Technical Aspects

The primary feature of Brova Pearl is a floating double hull concrete structure – the floater.

On this Floater the final and complete structure is placed, as the floater will serve as the structural foundation and base.

The floater has an outer diameter of 108m, which is suitable for production in world’s widest drydock. Height from the bottom to the top of floater is determined based on the weight of topside (e.g. apartments, hotel, shopping centers etc.) in order to provide a safe distance from sea level to these facilities.

The floater is made of a double bottom- and double side concrete construction as an extreme safety measure to avoid flooding of areas such as car parks and technical rooms. It is worth noting that even the largest concrete structures in the North Sea submerged to 300m below the surface are single hull constructions only.

The walls are designed for a lifespan of several hundred years without encountering any damage or defects to the construction material (concrete and steel reinforcements) even during operation in high salinity sea water and tropical temperatures.

Floater’s outer side is provided with wave breakers and spray shields to minimize the impact of the worst possible incoming waves.

The bottom is adequately strengthened to allow the structure to rest on readily prepared seabed or, of course, to take the water pressure when moored in floating position. The bottom structure is designed with input from heavy transport vessel operators to ensure that the complete building can be transported without requiring special reinforcements to cargo deck of a selection of heavy transport vessels.

The total construction weight is kept within limits for transport by the world’s largest heavy transport vessels. All equipment and strongpoints for mooring and transport will be readily incorporated in the concrete structure.

There are no underwater installations, penetrations or connections which cannot be inspected and maintained from inside the floater or by divers.

A UNIVERSAL FLOATING STRUCTURE THAT CAN BE MOVED AND RELOCATED, INSTANTLY TRANSFORMING THE SKYLINE OF ANY CITY.
