Successful subsea intervention at Oseberg South!
A major project and a great example of what strong collaboration can achieve!
Together with our valued partners Beluga Subsea AS, IK Group, Subsea7 and Semar AS, SubseaPartner successfully completed a diving intervention campaign at Oseberg South, installing repair clamps on a caisson.
The operation combined LDC diving, ROV and Variable Buoyancy System (VBS) technology, supported by MV Seven Viking and the Oseberg South topside team.
Working at water depths of approximately 9–24 metres, the scope included:
▪️ Involvement in the final clamp design
▪️ Subsea deployment, positioning and installation of repair clamps
▪️ Bolt tensioning
▪️ As-left surveys to verify completed installations
▪️ Temporary patch repairs on caissons
The VBS proved highly effective in handling the clamps subsea, enabling controlled installation while reducing the need for conventional crane operations.
Close coordination between the diving team, ROV crew, marine personnel and topside team was key to ensuring safe and efficient ex*****on throughout the campaign.
A big thank you to Subsea7, Beluga Subsea AS, IK Group, Semar AS and everyone involved for the excellent teamwork and contribution to a successful project!
