The “”: a of superlatives “We Build the Incredible”

The “Oasis of the Seas” is the new queen of the seas. Royal ’s new luxury liner is the largest cruise ship ever built and launched by a shipping company. The construction of the liner involved technical challenges on a scale hitherto unknown. Encouraged by their excellent experience with Bender technology, the ship owners once again opted for the reliable electrical solutions offered by the Gruenberg company for the construction of this amazing miracle of engineering.
