Ashtead, Newton Labs Undertake Underwater Inspection for Subsea 7

Ashtead Technology has delivered an advanced subsea laser scanning project for Subsea 7 on Chevron’s Captain field located in the UK North Sea.

The scope of work included an internal casing inspection and a horizontal mapping survey to capture more than 100 short and long range scans. This allowed Ashtead to generate a 3D model of the structure.

The project saw Ashtead carry out a well inspection utilizing Newton Lab’s M210UW and M3200UW subsea laser scanning systems.

The contract marked Newton Labs’ first subsea project using its M3200UW laser scanner. The system can operate with either a scanning or a fixed laser line to measure underwater objects to 0.02 millimetre accuracy.

In addition, the short range M210UW scanner was used to deliver high-detailed underwater inspection and measurements by optical triangulation.

Allan Pirie, chief executive of Ashtead Technology, said: “In response to market demand, we continue to invest in the latest subsea equipment, working with leading manufacturers to provide the technology our customers need.

“This project was a great example of how the supply chain can work closely with operators to design and engineer bespoke solutions to complex challenges.”
