What we build
Replenishable autonomous platforms and mission-support systems for civil, security, and defence applications.
Company
A Scottish subsea systems company built for difficult water and disciplined scale.
Andrasta Marine controls the architecture connecting autonomous vehicles, hydrogen-electric energy, payloads, replenishment, manufacture and mission logistics.
Origins
Built from the North Atlantic outward.
Ruggedness is not a finishing specification. It is a consequence of understanding where a system must remain useful.
Founder and Technical Lead Rhodri Hawkins grew up in Shetland, where severe weather, cold water, remoteness, and long support chains turn maintainability and practical usefulness into immediate engineering concerns. Offshore work still carries substantial vessel, fuel, weather, cost, and environmental overhead where available technology forces repeated intervention. That experience shaped Andrasta's focus on robust systems that reduce avoidable offshore activity rather than merely perform well in controlled conditions.
Before moving into hydrogen systems, Rhodri worked as an engineer in the water sector, developing an early grounding in regulated infrastructure, environmental responsibility, and long-life assets. He subsequently spent more than five years making high-consequence technical decisions across regulated hydrogen and multi-energy projects.
In 2025, aged 26, he became the youngest person ever awarded Chartered Chemical Engineer status by IChemE. Andrasta Marine brings that career path together: North Atlantic operating reality, disciplined process engineering, and a whole-system approach to energy, logistics, payload, manufacture, and lifecycle.

How we work
A focused system-authority model: retain control of the platform architecture and integrate specialist capability through explicit partner, supplier, IP, and assurance boundaries.
Engineering in Edinburgh
Naval, firmware and software engineering experts collaborate at our Engineering Centre of Excellence in Edinburgh, progressing research and design alongside practical integration optimisations.
Scale-up model
From programme learning to repeat manufacture.
Scale is designed into the architecture rather than deferred to production. Manta closes physical, integration, and manufacturing risk quickly; AndraSound establishes the repeatable mission platform; and common energy, power, payload, autonomy, handling, and service interfaces carry validated modules and evidence between programmes.
Customer-specific capability is concentrated in configurable payload, software, and mission-system layers, limiting the need to redesign the underlying vehicle for each application.

Rhodri Hawkins
Chartered Chemical Engineer · CEng MIChemE
More than five years' experience in high-consequence system design and technical decision-making across regulated hydrogen and multi-energy projects.
I founded Andrasta Marine to develop persistent subsea systems around the complete mission: energy, payload, logistics and service life. Across the mission profiles studied and simulated, hydrogen has justified its integration where it creates additional system-level value.
Following design iteration, simulation and component testing, Manta is in physical development. We are preparing for independent validation and opening discussions with development partners, licensees, distributors and test operators.
Operating principles
Technical ambition is carried by disciplined delivery.
System authority mindset
Own the physical platform architecture, energy integration, marine packaging, interfaces, and the engineering evidence that connects them.
Partner where it is stronger
Integrate specialist autonomy, command-and-control, sensing, fabrication, test, and assurance capability through explicit technical and commercial boundaries.
Build knowledge through evidence
Use test data, configuration history, and mission feedback to improve the platform family and compound learning across the programme.
Governance + supplier readiness
Governance and customer qualification develop with the platform.
Responsible use, security, quality and supplier controls are being built alongside the engineering programme, not added after a customer asks for them.
Responsible use
Lawful end use, defined operating boundaries, accountable human decisions, and clear escalation for ethical or security concerns.
Secure delivery
Information and cyber security, export-control and sanctions review, controlled technology transfer, and proportionate customer due diligence.
Business integrity + supply chain
Anti-bribery, conflicts, counter-fraud, AML risk, modern-slavery risk, supplier conduct, and proportionate counterparty checks.
Engineering + lifecycle
Controlled requirements, hazards, configuration, testing and corrective action, alongside maintainability, reuse, operational disturbance, and end-of-life planning.
Qualification pathway
ISO 9001
Certification target — preparation in progressQuality, document and configuration control, supplier assurance, non-conformance, corrective action, and test evidence.
DEF STAN 05-138 Issue 4
CSMv4 readiness in developmentDeveloping cyber security controls against MOD Cyber Security Model v4 supplier expectations and customer-assigned Cyber Risk Profiles; readiness work does not imply certification or blanket compliance.
Procurement evidence pack
Approved-supplier evidence in progressCore policies, registers, supplier controls, due-diligence evidence, improvement planning, and customer-specific responses.
Customer and partner discussions can address the applicable quality, cyber, export, supply-chain, business-integrity and responsible-use requirements directly.
Discuss assuranceProgramme status
What is built, what is defined, and what comes next.
The platform family advances through physical development, pre-integration design and independent evidence.
Physical development
Manta
The first prototype was completed in Q2 2026, with first water trials planned for Q4 2026.
RD&D ongoing
AndraSound + AndraHold
Platform architecture and pre-integration design are defined while research, design, and development continue. AndraSound development considers integration with state-of-the-art sensing, navigation and communications equipment within the sector. Compatibility is assessed for each mission configuration.
Validation pathway
AndraCharge
The robotic replenishment system is planned to undergo independent testing as its controlled development programme advances.
Careers
The team grows as the programme earns it.
Andrasta Marine expects to recruit selectively across marine engineering, autonomy, energy systems, manufacturing, test and assurance as customer programmes mature.
No open roles are listed at present.
Future opportunities will be published here as testing, customer programmes, and production demand justify them. Specialist partners and suppliers can still introduce relevant capability through the contact route.
