蛇形？！充满智慧的新一代水下机器人

Kongsberg Maritime and Statoil have signed an agreement with Eelume, a NTNU spin-off company, to accelerate new technology that aims to significantly reduce costs related to subsea inspection, maintenance and repair operations.

NTNU and Sintef have conducted research on snake robotics for more than 10 years. Eelume is now developing a disruptive solution for underwater inspection and maintenance in the form of a swimming robot.

The idea is to let these robots do inspection and light intervention jobs on the seabed, reducing the use of large and expensive vessels. With its snake-like form, the slender and flexible body of the Eelume robot provides access to confined areas that are difficult to access with existing technology.

“Eelume is a good example of how new technology and innovation contributes to cost reduction. Instead of using large and expensive vessels for small jobs, we now introduce a flexible robot acting as a self going janitor on the seabed. To support smaller companies in bringing new technology to the market is an important part of our research portfolio,” said Statoil’ s Chief technology officer Elisabeth Birkeland Kvalheim.

Eelume robots will be permanently installed on the seabed and will perform planned and on-demand inspections and interventions.

The solution can be installed on both existing and new fields where typical jobs include; visual inspection, cleaning, and adjusting valves and chokes. These jobs account for a large part of the total subsea inspection and intervention spend.

“This partnership offers the chance to bring radical technology to the market, not just in what the Eelume robot can do, but how it does it,” said Bjørn Jalving, Executive Vice President Subsea Division at Kongsberg Maritime. “It is a new tool that will enable operators to realize large scale cost savings by introducing new ways of conducting routine tasks and helping to prevent unscheduled shutdowns by reacting instantly when required.”

The strength of the collaboration lies in the unique contributions from each of the parties. Eelume is founded by top academics from NTNU, Kongsberg Maritime brings in 25 years of experience and technology development within marine robotics and Statoil provides access to real installations for testing and qualification.

“With our unique expertise in the field of snake robotics Eelume is the first company in the world to bring these amazing robots into an industrial setting,” said Pål Liljebäck, CTO Eelume. “Now we take the step from academia and into the commercial world to secure our place in the new and exciting subsea intervention landscape.”

“This is a perfect example of how NTNU AMOS can contribute to bringing research based innovations into the market place through new spin-off companies and cooperation with leading industry players. Eelume is already the 5th spin-off company from researchers at NTNU AMOS and the third since 2013. SFF NTNU AMOS is strongly supported by the NTNU management, the Norwegian Research Council, Statoil, DNV GL and SINTEF Group,” said Asgeir J. Sørensen, Director, NTNU AMOS, Centre for Autonomous Marine Operations and Systems.

“As the main shareholder and responsible for business development in the company we think this is a perfect match for effectively introducing a new innovation based on NTNU inventions and competence into the market place,” said Anders Aune, Head of TechTrans, NTNU Technology Transfer AS. “The support from Innovation Norway and the FORNY program in the Norwegian Research Council has been crucial to reach this milestone.”

Eelume

Eelume is a disruptive technology for inspection, maintenance and repair operations for the subsea related industries. Our resident solution has intervention vehicles standing by on-site, allowing for both planned inspection cycles, on-demand operational inspection, and quick response intervention planning and execution.

Subsea costs have tripled

As existing subsea infrastructure is ageing, the demand for maintenance will increase. At the same time new installations are more complex due to increased depth and more challenging reservoirs.

Subsea costs have tripled since 2005.

IMR is a primary cost driver

Surface vessel-supported ROV operations for inspection, maintenance and repair (IMR) are time consuming and expensive, mainly driven by vessel cost. Eelume’s resident solution helps customers improve their maintenance performance and even accelerate production by reducing the number of vessel days.

Superior accessibility and intervention combined

The slender and flexible body of the Eelume vehicle provides access to confined areas making it the most efficient intervention tool for subsea IMR.
