摘要
An actuating device (23) for a lay ramp (6) of a vessel (1) for laying underwater pipelines “(2) has a runner (28), and a carriage (29) connected to the lay ramp (6) and which runs along the runner (28) to lift and lower the lay ramp (6); the runner (28) being defined by a first, a second, and a third portion (31, 32, 33), of which the first and third portion (31, 33) are out of line with respect to each other, and the second portion (32) is mounted on a movable assembly (37) to selectively align the second portion (32) with the first and third portion (31, 33).
