Subsea Construction
Sonsub has an advanced capacity to provide subsea construction services, including:
 |
Small diameter pipelines, umbilicals and cables |
|
Subsea templates and manifolds |
|
Subsea production systems |
|
Rigid and flexible tie-ins |
|
Trenching, ploughing and backfilling |
|
Testing and precommissioning |
|
Survey, positioning and geo-technical investigations |
Tie-ins are completed either by divers or using one of Sonsub’s subsea remote tie-in systems (BRUTUS or DFCS). We also utilise third party tie-in systems where appropriate.
Sonsub operates a number of long term, specialised construction vessels to provide support to such activities.
