INTRODUCTION SPT Offshore SPT Offshore is the leading offshore contractor for suction pile anchors and foundations. SPT undertakes and manages EPCI project worldwide from suction pile anchors for moorings and pipelay startup, suction pile foundations of jackets and subsea structures to complete Self Installing Platforms (SIPs), Self Installing Monopiles (SIMs) for platform extensions and Suction Installed Wind Turbines (SIWTs). Furthermore, SPT Offshore provides suction piles, Suction Pile Clusters (SPC) and Suction Embedded Anchors (SEA) for the mooring of floating units (FPSOs, MOPUs, buoys, FSUs, etc), subsea structures and subsea pipelines. Our scope covers pre-feed concept studies, FEED studies, detailed design, fabrication, transportation and offshore installation. Our design staff includes pre-dominantly MSc. level engineers including the geotechnical, structural, naval and marine disciplines. Our operational staff is very experienced in order to ensure that the offshore activities are performed safely and efficiently. This project track record highlights several of our projects in the following categories: Self Installing Platforms (SIP1 and SIP2) Self Installing Monopiles (SIM) Suction Installed Wind Turbines (SIWT) Jackets with suction pile foundations Suction piles for moorings Suction piles for pipelay startup and SCR anchoring Suction piles for the foundation of subsea structures A complete list of all projects by SPT Offshore can be found at the end of this track record. 2
