The upper works included several decks with palatial cabins and saloons, containing thrones and couches all ready for imperial tours of inspection. After many years, their hulls decayed and needed repairs, but the work was impossible as long as they were afloat. So in the Hsi-Ning reign period (+1068 to +1077) a palace official Huang Huai-Hsin suggested a plan. A large basin was excavated at the north end of the Chin-ming Lake capable of containing the dragon ships, and in it heavy crosswise beams were laid down upon a foundation of pillars. Then (a breach was made) so that the basin quickly filled with water, after which the ships were towed in above the beams. Then (breach now being closed) the water was pumped out by wheels so that the ships rested quite in the air. When the repairs were complete, the water was let in again, so that the ships were afloat once more (and could leave the dock). Finally the beams and pillars were taken away, and the whole basin covered over with a great roof so as to form a <a href="/wiki/Hangar" title="Hangar">hangar</a> in which the ships could be protected from the elements and avoid the damage caused by undue exposure.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup></p></blockquote> <div class="mw-heading mw-heading3"><h3 id="Europe">Europe</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Dry_dock&action=edit&section=3" title="Edit section: Europe"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading4"><h4 id="Greco-Roman_world">Greco-Roman world</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Dry_dock&action=edit&section=4" title="Edit section: Greco-Roman world"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The Greek author <a href="/wiki/Athenaeus_of_Naucratis" class="mw-redirect" title="Athenaeus of Naucratis">Athenaeus of Naucratis</a> (V 204c-d) reports something that may have been a dry dock in <a href="/wiki/Ptolemaic_Egypt" class="mw-redirect" title="Ptolemaic Egypt">Ptolemaic Egypt</a> in the reign of <a href="/wiki/Ptolemy_IV_Philopator" title="Ptolemy IV Philopator">Ptolemy IV Philopator</a> (221-204 BC) on the occasion of the launch of the enormous <i><a href="/wiki/Tessarakonteres" title="Tessarakonteres">Tessarakonteres</a></i> rowing ship.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> However a more recent survey by Goodchild and Forbes does not substantiate its existence.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1244412712"><blockquote class="templatequote"><p>But after that a Phoenician devised a new method of launching it (the <i>Tessarakonteres</i>), having dug a trench under it, equal to the ship itself in length, which he dug close to the harbour.

The walls are used to give the dry dock stability when the floor or deck is below the surface of the water. When <a href="/wiki/Valve" title="Valve">valves</a> are opened, the chambers fill with water, causing the dry dock to float lower in the water. The deck becomes submerged and this allows a ship to be moved into position inside. When the water is pumped out of the chambers, the dry dock rises and the ship is lifted out of the water on the rising deck, allowing work to proceed on the ship's hull. </p><p>A large floating dry dock involves multiple rectangular sections. These sections can be combined to handle ships of various lengths, and the sections themselves can come in different dimensions. Each section contains its own equipment for emptying the <a href="/wiki/Ballast_tank" title="Ballast tank">ballast</a> and to provide the required services, and the addition of a <a href="/wiki/Bow_(ship)" class="mw-redirect" title="Bow (ship)">bow</a> section can facilitate the towing of the dry dock once assembled. For smaller boats, one-piece floating dry docks can be constructed or converted out of an existing obsolete barge, potentially coming with their own bow and steering mechanism.<sup id="cite_ref-Noel1988pp81-82_18-0" class="reference"><a href="#cite_note-Noel1988pp81-82-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup> </p><p>Shipyards operate floating dry docks as one method for hauling or docking vessels.
