Recently, many ship merchants have asked me about the berthing of ships.I think maybe these questions will help you.
Each dock has a series of products that will moor the boat.Usually this has two mooring methods.One is that the bollard is fixed on the pier and fixed through the connection of the mooring rope, so as to achieve the effect of mooring.Another type of mooring buoy, the buoy floats on the sea surface, and the anchor chain and anchor are connected below, thus playing a role in stabilizing the ship.Carrying out these two methods together will make the ship dock more stable.
If you lack a product in a certain link, or your current parking method is more novel. Welcome to communicate with me anytime!
Marine Rubber Airbag also known as rubber airbag, ship air bags, ship launching airbag, ship salvage airbag, boat salvage airbags, inflatable airbag, ship lifting bag, air balloon, made by rubber & multi layer of rubber-dipped tyre fabric.
Marine Rubber Airbag are widely used in launching and landing ship/ boat/vessel, lifting and moving heavy goods, salvaging stranded boats.
Marine Rubber Airbag are very popular with shipyard, ship owner, and marine supplies company now.
Marine Rubber Airbag has longer service life.
Whole Intertwine Technology
"HENGER" Airbags overall frame structure uses cross whole
intertwine technology, the overall structure is more reasonable,
texture clear, no juncture, high loads, more safety than lap
technology (roller), more than 20% bearing capacity.
“HENGER” airbag structure are consist of the outer rubber +
synthetic cord reinforced rubber layers.Its shape characteristics:
central body cylindrical + tapered on both ends. Cord layers:
4,5,6,7,8,9,10,11,12 layers.
The role of Marine rubber airbags
a. Marine upstream and downstream
b. Weight lifting & moving
Marine rubber fend could be applied to caisson lifting, launching, moving and transporting in port constructing projects.
c. Buoyancy Aid & Salvage
Because marine rubber airbag has buoyancy force and load-bearing capacity, it is also widely used in sunken vessel salvage and Buoyancy Aid.
4.Technical Requirement
According to CB/T 3795--1996, marine rubber fender should meet the following requirements.
1. Dimensional Deviation
Diameter & Effective Length Deviation: ±2%
Total Length Deviation: ±4%
2. Amount of Elastic Deformation: diameter deformation amount ≤ 5% under 1.2 times working pressure.
3. Safety Factor: >4.5
4. Air Tightness: depressurization < 5% after 1hour inflation
5. Surface Quality: fairing line shape, no crack, no bubble, no double skin, no impurities, no distinct dirt and other apparent defect.
6. end part anti-explosion design
5.Product Advantage
a. High bearing capacity
Inflatable rubber airbag’s main technical requirement is regulated in CB/T 3795--1996 published by China State Shipbuilding Corporation.
Henger adopts new rubber formula and high-strength enhanced synthetic-tyre-cord layer, which improves the airbag’s bearing capacity two times more than CB/T 3795--1996 standard
b. High kneading-resistance capability
When the airbag is rolling under the ship bottom, it will suffer a “kneading force” from ship bottom and ground because of not uniform rolling speed, which could case problems like delamination, layer buckling, etc.
Henger improved the manufacturing technique and raw material formula to strengthen kneading-resistance capability of the airbag and avoid worse accident .
c. New anti-explosion design of end part
The possibility of air leakage in the joint area of metal part and rubber part is also increasing as working pressure of airbag is added. After using for times under high working pressure, the airbag would burst and metal part would hurt workers.
Henger invented new anti-explosion design of the airbag end part, increasing the bonding strength and air tightness between rubber body part and end metal part. Henger airbag is working very well under higher working pressure without potential safety hazard.
d. Optimizing structure configuration
Henger built a strength and Intensity Model to test compression performance, stress intensity and direction. After testing for many times, we got the stress changeing regularity and optimized structure configuration design. The new optimized airbag successfully passed blasting experiment and achieved good performance in practical use.
e. Good Abrasion-resistance performance and high ageing resistance
The airbag is working under bad and poor condition, suffering from long time sunlight exposure, seawater corrosion, impurities pollution, etc. The surface of airbag must be equipped with high capability of abrasion resistance, ageing resistance, corrosion resistance.
Henger airbag is made of natural rubber with special ingredients and unique manufacturing method. The finished airbag could working very well under above mentioned bad and poor working condition.
f. Higher flexibility and shock absorption capability
Henger airbag is manufactured with unique integral twining technique. The airbag wall thickness is uniform with secondary seam in overlap joint. When rolling in slope and uneven ship path, the flexible airbag is helpful to reduce structure stress and ship launching risk.
