Description
Dock Rubber Fender for shipyard launching and construction operations is specifically engineered to withstand extreme static loads and dynamic forces generated during vessel launching, shifting, and early-stage outfitting. Unlike conventional quay fenders used for routine berthing, this type of dock rubber fender must perform under prolonged compression, uneven load distribution, and high surface pressure while maintaining dimensional stability.
Hongruntong Marine’s shipyard dock rubber fenders are produced using reinforced natural rubber compounds with enhanced hardness gradients, allowing controlled deformation under heavy loads. The product range includes block-type, cylindrical, and laminated rubber fenders that can be customized in size, hardness, and internal reinforcement to suit different launching methods such as slipway launching, skid launching, and side launching. These fenders effectively protect hull plating, dock structures, and launching equipment, ensuring safe and controlled vessel movement throughout construction stages.
Case Study – Newbuild Tanker Launching Project
A shipyard in Eastern China specializing in 30,000–50,000 DWT chemical tankers faced repeated hull coating damage during skid launching due to uneven load transfer and insufficient cushioning. Hongruntong Marine provided custom-designed dock rubber fenders with increased contact surface area and optimized hardness distribution. During subsequent vessel launches, hull stress concentrations were significantly reduced, coating damage was eliminated, and launching alignment improved. The shipyard successfully reused the fenders across multiple projects, achieving measurable cost savings and improved safety records.

Features
High Static Load Endurance
The fender structure is designed to operate under long-duration static compression without permanent deformation, making it suitable for prolonged vessel support during construction and launching phases.
Controlled Elastic Deformation
Advanced rubber compounding ensures predictable deformation behavior, allowing shipyard engineers to accurately calculate load distribution and launching forces.
Reinforced Internal Structure
Optional steel plates or fabric reinforcement layers improve dimensional stability and resistance to shear forces during vessel movement.
Surface Protection Performance
The smooth yet wear-resistant surface minimizes friction damage to hull coatings and steel plating.
