OCEAN INFORMATION SERVICES
Create a captivating first impression with a full-width video background that instantly draws visitors into your story. Use a high-quality, looping video that reflects your brand, product, or atmosphere, while keeping the foreground content clear and easy to read. We recommend subtle motion, muted colors, and no distracting audio so your message stays in focus. Combine the video with a concise headline, short supporting text, and a clear call-to-action button to guide users toward the next step on your site.
From Periodic Inspection to Continuous Intelligence
Persistent sensing and wireless water to air data transfer reduce inspection cost, risk and emissions

LEGACY MODEL
- Decisions based on risk assumptions
- Periodic campaigns with highly carbon intensive crewed vessels
- No asset visibility (blind spots) between inspections
- Personnel repeatedly exposed to offshore hazards
- High-cost routine mobilization
- No persistent security visibility

OIS MODEL
- Decisions based on live asset data
- Crews mobilised only when needed
- Continuous data feeds digital twins
- Sensors operate in hazardous zones
- OPEX reduction: 60–80%
- Low cost, persistent integrity monitoring across critical assets
Reduced Risk
Early detection of failure signals
Lower OPEX
Fewer vessel campaigns
Critical Infrastructure Security
Persistent monitoring of strategic seabed corridors
Lower Carbon
Fewer vessel campaigns enabled by wireless water-air data transfer
Markets
Fixed-bottom offshore wind
Monopiles, jackets, substations, export cables, inter-array cables, cable protection systems and touchdown zones.
Floating offshore wind
Floating structures, moorings, dynamic cables, lazy-wave sections, anchors and seabed interfaces.
FPSOs and floating production
Risers, moorings, umbilicals, pipelines, flowlines, slug behaviour, flow assurance and production-related dynamic response.
Environmental, coastal data-centre and thermal power infrastructure
Subsea power cables, optical cables, interconnectors, pipelines, ports, harbour approaches, cable landing zones and strategic seabed corridors.
Critical underwater infrastructure
Subsea power cables, optical cables, interconnectors, pipelines, ports, harbour approaches, cable landing zones and strategic seabed corridors.
Territorial-water security and defence
Island routes, naval approaches, port approaches, offshore energy areas, strategic corridors and wider monitored sea areas under sovereign authority.
Fixed-bottom Oil & Gas
Jackets, conductors, risers, caissons, pipelines, flowlines and subsea tie-ins in the North Sea, Gulf of Mexico and other mature offshore basins.
Monitoring requirements include fatigue, corrosion / CP performance, vibration, free spans, scour, structural response and flow-assurance issues where relevant.
Solving the Communication and Navigation Gap
Seawater breaks conventional connectivity and makes repeatable autonomous inspection difficult.

THE COMMUNICATION & NAVIGATION PROBLEM
Acoustics do not cross the water-air boundary effectively.
Conventional radio is rapidly attenuated underwater.
For navigation, acoustic beacons are power hungry and detectable.
THE OIS PATENTED MAGNETIC UPLINK
Low frequency magnetic signalling enables wireless water to air backhaul and short range subsea communication enabling 2 operating modes:
1. VERTICAL MODE
Sea-to-surface wireless data transmission: overcoming the air-water barrier
2. HORIZONTAL MODE
Magnetic reference nodes for AUV INS correction and repeat patrol
The foundation for Autonomous Subsea Operations at global scale
Solving the Battery and Data Economics Gap
Persistent subsea monitoring only works if the system can process data locally and transmit selectively.

THE BATTERY ECONOMY PROBLEM
Subsea sensors generate large volumes of data.
Transmitting it all drains battery life and breaks the economics.
THE OIS EDGE INTELLIGENCE
Raw data is processed on-device, so only decisión–relevant information is transmitted with up to 30 years of autonomy achieved
