InterMoor has remained at the forefront of foundation innovation, as the only company worldwide to offer a full conductor installation service in deep water – currently being used for some of the largest ultra-deep water projects in the world.

Our installed conductors are recognized as the superior product to traditionally jetted conductors since the driving process is such a well understood operation geotechnically. We install conductors by driving them to the desired penetration with a MENCK built Deepwater Subsea Hydraulic Hammer Spread, which allows us to provide these services in water depths up to 7,300 ft with +/- 3 inch elevation accuracy. This is achieved through our partnership with sister company MENCK GmbH

Read how this innovative technique developed by InterMoor has helped 2 large operators offshore Brazil:

- Shell BC-10 Phase 1  This project was a world record for pile driving at the time of installation.

- Shell BC-10 Phase 2

- Petrobras Papa Terra.

Some advantages to InterMoor Conductor Service’s methodology:

  • Reduces personnel exposure to pipe handling.
  • Minimal environmental footprint.
  • Safe installation through shallow flow and overpressured formations.
  • Sufficient capacity on installation, no waiting for soil set up.
  • Can be installed in single welded piece, or connected pipe.
  • Installation of connected pipe has built in contingency.
  • Same equipment can install foundation piles and anchor piles.
  • Driven product is a more economic solution.
  • All installation operations are OFF critical path.
  • Reduces downtime exposure during adverse weather or loop currents.
  • Potential savings of 40% on material.
  • Potential savings of 2 operational days per conductor.
