A dry dock system comprising a first floating dock able to receive at least one vessel and being controllably submersible. The second dry dock able to receive a vessel and dimensionally received in the first dock. The second dock has sea valves that, when opened, allow the second dock to fill on submerging and drain on raising and, when closed, allow the second dock to float. The first dock is dimensioned so that it can contain the first dry dock and at least one vessel simultaneously. A method of dry docking is also disclosed. The method comprising submerging the first dry dock. Positioning the second dry dock having sea valves over a chosen area of the first dock. The first dock is raised to contact the second dry dock. The sea valves of the second dry dock are open and the first dry dock is then submerged. The second dry dock submerges with the first and remains in contact with the first dry dock. The first dry dock may then be raised. The second dry dock is raised with it. The second dry dock drains on being raised and can be refloated independently of the first dry dock. |
