Now, engineers and professionals with an interest in splash zone challenges can stay updated on news, articles and events by OceanTech.
Repair work in the splash zone
Repairing offshore structures in the splash zone is a complex task due to various environmental, technical, and logistical issues. 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.

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.
Subsea clamp design and installation: Tools and techniques
OceanTech's engineers boast a wealth of expertise in subsea clamp design and installations. Here is an insight into our work processes, tools, and techniques.
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.
Anode installation at the Dudgeon Offshore Wind Farm
An OceanTech engineering team developed rigging and lifting methods for a successful installation of 725 sacrificial anodes across 67 assets at the Dudgeon Offshore Wind Farm. This helps prevent internal galvanic corrosion inside transition pieces, saving Equinor time and money in asset maintenance.
