AMPO Poyam Valves has successfully completed and delivered a fully integrated subsea valve system for a leading energy company in South America. The comprehensive ISS (Integrated Smart Solution) enables compressed air transfer beneath the ocean surface and was designed, manufactured, assembled, and tested in Idiazabal to meet demanding technical requirements.
The system includes six highly engineered subsea ball valves installed 365 meters from the shore and 25 meters below sea level, operated by hydraulic actuators. A Subsea Umbilical Termination Unit (SUTU) and subsea connector ensure reliable subsea electrical interconnections. Two 365-meter-long umbilicals supply hydraulic lines and electrical cables linking the final elements with the hydraulic power unit (HPU) and control panel. Junction boxes located onshore support electrical and hydraulic connections.
The HPU powers the valve actuators with a redundant configuration of two motor pumps and two accumulators, enabling valve operation in under six seconds. A redundant control system (RCS) monitors oil volume, pressure, temperature, motor start/stop, and electrovalves. Fully integrated with the client’s control room via TCP/IP, it allows remote operation.
Installed in a seismic region, the HPU, control panel, and supporting structures were reinforced with custom-designed components to ensure safe, reliable operation under extreme conditions. The system offers three operating modes: remote control, local panel control, and manual operation.
