War service

The floating drydock made the voyage to the southwestern Pacific in two separate convoys. The two sections constructed on the Gulf Coast departed Morgan City, Louisiana, on 14 July 1943, while the remaining eight sections concentrated at San Francisco, California, before putting to sea on 28 August 1943. The first two sections arrived at Espiritu Santo in the New Hebrides on 24 September, and the West Coast sections reached that destination on 2 October. Later that month, the drydock's crew began assembly procedures. On 2 November in the course of assembling the drydock, one of its sections sank, drowning 13 of her crew. By the end of 1943, she was a working drydock of eight sections repairing a variety of Navy ships at Espiritu Santo. In April 1944, ABSD-1 became a full ten-section drydock when her remaining section was combined with another from ABSD-2 and was joined to the eight already functioning. With all ten sections joined, she was 927 feet long, 28 feet tall (keel to welldeck), and with an inside clear width of 133 feet 7 inches.

She served in the New Hebrides until mid-April 1945 at which time she received orders to disassemble and move forward to the big base atLeyte Gulf in the Philippines. ABSD-1 completed disassembly by the beginning of June and, on 30 June, the first six sections began the voyage, via Hollandia, New Guinea, to Leyte. The remaining four sections took departure on 7 July. The first echelon arrived at Manicani Bay, Samar Island, on 27 July, and assembly began three days later. On 2 August, the rest of the drydock entered Manicani Bay and, by mid-September, all ten sections had been joined together. The floating drydock resumed her repair work soon thereafter, and it continued through February 1946. On 28 February 1946, she undocked four yard craft and began preparations for inactivation. ABSD-1 was decommissioned on 31 May 1946.

[edit]Post-war service

She remained in the Philippines through the summer and fall of 1946. During that time, in August 1946, the advanced base sectional dock was reclassified a large auxiliary floating drydock and was redesignated AFDB-1. Sometime after November 1946, her sections were towed from the Philippines to Pearl Harbor where they were placed in reserve. Her inactivity lasted almost exactly five years. She was recommissioned at Pearl Harbor on 2 June 1951, Captain O. J. Stien, USNR, in command. Later that month, she was towed, in sections, to Guam in the Mariana Islands where the Navy was improving another repair facility in fairly close proximity to the combat zone in the year-old Korean War. Reporting for duty on 26 June 1951, she was not completely assembled and ready for duty until the beginning of March 1952.

Active at Apra Harbor not quite three years, AFBD-1 was out of commission again and back in reserve by January 1955. She remained inactive at Guam for a little more than 15 years. In 1970, five of her sections were moved to Subic Bay in the Philippines where the floating drydock was placed in service once again on 17 November 1970. Her third period of active service proved to be her longest lasting almost 16 years. On 7 June 1979, she was named Artisan. In October 1986, Artisan was placed out of service, and her name was struck from the Naval Vessel Register. In March 1987, however, Artisanreceived a reprieve when her name was reinstated on the Naval Vessel Register.

On 16 August 1996 her Section 1D was reclassified as unclassified miscellaneous vessel IX-521, and on 2 March 1998 her Section 1C was reclassified to IX-525.

HISTORY OF U.S.S AFDB-1


HISTORY OF U.S.S AFDB-1

The U.S.S. AFDB-.1 (formerly ABSD-1) is the first of its class of advance base sectional drydocks, built by the Bureau of Yards and Docks to dock the largest combat ships now afloat and, with modifications, those larger aircraft carriers now in construction. Following the requirements set forth by the Bureau of Yards and Docks, Frederic R. Harris, Inc., the designing engineers, developed designs which permitted rapid construction, imperative under war conditions. A number of companies contracted for the construction of these drydock sections, the completed USS AFDB-1 having been built in five different shipyards in the United States, ranging from Morgan City, Louisiana, to Everett, Washington. These were the Everett Pacific Company, Everett, Washington (two sections), Pollock Stockton Shipbuilding Company, Stockton, California, (three sections), Chicago Bridge and Iron Company, Eureka, California, (one section), Pacific Bridge Company, Alameda, California, (two sections), and Chicago Bridge and Iron Company, Morgan City, Louisiana, (two sections).

