of Yokohama Fenders, there are variations in performance. Such performance variations are associated to changes of rubber or foam hardness occurring as a result of cyclic compression and temperature change. 20 ADVANTAGES Relative Reaction Force Pneumatic Solid Cell Foam Relative Reaction Force Pneumatic 60 Solid Cell Number of Compression Cycles Temparature Fig.34 Variation in Performance on Cyclic Compression and Temperature In the case of Yokohama Pneumatic Rubber Fenders, if the pressure is maintained properly, such variations are absent. Yokohama Pneumatic Rubber Fenders also fully comply with the durability test required by ISO7357:204. After 3000 repetitive cycles, there must be no cracks or other harmful defects on any part of the fender. Any reduction of the guaranteed energy absorption (GEA) is not accepted. Table 3 Cyclic Compression Results for Yokohama Pneumatic Rubber Fenders Items original After 3000cycles GEA (index) Reaction force at GEA (index).04 Deflection at GEA (%) The good performance of the Yokohama Pneumatic Rubber Fenders remains unchanged even at temperatures under degrees Centigrade (58 degrees Fahrenheit). 4 YOKOHAMA PNEUMATIC FLOATING FENDERS &

8 ADVANTAGES 3.3 Advantages at Inclined Berthing Ships usually make initial contact with the dock or another ship on STS operations at an oblique angle. In the case of solid rubber fenders or foam fenders, rated reaction force and energy absorption decreases considerably at inclined compressions compared with parallel compression. In order to compensate for the decrease of energy absorption at inclined compression, it is necessary to use larger sizes in the case of solid rubber fenders or foam fenders. Percentage of Max. Energy Absorption Compression Percentage of Max. Rated Energy Absorption Compression Percentage of Max. Rated Energy Absorption Compression (a) Pneumatic Fender (b) Solid Fender (c) Foam Fender Fig.35 Reduction of Energy Absorption at Inclined Berthing for Pneumatic, Solid and Foam Fender In the case of Yokohama Pneumatic Rubber Fenders, energy absorption does not decrease at inclined compression up to 5 degrees. Fig.36 Load Distribution at Inclined Berthing for Pneumatic, Solid and Foam Fender Distribution of load is also comparatively even because of the molecular freedom of air and high flexibility of the multilayered cordreinforced rubber membrane. This makes the body of a pneumatic rubber fender more shape conformant compared to solid or foam fenders, and thus able to better distribute the load along the hull of a ship or jetty structure during inclined compression. YOKOHAMA PNEUMATIC FLOATING FENDERS & 5

9 3.4 Most Cost Competitive System The utilization of the compressive elasticity of air, unlike other fenders which need protector panels, provides completely uniform surface pressure on contact, making Yokohama Pneumatic Rubber Fenders ideal. The surface pressure of the Yokohama Pneumatic Rubber Fenders is equal to the internal air pressure. The pressure of some is below kn/m 2 (5 ton/m 2 ). Due to low and uniform surface pressure properties, the Yokohama Pneumatic Rubber Fenders are popular at LNGship terminals.

10 ADVANTAGES 3.5 Soft Reaction Force for Ship and Jetty Structure Although all fenders should be used within their maximum load limit, it often happens that fenders accidentally receive excess load. The reaction force of Yokohama Pneumatic Rubber Fenders does not increase sharply, even under excess load conditions. Therefore, the Yokohama Pneumatic Rubber Fenders perform well in such cases, and protect ships and mooring facilities. In contrast, the reaction force of solid rubber fenders, including bucklingtype fenders, increases sharply under excess load conditions. The excess load turns the solidtype fender into a solid rubber block, which cannot perform as a fender. This often leads to damage of the ship and mooring facilities. Solid fenders Yokohama Pneumatic RubberFenders Reaction force A B C D A' B' C' D' Compression stages A, A' : First buckling point of solid fender. B, B' : Normal deflection point during typical berthing. C,C' : Designed rated energy point. D, D' : Abnormal berthing Deflection Fig.39 Soft Reaction Force for Ship and Jetty Structure Fig.39 above compares the reaction force generated by a typical solid rubber fender to a pneumatic rubber fender at different compression stages during a typical berthing operation. The curves are derived from the performance of a solid rubber fender and a pneumatic rubber fender with the same energy absorption performance. Points A', B', C', and D' along the reaction curve for the pneumatic fender represent matching energy absorption performance at point A, B, C, and D on the reaction curve for the solid rubber fender. The table below compares the typical reaction loads and hull pressure imposed by solid and pneumatic type fenders at various compression stages, and it can be seen that the Yokohama Pneumatic Rubber Fenders are ideal as fender system because of gentle treatment of ships. Compression Stage A, A' : Buckling point of solid fender B, B' : Normal deflection point C, C' : Designed rated energy point D, D' : Abnormal berthing point Comparison Pneumatic fender has lower reaction force and exerts lower hull pressure compared to the solid rubber fender Pneumatic fender has lower reaction force and exerts lower hull pressure compared to the solid rubber fender Pneumatic fender has slightly higher reaction force only at this point Pneumatic fender has lower reaction force and exerts lower hull pressure compared to the solid rubber fender YOKOHAMA PNEUMATIC FLOATING FENDERS & 7

