Technical Concept
Overview
FEEDERDOCK is a fixed to fixed offshore installation method. A U-shape jack up main vessel remains permanently on site, while two feeder vessels shuttle components and operating material from port. Each feeder docks into the moonpool and jacks up together with the main vessel as one unit. This supports a continuous feedering process with reduced offshore transfer risk.
Operating Principle
Main vessel
- U-shape jack-up with moonpool
- Jacking-up as ONE unit
- Stays on construction site, installing
permanently - Installation assets supplied by feeders
- Operating material supplied by feeders
Feeder vessel
-
Two feeder vessels commuting between port and site
-
Feeder docking into the moonpool
- No component transfer at sea
-
Fixed-to-fixed installation method
-
Continuous feedering process

Future Proof Design
The FEEDERDOCK solution is designed to meet the demands of next-generation offshore wind turbines exceeding 25 MW, while remaining flexible across the full lifecycle of offshore assets. Its adaptable system supports not only installation but also operations & maintenance (O&M) and oil & gas decommissioning, making it a future-proof logistics concept for evolving energy markets.
