DOLPHIN MARINE offers marine fendering systems to a global market. Our Yokohama type fenders, or pneumatic fenders, fully protect your vessel during ship to ship operations.
Yokohama type Fenders have been in use for around 50 years. It is the leading anti-collision device for marine application in the world. This compressed air filled rubber fender is used as a protective medium for ship-to-ship contact (STS), ship to quay (STQ) and ship-to-berthing (STB).

Yokohama Fender Specifications and Performance
The guaranteed energy absorption of yokohama fenders are the energy absorption at 60% deflection. This value can be use in engineering design and actual operation. Table gives the sizes, weights and technical performance of floating-type yokohama rubber fenders.

Major Strengths of Yokohama Fenders
● High safety level: can stand maximum pressure up to 4 times that of the operating pressure.
● Easy maintenance: just need inflation once every six months.
● Low transportation cost: can be deflated and folded for transportation, thus saving about two thirds of the transportation cost.
● Long lifespan: it is guaranteed that our fenders can be used for over 10 years under normal conditions.