11 3.6 Lower Mooring Forces under Rough Weather Conditions During mooring under rough weather conditions such as high waves and strong wind, large ship motions are induced by high waves, long period waves or a resonant effect between the natural period of a ship and the predominant period of the waves. This movement results in compression and shearing forces on fenders. The reaction force and deflection of solidtype fenders under rough weather conditions easily reaches their respective maximums. Therefore, repeated compression with shearing force resulting from the movement of ships causes fatigue and often damages solidtype fenders. On the other hand, the reaction force and deflection of Yokohama Pneumatic Rubber Fenders do not easily reach the maximum because the reaction force increases slowly and allowable deflection is wide. Thus, the Yokohama Pneumatic Rubber Fenders safely protect ships and mooring facilities even under rough weather conditions. The use of Pneumatic Rubber Fenders sometimes eliminates the necessity of constructing a breakwater in the harbor. There are many studies and reports relating to the above subjects. 34m Z G 0 7m 8.3m 4m X +2 m m 0 2 SWAY SWAY (a) Pneumatic (b) Solid (Buckling) 000 sec 000 sec ADVANTAGES Fig.30 Model Studies on Ship's Movement with Yokohama Pneumatic Rubber Fender & with Buckling Fender Fig.3 Calculation Results of Harbor Oscillations for Ship Motions moored along Quay Walls 8 YOKOHAMA PNEUMATIC FLOATING FENDERS &

12 ADVANTAGES 3.7 Stronger against Shearing Force After contacting a dock, a ship is usually shifted to the correct mooring position. The shifting exerts shearing and compression forces on the fenders. This combined force is very severe in the case of solid rubber fenders because they are not reinforced against such force. In contrast, Yokohama Pneumatic Rubber Fenders are adequately reinforced using strong tirecord to cope against such forces as well as internal pressure. Berthing Force Shearing Force Fig.32 Stronger against Shearing Force 3.8 Adaptable to the Tide Yokohama Pneumatic Rubber Fenders basically float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement. This means that energy absorption always takes place at the most suitable position, and that only one fender is required per dolphin. H.W.L. dolphin L.W.L. Fig.33 Adaptable to Tide YOKOHAMA PNEUMATIC FLOATING FENDERS & 9

13 3.9 Simple and Low Cost Installation The weight of Yokohama Pneumatic Rubber Fenders is supported by the water on which it floats. Therefore, the fender can be moored simply by means of a guy rope or chain, requiring minimal extra cost. It can be removed easily to a suitable jetty or quay when not in use, or transferred to another mooring point whenever required. ADVANTAGES Fig LP Yokohama Pneumatic Rubber Fenders installed at a dolphin 3.0 Low Maintenance Cost Maintenance cost is very low. Although the internal pressure will vary with seasonal changes, the air leakage is so minimal that it is sufficient to check the air pressure only once a year. The chain net needs to be replaced only once in 3 or 4 years, depending on ambient conditions. 3. Shipping Cost Minimization In order to minimize the shipping cost of Yokohama Pneumatic Rubber Fenders, the fenders are usually packed and shipped in containers or on pallets in vacuumed and folded down state.

