Qingdao, China – September 2026 – Qingdao Evergreen Maritime, a trusted and professional manufacturer and exporter of high-quality marine protection equipment, has successfully completed a full-scale Bureau Veritas (BV) inspection and certification process for ten 1.2 m × 2.0 m pneumatic rubber fenders customised for a client in Pakistan. The entire batch passed comprehensive performance verification in strict accordance with the international ISO 17357 standard, achieving full qualification under the supervision of Bureau Veritas (BV). This demonstrates the company’s consistent product quality and standardised manufacturing capacity within the global marine industry.
Pneumatic fenders are critical safety facilities for ship berthing, docking and offshore mooring operations. Their material stability, structural strength, and sealing performance directly impact the safety of vessels and port infrastructure. To fully meet international maritime specifications and the client’s technical requirements, Qingdao Evergreen Maritime conducted a complete set of professional tests covering the five core inspection items required by ISO 17357-1:2011. This ensures that every fender delivers reliable and durable performance in complex marine working environments.
The first of these is the rubber material test, which was strictly implemented in full compliance with the technical parameters specified in ISO 17357-1:2011, Table 3. Key indicators, including rubber tensile strength, elongation at break, hardness, wear resistance, and ageing resistance, were fully tested. All material test results met the required standards, ensuring the fenders have excellent seawater corrosion resistance and anti-ageing performance for long-term offshore use.
The second dimensional inspection accurately verified the overall length, diameter, and structural dimensions of each fender. All dimensional tolerances were controlled within the ISO 17357-1:2011 allowable range, ensuring consistent appearance, accurate assembly and standardised buffer performance of the finished products.
Thirdly, a compression test was performed to evaluate the fenders’ bearing capacity and structural flexibility. The products demonstrated stable structural performance without any abnormal deformation under a simulated compression load, thereby verifying their energy absorption capacity and mechanical stability during an actual berthing impact.

In the fourth air-leakage test, all fenders were inflated to the rated working pressure and kept under continuous observation. No pressure drop or air leakage was found in the main body, joints or seals, proving excellent airtightness and long-term working stability.
Finally, the hydrostatic pressure test simulated extreme underwater pressure conditions to examine the overall structural strength. After graded pressure testing, all fenders remained intact, with no cracks, bulges or permanent deformation, thus fully satisfying ISO 17357-1:2011 safety standards.
The full BV qualification marks another solid achievement for Qingdao Evergreen Maritime in expanding into overseas markets. The company will continue to adhere to international production and testing standards to provide high-quality, safe marine equipment to clients around the world.
