Abstract
A floating production unit is operable for production and storage of hydrocarbons. The production unit exhibits in operation movement properties rendering connection of one or more loose hanging risers () of suitable material possible. Such a unit comprises a hull () and a deck () in an upper end of the hull, the deck being equipped adequately in accordance with the intended application. The floating production unit is distinguished in that the hull () is configured to allow suspension of the riser () on at least one frame () arranged in a shaft/moonpool () in a center of the hull () wherein vertical movements of the hull () are minimized, and that the moonpool () of the unit surrounds and protects an upper part of the one or more risers () and fixed tubes for transfer of fluid to a processing facility of the production unit against external forces such as waves, ice and vessel collisions, in addition to corresponding protection during connection of the one or more risers () unto the at least one frame ().