19 4.4.3 Fender Monitoring System ( FMS) Fender Monitoring System has been developed to monitor offshore ShipToShip (STS) operation. The system incorporates technology from the design of pneumatic fenders and the numerical simulation analysis of dynamic ship motion. The system can simultaneously monitor the state of pneumatic fenders used as shock absorber between the two ships and the behavior of both ships. This wireless fendermonitoring system can be also applied to onshore ShiptoDock operation anywhere in the world. PRESSURE RATING, TYPES AND VARIATIONS LowPressure (LP) The LowPressure fender type is a pneumatic fender designed with a lighter body construction. It is popular for application requiring large clearance between the ship and jetty or between two ships but not necessarily needing the high performance of a standard highpressure pneumatic fender.

20 4.4.5 LightWeight LightWeight fenders are focused on portability, and are small and light for convenient use with cruise ships, pleasure boats, and other small boats. PRESSURE RATING, TYPES AND VARIATIONS Vertical VerticalPneumatic Rubber fenders are specially designed pneumatic fenders that can be waterballasted and installed vertically. They are popular with vessels whose berthing point is below the water line such as catamaran ships, semisubmersibles platforms or other submersibles Globuoy Globuoy is a modified pneumatic fender for use as a surface or subsea buoy in equipment installation, mooring, anchoring and various offshore operations. It can be used with higher working pressure or can be filled with pressure resistant material for various under water applications. The pneumatic design of the Globuoy makes it easy to handle and launch due to its light weight. Also, because of the flexible reinforced rubber body, it is less prone to damaging or being damaged by the decks or hulls of vessels. It is a noncollapsible buoy in case of oversubmergence.

22 5. BASIC CONSTRUCTION The Floatingtype Yokohama Pneumatic Rubber Fenders are kind of a cylindrical air bag with hemispherical heads at both ends. Basic body construction of this fender consists of an outer rubber layer, cord layers and an inner rubber layer. All of these are vulcanized together, and then proven by hydraulic pressure test. 5. Outer Rubber The outer rubber layer protects the cord layers and inner rubber layer from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage as shown in Table 5. Standard color is black, but other colors such as grey and creamy white are available on request. BASIC CONSTRUCTION 5.2 Synthetictirecord Layer The reinforcement cord layers, which are made of Synthetictirecord, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly. As the main fibers of the synthetictirecord are not braided like synthetic canvas fabric or synthetic belt fabric as shown in Fig.52, there are advantages for its fatigueresistance performance and pressureholding performance. 5.3 Inner Rubber The inner rubber layer seals the air inside, utilizing a compound equivalent to that of the liner or tube of an automobile tire. The specifications are shown in Table 5.

24 5.4 Bead Ring and Flange Opening 5.4. Bead Ring A steel ring is placed at one or both ends of the fender to hold the end of the reinforcement cord layers. The outside diameter of the bead ring has been designed smaller than 20% of the fender diameter to maintain the fender's safe compression up to %. BASIC CONSTRUCTION Flange Opening A steel flange to which air valves are attached is mounted on the fender to serve as flange opening. The flange opening is designed smaller than 2% of the fender diameter to maintain safe compression up to % compression.

25 5.5 Turnup System The reinforcement cord layers are turned upward around a bead, which is builtin near the flange opening, except for small sized fenders. This system was originally invented for automobile tires and is quite reliable for distributing loads evenly without any concentration of stress on cord layers. 5.6 Air Valve and Safety Valve Medium and small sized Floatingtype Yokohama Pneumatic Rubber Fenders are equipped with a small air valve, which is the same in size and construction as the air valve of an automobile tire. This valve serves as both aircheck, air charge and release valve. On the large size fenders, the small air valve, a globe valve and a safety valve are equipped, the small valve serves for an aircheck, the globe valve having a one touch joint coupler serves for air charge and release, and the safety valve serves for releasing excess internal pressure when the fender is accidentally over compressed.

32 6.3 Safety Design and Pressure Requirements 6.3. Overcompression The guaranteed energy absorption of Yokohama Pneumatic Rubber Fenders is the energy absorption at 60% deflection. This figure should be observed in engineering design and in actual operation. However, even if the fender is accidentally overdeflected beyond this guaranteed value, the Yokohama Pneumatic Rubber Fender has a wide safety margin as shown in Fig.64 and Table 65 below. These curves and table express the capacity for energy absorption and reaction force until the time of ultimate deflection when the deflection of fender reach the largest diameter of mouthpiece metal parts.

