NANHAI MARINE AIRBAG FOR SHIP LAUCHING

NanHai offers total pack for launch and haul-out projects which include launch design, airbags supply,  on site support and worker training also we can provide launch or haul out service according to demand. After years of practice and accumulation of experience, we have developed this ship launching techniques from facilitating the launching of only 1,000 DWT ships to current 60,000 DWT ships. And now this launching technology has become into a flexible, promising, secure and mature technology. Besides that, NanHai - marine airbags are widely used in launching and haul-out of vessels of all sizes.

Besides the airbags, we can design suitable solution for your projects and provide any equipments that are need druring the salvage, including rope or rope net,  winch, rubber tube and air compression machine, etc.

CONSTRUCTION OF THE NANHAI - MARINE RUBBER AIRBAG

NanHai - marine rubbr airbags, basic body consists of which consist of our rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll.

Normally when we say the length of the airbag, we mean the Effective Length

1). Outer Rubber
The outer rubber layer that covers the outside of launching airbags protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black.

2). Synthetic-tyre-cord layer for reinforcement
The reinforcement cord layers, which are made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
(To know the detailed technology parameter, please refer Material Selection. )

3). End Fittings
End fittings include air tightness swivel and airbags safety air inlet.

NanHai-Marine Airbag is to be constructed of an outer rubber layer, one or more Synthetic-Tyre-Cord layers, and an inner rubber layer.
The arrangement of Synthetic-Tyre-Cord reinforcement layers is showed below. All materials shall be vulcanized firmly.

MAJOR STRENGTHS OF NANHAI-MARINE AIRBAG

NanHai-Pneumatic Fender can totally meet the ISO 14409 standard

1. More safety: Nylon-6 Dipped Cord fabric, 3chords, single strength>313N, 1.5times than commons

2. More unique design: S316 Stainless steel designed airbag head, avoiding the irreparable damage at the ends; The drag end could stand the whole weight of the airbag, and it is very convenient to be dragged by a crane

3. More longer lifetime: 100% natural rubber, the lifetimes is at least 2 or 3 times than commons

4. Better air tightness: Guarantee 72 hours(3days) no air leakage

5. Different airbag size stock available, quick delivery

6. No harm to the environment, Time & money saving

7. Wear resistance and anti aging, Long time service life can be reused many times

APPLICATION OF NANHAI-MARINE AIRBAG

1. For ship upgrading, conversion or new/repair launching

2. Marine airbag for salvaging sunken ship or heavy immersed steel structure
