Reduce risk and costs; extend asset life

 OIS fuses above- and below-water information to optimise asset life, reduce risk and minimise environmental footprint.

We deliver cable and structural fatigue monitoring, alongside environmental and cetacean monitoring, for fixed-bottom wind farms. Lattice MARS carries live information wirelessly through the water–air boundary into field-wide digital twins, supporting better inspection, maintenance and life-extension decisions.

AMBES JIP extends this to floating structures, dynamic cables and moorings.

The Stay-on-Mission JIP is qualifying AUV monitoring of extended array cables and interconnectors, combining persistent sensing with autonomous inspection to reduce dependence on vessel campaigns.




Understand the environment. See change sooner.

The marine environment changes between surveys. OIS provides long-term monitoring above and below water, helping customers understand changing conditions, assess environmental impact and manage their environmental footprint.

Lattice EMS combines sensors with local processing, storage and wireless information recovery. Each installation is configured for its monitoring task, with options including water quality, currents, waves and passive acoustics for cetacean and underwater-noise monitoring.

Lattice MARS delivers live environmental information through the water–air boundary for integration with above-water measurements, monitoring systems and digital twins. Lattice Neptune enables information recovery through mobile Lattice Gateways where fixed connectivity is impractical.

Our solutions support environmental regeneration of seagrass, oysters and mangroves,  ports and coastal infrastructure—providing persistent information to guide operations, environmental assessment and protection of marine habitats.





Reduce risk and cost. Extend asset life.

OIS integrates above- and below-water monitoring for offshore asset integrity, flow assurance and security—helping operators to reduce costs, optimise asset life and minimise environmental footprint.

Lattice devices monitor pipelines, risers, moorings and submerged hoses for fatigue, vibration, corrosion and operating conditions between inspections.

Lattice MARS carries live information through the water–air boundary into digital twins, supporting earlier detection of problems and better maintenance decisions.

Lattice Neptune enables information recovery by ROVs and AUVs. Our Stay-on-Mission JIP is qualifying autonomous recovery and navigation correction for extended pipeline monitoring, reducing vessel dependence.

Know what is happening beneath the surface.

Critical infrastructure needs security coverage above and below water. OIS brings persistent subsea sensing and autonomous patrols together to support protection of cables, pipelines, ports, naval approaches and territorial waters.

SeaWay Dome solutions combine seabed Lattice devices with fixed and mobile Lattice Gateways, tailored to each security requirement. Local processing turns acoustic, environmental and asset-condition measurements into information that helps customers identify changes and prioritise investigation.

Our Stay-on-Mission JIP is qualifying information exchange and navigation correction for sustained AUV operations—supporting wider monitoring coverage with less dependence on crewed vessel campaigns.



A new home for digital infrastructure. Beneath the surface.

Growing demand for AI compute calls for new approaches to infrastructure management. OIS designs and builds resilient subsea data-centre modules, bringing marine engineering and digital infrastructure together.

Our modular approach places computing hardware below water, with power, connectivity and handling facilities above. It enables customers to plan subsea infrastructure around their capacity, location and operational requirements—from individual modules to larger installations.
