why GLEN hook ensure quality

Cylindrical  Fenders  are commonly used fenders recommendedfor all type of applications to ensure a safeand linear berthing to a variety of vessels. Adequate installation is simply achieved by using chains, bars, ropes or peciallydesigned ladder brackets.

Foam Filled  Fenders  are versatile, robust and suitable for almost all applications. It uses high elastic foaming EVA as buffer medium,spira reinforcemrnt in the middle and Polyurea coating at outside. The EVA foam we use in the constraction of our Foam Filled Fenders is the closed cell type. It is made from Ethylene Vinyl Acetate and blended copolymers. It has a high level of chemical cross linking. These foams are flexible and esilientmaking them ideal for fendering products. Importantly, thefoams are also chemically inert and nonabsorbent making them suitable for use in marine nvironments. Features of Glen EVA Foam Filled Fenders: 1.Core material is closed and lyophobic. It is not bibulous even if damaged. 2.Polyurea protection layer can resist strong impact force and friction. 3.Can be customized in various colors.

Fender systems used for large vessel berthing are usually assembled with frontal panels to reduce the hull pressure, they are more complicated in structure than the traditional fenders for general purpose. The fender system will lose its protective function in case the structure was damaged. Therefore regular inspection is compulsory to be carried out for long-term operation safety. After the fender system is installed and put into service, inspection shall be carried out each time after berthing of the first three ships and then monthly inspections are to be conducted.  Inspection scope: 1 . Check the foot bolts for fender buffer installation and the bolts for fastening frontal panel. Fasten them enough in case of any loose and then fix the fastening bolt and washer by spot welding.   2. Check the fender buffer for any break or cut. Please contact our company immediately for any serious damage. 3. Check the frontal panel for any dent, crack or corrosion. If does, pl...

There are 3 types of chains in the fender system: tension chain, weight chain, and shear chain. The tension chain is to protect the fender from the damage while under local compression. The weight chain is to support the weight of front panel and the face panel. The shear chain is to protect the fender from damage while in shear deflection. The following items should be noted in chain design: The chain dimension should be as exact as possible, not too loose or too tight The chain can not be twisted as this reduces the load capacity Open link is preferred The initial angel of the chains is important. Normally weight chains are set at a static angle of 15~25 degree All the chains must be with safety factors which should be 2-3 times of the work load Shackle selection: the dimension of the shackle is usually the same as the dimension of the chain , but if the shackle is required to bear the same load with the chain, thicker shackle is preferred Selection and calculation...

The  face pad  is assembled with a flat pad and a corner pad as shown in the figure. Specifications Material Ultra high molecular weight polyethylene or Nylon resin are chosen as the material for face pads whose performances are shown in the following table. Physical Performance

How to design the front panel? The main function of front panel is to distribute the reaction forces from  fenders  units into the ship’s hull, so the design should be suit each individual berth. The loads and stress loads exert to front panel will depend on many factors- the type of ship, berthing mode, characteristic of the rubber fender and tidal range etc. The design of front panel should meet the following requirements: Resistance to bending moments and shear forces Resistance to impact on part There is no deflection on front panel and face pad during the compression Suitable corrosion protection for intended environment What’s the structure type of front panel? The front panel structure includes open style and closed style. The open style consists of steel pad, H steel and across steel. Closed style consists of steel pad, back steel and H steel. How to decide the dimension of the front panel? The following requirement should be considered in the design ...

Data Collection: Terminology In most cases, the actual  values  of the ship are used to calculate the effective berthing energy. Under some cases the actual values are not available, then the attached “Standard Sizes of Vessels” shall be referred to for calculation.

GLEN’s  rubber fenders  are manufactured from the highly quality nature rubber and other styrene butadiene SBR based compounds to satisfy various performance requirements. Other special rubber is also available upon customers’ special requirements. The main performance index is shown as below:
