Holland Shipyards Group has sealed its first contract with the Dutch Ministry of Defence.
The yard will construct two advanced floating training platforms, Uhlenbeck and Thetis, designed to support a wide range of maritime training operations for defence personnel. The contract also includes a 15-year maintenance period.
Both Uhlenbeck and Thetis are concrete structures built on pontoons and will be moored in Den Helder.
The Uhlenbeck platform (60 x 13.8 m) is tailored to provide operational dive training. It features:
• A robust concrete pontoon with technical installations and storage below deck
• A working deck with two knuckle-boom cranes for boat handling and lifting operations
• Boat storage and maintenance areas, including a workshop, protosorb room and mezzanine
• Instructional spaces including decompression and assembly rooms.
The larger Thetis platform (64 x 16 m) offers an extensive training environment across five decks, including:
• Changing rooms and gear storage for diving units
• Facilities for rinsing and drying dive equipment
• Control room and briefing areas for mission simulations
• Training setups for maritime boarding, underwater approaches, helicopter hoisting and fast-roping
• Direct connection to the Uhlenbeck platform for integrated operations.
This project team includes De Vries Werkendam, DWT Group, DMI-KBW, Antea Group and Royal Haskoning BV.
