Oil and gas production

Harsh environmental conditions, difficult access, safety risks, and limited operating windows pose challenges for maintenance work in the splash zone. Effectively addressing these demands advanced technology and specialised expertise to ensure operations are safe, efficient, and in compliance with regulatory standards. 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 production sector include:

Anode installations
Caisson inspections, repairs, and replacements
Clamp installations and removals
Cutting and removal of guides, braces, and brackets
Fairlead repairs and replacements
General structural inspections
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:

Concrete gravity platforms
Floating production storage and offloading units (FPSOs)
Jacket structures
Jack-up rigs
Semi-submersible platforms
Spar platforms
Tension leg platforms (TLPs)

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.
