Meet The Sea Cocoon

Floating hotel, restaurant, bar, bath facilities, public area and a park on the top foor.


Self contained energy production


Self contained energy production or even energy positive for heating and cooling based on proprietary technology and zero-emissions, Desalination plant for fresh water production.

Concrete is glued stone, and very strong.
As concrete is cast, it is moldable, to any shape.

Concrete structures may be designed for any purpose and the concrete material also. By varying the constituent materials one can obtain light concretes and heavy concretes, weak and strong. Concrete is exceptionally durable,
when designed and built properly. Brova floating

platforms have a life of more than 200 years. Strength increases with time.

North Sea concrete platforms are designed to resist impacts of tanker ships, at full speed. So is Brovas double hull is additional safety and makes the platform virtually unsinkable.

There are more than 3 million cubic meters of offshore concrete structures for the oil and gas industry in the world; Brovas partner Dr.techn.Olav Olsen has designed approximately 2/3 of them.

The Pantheon – a concrete structure, is almost 2000 years old


100% GREEN


All waste will be recycled on site. Brovas constructions have a state of the art process and program to recycle ALL waste

Water cleaning, food waste and sewage.

The leftovers from food processing and
restaurants plus the sewage is being
transported with vacuum to a composting
unit connected to a dewatering unit separating water and solids.
The solids are led direct into the composter which also is open for manually feeding of cardboards, papers, magazines, wood (clean), flowers, grass, garden waste etc.

The composter transforms the solids into a rich and powerful compost/fertilizer.

The weight and volume is minimized with minimum 80%. This compost will/can be used to fertilize all plants within the hotel, and the rest donated to local farmers for usage.

Topsides will be constructed using a mix of steel, aluminium, concrete and composite materials creating a lightweight and fireproof structure

Initial design is based on approximately 160 rooms and suites with a total square area of approximately 9000 m2 necessary to cater to a 5 star standard service.



Brova has all energy needs covered on site. The system is a combination of solar power and kinetic power plants. The construction is a so called energy active construction.

The system is 100 % emission-free: no CO2, no NOx The system is 100 % energy self-sufficient: require no inputs

Kinetic Power Plants (KPP) are pneumatic systems where kinetic energy is generated through a combination of buoyancy, gravity and cavitation. The system includes an exclusive generator, air compressor, and circuit controller. A series of lifting bodies attached to a gear system rises in a tank filled with water, and are injected with pressurized air to increase upthrust.

Microbubbles are injected at the downfall side, which increases the downfall speed of the bodies (Cavitation). The generator then works as a brake to keep the speed of the lifting bodies under control, such that the system can self-loop (keep itself running), while also producing excess energy for base load power production

Brovas partner KI-tech is involved in the whole process of construction and servicing of the modules.

Solar energy – many areas of the structure are covered by elegant Solar Hybrid Panels. Photovoltaic thermal hybrid solar collectors,
sometimes known as hybrid PV/T systems or
PVT, are systems that convert solar radiation

into thermal and electric energy. These systems combine a solar cell, which converts sunlight into electricity, with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module.

The capture of both electricity and heat allow these devices to have higher exergy and thus be more overall energy efficient then solar photovoltaic (PV) or solar thermal alone


Brovas desalination system produces drinking water from sea water based upon the reverse osmosis membrane technique.

The quality of the drinking water is continuously monitored, and will somewhat vary depending of quality (pollution) of input water.
