OceanTech has achieved ISO 45001 certification and has been recertified to ISO 9001 and ISO 14001. Together, these certifications confirm that OceanTech’s management systems meet internationally recognised standards for quality, environmental responsibility and occupational health and safety – and that they are consistently applied across our engineering, project management and offshore operations.

OceanTech was founded in 2017, but several members of the team have spent more than two decades working in the splash zone across inspection, modification and repair projects. Across hundreds of operations, a clear pattern has emerged: the best solutions are developed when operators involve OceanTech early and maintain continuity over time.

Since 2001, OceanTech has collaborated with Equinor to push the boundaries of what is possible in the splash zone, developing innovative approaches to problems no one else has taken on.

The splash zone creates a uniquely hostile environment for inspection. Breaking waves, surge, aeration and rapidly changing visibility conspire against stability and repeatability. In this setting, operators typically choose between divers, ROVs, and access robots that clamp or track along the structure. Each approach brings distinct safety, uptime, environmental and data-quality implications.

Cleaning in the splash zone may turn routine tasks into high-risk work. Surge, spray and aerated water make sustained contact difficult while raising exposure for people and equipment. Teams typically pick from divers, ROVs or access robots—each with a distinct profile for safety, workable weather windows, emissions and documentation quality.

OceanTech has opened a new office in Perth, Western Australia, in partnership with Pulse Technology, strengthening support for operators across the state’s offshore energy sector and beyond.

Whether it’s inspection, maintenance, repair, or installation, the success of a splash zone project depends heavily on the expertise and reliability of your chosen partner. Selecting the wrong partner can lead to delays, cost overruns, safety incidents, and compromised asset integrity. Choosing the right one, on the other hand, ensures efficiency, safety, and long-term value. Here are 5 essential questions to ask before awarding your next splash zone contract.

For Tore Prytz, Senior Engineer Marine Operations at OceanTech, engineering isn’t just a job—it’s a lifestyle rooted in creativity, craftsmanship, and a passion for building.

At OceanTech, we are problem solvers tackling some of the most complex challenges in the offshore industry. For those who thrive on pushing the boundaries of what is possible, this is the place to be, says Peter Sommerseth Jaer, Engineer Marine Operations and Project Manager at OceanTech.

The successful execution of riser protection net replacements hinges on thorough planning and rigorous onshore testing. But what are the key factors to consider during the feasibility phase?

The 2025 FIS Nordic World Ski Championships in Trondheim strive to set a new standard as the most sustainable event in Nordic sports history. OceanTech will be there alongside Equinor and local players who share our commitment to smarter, more sustainable solutions.

OceanTech’s custom solutions may require three to six months of onshore preparations. However, involving us in the planning phase ensures the solution is optimised from the outset, enabling seamless offshore execution, significant cost savings, and a shorter overall project timeline.

Offshore divers and ROVs could be highly effective in performing IMR operations at significant depths. However, in the challenging splash zone, alternative solutions are often required to ensure safety, efficiency, and in some cases, enable operations that otherwise would be unfeasible.

OceanTech provides inspection solutions tailored to meet the unique demands of the splash zone environment. Our alternating current field measurement (ACFM) capabilities enable offshore operators to efficiently and safely detect surface cracks and assess structural integrity.

To uphold health, safety, and environmental (HSE) regulatory standards across our operations worldwide, we employ a rigorous compliance strategy. Here’s how we have achieved over 200,000 incident-free work hours offshore.

The Diverless Riser Inspection Tool (D-RIT) enables cleaning and inspections of flexible risers, including riser balconies, bellmouths and bend stiffeners, without using ROVs, divers, or support vessels.

Our Subsea Test Centre is ideally suited for testing subsea equipment, fish farming cages, and wind turbine components. With direct quay access, it also handles light shipyard operations.

Specialist technology companies can contribute to maximising maintenance and classification while rigs remain in operation.

Testination Trondheim has been selected as a new Katapult node, solidifying Trondheim’s position as Norway’s leading technology hub. The node is expected to attract knowledge-based jobs to Trondheim and will offer marine companies access to cutting-edge test facilities. “A unique ecosystem is emerging in Nyhavna, where leading marine research institutions and universities collaborate with major industrial players and scaleups. With the new node, it will become easier to test and validate new technologies at reduced risk,” OceanTech CEO Bernt Schjetne says. The node will serve as a national centre for testing, developing, and implementing autonomous technologies for the ocean industries. It is part of DigiCat under the Norwegian Katapult program.

Managing personnel-on-board (POB) during offshore maintenance can be challenging. We address this issue with minimal POB and lightweight equipment. Leveraging our extensive experience in coordinating complex projects, we ensure efficient, safe, and cost-effective execution offshore.

Since 2019, OceanTech has maintained a valuable collaboration with Vertikal Service. CEO Bernt Schjetne highlights the importance of cultivating long-term partnerships, engaging subcontractors early in the planning process, and strongly emphasising joint training onshore. These practices are vital for attaining optimal efficiency and safety in splash zone projects.

The harsh conditions in the splash zone make…

For many years now, oil and gas operators and service companies have been performing routine subsea interventions at depths of hundreds of meters and well interventions at depths of thousands of meters.

1. Are support vessels required during splash…

The splash zone is frequently defined as a non-accessible area and poses significant challenges to operations in offshore wind, oil and gas, fish farming, and transport infrastructure. But what exactly is the splash zone? And what are the challenges in splash zone operations?

ROVs may perform better at greater depths, but in the splash zone, OceanTech’s robotic solutions offer a wide range of benefits for businesses performing underwater cleaning, inspections, and maintenance work.

OceanTech’s robotic solutions for splash zone operations do not require the use of any offshore divers. This provides several benefits to your business, including improved safety, significant cost savings, and reduced carbon emissions.

– The Riser Protection Net (RPN) replacement has enabled Equinor to continue its Heidrun operations without costly disruptions, Ståle Karlsen, Project Manager at OceanTech, said.

Could OceanTech Innovation AS be Trondheim’s best kept secret?

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.

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.

Virtually any industry carrying out maintenance work, inspections, cleaning, or modifications to underwater structures in the splash zone, can use OceanTech’s innovative robotic solutions.

OceanTech’s remotely operated Clamp Access Tool (CAT) with built-in cleaning functions offers an array of benefits, including significant time savings, improved safety, and riser and conductor cleaning according to specific inspection needs.

Successful riser guard replacements require careful planning and a customised methodology for cutting, rigging, and lifting that addresses the project’s unique nature.

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.

By using OceanTech’s eddy current welding inspection robot in a life extension project, ConocoPhillips Skandinavia realised a cost saving of $1.9 million compared to conventional solutions.
