Natural rubber underwater air lift bags for shipyard

Product Introduction

Marine airbag is a new type of product developed independently in China which has been widely applied to ship upgrading and launching operation of ships, or help to float the stranded ships or to carry the heavy loads etc. Over more than 20 years of development, the marine airbag has become one of important choices for ship owners due its excellent performances and features including not limited by space, no need for large-size equipment, high efficient and simple

operation and smaller investment etc.

The marine airbag is manufactured and applied mainly with reference to two industrial standards.

Production Process

1. Ship launching and landing

Using airbag to launch or haul out a vessel is an innovative technology having utmost bright prospect in ship building industry. It has advantages of flexible, saving effort, time and labor, safe, reliable, and outstanding benefit, etc. The technology has been very mature in Asia and is widely used in US, RU, and other regions in the world. It overcomes the restrictions of traditional slide board technology which is commonly used in small and medium size ships. The vessel whose launching weight over 15,000ton with DTW over 55,000ton has been successfully launched by airbag technology.

2. Marine salvage

Marine salvage airbag is the best choice for 100-2000tons buoyancy need. Its good characters of easy transportation and store, little demand of maintenance make the salvage works more flexible and cost-effective.

Salvage marine airbags can be inserted between vessel bottom and seabed to lift sunk vessel which can partly restore buoyancy to vessel itself. Each salvage marine airbag can lift more than 200ton heavy under the water. For stranded vessel salvage this heavy lift function is extremely useful.

3. Heavy lift and transportation service

Besides used to launch and land a boat, marine airbag is also used to transport heavy objects on land and water, such as concrete building, bar dam, pipeline and cable laying and other water engineering projects. Still, airbag has the advantages of easy transporting, easy handling and cost saving.

4. Other Water Engineering Project Application, like pipeline laying,
