The Splash Zone Network
Now, engineers and professionals with an interest in splash zone challenges can stay updated on news, articles and events by OceanTech.
Inspections in the splash zone
Collecting accurate real-time data in the dynamic splash zone environment is challenging. Complex structures, wave impact, and corrosion make it difficult to interpret inspection results accurately. 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
Our robotic solutions offer a stable platform for deploying sensors, cameras, probes, and other inspection tools—tasks that would be challenging or impossible using divers and ROVs. Inspection services include visual and non-destructive testing (NDT) techniques tailored for the splash zone and underwater structures:
- Alternating current field measurements (ACFM)
- Close visual inspections
- Cathodic protection measurements
- General visual inspections
- Pulsed Eddy Current (PEC) thickness measurements
- Ultrasonic thickness measurements
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
- Boat landings
- Bracings and cross-bracings
- Concrete gravity platforms
- Conductor pipes
- Corrosion protection systems
- Drillships
- Floating production, storage and offloading units (FPSOs)
- Jacket structures
- Jack-up rigs
- Riser systems
- Semi-submersible platforms
- Semi-submersible drilling rigs
- Spar platforms
- Tension leg platforms (TLPs)
- Transition pieces
- Turbine monopile foundations
- Turbine jacket foundations
- Turbine towers
Why choose us
Cost savings
We offer cost savings by eliminating the need for divers, ROVs, or support vessels. Our robotic solutions reduce waiting times for weather windows, minimise downtime, guarantee predictable timelines for complex projects, and offer significantly lower daily rates compared to ROV operations.
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 use 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 decreases delays and reduces your environmental footprint.
How we work
OceanTech is a turnkey provider, managing all project interfaces to save our clients time and effort. Our integrated approach includes our unique Splash Zone Concept. In addition to our core solutions, we provide feasibility studies, design and engineering, planning and execution of intricate lifting operations, rental of ROV-tooling, and equipment testing at our Subsea Test Centre.
Our team is actively engaged in every project phase, from initial planning to implementation. We ensure each project is conducted safely, efficiently, and predictably with minimal handovers.
Customised solutions for all cleaning and inspection needs in the splash zone
Our ability to modify and tailor equipment, tools, and control systems to projects allows us to clean and inspect virtually any offshore structure in the splash zone.
