Subsea Structure Installations

iSURVEY provides accurate and precise subsea positioning solutions for subsea template and structures installations. We have a proven track record of installation, calibration and utilisation of a variety of LBL (Long Baseline) systems.

CAN Installations

Where the subsea position, heading, inclination or height of a wellhead / guide base is required, iSURVEY can obtain high accuracy positioning using Long Baseline (LBL) systems for positioning of wells / wellhead guide bases in deep water. These LBL arrays typically consist of 4 or 5 transponders with a topside system on the rig or drilling vessel. Position reference is obtained from range-range geometry from the transponder locations.

ROV Operations

Focusing wholly on survey and positioning services allows iSURVEY to support ROV contractors in a variety of operations, from simple subsea positioning during intervention or basic visual inspection, to more complex installations, measurement and marine support operations.
