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.
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.
Skilled personnel and collaborative approach key to successful Riser Protection Net (RPN) replacement
– The Riser Protection Net (RPN) replacement has enabled Equinor to continue its Heidrun operations without costly disruptions, Ståle Karlsen, Project Manager at OceanTech, said.
Fairlead replacements for Equinor in the North Sea
In 2019, Equinor hired OceanTech to replace riser protection net fairleads at the Snorre A platform in the North Sea. The project has enabled Equinor to continue production without costly disruptions.
A caisson replacement job well performed
As more and more platforms on the Norwegian continental shelf are reaching their design life, installation components are starting to show wear and tear caused by the ravages of time existing in a harsh offshore environment. An example of this is damages caused by corrosion. Salt, water, air, and rough mechanical impact on metal are all ingredients in a corrosive meal.
Successful riser guard replacements at the Tyra field
Successful riser guard replacements require careful planning and a customised methodology for cutting, rigging, and lifting that addresses the project’s unique nature.
