LoggingLogging possibility on all sensorsConfigurable sampling period setupHigh definition graphs Automatic generated reports
Envirex Group’s multipurpose subsea intervention systems are special developed to simplify well access, well intervention and work over operations from any type of rig or vessel.
Extreme Capex & Opex reductionReplaces 100T deck equipment (MCU, HPU, Reels and umbilicals ++)Allowing use of LWI Vessel instead of Drilling RigPlug & Play – Enables control of LWRP without use of umbillical and requires no modification on subsea assetsUmbilical less use, operated thru ROV
Key Benefits
Reduced mobilization time and costReduced POB (people on board)Reduced operational timePlug & Play – Enables control of LWRP without use of umbillical and requires no modification on subsea assetsSafe and reliable operationIncreased weather window
