A dry dock (sometimes drydock or dry-dock ) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance , and repair of ships , boats , and other watercraft.
63-605: Two ships in the Confederate Navy were named CSS Nashville in honor of Nashville, Tennessee. CSS Nashville (1861) was a steamer , seized in 1861. She was a blockade runner, renamed Thomas L. Wragg and later commissioned as the privateer Rattlesnake and destroyed in 1863 CSS Nashville (1864) was a large side-wheel steam ironclad built in 1863 See also [ edit ] USS Nashville [REDACTED] [REDACTED] List of ships with

And in the trench he built props of solid stone five cubits deep, and across them he laid beams crosswise, running the laces whole width of the trench, at four cubits' distance from one another; and then making a channel from
189-415: A dock for a vessel of such a size might have had a volume of 750,000 gallons of water. Before the 15th century, when the hull below the waterline needed attention, careening was practised: at high tide the vessel was floated over a beach of hard sand and allowed to rest on one side when the tide receded. An account of 1434 described how a site near Southampton with a bottom of soft mud was selected for
252-530: A formidable naval force, a Confederate Congress committee on August 27, 1862, reported: Before the war, nineteen steam war vessels had been built in the States forming the Confederacy, and the engines for all of these had been contracted for in those States. All the labor or materials requisite to complete and equip a war vessel could not be commanded at any one point of the Confederacy. [The Navy Department] had erected
315-410: A high cost. A floating dry dock is a type of pontoon for dry docking ships, possessing floodable buoyancy chambers and a U-shaped cross-section. The walls are used to give the dry dock stability when the floor or deck is below the surface of the water. When valves are opened, the chambers fill with water, causing the dry dock to float lower in the water. The deck becomes submerged and this allows
378-708: A number of ropes attached to the superstructure. The Saint-Nazaire 's Chantiers de l'Atlantique owns one of the biggest in the world: 1,200 by 60 metres (3,940 ft × 200 ft). The Alfredo da Silva Dry Dock in Almada , Portugal , was closed in 2000. The largest roofed dry dock is at the German Meyer Werft Shipyard in Papenburg , Germany , it is 504 m long, 125 m wide and stands 75 m tall. Harland and Wolff Heavy Industries in Belfast , Northern Ireland ,

It has established eighteen yards for building war vessels, and a rope-walk, making all cordage from a rope-yarn to a 9-inch cable, and capable of turning out 8,000 yards per month .... Of vessels not ironclad and converted to war vessels, there were 44. The department has built and completed as war vessels, 12; partially constructed and destroyed to save from
504-546: A roof, to prevent spy satellites from taking pictures of the dry dock and any vessels that may be in it. During World War II , the German Kriegsmarine used fortified dry docks to protect its submarines from Allied air raids (see submarine pen ). An advantage of covered dry docks is that work can take place in any weather; this is frequently used by modern shipyards for construction especially of complex, high-value vessels like cruise ships, where delays would incur
567-460: 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. 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
630-472: A small Italian book printed in Venice in 1560, called Descrittione dell'artifitiosa machina . In the booklet, an unknown author asks for the privilege of using a new method for the salvaging of a grounded ship and then proceeds to describe and illustrate his approach. The included woodcut shows a ship flanked by two large floating trestles, forming a roof above the vessel. The ship is pulled in an upright position by
693-412: A temporary revetted bank of rock and clay that had to be dug away by hand (an operation taking typically 29 days, working night and day to accord with the tides ) to allow the passage of a ship. Emptying was by a pump, possibly in the form of a bucket-chain powered by horses. This dry dock currently holds First World War monitor HMS M33 . Possibly the earliest description of a floating dock comes from

The Confederacy had a few scattered naval assets and looked to Liverpool, England, to buy naval cruisers to attack the American merchant fleet. In April 1861, Mallory recruited former U.S. Navy Lieutenant James Dunwoody Bulloch into the Confederate navy and sent him to Liverpool. Using Charleston-based importer and exporter Fraser Trentholm, who had offices in Liverpool, Commander Bulloch immediately ordered six steam vessels. As Mallory began aggressively building up

