Construction Support

We offer construction support to our clients to allow the safe installation of offshore assets. These activities depend upon precise surface and subsea positioning data and accurate data regarding surface and subsurface assets.

Horizon is vastly experienced at performing construction support services for our clients and can help to complete a project on time, in budget and with safe operations.

During construction, support activities such as pipe lay and jacket installation, we can provide a Tug Management System (TMS) on our client’s barges. The system is mobilised onto anchor handling vessels allowing the vessel position, speed and direction to be monitored from the main barge or rig during the activity. Commands for anchor deployment and recovery are also relayed through this system.

We provide a comprehensive range of positioning and construction support services for the following activities:

  • Survey support during pipe-lay
  • Survey support during PLEM installations
  • Survey support during SPM installations
  • Survey support during hook-up work