34 The minimum endurable pressures at 0% compression and 60% compression are the most important parameter in the design of a pneumatic fender. Therefore, more than twenty prototype fenders have been burst to establish the design standard to keep this pressure strength for all Yokohama Pneumatic Rubber Fenders.

35 6.4 Fender Compression Speed Performance requirements of reaction force and energy absorption for Yokohama Pneumatic Rubber Fenders are basically evaluated for static conditions with a constant slow compression speed of 0.00m/s. However, during actual ship berthing operations, the Yokohama Pneumatic Rubber Fenders are dynamically compressed at speeds over 0.05m/s. The Fig.66 below shows the effect of compression speed at 60% deflection against the static rated values on reaction force and energy absorption. The reaction force and energy absorption increase together with compression rate. In actual ship berthing conditions those values are about 20% higher compared to those of static compression.

Therefore, the performance of the fenders is stable relative to temperature variations when the initial internal pressure is set to be the specified pressure. 32 YOKOHAMA PNEUMATIC FLOATING FENDERS &

36 7. FENDER SELECTION 7. ShiptoShip The fender selection procedure for shiptoship operations is outlined below. Two ship types, sizes and weather conditions such as Calm, Moderate and Rough are initially confirmed. 7.. OCIMF Table Selection Equivalent displacement coefficient ; ''C'' is calculated, and fenders are selected tentatively by using the table in OCIMF ShiptoShip Transfer Guide ; ''OCIMF Table Selection'', Table 7. In this case, initial internal pressure of the fender shall be kpa (Pneumatic ). The selections are designed based on Calm weather condition, therefore if the weather is confirmed as Calm, the fender system can be simply selected from the tables.

37 7..2 Berthing Energy Selection Berthing energy of the two ships is then calculated ; "Berthing Energy Selection". If energy absorption capacity of the tentative selected fender (Ef) is larger than the calculated berthing energy (E), it is confirmed that a suitable fender selection has been made. If the fender energy absorption capacity is less than the calculated berthing energy, the tentatively selected fender shall be upgraded Fender Selection procedure Fender selection procedure for shiptoship operations is illustrated below.

38 It is obvious from Fig.72 below that ship s displacement at the ordinary lightering or the reverse lightering operation is smaller compared to that for the fullfull berthing, however, at the severest condition when the two vessels are both almost full, the displacement become similar to condition of the fullfull berthing and therefore the fender system should be selected considering the fullfull berthing even in case of the ordinary lightering and the reverse lightering operation.

39 7..5 Berthing Energy The berthing energy needs to be calculated considering weather conditions, categorized by the three conditions Calm, Moderate and Rough, and the approaching velocities to calculate the berthing energy are assumed to be as shown in Table 73 and Fig.73. These are obtained from various industry references and standards. The three different weather conditions are defined by sea state and significant wave height as shown in Table 73. This table shows figures for tankers, but it can be applied to other kinds of ships, if their virtual weights correspond to those in the table.

40 7..6 Safety factor A safety factor (SF) value from.0 to 2.0 for the berthing energy shall be considered for abnormal berthing conditions Fender upgrade When the fenders need to be upgraded, increasing the fender diameter is preferable. Increasing the length or initial internal pressure from pressure kpa to kpa is not recommended. If the length or internal pressure is increased, the reaction force and energy absorption are increased. However, the gradient of the curves become steeper without providing any significant increase in allowable compression capacity as shown in Fig.74. On the other hand, in the case of using a larger diameter fender keeping the pressure kpa, the performance curves of the fenders have almost the same gradient, and the allowable compression capacity is increased. Therefore the larger diameter fender is preferable to keep safe standoff distance between two ships during berthing and mooring R (kn) P R (kn) P P FENDER SELECTION Reaction Force (kn) 00 R (kn) P R (kn) P C P B P A P Compression ( m ) Option Increase Diameter Increase Pressure Increase Length Curve Gradient A B C Effectiveness Best Acceptable Not Recommendable Fig.74 Fender Performances relating to Size in Length and Diameter, and Initial Internal Pressure 7..8 Fender Selection Tables Tables 7.4 through 7.9 show the fender selection tables for various kinds of tankers coming alongside lightering ships at three weather conditions; Calm, Moderate and Rough, for each ship size. In the tables, the berthing energy, equivalent displacement coefficient and suitable fender system for each case are indicated. This table shows figures for tankers, but it can be applied to other kinds of ships if their virtual weights correspond to those in the table. In the tables, a safety factor SF=.0 is used, but if a higher SF value is to be considered, the energy value is to be multiplied by the desired SF value and the fender selected according to the revised energy value.

