Product Description

Inflatable marine airbags are available in customized lengths and diameters, making them highly adaptable to small shipyards, fishing harbors, and repair docks. Their lightweight design enables easy handling and deployment by small teams.

Case Study: In a small Indonesian boatyard, a builder of fishing vessels required compact airbags for 200-400-ton ships. Standard-size airbags were too bulky for the narrow work area. The company ordered 6 custom-diameter airbags, which fit perfectly under the vessels and enabled frequent launch and haul-out cycles with minimal labor and space.
