In 2020 and 2021 FOX Subsea has supplied RWOCS AHPU and Remote Onshore Support for two fluid injections campaigns on the OCTP ENI Field, Ghana.

For both of the Ghana offshore campaigns, RWOCS AHPU has been made ready on time for pickup and worked successfully in operation. At the time of movement restriction and COVID-19 lockdown, remote support and training was given to Baker Hughes Field Service Engineers to operate the RWOCS. The operations was carried out successfully. No down-time was associated to the RWOCS AHPU and no LTI. Remote Onshore Support assistance was provided by FOX Subsea from Norway Mission Control Center.
