Zhejiang Donghong shipyard launched three cargo ships in one month with airbag ship launching technology. The biggest one is DWT52,000 with unattended machinery space.

Marine airbags are often called ship launching airbags that indicates they are most used for launching ship into water. Inspired by ship launching, people developed many applications of marine airbags in different fields, the most remarkable one is heavy lifting and moving with marine airbags. SPMT stands for self-propelled modular transporter, a platform vehicle with a large array of wheels; it is equipped with Power Pack Unit which provides the propulsion.

The incident involving the vessel "HYSY 682" occurred around 2:00 pm on January 14 at the Nantong Wharf of the shipyard, Wuchang Shipbuilding Industry Company Ltd., in east China's Jiangsu province, the announcement on COSL's official website stated.

Roncheng Xixiakou Shipyard Co has taken out legal proceedings against Wärtsilä for breach of contract, claiming the engine manufacturer knowingly supplied a reconditioned shore-based power generation engine as a new marine engine for installation in a 12 500dwt multi-purpose vessel ordered by Spliethoff Bevrachtingskanoor.

Caisson transportation with marine air bags is a new technology which doesn’t need rails and trolleys and can transport concrete structure on compacted ground. So it enables fabricating caissons on temporary site which can be located near shipping position. Using balloons to transport caissons to submersible barge then launch it can save more than 40 percent investment comparing with trolley transportation method,not mention the time saving.

In the middle of October two Chinese shipyards: Nantong Qiya Ship Engineering Co., Ltd and Huigang shipbuilding went into bankruptcy procedure.

China's largest offshore oil producer, CNOOC Ltd., said on Saturday it has cleaned up the oil sheen on the sea surface in the Bohai Bay in north China.

On September 29th, a luxury leisure boat purported to cost over 17 million RMB sank stern first as soon as it entered the water near Lanzhou city in Gansu Province.

The Sinopacific Shipbuilding Group is a fast-paced, joint venture in China’s shipbuilding industry. They contracted with Jaccar Holdings for six LPG carriers building. That vessel is SINOPACIFIC’s first LPG Carrier which measures 92.5 meters by length and 17.4 meters by width.

On Sep. 2 Eversafe Marine Engineering company successfully re-launched a 6500 m3 LPG Vessel with marine airbags (ship launching balloons) in a Romanian shipyard. That vessel measures by 116 m long and 18 m wide with 3650 tons light weight plus 450 tons ballast water.

20 pieces Eversafe marine airbags (ship launching balloons) were employed to help a DWT5000 sunk vessel refloat.

People who is familiar to airbag ship launching technology may know that in most cases there will be pulling system to prevent vessels from slipping before launch. But if the pulling system is not available due to practical limitation, can people launch vessels with marine airbags? The answer is yes.

On May 29 2011 Eversafe Marine Engineering Company successfully completed a LPG Cargo Tank lifting Project with heavy lifting airbags in COSCO shipyard. That VLGC cargo tank weighs 1600 tons with 40 m length , 30 m width and 20 m height.

On May 21 2011 Eversafe Marine engineering company successfully launched a DWT47000 cargo ship with marine airbags in Nanjin Jinda shipyard. The ship named “ tai he da” weights 9000 tons, measured by 190 m length, 32 m moulded width and 16 m depth . The launch slipway is a concrete ramp with 1/80 slope angle. From end of slipway to the Yangtse river there is a 60 m natural ground paved with gravel. Yangtse river is one of the most busy channel so our launch is strictly limited for the launch time and launch area by local Maritime Safety Administration.

On May 18 2011 ,Eversafe Marine engineering company successfully launched a 37,500 DWT cargo ship with 50 pieces marine airbags in Zhejiang Taizhou shipyard. The vessel named “Dongchengyuan “ measured by 180 m length, 29.2 m breadth moulded and 15.2 m moulded depth. Its lightweight reaches 8000 tons.

Marine airbags are often used for ship launching or hauling out. But most of those vessels are civil; no report of naval ships have be launched or hauled out by airbags before. Once Eversafe Marine contracted a retired submarine haul out project which is said as the first submarine haul out projects with marine airbags.

Caisson structures are widely used in jetty,wharf and levee construction because of their good stability and little underwater construction work. But caissons have to be constructed in special construction factories where there are transport instruments such as trolleys and trials. Building traditional transport instruments is expensive and needs a long construction time. Then in area far from caisson pre-construction factories it comes to be difficult to use caissons for construction. To build temporary construction factories near wanted construction area people need to find an easy caisson transport solution.

One Korean Shipyard located in China Weihai got two ship launching accidents in two years. The first accident happened in 2009 that a new built 6700 units PCTC sunk at launch. And that PCTC have not been salvaged from the sea until the latest launch accident happened.On January 21, 2011 in the same launch area one new built cargo ship grounded when it was launched from a floating dock.

Pulling ships out of water (ship landing) using marine airbags is a very successful application of marine airbags. The basic principle of airbags ship launching or landing is changing the force of sliding friction into rolling friction, just like ancient Egyptian using logs to transport heavies.

SINOPEC is one of the largest integrated petroleum and petrochemical companies in China.Recent years this magnate set foot in ocean oil business which was once monopolized by another oil company CNOOC.

Marine airbags are found to be powerful and versatile tools for many 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.

Marine airbags are unique Chinese marine products and often called ship launching airbags that indicate the most popular application of these heavy duty airbags is for ship launching. It is estimated that more than 80 percent new built ship whose DWT below 60,000 are launched by marine airbags in China.But marine airbags are found to be powerful and versatile tools for many other marine projects such as disembarking ships,heavy transportation, refloating salvage etc.
