Support Vessels
Massive, highly efficient, high density seismic operations such as those carried out worldwide by the PGS fleet are dependent on reliable support vessels. They act as transport and accommodation during crew change, and refueling vessels during long projects. PGS charters four purpose-built, seismic support vessels from PF Thor.
