The Harlingen-based shipyard, which specialises in refits, is now also able to overhaul or build new yachts up to 130 metres long and 30 metres wide.
Construction of the floating dock has already begun and the inauguration is scheduled for the end of the year.
The most recent refits include the 82.30 metre long "Secret" from Abeking & Rasmussen, the 68.15 metre long "Global" from Lürssen and the 62.13 metre long "Virginian" from Feadship.
