FLOATING OFFSHORE PLATFORM WITH EXTENSION PLATES ATTACHED TO PONTOONS TO REDUCE ITS HEAVING Russian patent published in 2017 - IPC B63B35/44 

FIELD: transportation.

SUBSTANCE: floating offshore platform comprises a floating hull that consists of at least three vertically extending columns and at least one pontoon. One pontoon is made with the possibility to be positioned at least partially below the surface of the water in which the offshore platform is located. The upper part of the platform is connected to at least one of the columns and is located vertically at a distance from at least one pontoon. Each extension plate is located at a height below the surface of the water in which the offshore platform is located during operation, forming an underwater water separation zone between the extension plates. Each extension plate has a first side fixedly attached to the pontoon, and at least one free peripheral side. The extension plates are designed to reduce the platform heaving by at least providing horizontal water separation, vertical water separation, or a combination thereof around the extension plates connected to the pontoon, while the platform is moving in water.

EFFECT: improved performance and reduced horizontal or vertical movement of a floating offshore platform.
