FULLY INTEGRATED SUBSEA VALVES AND A MOTION CONTROL SYSTEM FOR A SOUTH AMERICAN MINING PROJECT

AMPO POYAM VALVES has successfully completed and delivered a fully integrated subsea valve system for a leading company in South America. The complete ISS system (Integrated Smart Solution) enables compressed air passage under the sea, off the coast, and was designed, manufactured, assembled, and tested in Idiazabal to meet the client’s demanding requirements.

The system includes:

• Final Elements: Six highly engineered subsea ball valves installed 365 meters from the shore and 25 meters below sea level, operated by hydraulic actuators.
• SUTU (Subsea Umbilical Termination Unit) and Subsea Connector: Ensures subsea electrical interconnections.
• Umbilicals: Two 365-meter-long subsea connections of hydraulic lines and electrical cables linking the final elements with the HPU and control panel.
• JB (Junction Boxes): Onshore units for electrical and hydraulic interconnections.
• HPU (Hydraulic Power Unit): Powers the valve actuators with a redundant system of two motor pumps and two accumulators, designed to operate the valves within six seconds.
• Redundant Control System (RCS): Monitors oil volume, pressure, temperature, motor start/stop, and electrovalves controlling the hydraulic actuators. Fully integrated with the client’s control room via TCP/IP, it enables remote operation of the subsea valves.

Installed in a seismic area, the system’s HPU, control panel, and supporting structures were reinforced with a specially designed structure to ensure safe and reliable operation under extreme conditions.

The system offers three operation modes: remote control from the client’s control room, local control panel operation, and manual mode.

This achievement highlights AMPO’s expertise in delivering customized ISS solutions, truly a place where intelligence meets valves.
