Structure

Ship launching airbags are constructed of an outer rubber layer, multilayer synthetic-tire-cord layers, and inner rubber layer vulcanized firmly. In addition, the rubber airbags are cylindrical balloon body, with two conical head and end mouth.

1) Identifying the type, size & weight of the vessel before you launch.
Main factors like types, sizes, vessel weight, working height (distance between the hull of the ship and ground) affects your choice of airbags. The main structure of vessel is vital in determining the placement of the inflatables too.

2) Type, length and number of airbags have to be chosen carefully.
The dimensions of rubber inflatables in terms of diameter, length and layers determine its lifting/bearing capacity. The inflatables will have a longer lifespan in the long run because they are used well within their lifting capacity.

3) Ground structure/ slipway has to be free of sharp objects and preferably, a small degree slope.
First and foremost, a hard ground is a must to have a safe and successful launching. Additionally, the launch way must be free of hard & sharp objects like sharp metal plates, big stones etc. These may damage the rubber launching bags during launching.

4) Slipway Winch to provide pulling force needed.
A slipway winch is needed to hold the vessel in place (prevent it from slipping into the water) during the placement of airbags. Slope angle, weight and type of ships should be carefully considered to determine the winch capacity. A choice of electric winch or hydraulic winch also depends on the facilities of the shipyard and the aspects of its usage.

5) Determine the accessories needed for ship launching using airbags.
Accessories like pulley blocks, shackles, steel wire rope and shackles may be needed. The types of accessories and volume depends on the situation.

6) Determine whether a slow launch or quick launch.
For trickier situations, a slow launch may also be practised. This is where the winch slowly releases the rope and the vessel is allowed to slide slowly. For slow launches, the balance of the ship is ensured so if at any point of time it falls out of balance, the winch will be immediately stopped and corrections can be made.

Before to provide suitable airbag size and quantity for your ship, please provide below information:

1.Ship length,width and weight.

2.Type of ground ship is built on? (Dirt, concrete, etc.)

3.Type of ship?

4.Depth in meters of the water where the ship first enters the water?

5.What's the angle degree of slipway? (Land, not under water)

6.Please provide the low/high tide schedule at site.

7.The working height? (The block stand height under the ship)

8.Distance from bottom of propeller to the water level?

9.Distance from back of ship (in dry dock) to the water entry point?

*If possible, please provide photos of the launch area.

When a marine airbag unused for a long time it should be washed and dried, covered and filling up with talcum powder, then put it in a dry, shade and ventilated place, keep away from sources of ignition.
