What HonuWorx does

HonuWorx Ltd is a UK-based subsea robotics company, headquartered in Aberdeen and founded in June 2020 by Lee Wilson and Lucas Wissmann with the stated mission of replacing surface support vessels with underwater deployment platforms. The company's product architecture centres on two integrated systems: Loggerhead, an all-electric, ultra-long-endurance autonomous submarine mothership designed to deploy and recover ROVs without surface vessels, and HonuNet, a cloud-edge communications and control platform that enables real-time video streaming, over-the-horizon robotics control, and geographically distributed team collaboration. A third core element is the compact inspection-class VALOR ROV (from Rovtech Solutions) which is outfitted with sensors and tools and operated 'over the horizon' from onshore control rooms. The technology was validated in a December 2023 world-first demonstration off Vancouver, in which an ROV was deployed from an autonomous mothership controlled from shore via the cloud.

The company sells and partners across three verticals: oil and gas (with named partners Shell and TotalEnergies via the Net Zero Technology Centre), offshore wind (construction support, cable and foundation inspection, O&M), and defence and security (critical undersea infrastructure monitoring, mine countermeasures, anti-submarine warfare, validated by selection for the NATO DIANA 2025 programme and a DIANA Rapid Adoption Service contract on behalf of Defence Research and Development Canada). Revenue is structured around subsea robotics services (subscription/recurring), HonuNet platform licensing (standalone service for conventional ROV operations), and R&D contract services (notably under NATO DIANA). Pricing is quote-based and bespoke; no public pricing is disclosed. Distribution is direct enterprise field sales to major operators in offshore energy and defence.

Commercially, HonuWorx remains pre-revenue at scale: the first commercial offshore tests are scheduled for 2027, with a target fleet of at least 10 Loggerhead units by 2030 and a longer-term ambition of 50 submersibles globally. The company is undergoing a £30 million investment programme as of March 2025, having previously closed a seven-figure round in September 2024 led by TRICAPITAL Angels and Scottish Enterprise, with UKI2S participating for a second time. Headcount is being scaled from 12 (October 2023) to a planned 36 over 2-3 years, anchored by senior leadership from ROVOP, Subsea 7, James Fisher Defence, and the Aberdeen subsea services cluster.

Core offering

HonuWorx provides subsea inspection, repair, and maintenance (IRM) services through its proprietary Loggerhead system, an all-electric unmanned autonomous submarine mothership that deploys ROVs without surface vessels. The HonuNet cloud-edge communications and control platform enables over-the-horizon control from onshore locations with real-time video streaming. The integrated platform delivers conventional subsea services at reduced cost with zero carbon emissions and zero offshore personnel, serving oil and gas operators, offshore wind developers, and defence organisations.

Product overview

HonuWorx operates as a subsea robotics company offering a unified platform architecture centered on two integrated products: Loggerhead (an all-electric autonomous submarine mothership deployment system) and HonuNet (the cloud-edge communications and control backbone). The system is designed to replace large diesel-powered surface support vessels with underwater deployment platforms, enabling subsea inspection, repair, and maintenance operations with zero carbon emissions and zero offshore personnel. The Loggerhead platform integrates a compact VALOR ROV that can be deployed and controlled 'over the horizon' from shore-based control rooms. HonuNet provides the communications infrastructure connecting the autonomous submersibles to onshore operators while enabling real-time collaboration across distributed teams. The technology serves multiple end markets including offshore wind, oil and gas, and defence sectors.

Products and services

• Loggerhead Flagship all-electric unmanned autonomous submarine mothership that deploys ROVs without surface vessels for subsea inspection, repair, and maintenance operations. The system connects to onshore operators via a surface buoy and cloud-based mission control, enabling remote subsea operations with zero carbon emissions and zero offshore personnel. Designed for enterprise customers in offshore wind, oil and gas, and defence sectors.
• HonuNet Cloud-edge communications and control platform serving as the communications backbone for the Loggerhead system. Offered as a standalone service for conventional offshore and ROV operations. Features mission digitalisation, robotics control, and distributed collaboration capabilities across geographically distributed teams, with optimised data flow for challenging bandwidth and over-the-horizon communications scenarios.
• VALOR ROV Compact inspection-class remotely operated vehicle manufactured by partner Rovtech Solutions Ltd and integrated into HonuWorx's platform architecture.

Emerging players

• Anduril Industries: US defense technology company building autonomous systems (air, sea, subsea) for defense and security applications. Comparable in the autonomous defense systems category where HonuWorx is pursuing undersea infrastructure protection; both companies target dual-use tech credibility and have pursued NATO/Allied defense relationships.
• Bedrock Ocean: US-based startup building autonomous unmanned surface vessels for ocean mapping and subsea survey work. Comparable as an emerging player applying autonomous, low-crew maritime robotics to subsea services — a similar disruption thesis to HonuWorx but focused on surface-vessel autonomy rather than submersible motherships.
• Cellula Robotics: Vancouver-based developer of autonomous underwater vehicles and subsea technology. Directly comparable as an AUV specialist and is also HonuWorx's technology partner (supplied the AUV mothership for the December 2023 world-first demonstration). Competes in the same autonomous subsea space.

Broad incumbents

• TechnipFMC: Global subsea services and equipment provider for the oil & gas industry, including subsea robotics and IRM services. Comparable as a potential customer/partner for subsea intervention technology and as a large incumbent in the same offshore markets HonuWorx targets.
• Kongsberg Maritime: Norwegian maritime technology company supplying autonomous underwater vehicles (Hugin AUVs), subsea robotics, and marine automation systems. Comparable in subsea robotics technology and defense/offshore market overlap, but operates as a broad maritime technology incumbent across many segments.
• Subsea 7: One of the world's largest subsea engineering, construction, and services companies for the offshore energy industry. Comparable target customer and operating environment (offshore oil & gas, offshore wind); HonuWorx's CEO Lee Wilson is a former Subsea 7 executive, reflecting the overlap in technical and commercial domain.
• Oceaneering International: Global subsea engineering and ROV services operator serving oil & gas, defense, and offshore markets. Comparable as the largest incumbent in subsea robotics services, but operates traditional surface-vessel-deployed ROVs. Represents the established commercial model HonuWorx seeks to disrupt with autonomous motherships.

Direct peers

• ROVOP: Aberdeen-headquartered ROV operator and one of the world's largest independent ROV service companies. Directly comparable as a subsea robotics services provider; notably, HonuWorx's chairman Steven Gray founded ROVOP. ROVOP represents the traditional crewed-vessel-deployed ROV model that HonuWorx aims to disrupt.
• SMD (Soil Machine Dynamics): UK-based manufacturer of subsea robotics including ROVs, trenchers, and crawlers used across offshore energy, defense, and scientific markets. Comparable as a subsea robotics manufacturer with overlapping customer base in offshore wind, oil & gas, and defense — the same verticals HonuWorx targets.
• Saab Seaeye: Manufacturer of electric underwater robotic vehicles including ROVs and AUVs. Comparable as a subsea robotics manufacturer with electric vehicle expertise that overlaps with HonuWorx's all-electric architecture. Operates as a broader subsea technology provider across defense and commercial markets.
