Oil and gas drilling


In oil and gas drilling, the splash zone presents issues like corrosion from fluctuating wet and dry conditions, biofouling, and difficult access due to waves and tides. These factors require innovative solutions, advanced technology, and strict safety protocols. OceanTech’s remotely operated robotic solutions perform splash zone operations beyond the capabilities of divers and ROVs. Leveraging our field-proven technology alongside advanced rope access and lifting methods simplifies these operations by reducing costs, enhancing safety, and minimising environmental impact.

Our services


OceanTech performs cleaning, inspections, modifications, and repair work in the splash zone. Our robotic solutions are unaffected by waves and currents, operate efficiently in confined spaces, and can fulfil any maintenance need. Services we provide in the oil and gas drilling sector include:

  • Anode installations
  • Caisson inspections, repairs, and replacements
  • Conductor pipe inspections and repairs
  • Clamp installations and removals
  • Fairlead repairs and replacements
  • Guide and bracket modifications
  • I&J tube installations
  • Riser inspections, repairs, and replacements
  • Riser protection net (RPN) repairs and replacements


We bring extensive and diverse experience, having completed over 70 projects across 50 installations globally.

Modularity in design


Our modular approach, along with our technology's adaptability to diverse materials, geometries, and surface conditions, enables our access robots and tools to connect to any offshore asset or structure, including:

  • Access platforms and boat landings
  • Bracings and cross-bracings
  • Conductor pipes
  • Drillships
  • Jack-up rigs
  • Platform legs and jackets
  • Riser systems
  • Semi-submersible drilling rigs

Why choose us


Cost savings

We offer significant cost savings by eliminating the need for divers, ROVs, or support vessels. Our robotic solutions reduce waiting times for weather windows, minimize downtime, guarantee predictable timelines for complex projects, and offer lower daily rates than other solutions.

Enhanced safety

Our robots and tools are operated from the topside, enabling unmanned operations near structures in confined spaces. This significantly enhances operational safety. We have achieved over 200,000 incident-free offshore work hours, demonstrating the reliability and effectiveness of our technology.

Reduced environmental impact

Our robots utilise existing infrastructure, allowing us to perform operations without the support vessels typically needed for divers and ROVs. This approach cuts emissions and lowers the risk of oil spills. Additionally, our ability to operate regardless of weather conditions helps decrease delays and further diminishes your environmental footprint.
