The assignment
Connecting engineering with offshore operations
The subsea drilling system was developed to create seabed sockets for offshore wind turbine foundations. Terra provided technical and managerial support for its engineering development, assembly and operation.
The work brought together practical mechanical engineering, supervision and the coordination required between vendors, subcontractors and the wider project team.
Terra’s contribution
Three connected areas of support
Technical supervision
Supervision of mechanical assembly, supported by the preparation of technical processes and procedures and coordination with equipment vendors.
Operational oversight
Oversight during assembly and drilling activities, bringing practical engineering input into the day-to-day requirements of the offshore operation.
Reporting and interfaces
Daily progress, fault and QHSE reporting to project stakeholders, alongside coordination with subcontractors and the wider project team.
- 01Technical processes and procedures
Documentation prepared to support the assembly and operational scope.
- 02Daily project reporting
Progress updates, fault reporting and quality, health, safety and environmental information for project stakeholders.
- 03Project coordination
Communication across vendors, subcontractors and operational teams as the scope developed.