It is operated by Vigor Industries in Portland, OR, in
1008-525: The Battle of Hampton Roads between Monitor and Virginia greatly overshadowed the bloody events each side's ground troops were fighting, largely because it was the first battle in history between two iron-armored steam-powered warships. The last Confederate surrender took place in Liverpool , United Kingdom on November 6, 1865, aboard the commerce raider CSS Shenandoah when her flag ( battle ensign )
1071-476: The Ottoman Empire , and Germany . However, the United States did not acknowledge the Confederacy as an independent country and denied the legitimacy of any letters of marque issued by its government. U.S. President Abraham Lincoln declared all medicines to the Confederacy to be contraband and any captured Confederate privateers were to be hanged as pirates. Ultimately, no one was hanged for privateering because
1134-527: The Union Navy . It instead sought to take advantage of technological innovation, such as ironclads , submarines , torpedo boats , and naval mines (then known as torpedoes). In February 1861, the Confederate States Navy had 30 vessels, only 14 of which were seaworthy. The opposing Union Navy had 90 vessels. The C. S. Navy eventually grew to 101 ships to meet the rise in naval conflicts and threats to

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. Shipyards operate floating dry docks as one method for hauling or docking vessels. Floating drydocks are important in locations where porous ground prevents
1260-556: The 1,000-foot AFDB-1 and the 850-foot AFDB-3 . The latter, an Advance Base Sectional Dock which saw action in Guam , was mothballed near Norfolk , Virginia , and was eventually towed to Portland , Maine , to become part of Bath Iron Works ' repair facilities. A downside of floating dry docks is that unscheduled sinkings and off-design dives may take place, as with the Russian dock PD-50 in 2018. The " Hughes Mining Barge ", or HMB-1,

It included various offices, bureaus, and naval agents in Europe. By July 20, 1861,
1449-494: The Confederacy was able to construct at least twenty ironclads that were commissioned and put into operation during the war. One of the more well-known ships was the CSS Virginia , formerly the sloop-of-war USS Merrimack (1855). In 1862, after being converted to an ironclad ram, she fought USS Monitor in the Battle of Hampton Roads , an event that came to symbolize the end of the dominance of large wooden sailing warships and
1512-571: The Confederacy was the shipyard's dry docks , barely damaged by the departing Union forces. The Confederacy's only substantial navy yard at that time was in Pensacola, Florida , so the Gosport Yard was sorely needed to build new warships. The most significant warship left at the Yard was the screw frigate USS Merrimack . The U.S. Navy had torched Merrimack' s superstructure and upper deck, then scuttled
1575-499: The Confederate States Navy during its existence were the protection of Confederate harbors and coastlines from outside invasion, making the war costly for the United States by attacking its merchant ships worldwide, and running the U.S. blockade by drawing off Union ships in pursuit of Confederate commerce raiders and warships. It was ineffective in these tasks, as the coastal blockade by the United States Navy reduced trade by

1701-552: The Confederate economy. In May 1861, Confederate Congress appropriated $ 2,000,000 to either construct or purchase ironclad vessels in England. The Confederacy intended to use the European ironclads to break the Union blockade. Aside from those built in Europe, the Confederacy also manufactured their own vessels. Despite a lack of materials (especially iron and engines) and shipbuilding facilities,
1764-446: The Confederate government had organized the administrative positions of the Confederate navy as follows: By 1862 regulations specified the uniforms and rank insignia for officers. Petty officers wore a variety of uniforms, or even regular clothing. Officers of the Confederate States Navy used, just like the army, a combination of several rank insignias to indicate their rank. While both hat insignia and sleeve insignia were used here
1827-539: The Confederate government threatened to retaliate against U.S. prisoners of war . Initially, Confederate privateers operated primarily from New Orleans , but activity was soon concentrated in the Atlantic, as the Union Navy began expanding its operations. Confederate privateers harassed Union merchant ships and sank several warships, although they were unable to relieve the blockade on Southern ports and its dire effects on
1890-521: The First Congress expanded this to four admirals, ten captains, 31 commanders, 100 first lieutenants, 25 second lieutenants, and 20 masters in line of promotion; additionally, there were to be 12 paymasters, 40 assistant paymasters, 22 surgeons, 15 passed assistant surgeons, 30 assistant surgeons, one engineer-in-chief, and 12 engineers. The act also provided for promotion on merit: "All the Admirals, four of

