WFS Technologies, TSC Introduce Seatooth ACFM

WFS Technologies and TSC have launched Seatooth ACFM, a wireless smart NDT monitoring solution designed to reduce subsea inspection costs.

TSC‘s ACFM array probe range can be installed on offshore structures to monitor the growth of surface breaking cracks.

Seatooth is a subsea wireless communications system that provides reliable communications through seawater and through the splash zone.

Combining the technologies together, ‘Seatooth ACFM’ is a non-intrusive, easy to deploy wireless network solution which can be retro-fitted to offshore structures and subsea assets, the company explained.

Seatooth ACFM can be configured as standalone sensors or within subsea wireless networks. As standalone devices, information is harvested by fly-by ROV or a diver. When configured as a wireless network on offshore platforms, real-time data is streamed wirelessly through the splash zone to an asset management control station located either on the platform or onshore, for ongoing live monitoring, the company added.

“The ability to easily install the sensors to monitor aging assets means that the benefits of ACFM technology can now be offered even in the most challenging of environments. The ACFM technique has received approvals from various organisations including DNV, Bureau Veritas, Lloyds Register and ABS. Standard practice documents covering ACFM have been issued by ASTM (E2261-03), ASME V and COFREND,” said David Parramore, TSC’s engineering and operations director.

Brendan Hyland, chairman of WFS Technologies said: “Seatooth ACFM delivers substantial cost savings to our customers along with improved quality of information. It is an essential tool for ageing asset management and lifetime extension strategies.”
