Positioning & Construction Support

CONSTRUCTION BARGE & AHT POSITIONING
EGS offers marine construction contractors various different options for construction barge positioning including stand-alone vessel positioning and remote anchor management systems.

Using high accuracy Differential GPS positioning and heading systems installed on both the barge and anchor handling vessels, EGS provides a safe, reliable and cost effective solution. With the addition of a broadband connection on the barge, a remote link can be setup allowing remote monitoring and QC from the shore base office.

HIGH ACCURACY SUBSEA POSITIONING
In addition to high accuracy surface vessel positioning, EGS owns a range of acoustic tracking and measurement equipment, that can be seamlessly integrated into the barge or installation vessel’s survey systems.

Combined together, Ultra Short Baseline (USBL) and Long Baseline (LBL) equipment provide a high accuracy solution for subsea positioning including ROV operations, diver-less metrology and spool piece design. For high accuracy positioning of ROV in deepwater environments, Inertial Navigation Systems (INS) can be integrated with LBL and other sensors to provide a solution to ensure the client’s specifications are achieved.

In addition, EGS offers a full range of construction survey, project management and inspection capabilities including:
