Envirex/Aker Solutions Subsea WOCS

Multifluid Smart Pump.

The subseaWOCS valve pack is a self contained unit

consisting of 8 pulse operated/controlled DCVs for

controlling 8 hydraulic functions on a subsea tool e.g. an

openwater workover stack or a running tool. The valve

pack is pressure compensated and suitable for us at

3000 water depth.
