A slipway is a special construction for lifting and launching watercrafts to and from the water. A slip consists of two parts – one is above water and another is under water. The part that is under water provides the possibility to dip a vessel into water. The slipway could be optionally equipped with rail tracks for ship trucks. The construction of the underwater part of the slipway is proceeding with the use of the special dredging complex. The construction of the slipway is calculated according to the weight of launched watercrafts.