It is a narrow basin, usually made of earthen berms and concrete, closed by gates or a caisson . A vessel is floated in with the gates open, then the gates are closed and the water is pumped out, leaving the craft supported on blocks. The keel blocks as well as the bilge block are placed on
2079-704: The beginning of the age of steam and the ironclad warship. The Confederates also constructed submarines , among the few that existed after the early Turtle of the American Revolutionary War . Of those the Pioneer and the Bayou St. John submarine never saw action. However, Hunley , built in Mobile as a privateer by Horace Hunley , later came under the control of the Confederate Army at Charleston, SC, but

In their haste, they failed to effectively burn the facility with its large depots of arms, other supplies, and several small vessels. As a result, the Confederacy captured a large supply of much-needed war materials, including heavy cannon, gunpowder, shot, and shell. Of most importance to
2205-598: The conflict had ended. Between the beginning of the war and the end of 1861, 373 commissioned officers, warrant officers, and midshipmen had resigned or been dismissed from the United States Navy and had gone on to serve the Confederacy. The Provisional Congress meeting in Montgomery accepted these men into the Confederate Navy at their old rank. In order to accommodate them they initially provided for an officer corps to consist of four captains, four commanders, 30 lieutenants, and various other non-line officers. On 21 April 1862,

Annual pay for commissioned and warrant officers Monthly pay for petty officers, men and boys Dry docks The use of dry docks in China goes at least as far back as
2394-421: The floor of the dock in accordance with the "docking plan" of the ship. Routine use of dry docks is for the "graving" i.e. the cleaning, removal of barnacles and rust, and re-painting of ships' hulls. Some fine-tuning of the ship's position can be done by divers while there is still some water left to manoeuvre the vessel. It is extremely important that supporting blocks conform to the structural members so that
2457-499: The ironclad concept. The two ironclads had steamed forward, tried to outflank or ram the other, circled, backed away, and came forward firing again and again, but neither was able to sink or demand surrender of its opponent. After four hours, both ships were taking on water through split seams and breaches from enemy shot. The engines of both ships were becoming dangerously overtaxed, and their crews were near exhaustion. The two ships turned and steamed away, never to meet again. This part in

Apart from graving docks and floating dry docks, ships can also be dry docked and launched by: Some dry docks are used during the construction of bridges, dams, and other large objects. For example, the dry dock on the artificial island of Neeltje-Jans was used for the construction of the Oosterscheldekering , a large dam in the Netherlands that consists of 65 concrete pillars weighing 18,000 tonnes each. The pillars were constructed in
2583-404: The new " Stainless Banner ". Despite the detailed naval regulations issued, minor variations in the flags were frequently seen, due to different manufacturing techniques employed, suppliers used, and the flag-making traditions of each southern state.

On the second day of the Battle of Hampton Roads , the two ships met and each scored numerous hits on the other. On the first day of that battle Virginia , and the James River Squadron , aggressively attacked and nearly broke the Union Navy's sea blockade of wooden warships, proving the effectiveness of
2709-599: The primary indicator were shoulder straps. Only line officers wore those straps shown below as officers of various staff departments (Medical, Pay, Engineering and Naval Construction) had separate ranks and different straps. Likewise the anchor symbol on the hats was substituted accordingly and they did not wear loops on the sleeve insignias. Paymasters, surgeons and chief engineers of more than twelve year's standing ranked with commanders. Paymasters, surgeons and chief engineers of less than twelve year's standing ranked with lieutenants. Assistant paymasters ranked with masters during

