The invention provides an articulated extension ladder for ships. A first rotary articulated part comprises a base, a hydraulic cylinder, an upper ladder, a rotary shaft, a sleeve and a sliding bearing bush; a second rotary articulated part comprises a hydraulic cylinder, a rotary shaft, a thrust bearing bush, a rotary plate and a sleeve; a pitching articulated part comprises a parallel hydraulic cylinder, a hinged block, a pin shaft and a middle ladder; an extension articulated part comprises a hydraulic motor, pulleys, steel wire ropes, a guide rail and a lower ladder. In operation, the hydraulic cylinder stretches, and the upper ladder and the middle ladder rotate in the horizontal plane; parallel hydraulic cylinders stretch, so that the middle ladder swings in a longitudinal surface; the lower ladder is nested in the middle ladder; the hydraulic motor can draw and release the two steel wire ropes, and the lower ladder stretches via the transmittance by a pulley block. The articulated extension ladder for ships is used for the channel connection of two ships or ships with an offshore platform, is used for bearing the walking of people and transportation of light goods, has four degrees of freedom, is flexible in extension angle, is small in floor space in the closed state, is large in operation range, and has a wave compensation function.
