World-first offshore anchor pile installation using drill rig with motion compensation platform in the Caribbean Sea

Integrated project delivery tackles complexity 

To support this complex operation, we delivered a complete solution, including 

• Geophysical and geotechnical survey work
• Seabed assessment and analysis
• Design and engineering applicable to the pile installation
• Pile handling, mobilisation, and drilling
• Pile grouting of seven piles
• Diving support and construction vessel (DSCV) charter, offshore crew and project management 

Menck, Acteon’s Marine Foundations business line, mobilised their grouting plant from the DSCV’s back deck, enabling rapid execution -completing each pile’s grouting in under 24 hours. The whole solution, including the drill, was entirely bespoke to project demands. 

Throughout the project, we provided Imodco Terminals with a single point of contact, which simplified tendering, commercial negotiations and contractual dealings and avoided potential gaps between service providers. 

Innovations in action

We integrated our reverse circulation LD2500 drill rig with a motion compensation platform, allowing the drill system to maintain a constant and stabilised position in relation to the seabed. The project proved that drilling could be achieved from a floating asset using motion compensation – a world first. 

The result 

Our advanced anchor pile engineering and installation methods allowed Imodco Terminals to successfully install the catenary anchor leg mooring (CALM) buoy at Limetree Bay to facilitate the reliable transfer of products from very large crude carriers to an onshore facility. The all-around customised solution overcame a challenging offshore environment - delivering a world-first achievement, while simplifying client engagement and completing the project safely and reliably.