Each dock section, called an AFD is composed of a compartmentalized pontoon upon which are mounted two folding wingwalls. The section, which has its dependent power plant of two diesel driven generators, pumping plants, evaporators, messing and berthing quarters, carries a crew of about fifty men. While in sailing position, the wingwalls are folded into horizontal position, thus reducing wind resistance and enabling the section to be towed more readily. Extended sea voyages can be successfully undertaken in the sailing position, which necessitates the temporary installation of pilot house, life rafts, visual and radio communications, mooring tackle, and other seagoing gear.

The AFD-7 was the first section completed. Following the successful submergence and wingwall raising tests by flotation method held on this section in Everett, Washington, a combined Christening and Commissioning

Advance Base Section Dock

Ceremony took place on 10 May 1943. Mrs. Andrew R. Mack, wife of the first Commanding Officer, sponsored the USS ABSD-1. In accordance with instructions from the Chief of Naval Operations, Captain Andrew R. Mack placed the ship in commission and assumed command of all sections comprising the USS AFDB-1 (then ABSD-1 - Advance Base Section Dock)

By being made readily available to battle damaged ships relatively close to the scene of action, the AFDB type drydock furnished a new service to the capital ships of the United States Fleet during the last war. As a matter of recent history, the USS AFDB-1 was reactivated at Pearl Harbor Naval Shipyard during the first half of 1951 and was commissioned on 2 June 1951.

Following the outbreak of the Korean action, it was decided that the time was propitious for the reactivation of a large drydock. Accordingly, it was determined to place the USS AFDB-1 into commission, and reactivation work was commenced at the Pearl Harbor Naval Shipyard in January 1951. On 2 June, the USS AFDB-1. was recommissioned at Pearl Harbor and on 4 June the first two sections in company with two auxiliary craft departed Pearl under tow for Guam, Mariana Islands. From the initial tow date until 12 October 1951, when Sections GEORGE and HOW, the final two sections arrived at Apra Harbor, ten sections and six companion craft were dispatched in several group tows to the assembly location. One week after the arrival of the first two sections, the operation of raising the wingwalls on Section ABLE was commenced and early in September the marriage of the first two units and assembly of the drydock itself got underway. The ten sections of the drydock were completely assembled in January 1952. A series of submergence tests were conducted following assembly for shakedown of the crew, structure and machinery. On 5 April 1952 during a one day final lift test the USS AFDB-1 drydocked the USS WISCONSIN (BB64). On 1 September 1952, in view of" the prevailing world situation. the USS AFDB-1, though still remaining in commission, was placed in an "Active in Reduced Service" status.

Two methods for raising and lowering the 400 ton. wingwalls have been successfully used; the flotation method, by which the flooding and pumping of pontoon wingwalls at a predetermined depth and angle enables them to be raised or lowered, and the jacking method, by which two ten ton columns and hydraulic jacks raise and lower them.

After the assembly of two or more sections has been achieved and the moorings laid, the transfer of a 250 ton Gantry Crane to each wingwall is made. With pintles and gudgeons, wedges, and welded splice plates joining the sections and making them one unit, other features are added, namely a sloping ladder and elevator on the outboard sides of the wingwalls at either end of the dock; flying bridges at both ends to make a continuous platform around the dock at wingwall height; a fifty foot outrigger at each end on the pontoon deck to extend the working space of the dock another 100 feet; installation of shops, offices, living spaces, and recreation facilities inside the wingwalls on the safety deck.

The USS AFDB-1 is capable of docking the largest ship afloat, and by that token is itself the largest afloat. At the same time., as a mobile unit, the dock may be moved by sections through the Panama Canal from one advanced base to another. It, is also self-docking. Two or more assembled sections may dock a third section.

As each section is in itself a complete unit with identical compartmentation, the Navy Standard Divisional designations in regards to numbering and lettering of spaces are not used. All spaces such as buoyancy chambers, ballast tanks, passageways, etc., are prefixed with the letter designating the section of the assembled dock. Starboard spaces are numbered with odd numbers, and port spaces with even numbers.

1859 dry dock design


In the illustration above I give you “Nystrom’s Hydraulic Pontoon Dock” as it appeared on page 1 ofScientific American, vol. 1, num. 1, of July 2, 1859. Mr. J. W. Nystrom’s concept was to place several barges each equipped with ballast tanks and side towers side-by-side to form a dry-dock structure. In a second figure on the same page (shown below to the left) a side on view of several barges lifting a ship is shown. It was a unique and clever idea but no one seemed interested. The usual way to build a floating dry-dock is as a single structure not one of multiple barges arranged side-by-side. Below on the right is a photograph of the U.S. Navy floating dry-dock AFDM-6 (with an unidentified attack submarine inside) that show the normal construction of such structures. This dock was built in 1943 and is of the largest currently in use. It can lift a vessel of 8,000 tons displacement.



