What RotoTech does
RotoTech (Rototech Pte Ltd) is a Singapore-based robotics company specializing in robotic inspection, repair, and maintenance (IRM) for offshore industrial assets. Founded in 2021 by Simon Hartog in partnership with AI and Robotics Ventures (ARV), a subsidiary of Thailand's national oil and gas operator PTTEP, RotoTech develops robotic systems that perform hazardous inspection and maintenance tasks on offshore structures including jackets, risers, and other fixed assets. In August 2024, the company was acquired by Sonomatic Limited, a UK-headquartered non-destructive testing and inspection services provider, integrating RotoTech into a larger NDT platform with established UK and Australia distribution.
The company's product portfolio includes the Roto Climber family (MK1, MK2, and MK1 Mini variants), the Wind Climber for offshore wind turbine towers, the Roto Crawler for confined-space inspection, and the Roto Piler for jetty piling applications. These systems are designed for operation in Zone 2 hazardous-area environments and hold patents on key mechanical technologies, including the Clamp Passing Module filed in January 2024. RotoTech has positioned its offering as a cost-effective alternative to conventional rope-access inspection and maintenance methods, with operations reportedly priced at approximately 6.3x lower than traditional approaches — implying per-operation pricing in the $5.8k–$6.3k range.
RotoTech primarily serves offshore oil and gas operators, with named customers including PTTEP, Brunei Shell Petroleum, ADNOC, DPC, and PETRONAS. The company received PETRONAS Technology Approval in June 2025, representing a key regulatory milestone for deployment in Malaysian waters. The business model is service-based, with RotoTech deploying its robotic systems and personnel to client offshore sites. The company has also extended into the offshore wind vertical through the Wind Climber product, partially diversifying revenue away from pure oil and gas exposure. Early-stage development was supported through an April 2021 MOU with Olympus Singapore for NDT collaboration, and the company joined the SPRINT Robotics Collaborative in May 2022, signaling alignment with industry standards bodies.

RotoTech product offering
Product offeringCore offering
RotoTech designs, builds and deploys proprietary robotic systems for the cleaning, inspection and repair of offshore oil & gas platforms, subsea pipelines, jetty piles and wind turbine towers. Its six robotic devices operate from platform deck level down to 200–300 meters below sea level, eliminating the need for vessels and divers while delivering 5.8x to 6.3x cost reduction versus traditional inspection methods.
Product overview
RotoTech offers a portfolio of robotic cleaning, inspection, and repair devices for offshore oil and gas platforms, pipelines, jetty piles and wind turbines. The product line consists of five core robotic systems in production: the Roto Climber® MK 1 (lightweight inspection device), Roto Climber® MK 2 (multi-function maintenance platform), Roto Climber® MK 1 Mini (compact version for smaller pipes), Wind Climber® (for wind turbine towers), Roto Crawler® (for seabed pipelines), and Roto Piler (for jetty pilings). These modular devices can be equipped with attachable modules including the Clamp Passing Module for navigating clamped structures, and specialized wrapping systems. Technologies operate from above water through the splash zone to depths of 200-300+ meters below sea level.

Oceaneering operates one of the world's largest ROV fleets and serves the same oil & gas and offshore wind customers with bundled inspection and intervention solutions. Comparable in end-market and customer base; broader in scope.
Emerging players
- Hydromea: Swiss-based developer of underwater autonomous mini-robots and inspection systems for confined-space and submerged asset inspection. Emerging competitor in the subsea robotics NDT/inspection space with comparable miniaturization and cost-reduction value proposition.
- Planys Technologies: India-based provider of underwater robotic inspection services for ports, dams, pipelines and offshore infrastructure. Emerging player in underwater inspection robotics with overlapping use cases in pipeline, pile, and riser inspection.
Direct peers
- Vertech: Another CWL Group sister company delivering rope-access and robotic inspection services to offshore and industrial clients. Direct overlap in non-destructive testing, inspection, and asset integrity services to the same operator customer base.
- Innospection: Sister company within the CWL Group providing advanced NDT inspection technologies for offshore and industrial assets. Overlaps with RotoTech in climbing/inspection robotics for tanks, vessels and piping — closely comparable in technology category and customer base.
- Sonomatic Limited: Parent company and now primary delivery arm for RotoTech. Sonomatic provides robotic and conventional NDT inspection services for offshore assets, including risers, conductors and caissons — the same assets Roto Climber targets. Direct functional overlap in IRM service delivery.
Others
- Stoneage (StoneAge Waterblast Tools): Supplier of high-pressure waterblast tools used in industrial and offshore cleaning, including RotoTech's trusted-by partner. Adjacent in cleaning-tool technology for the same underwater cleaning applications RotoTech addresses.
