Support-vessel dependence
Conventional survey and inspection campaigns can become tied to vessel availability, mobilisation windows, and the cost of keeping assets on station.
Andrasta Marine
Redefining what is possible offshore
Andrasta Marine develops hydrogen-powered autonomous marine vessels for persistent offshore survey, inspection, and environmental evidence-gathering without continuous dependence on support vessels.

Vessel OEM for persistent offshore survey
Andrasta Marine integrates commercial-off-the-shelf and bespoke marine, hydrogen, sensing, autonomy, and payload systems into complete offshore products.
Andrasta Marine develops hydrogen-powered autonomous marine vessels for persistent offshore survey, inspection, and environmental evidence-gathering without continuous dependence on support vessels.
The operating problem
Useful offshore information is often limited by endurance, handling, recovery, replenishment, and support-vessel cost rather than by sensor capability alone.
Battery and handling limits
Battery systems are effective in shorter-duration roles, but larger form factors and repeated offshore redeployment create mass, charging, and wet/dry handling constraints.
Decision-quality data
Decommissioning and inspection decisions benefit from repeated observations over useful time windows, not only isolated campaign snapshots.
The Andrasta approach
Hydride-focused hydrogen-electric vessels, remote replenishment, waypoint mission logic, and modular payload families are combined to improve time-on-task and asset utilisation.
Our Solution
Waypoint missions, patrol patterns, linger modes, and recovery planning are structured around practical offshore survey and inspection workflows.
Explore Our Solution →Technology
The architecture is built around hydride-based hydrogen storage, low-pressure storage philosophy, quiet sensing, and patent pending remote refuelling IP.
Review Technology →Vessel form factors
AndraMini and Andra40 define vessel scale. Mission capability is then configured through payload and operating variants.
AndraMini
Smaller vessel form factor
AndraMini is the smaller Andrasta Marine vessel form factor, intended to support early demonstration, practical offshore survey workflows, payload integration, and near-term partner trials.
Andra40
Larger autonomous offshore form factor
Andra40 is the larger Andrasta Marine vessel form factor, under development around hydrogen-electric endurance, hydride replenishment, modular payloads, and practical offshore logistics.
Payload and mission families
The payload families are framed as practical mission packages, not unsupported final product claims.
AndraBeam
High-resolution acoustic sensing and inspection payload family for detailed subsea survey, inspection, and evidence-grade environmental observation.
AndraField
Environmental and field-sensing payload family, combining field measurements, sensor inputs, and fused mission data products.
AndraRise
Semi-submersible mission configuration for camera-based observation above the waterline while retaining a low-profile marine operating mode.
AndraKeep
Low-disturbance station-keeping concept using a bio-inspired gripping or holding interface to reduce continuous propulsion demand during persistent monitoring.
Lead commercial focus
The first target application is low-regret environmental survey during and after offshore decommissioning works.
Decommissioning environmental survey
Repeatable environmental data before, during, and after offshore works
Persistent autonomous survey can support baseline data, repeat transects, environmental observations, and post-works assurance without continuous dependence on support vessels.
