Enabling multimodal AUV residency with wireless technology:

The Problem: Persistent Underwater Presence

AUV missions are limited by battery endurance and recovery cycles, creating gaps in underwater awareness and increasing operational risk for defence, security, and industrial users..

The Solution

Inductive subsea docking stations that let AUVs dock, recharge, exchange data, and stay resident without surfacing. Deployable under jetties, beneath buoys, or in mobile/towed configurations.

Why It’s Different

Works with any torpedo or flat AUV
Supports resident, buoy-mounted, and mobile/towed concepts of operation
200 W–2.5 kW inductive power, roadmap to 25 kW
1 to 10 Gbps agreageted
Proven subsea technology with world-record performance
3000 m rated, 15-year life API17 F and SWiG compliant
Integrated inductive positioning for reliable docking in low visibility

Powering the world’s longest-resident subsea drone

When Equinor and Saipem set out to prove that resident subsea drones could replace large parts of traditional IMR vessel campaigns, they needed one thing above all: a subsea “home base” that could deliver reliable power and data day after day, month after month.
That is exactly what Unplugged delivers.

Underwater Refuelling-in-Motion

No connectors. No surface recovery. Just continuous operation. AUV missions have been limited by the same constraint: sooner or later, they must surface. Surfacing exposes the vehicle, delays the mission, and requires a costly support vessel — and clam waters. Unplugged, together with partners in the ACCESS AUV program, has demonstrated a system that removes this limitation: A fully submerged, USV-towed docking station that allows AUVs to recharge and offload data while the system is in motion. This concept is the subsea equivalent of aerial refuelling — and it has now been proven at sea.

The Problem: Mechanical Slip Rings Limit Uptime

Traditional slip rings wear out, generate debris, require lubrication, and degrade electrically over time. In high-duty industrial environments—robotics, rotating machinery, automation cells, packaging lines, wind turbines, defence platforms—this leads to unplanned downtime, higher maintenance costs, and constraints on system design.

The Solution

Inductive Slip Rings that transfer power and data magnetically across an air gap.
No contacts, no friction, no wear. Designed for continuous rotation, high vibration, dust, chemicals, and wide temperature swings. The even work subsea

Why It’s Different

Contactless & wear-free – magnetic coupling eliminates brushes and mechanical interfaces.
High reliability in harsh environments – resistant to dust, oil, humidity, shock, vibration, and water.
Scalable power – from sensor-level watts to kilowatt industrial drives.
Data transfer – 1mbps to 100 mbps
Rotation – 0 to 5000 rpm
Maintenance-free – no lubrication, no replacement cycles, no performance drift.
Long service life – designed for years continuous operation.

Technology applied

Robotic hot tool swap in an (Ex) explosion hazardous zone

Robotic Drilling Systems (RDS) develops robot technology for fully unmanned drill floor operations. RDS was in a need of a tool interface which enabled the robot to hot swap tools autonomously in an Ex enviroment. The tool interface needed to support 360 degrees of continuous rotation while suppling the tool with power and a data communication link.
