The project
For a cutting-edge offshore project, Hydrauvision partnered with Derinsu Underwater Engineering, a global provider of marine and geophysical research solutions, specializing in hydrography, geotechnics, and subsea environmental monitoring. The challenge: to design and deliver an advanced rotary active heave compensation system capable of accurately handling highly sensitive research equipment in the deep ocean.
Our approach
Hydrauvision engineered a powerful winch installation, based on our proven HP200E powerpack range and a Rotary Active Heave Compensation (RAHC) concept, featuring an impressive range of functionalities. The system integrates high pulling force with intelligent control to ensure accurate, stable deployment, even in highly dynamic subsea environments.
Key specifications
- Pulling capacity: 15 tonnes
- 5,700-meter Dyneema® cable
- Speed: up to 100 m/min for both payout and retrieval
- Automatic spooling device for smooth, high-speed cable winding and unwinding
- Full rotary active heave compensation for real-time motion control
The system enables the controlled lowering of a highly sensitive scientific instrument designed to detect neutrinos; subatomic particles essential to fundamental physics research.
From Concept to Commissioning
This project showcases Hydrauvision’s strength in managing complex, multidisciplinary challenges. With no existing design as a starting point, Hydrauvision demonstrated its full cross-functional capabilities. Hydraulic and mechanical design, electrical engineering, and control software were all developed in-house. From concept and design to testing and commissioning on site.
Engineered for the Future
This collaboration highlights our commitment to delivering integrated solutions for emerging sectors like deep-sea exploration and advanced oceanographic research. By combining innovation, precision, and reliability, Hydrauvision continues to push the boundaries of offshore equipment technology.
