JSC400H~JSC3000H Super Cell Fenders

0 Comment

Conventionally, rubber fender materials have been selected with priority given to whether or not they have sufficient ability to absorb the energy coming from a mooring ship. With progressing competition among harbor operators, however, there has been a growing tendency to place more priority over the cause no damage to the hull structure. In particular,.. read more →

Rubber Fender Units

0 Comment

If correctly selected and positioned, the rubber fender unit(s) will absorb the kinetic energy of the largest, intermediate and smallest ships to use the berth. The rubber units need to cope with different compression speeds, high and low temperatures, berthing and bow flare angles, and occasional or frequent use. They may need to resist shear.. read more →

Marine Fender Type and Style

0 Comment

Many vessel to vessel operations use large marine fenders like foam filled fenders or pneumatic fenders. The marine fenders used in vessel to vessel transfer operations offshore are divided into two categories. Primary marine fenders which are positioned along the parallel body of the vessel to afford the maximum possible protection while alongside, and secondary.. read more →

Fender system for the large vessel

0 Comment

Fender systems should be determined considering not only the absorption of the external load by the vessels berthing and mooring, but also the hull pressure of the vessel and the reaction load to the structure to ensure protection of them both. It is general for piled dolphins with vertical piles that the energy absorption by.. read more →

Fender Support Systems

0 Comment

The three fender support systems, those of pile and frame, chain suspension and unit support, need to take into account the requirement for a fender system to remain operative even though damage may have been sustained by an exceptional impact. It is preferable to have units which are easily removed before the next berthing takes.. read more →

Fenders as part of mooring system

0 Comment

Fenders as part of mooring system Vessel motion shall be considered against winds and waves, swells, and long period waves entering from the ocean. Especially, in the design of mooring systems of offshore deep water terminals, forces due to vessel motions are also important items to be considered as well as vessel berthing forces. As.. read more →

Workboat & Tugboat Fenders

0 Comment

The rubber fender for a workboat or a tugboat must not only absorb the berthing energy but also must resist the strong pushing pressure exerted by the ship after berthing. In addition, it must minimize any possible damage to both the work boat and the ship while redistributing the pushing force to the ship with.. read more →

Our super arch fenders offer improved efficiency and angular performance, whilst the new anchor layout pattern give better stability and a stronger attachment to the supporting structure even under very heavy impacts. All Arch Fenders share the same single piece construction with encapsulated steel mounting plate vulcanized into the base flanges. As a wharf protection.. read more →

Rubber Fender Systems for marine structures are generally designed according to the following procedure: Berthing energy is calculated by the following kinetic equation Ef= Wa/2g • V2• Cm • Ce • Cc • Cs (4.1 ) Where Ef: Berthing energy (tf•m) g: Acceleration gravity (9 8m/sec2) Wa: Water displacement of the berthing ship (tf) V:.. read more →

The type of rubber fenders that is most suitable for an application depends on many variables, including dimensions and displacement of the vessel, maximum allowable stand-off, berthing structure, tidal variations and other berth-specific conditions. The size of the fender unit is based on the berthing energy of the vessel which is related to the square.. read more →
