NOTODDEN, Norway —Optime Subsea’s electric subsea controls and intervention light system (eSCILS) has completed its first program for Aker BP at the Alvheim Field in the Norwegian North Sea.
The system was deployed for a completion operation for two production wells. It is an umbilical-less upgrade of Optime Subsea’s subsea control and intervention light system (SCILS), powered by a battery and communicating wirelessly.
Following commissioning onboard the Odfjell Drilling semisub Deepsea Nordkapp, the eSCILS underwent successful wet/sea tests with an umbilical, in ROV mode and other interfaces.
It was then applied to the two dual multi-lateral wells, Frog M-5 and Frog M-6, with interface to Aker Solutions’ subsea trees. It remained in service for about three weeks, performing two batch completions with a subsea jump between the two wells.
The eSCILS comprises a closed-loop hydraulic system with dual seal test system, electric interface with subsea batteries (42kWh) and a fully redundant control system.
