TotalEnergies CLOV3 — pipeline walking

OIS qualified and delivered continuous pipeline walking monitoring systems for TotalEnergies CLOV3 in Angola.

The system supports a "wait and see" integrity strategy by measuring pipeline movement before committing to mitigation. The CLOV3 system is described in OMAE 2026 materials as a world-first continuous pipeline walking monitoring system.

The design delivers 10 mm resolution, 16-year battery life and 1,500 m depth rating.

An uprated design rated to 3000m, with 1.25mm resolution and up to 30 year battery life is available.

Subsea Wireless 2.0 — magnetic communications, edge processing and cloud backhaul

The Subsea Wireless 2.0 programme validated key Lattice building blocks: low-power edge processing, wireless information transfer through water and through the water-air boundary, SEM integration, UAV backhaul and Azure cloud interface.

Houston and Edinburgh demonstrations showed fatigue information transferred to Azure through UAV / LoRaWAN backhaul, with live information viewed through a QR-linked interface.

ASEC — fixed-bottom cable monitoring 

ASEC validated key subsystems for fixed-bottom cable monitoring.

The programme covered Lattice FMS attachment, ROV deployment, cable fatigue measurement, E-Field CP mapping, magnetic communications, UAV harvest and end-to-end cloud automation.

ASEC provides technical evidence for Lattice MARS, but it is not itself a completed Lattice MARS deployment

Lattice E-Field — corrosion / CP monitoring

Lattice E-Field has been integrated with Fugro Blue Eclipse USV and Blue Amp ROV for autonomous corrosion / CP survey work.

Bergen sea trials have been completed. Installation, diagnostics and information recovery have been demonstrated. Qualification with TotalEnergies / Fugro is ongoing.

Lattice MARS pilot: Floating Energy Autonomous Operations (AMBES JIP) / Kincardine — floating wind

AMBES JIP pilot is the planned next step for floating offshore wind.

The programme is intended to extend Lattice monitoring to dynamic cable fatigue, mooring fatigue, corrosion, metocean, underwater noise, biodiversity and autonomous operations enabling live digital twin.

Field deployment is planned at Kincardine Floating Offshore Wind in 2027.
