    TUBUS Shock Absorber by ACE: a Custom Solution for the Offshore Industry

A few years ago, damping specialist ACE Stoßdämpfer GmbH introduced a new type of shock absorber that can cope with almost all offshore industry challenges—the TUBUS shock absorber. A revolution in damping technology, making problems such as corrosion and oil leaks a thing of the past. A long service life characterises the TUBUS shock absorbers by ACE.

TUBUS is a unique product. It is produced from a high-performance TPEE material with special characteristics. The parts are produced in a two-step operation. After the injection moulding process, the molecules are stretched, resulting in the product's shape and performance. "There are no fluids involved, and therefore it is perfect for offshore application. Water pollution is impossible," according to Han Titulaer of ACE Stoßdämpfer. The material has a good resistance against chemicals, oils, pollution, temperature, and UV; it will not rust and is extremely ageing resistant. The TUBUS shock absorber is also more cost-effective compared to hydraulic alternatives.

TUBUS dampers can be used to absorb shocks, control vibrations and protect systems. More specifically, TUBUS shock absorbers excel in high energy absorption, are lightweight and are maintenance-free. TUBUS systems can be used in both light and extremely heavy applications. Another benefit is their long service life. 

TUBUS dampers can be used in safety-stop applications, as well as in applications with continuous operation. The low weight dampers can absorb high forces on a small installation space. They can be found on workboats moored at offshore wind parks and in harbours. The forces during docking are often too high for the working vessel's polyester structure. A movable construction and TUBUS dampers were implemented to limit the forces and absorb energy to prevent further damage.

They are also used on one of the largest passenger ships built at Meyer Werft. The lifeboats are protected by a TUBUS bumper, which is used when lowering lifeboats into the water. The hard contact to the water in rough weather requires a high performing damper with excellent resistance against saltwater and UV radiation.
