Requirements for Offshore Technology
Long service life, extreme corrosion resistance and simple handling under adverse conditions – these are just some of the demands made on quick coupling systems by the offshore industry. Furthermore, the design of couplings for underwater application must be suitable for handling by divers or ROV manipulators. Click here to learn more about offshore & subsea technology.
Walther’s Solutions
Our quick coupling systems allow for fast connection and separation of fluid, gas and electrical lines on drilling platforms and subsea. Special sealing systems ensure leak-free operation in order to protect the environment. Power assisted locking systems allow for convenient handling of couplings with large nominal bores. Our couplings have proven their worth in remote-controlled systems at great ocean depths. Special sealing technologies and materials achieve a service life of 25 to 30 years.
