Assembly of Neptune Prototype Nears Completion

Assembly of STL’s prototype offshore access system known as ‘Neptune’ is nearing completion.  The photo shows the Neptune foundation and gimbal assembly being flushed with oil prior to installation of the advanced electro-hydraulic proportional valves.  Initially a land based test program is planned.  The program will include testing the motion compensated gimbal assembly on our in-house motion simulator.  Sea trials will follow.
