Do you Drive Purposeful Innovation?

About the Role

As a Senior Hydraulic Systems Engineer, you will lead the hydraulic engineering scope for subsea and topside hydraulic and pneumatic systems used in APL’s turret mooring systems. You will define hydraulic design bases, develop system drawings, optimize system performance, and support construction and commissioning activities. This role is central to ensuring safe, robust, and high-performing hydraulic solutions across complex offshore installations.

About the Company

NOV APL, located on Hisøy outside Arendal, is a part of NOV Marine & Construction and a global leader in advanced offshore loading and mooring technologies.