However, in 1943 the U.S. Navy needed to build a floating dry-dock large enough for battleships and aircraft carriers, displacing 60,000 and 48,000 tons respectively. Using Mr. Nystrom’s multiple pontoon configuration the AFDB-1 was constructed. This dock, shown at the right, had 10 pontoon sections. Using all 10 sections it could lift 90,000 tons.

One curious fact about AFDB-1 is that during the war with Japan its existence was classified as top secret. This put it on a par with the atomic bomb as one of the most vital pieces of information to be kept from the enemy. Mundane as it may seem the ability to dry-dock capital ships near the front was a key component to the mobile basing concept needed to project power across the vast distances of the Pacific Ocean.

But what does any of this have to do with the content of Clio Wired? Just this, Nystrom's dock, like Da Vinci's helicopter, was concieved many years before the technology was available to realize it. In the this course we have read speculations on what form new media might give history in the future. Some in the class dismissed these speculations on the grounds that the technology isn't available now to realize them and most likely won't be available in the near future. So what. At some point in time the technology will be there and historians and others whose task it will be to apply the new technology will at least have sketch of what it is they're supposed to do.

As for environmentalist concerns, they have justification. WhenMissouri was towed from Bremerton to Pearl Harbor, she was berthed for a week in the fresh water of the Columbia River to kill off Bremerton fouling and not transport it to Hawaii.

They were perfectly justified in this. When the BB Floating Dry Dock was towed from Subic Bay to Pearl, WESTPAC critters were still sticking to it and started to pollute the Mid Pacific waters of Pearl Harbor.

Strange story about that Dry Dock. It was towed from Guam to Subic Bay back in the late 70's and a Filipino friend of mine was the General Foreman Rigger in charge of erecting the side walls. Prior to the Guam assignment, that same Floating Dry Dock was berthed at Long Beach Naval Station until the 1960's.

RESOLVE Marine Group Refloats Sunken Drydock in Guam Shipyard

(3/25/2011)
Fort Lauderdale, FL, March 18, 2011 -- RESOLVE Marine Group has successfully raised and refloated the “Machinist” drydock at Guam Shipyard in Apra Harbor, Guam. The 825 ft drydock sank on January 2, 2011 during a rough weather event. RESOLVE, a marine salvage and emergency response company with extensive worldwide experience -- including prior experience raising drydocks,-- was the successful bidder for the job. RESOLVE began the salvage job on January 31 and successfully refloated the drydock on March 3.

RESOLVE’s Salvage Master, Salvage Engineer, and salvage divers first conducted a comprehensive casualty assessment to determine the structural and watertight conditions of the drydock and to ascertain the status of drydock systems. A detailed engineering analysis was undertaken and a Salvage Plan was developed and implemented, involving extensive preparatory work both topside and underwater. Given the deep submergence of the drydock well beyond normal operating limits, great care was taken to minimize hydrostatic pressures on tank boundaries during the refloating, and to keep global hull stresses and stability within allowable limits. The U.S. Coast Guard and U.S. Navy reviewed and approved the complex salvage plan.
Due to the extensive maintenance being performed on the drydock prior to sinking, a large portion of its pumping system was inoperable. To overcome this challenge, RESOLVE mobilized 12 high-capacity electric salvage pumps. Additionally, numerous gauging systems were established to monitor tank pressures and condition throughout the refloat operation. “Large sunken drydocks are notorious for testing your skill and tenacity, and this was no exception,” said RESOLVE Salvage Master Todd Schauer. “We were fortunate to have the support of an outstanding team including our client Guam Shipyard, as well as Heger Drydock and Mako Diving.”
RESOLVE Marine Group is a leading, multi-faceted marine services group specializing in marine salvage, firefighting, OPA90 SMFF emergency response, wreck removal and maritime training worldwide. RESOLVE delivers comprehensive marine services through its three divisions: RESOLVE Salvage & Fire, RESOLVE Marine Services and Resolve Maritime Academy. RESOLVE maintains fully equipped operations bases in the United States, Europe and Asia. To learn more about RESOLVE Marine Group and the full range of services offered, visitwww.resolvemarine.com .
