A tanker (1) is converted to a floating production ship by a vertical opening (1) being cut out in the hull (1) and a cassette-like plate structure (7) inserted in the opening. The cassette (7) is composed of plate elements (12, 13) which are designed to fit and connect with the cut elements in the hull's opening. The cassette (7) will thereby form part of the ship's hull strength. The cassette has a vertical shaft (8) for mounting a turret (14) in/near the ship's bottom area. The turret (14) is wet-mounted in the shaft.
