Walther subsea control system underwater couplings are designed and manufactured to meet the rigorous demands of the offshore industry, supplying both mono and multi coupling systems for platform and underwater use. For underwater operation, Walther subsea coupling designs have been modified for easier diver handling. ROV operated couplings have been also been developed for shallow and deep water environments. Walther quick connect coupling systems ensure fast, safe connection and separation of control system lines on topside and subsea structures.
Walther subsea control system couplings are distinguishable by the "coupling actuator" to include: stab plate, cartridge, and ROV multi and couplings. Coupling specifics can be found by following the links.
