TEK-Ocean’s client had lost communications with several shut-in subsea assets and requested a solution to re-establish communications with the subsea control modules (SCM).
Determine method of re-establishing communications with use of an electrical downline (EDL) and plugging into the SCM via subsea electrical connector.
Identify a Master Control System (MCS) with the appropriate software that is capable of communicating with the 20-30 year old SCMs.
Conduct an offshore campaign to implement system and re-establish communications.
Identified that existing platform MCS were operable and suitable for communicating with SCMs. The MCS was removed from original offshore installation and modified to be a portable system. A purpose built EDL was provided.
Conducted onshore systems integration testing to confirm continuity, insulation integrity and to ensure that the software will appropriately interpret the signals that are received from the SCM’s.
Conducted vessel campaign to deploy EDL and plug into SCMs.
Interpret data received from SCMs to determine the internal status of the asset.
