5 Most Common Marine Salvage Airbags
The 5 most common marine salvage airbags include totally enclosed lifting bags, marine rubber airbags, pillow type flotation bags, steel pontoon, and open parachute type underwater air lift bags.
How to use inflatable lift bags?
What is inflatable lift bags? Inflatable lift bags is one kind of all-purpose buoyancy units. All underwater lift bags and marine salvage bags can be called inflatable lift bags. There are many types of inflatable lift bags. Such as parachute type, totally enclosed type, pillow type, elongated pontoon type, dual boom, and others. These lift bags have different application. Parachute type lift bags can be used for the underwater [...]
Water Weights Proof Load Bags
DOOWIN engineering team successfully finished another crane load testing project using our water weights proof load bags. We provide proof load testing services and water bags to buy or rent to companies across China and throughout the world. We are stocking many different size water weights bags and load cell. Our experienced engineer team can contract any load testing projects.
World’s First Seabed Flexible HDPE Pipe Double-tube
DOOWIN pipeline buoyancy units were used for the world's first ultra-large and ultra-long HDPE double-tube shipping and installation. Recently, a super flexible HDPE submarine pipeline with a length of 558.2 meters and a weight of 1,315 tons was commercialized at the commercial port of the Saudi Arabian Sea City. It successfully adopted double-tube shipping to achieve seamless underwater docking and became the world's first super flexible HDPE submarine pipeline. Double [...]
Potable Water Pillow Tanks

Low Headroom Crane Load Test
Our esteemed customer KONECRANES finished another 150 ton crane load test. This crane has low headroom working height. In order to reach the rated load testing weight within limited height, have to design the special low headroom water bags. The point is normally the height of empty is longer than the height filled with water. After doing much calculation, our engineer design fours PLB-40ton water bags according to the [...]
Mono Buoyancy Units Assist Pipeline Installation
From the news of CHEC Jazan Integrated Gasification Combined Cycle Project water intake and outlet project Saudi Arabia, the last part HDPE pipeline was jointed underwater successfully with the help of mono buoyancy units. It marks the success of the installation of the world’s longest and most flexible pipeline. HDPE pipeline installation is the biggest risk point of whole project. Because it is the first world’s largest diameter and [...]
Inflatable Pipe Floats Buoys
Recently, we designed one kind new arc-shaped pipe float buoys. This type pipe float buoys can connect with the pipe closer to get more buoyancy in the shallow water condition. We can make pipe float buoys according to the different diameter pipe. The buoyancy is from 1ton to 10ton each unit. Arch-shaped pipe floater has three lifting webbing sling. So pipe laying float can be strapped to the pipeline to reduce [...]
Water Filled Weight Bags for Crane Load Testing
Water filled weight bags is recognized worldwide as the most effective and safest crane proof load testing solution. Crane load test water weight bags provide an easy, safe and highly cost-effective crane load test weights solution for the load testing all kinds of lifting equipment.
Underwater Air Lift Bags Salvage Ships
Underwater air lift bags salvage is professional marine salvage bags used for vessel salvage, floatation salvage. Better performance than flotation bags. We have all types of marine salvage airbags for sales.
