Positioning Venture in the Gulf of Guinea19/08/2011
|Watergate Technical Services based in Port Harcourt, Nigeria, purchased two Applied Acoustics' Easytrak USBL tracking systems in 2010 and they quickly became a successful operational tool.|
Prior to the purchase of the tracking system, diver positioning and tracking had been challenging during subsea riser and mattress installations during pipelaying projects. Once Easytrak was deployed, interfaced with GPS and gyro compass, precise positioning and heading determination of the diver and mattress installation frame became much easier. During a recent mattress-laying operation off Warri in the Gulf of Guinea, accuracy of less than one metre was achieved, even when working in a near-shallow environment.
The ability to interface the unit with a navigation computer also makes the operation free of ambiguity as the positioning information can be displayed at strategic offices as well as at the dive shack. This visible confirmation of operations underwater provides the client with all the necessary confidence in the accuracy and efficiency of the Watergate operation.
The company's offshore operations cover the full range of subsea services such as pre-installation pipe route surveys, SEWOP positioning, site hazard surveys, subsea riser and mattress installations. Survey Manager, Ugo Nwangwu, maintains the Easytrak system with its 900 Series Beacons fitting perfectly in their deepwater survey operations in the Nigerian Gulf of Guinea and Bight of Bonny.

How to Use QPS' Qimera to Validate Processed Point Files
QPS Qimera processing software has been released earlier this year. To demonstrate the capabilities, this video shows how to load processed point files into a Qimera Project. It explains what processed point files are; how to specify the coordinate system of the project and the source files; how to create a Dynamic Surface from processed point files and how to change the dynamic surface and adjust the colour map to aid data editing and validation.
