Marine Airbags
Marine Airbags and Launching Airbags
Ship Launching, Haulouts, & Salvage
ISO 14409
Ship Launching Airbags. Also known as inflatable marine airbags, roller bags, air lift bags, and salvage bags. Airbags range in size from 0.8 to 2.5m diameter, with lengths of 5.0m to 24.0m ‘effective length’. Airbags are used for ship launching, haul-outs, loading, and floating. They are widely used in cargo boat launching and landing, lifting and moving sunken ships, and salvaging stranded boats. Air bags have the benefit of not only saving labor and time, but investment costs. Additionally they are flexible, portable, and dependable.
LAUNCH UP TO 55,000 DWT!

Ship Launching Airbags relieve the restrictions of traditional slide-board technology which is commonly used in building small or medium size ships, and it provides an economical alternative to expensive dry docks.
Air bags also allow for the landing of vessels in locations previously restricted only to dry docks. Years of trial and error with pneumatic roller bag technology has increased the ability of launching 100-ton ships to 13,500-ton ships!

6-layer bags that are 1.5m dia x 15m long for example contain a rubber content that is not less than 51%. The air-bags can safely hold 234-tons with a safe working pressure of 0.12MPa while rolling. When standing still the highest lifting pressure is 0.14MPa while holding 272-tons.
LONGEST EFFECTIVE FLAT LENGTH IS 24.0 METERS

SALVAGE AIRBAGS SHIPWRECKS AND SUNKEN STRUCTURES
In order to meet the requirements for the vessel salvage and rescue industry, we have redesigned the launching airbags. These can now be used as pontoons for supporting docks and other floating structures, and they are also excellent for pipe-laying and other underwater construction projects to supply buoyancy. But the main application of the “Marine Salvage Airbags” is in shipwreck salvage, floating bridge and dock construction, rescue, and removal of wrecked ships and beached vessels.
Marine Salvage Airbags are very small in size when deflated, and are lightweight. Thus, they can be easily transported and deployed. They can be used vertically to right sunken vessels out of deep water. When the boat is suspended near the surface they can be slung under the boat with one end on each side to raise the boat high enough out of the water to pump it out. In shallow water two bags can be slung together like pontoons, one on each side of the boat. They can also be used as rollers for moving beached boats back into the water, just like our Ship Launching Airbags.
ADVANTAGES
- Special synthetic tire-cord layer material
Our “Salvage Tubes” are made with special synthetic tire-cord layers, which have much better performance than those made with PVC coated fabrics. - High-Pressure Design
Salvage Tubes have a maximum working pressure of 0.25Mpa. That means that they can be used under 25m water-depth. - Holistic Screw Type Enlacing Salvage Airbags
Our “Vessel Salvage Airbags” are a totally enclosed tube with cone ends. It is manufactured using Holistic Screw technology. This design ensures that there aren’t any welded seams. This makes them stronger than RF welded salvage airbags. - Equipped complete with accessories
Our Salvage-Bags are equipped with nylon straps and shackles with 6:1 safety factor.


For extra wide launch requirements the marine airbags can be placed side-by-side.

Acceptance Test for Commercial Ship Launching Airbags
• The appearance of each Evergreen Maritime ship launching airbag is smooth, glossy and without blemish such as crack, blister, delamination, pits, or impurities.
• The length and diameter of each Evergreen Maritime ship launching airbags are measured with the rated working pressure and is within ±3%.
• The gas-tightness is tested without carrying any load as per ISO 14409. The pressure loss is less than 5% of rated working pressure within 1 hour.
Evergreen Maritime ship launching airbags are type approved. This means we have demonstrated the performance of ship launching airbags to independent inspectors CCS. Type Approval Test is the essential and necessary qualification of qualified manufacturer of ship launching airbags. In addition to the requirements for the material, appearance, and dimensional tolerances, “Gas-tightness Test”, “Compression Test”, “Bearing Capacity Test”, “Bursting Test”, and “Compression-recovery Test” are carried out.

Any failure to inspect shall also be deemed a waiver of any rights to revoke acceptance at some future date with respect to any defect that an inspection might have revealed. Purchaser’s acceptance may not be conditioned upon financing of the contract purchase price, negotiation of bank drafts or approval by entities not a party to this contract. Upon acceptance, Purchaser shall be bound by all of the terms and conditions contained herein.
- Purchase Price: The purchase price for each item, and the total contract purchase price for the goods are identified on the face of the Invoice.
- Payment: Unless otherwise agreed by Seller, the total contract purchase price is due and payable upon Purchaser’s acceptance as defined above. Failure by Purchaser to pay the total contract purchase price before or at the time of acceptance may excuse Seller’s obligations under this agreement, at Seller’s option. In the alternative, Seller may agree to accept Purchaser’s promise to pay for all or any part of the goods accepted, but Seller is under no obligation to do so. In any event, if payment of the total contract purchase price is not tendered by Purchaser at the time of acceptance, or in the event that bank drafts offered as payment are not negotiable for any reason, or if for any other reason the total contract purchase price is not paid at the time of acceptance, the total contract purchase price and any other amount due hereunder shall bear interest at the rate of 1.5% per month from the date due, until paid in full. The total contract purchase price and any other amount due to Seller shall be paid in U.S. currency without deduction or offset.
- Delivery: Delivery is accomplished, and Seller’s performance is complete, when Purchaser, either utilizing its own personnel and vehicles or utilizing vehicles which it hires, picks up the goods at Seller’s facility, or, if Seller has so agreed, Seller delivers the goods to Purchaser at the location designated by Purchaser. If Seller engages third parties to deliver the goods, it does so as Purchaser’s agent, with all transportation charges to be for Purchaser’s account and with delivery deemed to occur when the goods are picked up at Seller’s facility. Risk of loss and duty to insure the goods shall pass from Seller to Purchaser upon delivery as defined in this section.

Purchaser and Seller agree that title passes upon Purchaser’s acceptance of the goods, as defined by this contract, regardless of the status of payment. Purchaser agrees to remove from Seller’s premises all goods purchased under this contract immediately upon transfer of title, as defined in this section. Subsequent to such passing of title, Purchaser is solely responsible for any and all risks of liability and any and all risks of loss, which involve the goods sold under this contract, regardless of the location of the goods or the status of payment. The fact that any item sold under this contract is left on Seller’s premises subsequent to passing of title will not be deemed to create a bailment. To the contrary, any goods sold under this contract, which remain on Seller’s premises subsequent to passing of title, is deemed a nuisance, which Purchaser is on notice to remove. Any goods remaining on
Seller’s premises more than thirty (30) days subsequent to passing to title may be removed by Seller, at Seller’s discretion, and at Purchaser’s expense. Purchaser agrees to indemnify, defend, and hold Seller harmless of and from any claim or costs arising from Purchaser’s ownership of the goods subsequent to passing of title.
- Impracticability or Impossibility: Seller shall not be liable for any delay or failure to deliver the goods under this contract which is caused by fires, strikes, labor disputes, war, civil commotion, delays in transportation, shortages of labor or material, breakage of the goods or other causes beyond the control of Seller. The existence of such causes of delay or failure shall justify the suspension of delivery, and shall extend the time of performance on the part of the Seller to the extent necessary to enable it to make delivery in the exercise of reasonable diligence after the causes of delay have been removed. If such causes of delay cannot be removed, Seller’s obligation to deliver is excused.
