Disembarking Ships Marine Rubber Airbag For Salvage Lift

Disembarking Ships Marine Rubber Airbag For Salvage Lift

Introduction

Marine rubber airbags have revolutionized the way ships are disembarked and salvage operations are carried out. These versatile and powerful tools offer a cost - effective and efficient solution for a variety of marine tasks. In this article, we will explore the use of marine rubber airbags specifically for ship disembarkation and salvage lift operations.
Marine airbags are found to be powerful and versatile tools for many other marine projects such as disembarking ships, heavy transportation, re-floating salvage etc. But how to select suitable marine airbags for a specific project? Let us see suggestions from a professional marine airbags manufacturer and engineering company.

How Marine Rubber Airbags Work in Ship Disembarkation

Principle of Buoyancy
Marine rubber airbags operate on the principle of buoyancy. When inflated, they displace a significant volume of water, creating an upward force that can support the weight of a ship. This buoyant force allows the ship to be lifted off the ground or a docking structure, facilitating its movement during disembarkation.
Placement and Inflation
During ship disembarkation, the airbags are carefully placed beneath the ship's hull at strategic locations. The number and placement of the airbags depend on the size, shape, and weight distribution of the ship. Once in position, the airbags are inflated using specialized air - filling equipment. As the airbags inflate, they gradually lift the ship, reducing the friction between the ship and the surface it is resting on.
Controlled Movement
The inflation and deflation of the airbags can be precisely controlled. This allows for a smooth and gradual disembarkation process. By adjusting the pressure in the airbags on different sides of the ship, operators can also control the ship's orientation and movement, ensuring a safe and accurate disembarkation.

Reference for marine airbag selection

There are two industrial standards for marine airbags in China.: one is product standard named "Air bag for ship up to or down to launching way "; another is technology standard named "Technological Requirements for ship Upgrading or Launching Relying on Air-bags"



The latter provides basic calculations for marine airbags in marine projects.
Based on Chinese industrial standards, people can estimate the approximate quantity and specifications of marine airbags for their projects and then consult the manufacturer to finalize the design. For a specific project, there may be optional specifications, and a good manufacturer should be able to suggest the best option. The blasting pressure data of marine airbags reflects product quality. For example, a top - quality 1.5 - m - diameter and 7 - m - long Evergreen marine airbag has a blasting pressure of 0.67 Mpa, with a safety coefficient of over 5 considering its 0.12 Mpa working pressure.
A good company should offer full technical services. While most factories can provide general calculation formulas and performance data, detailed calculations based on mathematical models and experience are crucial for marine project success.
In short, choosing the right marine airbags is essential for marine project success. Learning basic selection knowledge and consulting manufacturers can help complete projects quickly.

Initially established as Qingdao Luhang Marine Airbag Factory in 1988 and changed to Qingdao Luhang Marine Airbags and Fenders Co.,Ltd in 2011, Qingdao Luhang had been devoted itself to developing and manufacturing marine airbags and marine fenders for more than 2 decades.

The factory area is 56,000m² with building area of 21,000m². The company has registered capital of USD 3 million and fixed asset of USD1.2 billion. We have a full line of production equipment: rubber mixing machine, rubber roller machine, the China biggest vulcanization tanks, the biggest Press Inspection Machine, EVA foam processing machine, Foam shaping machines and SPUA spraying machine.

Through these years' development, we have full range of marine airbags and marine fenders:

Ship Launching Airbags for ship launching and docking in shipyards

Marine Salvage Airbags for salvaging sinked vessels or refloating objects from under water

Other Airbags for special usage

Pneumatic Rubber Marine Fenders for ships and docks berthing

Foam Filled Marine Fenders for ship and docks berthing

Fixed Dock Rubber Fenders for docks and wharfs

Marine Buoys

From the begginning we have been focusing on technological innovation. With a team of experienced technicans and engineers, we have developed some high tech marine products and got some petents. We have been approved as a supplier of Navy products.

Quality is our life line. We provide service of “three guarantees” (returning, repairing and replacing) on all our products in case of any defects due to the problems of material,manufacturing, performance under conditions of normal operation and maintenance.