47 7..9 Fender Selection by Numerical Simulation for Two Ships Berthing and Mooring Fender quantity and size will be determined by calculating the berthing energy, derived from the calculated virtual mass and the relative berthing speed between the two ships. In some cases large ship motions are induced by waves, wind and current. Consequently, excess loads are given to the fenders. In severe weather conditions, fenders used for ship berthing or ship mooring need to be selected after a more thorough investigation of the ship's motions under dynamic conditions. Furthermore, when two ships are moored together during STS operations, not only the fenders but also the system of mooring lines needs to be studied as it has the important role of keeping a proper standoff distance between the two ships. The Yokohama Rubber Co., Ltd. developed the numerical simulation software IAMOS (Integrated Approach, Mooring and Operation Simulation for Ship/FPSO to Ship Operation), and will provide the analysis for customers on special request. Fig.75 through 78 show details of the IAMOS process.

49 7.2 ShiptoJetty The selection of a pneumatic fender system (sizes and installation methods) for a jetty is determined based on several design parameters for each ship berthing and mooring condition Fender Selection for Berthing and Mooring of Ships Ship size and condition, as well as berthing velocity are at first determined. Then berthing energy "E" is calculated, and a fender is selected based on the berthing energy requirement. A safety factor (SF) value from.0 to 2.0 for the berthing energy shall be considered for abnormal berthing conditions. Fender selection procedure for shiptojetty operations is illustrated as Fig.79 below. E : Ship berthing energy (knm) W : Displacement (ton) V : Berthing velocity (m/s) d : draft (m) B : Breadth (m) Ce : Eccentricity factor Cm : Virtual mass factor, Cs : Softness coefficient Cc : Berth configuration factor SF : Safety factor Fender Selection FENDER SELECTION Ship Types, Ship Sizes and Conditions Berthing Velocity (V) based on Weather Condition (Calm, Moderate, or Rough) Berthing Ship Berthing Energy ; Max.

50 7.2.2 Berthing Energy Tables Tables 7 through 77 show the berthing energy for various kinds of ships and sizes at different approaching speeds corresponding to Calm, Moderate and Rough weather conditions as shown in Table 70. In the tables, a safety factor SF=.0 is used, and if a higher SF value is to be considered, the energy value is to be multiplied by the desired SF. Table 70 shows figures for tankers, but it can be applied to other kinds of ships, if their virtual weights correspond to those in the table.

54 7.2.3 Fender Selection by Numerical Simulation for Ship Motions Moored along Jetty Fender quantity and size will be determined by calculating the berthing energy, derived from the calculated virtual mass and berthing speed. During mooring of a ship, large ship motions are induced by waves, especially longperiod waves and harbor oscillations, and in some cases breaking accident of mooring lines or fenders occur. In order to check for a suitable fender and mooring system under severe weather conditions, a computer simulation for evaluating ship motions and mooring loads on fenders and mooring lines under dynamic condition should be conducted. The YOKOHAMA RUBBER CO., LTD. developed the numerical simulation software IMOS (Integrated Mooring and Operation Simulation for Ship to Jetty Operation) and will provide the analysis for customers on special request. Fig.70 through 74 show details of the IMOS.

Installation examples Four largesize fenders are usually floated at the water line as primary fenders to absorb impact energy at berthing and keep proper standoff distance between two ships. Two smallsize fenders (secondary fenders) are hung high on the hull at both bow and stern of smaller ship to prevent contact from rolling of ships due to swell and wind. "STS Transfer Guide", published by CDI, ICS, OCIMF, SIGTTO, is a good reference for further information.

71 . PRECAUTIONS ON HANDLING () Because the pneumatic rubber fender is usually shipped in deflated condition (as shown in the pictures below), it should be immediately inflated to the pressure 20 30kPa upon arrival at its destination. (2) When storing the fender more than three months without use, reduce internal pressure to about half of initial pressure (2030kPa) so that the pressure will not rise too high due to a rise in the atmospheric temperature. Do not deflate or fold.
