Based on its international experience on Jack-up Barge design and construction, POSEIDON brings a new concept for Marine Restaurants.

With its jacking system, POSEIDON Jack-up Restaurant provides a modern, confartable  and panaromic ambiance to the guests. This concept easily can rise up on its legs and this helps the concept to eleminate the negative impact of sea conditions and to have a panaromic view approximetaly 10 m above sea surface.

There is totally 1050 m2 closed area and the concept consists of 3 decks (each 350 m2 closed area). The net open area is 500 m2.

The 2nd deck is designed as a disco&music hall.

Guests may arrive at the barge either by hellicopter, or by boats.

The below deck will consist of a big galley, crew cabins, stores and tanks.

The total capacity of this concept is max 1000 guests.
