Hydride-focused hydrogen-electric architecture
The vessel, powertrain, handling philosophy, and replenishment chain are designed around hydride-based hydrogen storage from the start.
Technology architecture
Andrasta Marine combines vessel design, hydrogen-electric power, hydride storage, mission autonomy, remote replenishment, and modular payloads into a complete offshore product architecture.
Remote replenishment concept
Andrasta Marine owns IP for a droppable refuelling robot, with patent pending protection. Further validation is required before operational deployment.
Waypoint mission logic
Mission concepts include repeatable survey routes, patrol patterns, linger modes, recovery planning, and remote monitoring.
Quiet sensing platform
Minimal moving parts, low bubble generation, low electrical signature, and polymer hull design intent support improved acoustic and environmental data quality.
Low-pressure storage philosophy
Low-pressure hydride storage is intended to improve the relationship between endurance, handling mass, shock tolerance, and operational flexibility.
Modular mission payloads
Payload families are structured around acoustic inspection, environmental field sensing, above-water observation, and station-keeping workflows.
Civil demonstration pathway
The first commercial focus is low-regret environmental survey during and after offshore decommissioning works.
Hydride-focused by design
The differentiator is not simply adding hydrogen to an AUV. The vessel, powertrain, handling approach, and replenishment chain are designed around hydride-based hydrogen storage from the start.
Low-pressure storage philosophy
The public design intent is to use low-pressure hydride storage to improve practical handling, shock tolerance, and operational flexibility without publishing unvalidated performance numbers.
Ruggedised hydrogen-electric powertrain
Hydrogen-electric propulsion is framed around endurance, quiet operation, and useful offshore utilisation rather than unsupported range or depth claims.
Remote replenishment pathway
Andrasta Marine owns IP for a droppable refuelling robot, with patent pending protection. The concept has demonstrated principle-level functionality and requires further validation before operational deployment.
Autonomy and mission logic
Autonomy is presented conservatively: repeatable mission execution, remote monitoring, patrol and linger behaviours, and recovery planning. No autonomy figures are published.
Waypoint-based survey
Mission plans can be structured around repeatable survey routes, patrol patterns, station-keeping windows, and return or recovery logic for practical offshore workflows.
Commercially deployed autonomy features
The operating concept can integrate commercially deployed vessel autonomy software and features where appropriate, without claiming unsupported AI or fully autonomous decision-making capability.
Quiet sensing platform
The vessel architecture is intended to support better data quality by reducing avoidable self-noise and operational disturbance.
Minimal moving parts
A quiet operating profile supports environmental survey and acoustic inspection workflows.
Low bubble generation
Reduced disturbance is useful where observation quality matters over repeated mission windows.
Polymer hull design intent
A low electrical and acoustic signature is part of the wider sensing-quality proposition.
Higher-quality observations
The objective is decision-useful information over longer operating windows, not isolated campaign snapshots.
Payload and mission families
Payload families define practical mission packages while detailed performance and maturity data remain publication pending.
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.
