Sinomar marine fenders

The purpose of a marine fender system is to absorb the energy of a berthing ship. When considering the addition or replacement of marine fenders, it is important to consider all factors that make up the total energy package, including vessel weight (displacement tonnage), berthing velocity, angle of approach and dock design.  

 

Cylindrical fenders

Cylindrical fenders are commonly used fenders recommended for all types of application to ensure a safe and linear berthing for the different kind of vessels. Cylindrical (extruded) fenders are an economical solution to protect most of the berthing structures and offer much ease for installation.

Arch fenders

Arch fenders were introduced to improve upon the performance of Cylindrical fenders. Arch fenders are having a better Energy / Reaction force ratio and recommended for all types of applications. The very shape of these fenders helps to dissipate the stresses evenly. These extruded fenders are very easy to install and are maintenance free. Generally preferred for small to medium range Vessels.

Cell fenders

Cell fenders are best employed for smallest to biggest Vessels where Reaction Force is an important criteria. Among all types of fenders, Cell fenders offer minimum reaction per ton-meter energy absorbed. The very geometrical shape gives it sturdiness, shear resistance, compact Structure and the capacity to absorb energy equally from all directions. The Cylindrical buckling column absorbs axial loads effectively and buckles radially. This results in multi directional dispersion of energy. Cell fenders are the most durable rubber fenders available and are currently the largest moulded fenders made. ***0–***0 mm high cell fenders are typically used for LNG berths. In order to distribute the reaction force, cell fenders are typically supplied with large fender panels, which keeps the hull pressure low.

Cone fenders

Cone fenders are an improved version of Cell type Fender recently introduced and recommended for all type of applications including high tidal variation sites. This advanced feature of lesser height of fenders improves material handling capabilities of Deck / Vessel Cranes which reduces overall cost of the project. Due to the geometrical shape of the fenders it can deflect more and it can absorb more energy from any direction. Maintaining reaction force, but doubling energy absorption, can be achieved by using two identical cone fenders in a back-to-back arrangement. In order to distribute the reaction force, cone fenders are typically supplied with large fender panels, which keeps the hull pressure low.

Pneumatic fenders

These fenders are extensively used for ship to ship transfers at mid seas, double banking operation as well as vessel to berth at dock/jetties. The Special property of Pneumatic fender is its low reaction force at low Deflection. This very property of pneumatic fenders makes them most suitable fender for liquid cargo vessels and defence vessels with very sensitive equipments.These fenders offer excellent energy absorption characteristic and do have a linear Load Deflection Characteristic. Pneumatic fenders should comply to the ISO ****7 standard.

Foam elastomer fenders

These fenders are typically made of a closed-cell Polyethylene foam core, which is encapsulated in a nylon or Kevlar reinforced Polyurethane skin. The performance of foam elastomer fenders is comparable to that of a pneumatic fender, but the fenders will not lose their function in case the skin gets punctured. Foam elastomer fenders cannot deflate.

D fenders

D type fenders are commonly used on vessels as well as small jetties. They are compression moulded with steel inserts if required.

Square fenders

Square fenders are commonly used on vessels as well as small jetties. They are compression moulded fenders generally used on tugs, boats and ships.

Wing fenders

Wing fenders are compression moulded fenders and are generally used on tugs, boats and ships. Easy to install and replace. Do have excellent sea water resistance and resistance to ozone ageing and ultra violet rays.

Keyhole fenders

Keyhole fenders are the most versatile bow, stem fenders used on the Tugs Boats and small Port Crafts/Ferries. They offer maximum protection to the Tugs/Ferries with its typical profile and load absorbing capabilities.

Tug boat fenders

These fenders are made of high abrasion resistance rubber with good resilience properties for required application. They are very popular with small port craft owners and tug owners. These fenders are compression moulded in high pressure thermic fluid heated moulds and do have excellent sea water resistance.