It has been calculated that
2961-570: The seal of these Confederate States... President Davis was not confident of his executive authority to issue letters of marque and called a special session of Congress on April 29 to formally authorize the hiring of privateers in the name of the Confederate States. On 6 May the Confederate Congress passed "An act recognizing the existence of war between the United States and the Confederate States, and concerning letters of marque, prizes, and prize goods." Then, on May 14, 1861, "An act regulating
3024-477: The ship is finished, the gates are opened to allow water in, and the ship is carefully refloated. Modern graving docks are box-shaped, to accommodate newer, boxier ships, whereas old dry docks are often shaped like the ships expected to dock there. This shaping was advantageous because such a dock was easier to build, it was easier to side-support the ships, and less water had to be pumped away. Dry docks used for building naval vessels may occasionally be built with
3087-429: The ship is not damaged when its weight is supported by the blocks. Some anti-submarine warfare warships have sonar domes protruding beneath the hull, requiring the hull to be supported several metres above the bottom of the dry dock, or depressions built into the floor of the dock, to accommodate the protrusions. Once the remainder of the water is pumped out, the ship can be freely inspected or serviced. When work on
3150-516: The ships could be protected from the elements and avoid the damage caused by undue exposure. The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous Tessarakonteres rowing ship. However a more recent survey by Goodchild and Forbes does not substantiate its existence. But after that
3213-409: 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 hangar in which

The practice of using primary and secondary naval flags after the British tradition was common practice for the Confederacy; the fledgling Confederate navy therefore adopted detailed flag requirements and regulations in
3339-423: The upper deck was overlaid with two courses of heavy iron plate. The newly rebuilt superstructure was unusual: above the waterline, the sides sloped inward and were covered with two layers of heavy iron-plate armor, the inside course laid horizontally, the outside course laid vertically. The vessel was a new kind of warship, an all-steam powered " iron-clad ". In the centuries-old tradition of reusing captured ships,
3402-424: The use of battle ensigns , naval jacks , as well as small boat ensigns , commissioning pennants , designating flags, and signal flags aboard its warships. Changes to these regulations were made during 1863, when a new naval jack, battle ensign, and commissioning pennant design was introduced aboard all Confederate ships, echoing the Confederacy ' s change of its national flag from the old " Stars and Bars " to
3465-478: The use of conventional drydocks, such as at the Royal Naval Dockyard on the limestone archipelago of Bermuda . Another advantage of floating dry docks is that they can be moved to wherever they are needed and can also be sold second-hand. During World War II , the U.S. Navy used such auxiliary floating drydocks extensively to provide maintenance in remote locations. Two examples of these were
3528-514: The vessel; it would have been immediately useful as a warship to their enemy. Little of the ship's structure remained other than the hull, which was holed by the scuttling charge but otherwise intact. Confederate Navy Secretary Stephen Mallory had the idea to raise Merrimack and rebuild it. When the hull was raised, it had not been submerged long enough to have been rendered unusable; the steam engines and essential machinery were salvageable. The decks were rebuilt using thick oak and pine planking, and
3591-401: The warship Grace Dieu , so that the hull would bed itself in and remain upright at low tide. A timber, brushwood and clay wall was then built up around the hull. The first early modern purpose-built European and oldest surviving dry dock still in use was commissioned by Henry VII of England at HMNB Portsmouth in 1495. This was a timber-lined excavation, with the seaward end closed off by
3654-527: 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 1856 Declaration of Paris outlawed privateering for such nations as the United Kingdom and France , but the United States had neither signed nor endorsed the declaration. Therefore, privateering was constitutionally legal in both the United States and the Confederacy, as well as Portugal , Russia ,

The act of the Confederate Congress that created the Confederate Navy on February 21, 1861, also appointed Stephen Mallory as Secretary of the Department of the Navy. Mallory was experienced as an admiralty lawyer and had served for

The Hunley later sank the sloop-of-war USS Housatonic , resulting from the large blastwave that traveled from its exploding spar torpedo 's 500-pound black powder charge, during the sinking of USS Housatonic . The sinking of the Housatonic became the first successful submarine attack in history. Confederate Navy commerce raiders were also used with great success to disrupt U.S. merchant shipping.
