Technical Specifications
Materials: Multi-layer synthetic rubber (NR/EPDM blends), high-strength cord reinforcement, abrasion-resistant outer cover.
Standard Diameters: 0.5 m — 3.5 m (custom diameters available).
Standard Lengths: 3 m — 25 m (modular sections can be butt-joined for longer runs).
Working Pressure: 0.05 – 0.3 MPa (design dependent — consult for vessel-specific settings).
Load Ratings: Configurable per vessel weight; typical design tables available for hull weight vs. number of airbags.
Temperature Range: −40°C to +80°C (compound dependent).
End Details: Integrated lifting eyes, protective chafe sleeves and connection flanges for inflation/monitoring.
Accessories: Electric/air-driven inflation sets, pressure gauges, protective mats, chocks and skids.
Exact specifications and recommended airbag quantities are determined by vessel weight, hull shape, slip angle and launch method — provide project details for a tailored datasheet.
Ship Launching Airbag Price — Guidance & Factors
We provide competitive ship launching airbag price quotes tailored to each project. Key factors that influence price:
Airbag diameter and length (larger bags cost more material).
Number of airbags required (based on vessel weight and safety factor).
Rubber compound and reinforcement specification (higher-spec compounds increase cost).
Accessories and kits (inflation pumps, gauges, chafe protection, transport pallets).
Inspection, testing and certification requirements.
Shipping destination and required lead time.
To obtain an accurate ship launching airbag price, send vessel LOA, full displacement (weight), hull form (flat/rounded), desired launch method and delivery location — we will return a formal quotation with recommended airbag layout and total project cost.

Execute controlled skid/launch with winches or natural slope; monitor pressure and alignment.
After launch, deflate slowly and recover airbags for inspection, cleaning and storage.
FAQ
Q1: What is a ship launching airbag and how does it work?
A1: A ship launching airbag is a cylindrical, high-strength inflatable used to support and roll a hull from slipway or transport cradle into water. Airbags distribute load and enable controlled sliding or rolling during launch.
Q2: Can a boat airbag be used for both launching and hauling?
A2: Yes — boat airbag units are commonly used for launching, hull recovery and short-distance transport/hauling when properly sized and configured.
Q3: How many airbags do I need for my vessel?
A3: Number depends on vessel displacement, hull length and distribution plan. We provide load calculations and a recommended count as part of the quotation process.
Q4: Are airbags reusable?
A4: Yes — with proper handling, cleaning and inspection, marine airbags are reusable for multiple launch cycles. We offer refurbishment and spare parts services.
Q5: How do I get a ship launching airbag price?
A5: Provide vessel length overall (LOA), displacement (weight), hull type and delivery location. We will return a detailed ship launching airbag price including recommended airbag types, quantities, accessories and delivery lead time.
