Marine bioproduction facility

A marine bioproduction facility for farming of sessile marine organisms in a body of water is disclosed. The facility comprises an array of at least two production modules in contiguous geometrical relationship to each other, where each of the at least two production modules is adapted to be arranged within a vertical column with a predefined horizontal cross section and extending downwards from the water surface, where at least one of the at least two production modules comprises at least one growth surface for sessile marine organisms, and an upper part comprising at least one opening adapted to allow access to the vertical column. Further, a method for growth and harvesting of marine sessile organisms using the marine bioproduction facility is presented.
