Offshore Foundation Drilling

We provide bespoke pile top and subsea drilling services for challenging seabed conditions, including hard rock socketing, under-reaming, and deep pile penetration. Our drill rigs are designed, built, and operated by the team, offering capabilities up to 9.5m in diameter.

Navigated Challenges

  • Hard seabed refusal requiring socket drilling


  • Foundation installation in locations with poor geotechnical conditions


  • Large-diameter monopile or jacket pin pile installation requiring high torque and stability

Confidence in Delivery

  • Proven performance using RCD rigs from 2.2m to 9.5m

  • Experienced team capable of mobilizing from floating vessels with heave-compensated platforms

  • High torque, under-reaming technology designed to reduce risk and time offshore

Operational Support

We embed alongside your team to provide real-time technical support during installation, whether it’s offshore troubleshooting, construction management, or on-the-fly adaptation to site conditions.

Navigated Challenges

  • Offshore delays due to misaligned expectations between engineering and field teams

  • On-site problems with seabed inclination, casing stability, or hole cleaning

  • Equipment malfunction or adaptation needs under pressure

Confidence in Delivery

  • Direct access to senior engineers and equipment experts

  • Troubleshooting and change management during critical operations

  • Seamless interface between field execution and project planning

Installability & Planning

We support early-stage engineering with detailed assessments of site-specific conditions, equipment compatibility, and foundation feasibility to help developers and contractors plan efficient installation campaigns.

Navigated Challenges

  • Unknown or poorly defined seabed conditions leading to underestimated risk

  • Suboptimal foundation or vessel selection during concept phase

  • Late-stage design changes due to installability concerns

Confidence in Delivery

  • Feasibility studies including cost, schedule, vessel and anchor type evaluations

  • Technical due diligence across equipment, drilling parameters, and risk management

  • Reduced likelihood of unexpected delays, downtime or cost overruns

Equipment & Method Advisory

We provide clients with impartial advice on equipment selection, drilling methods, and tooling—based on over 60 years of experience designing and operating some of the industry’s most advanced rigs.

Typical Challenges Solved

  • Selection of inappropriate drill rigs or tooling for project needs

  • Inefficient or outdated methodologies

  • Equipment or vessel interface mismatches

Engineered Confidence

  • Full lifecycle design input from rig to bit

  • Tailored drilling methods, downhole tool specs, cuttings management, and deployment aids

  • Vendor-agnostic approach ensures optimal, not convenient, recommendations
