Our Solution

A model designed to move offshore inspection and awareness from high-cost episodic operations toward persistent, flexible autonomy.

Current constraints

• Conventional support fleets and boat-deployed operations are operational-expenditure heavy.
• Many operations remain dependent on mother systems for deployment and sustainment.
• Subsurface systems are often tethered or battery-based, requiring frequent deck recovery for charging.
• This reduces time on task, limits utilisation, and increases operational disturbance and emissions intensity.

Andrasta operational approach

• Route-following missions with waypoint return, home-port logic, and configurable autonomy.
• Fuel dropped along the operational path and in situ via low-cost marinized fuelling robots.
• Deployment flexibility: helicopter, transport aircraft, and conventional marine methods.
• Operational emphasis on time-on-task, utilisation, flexibility, and reduced emissions intensity.

Design principles

System architecture is framed for manufacturability, operational realism, and low-disturbance mission continuity.

Designed for automated and remote operation from day 1.

Design-for-manufacture architecture for credible scale-out.

Low-cost potential despite hydrogen and light air/marine deployment architecture.

Rugged hydrogen fuel-cell plus battery powertrain approach.

Operation above or below water within the initial design envelope.

Persistent, low-disturbance measurement and maritime awareness.
