Surface Positioning

Surface positioning is at the core of our surface to subsea services.

Over more than four decades our highly experienced survey personnel, using high-end technology, have provided surface positioning to the global offshore energy industries.

Our surface positioning services include:

  • Vessel positioning
  • Rig positioning
  • Tug management packages
  • Structure installation
  • RTK and GNSS positioning

Each project is treated separately and following a full review of specifications, project specific procedures are written and issued to the customer for review. These procedures, backed-up by our well-established generic documents, are guidelines for our offshore teams and a quality control measure for our customers.

High Specification

We use high specification and industry standard equipment and software on all our projects. As each project is different, we work closely with customers taking into consideration the job requirement, budget and expectation, to ensure we deliver the best fit survey spread.

Our rig positioning and tug management packages are compact custom-built in-house systems that ensure a high degree of autonomy with a plug and play set-up. This ensures our packages are easy to deploy and set-up onboard rigs and tugs anywhere in the world.



Full RTK Solutions

In addition to our high accuracy GNSS we also offer a full RTK solution. Our track record includes the supply, installation and maintenance of RTK for offshore wind farms including onshore base stations and offshore rover packages. We have off the shelf RTK systems available for fast deployment.
