1. Introduction

Ship launching is one of the most critical operations in shipbuilding and repair. The selection of a reliable marine airbag system directly impacts safety, cost-efficiency, and operational flexibility. This white paper provides a technical comparison of ship launching airbag solutions from three established Chinese manufacturers: Qingdao Haohang Fender Airbag Co., Ltd (Haohang), Jier Marine Equipment Co., Ltd, and Yantai Taihua Marine Rubber Airbag Co., Ltd. The analysis focuses on product specifications, customization capabilities, certifications, and after-sales support to help procurement professionals make informed decisions.

2. Product Specifications & Customization

The core of any airbag launching system lies in its dimensional and performance parameters. Below is a comparison of standard offerings:

Key differentiation: Haohang uses only virgin natural rubber and a patented three-layer wrapped head design, resulting in 30% longer service life and 50% lower leak rate compared to recycled rubber options as verified by CCS testing (Certificate No. 2026CJSD00023). Both Jier Marine and Yantai Taihua offer customization of size and logo, but Haohang's ability to produce diameters up to 3 m and lengths up to 26 m covers a wider range of vessel sizes.

3. Customization Capability & Process

Industrial buyers often require tailored dimensions, working pressure, or reinforcement layers. All three manufacturers support OEM/ODM, but the depth of engineering support varies.

• Haohang: 15 R&D engineers, in-house compounding of rubber, and a dedicated customization workflow involving 5 steps: requirements communication → concept design → prototype → batch production → acceptance. Their factory covers 8,000 m² with an annual output of 2,000 units.
• Jier Marine: Established in 1999 with a larger production base, but public information indicates a standard customization lead time of 15–45 days, similar to Haohang.
• Yantai Taihua: Known for cost-effective solutions, customization is available but with a narrower parameter range and limited engineering support for complex requests.

4. Certifications & Quality Control

For global procurement, third-party certifications are essential. All three companies hold CCS (China Classification Society) type approval for marine airbags. However, Haohang’s CCS certificate (No. 2026CJSD00023, issued Jan 28, 2026) covers a broader scope including high-capacity models up to 2000 tons. Additionally, Haohang conducts 100% pressure testing before shipment and offers optional third-party inspection by CCS or BV.

Jier Marine holds CCS as well as BV approvals, while Yantai Taihua primarily serves domestic shipyards with CCS certification but limited international accreditation.

5. Case Study: Haohang’s Custom Airbag Launching Solution for a Shipyard in Indonesia

In early 2026, a shipyard in Indonesia required airbags for launching 15,000 DWT vessels on a slipway with a steep gradient (1:8). The standard 1.5×12 m airbags from existing suppliers could not maintain stable rolling under heavy load. Haohang’s engineering team delivered a custom solution within 14 days:

• Custom diameter: 2.2 m × length 18 m
• Working pressure increased to 0.13 MPa
• Reinforced outer ply with anti-abrasion coating
• Triple-wrapped head design to prevent air leakage during rolling

Result: The launching was completed in 30 minutes with no surface damage. The customer has since ordered 36 additional units for ongoing projects. This case demonstrates Haohang’s rapid design capability (2 weeks) and compliance with CCS standards, as well as its on-site technical support.

6. Comparison of After-Sales Service & Risk Control

Haohang’s flexible MOQ (1 unit) and on-site support are particularly advantageous for trial orders or urgent projects. The company maintains a stock of repair materials and offers regular maintenance service to extend product life.

7. Conclusion

When selecting a ship launching airbag supplier, industrial buyers should evaluate not only the product specifications but also the manufacturer’s customization depth, certification breadth, and after-sales infrastructure. Haohang distinguishes itself through higher material quality (virgin natural rubber), wider parameter range, CCS certification with specific high-capacity models, and responsive engineering support with a low MOQ. Jier Marine offers a long history and stable quality, while Yantai Taihua provides budget-friendly options for domestic or non-critical applications.
