SEATOOTH ACFM Subsea Smart Wireless Crack Monitoring

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 is a well-established tool that can be installed on offshore structures to monitor the growth of surface breaking cracks. SEATOOTH is an established subsea wireless communications system that provides reliable communications through seawater and through the splash zone. Seatooth is immune to biofouling, surface noise and turbidity.

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. Seatooth ACFM units are user-configured to take readings as required, from once a minute to once per month. 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 on shore. SEATOOTH ACFM systems come with an internal battery pack to support 5-15 years of operation and are installed by light-class ROV deployed off platforms.
