Wu Yi fleet oiler
This vessel is designed as an AOE, in accordance with the US Navy hull classification system, which means it is a logistics ship that will supply oil, ammunition and stores to other ships in a battle group. Prior to the "Wuyi" ship, the Taiwan Navy warships mainly relied on a large 1946's antique water supply ship "Yu Tai" ship, with a full load displacement of about 16,000 tons. Because the "Jade Terrace" ship was old, had experienced high equipment failure rate, supply capacity is insufficient, Taiwan Navy determined to build a professional fast fuel and ammunition supply ship.
In 1986, the Taiwan Navy decided to design and build a truly modern, multi-functional supply ships to replace the transfer from the United States, already unbearably decrepit Yu Tai (AR-521) Fuel supply ship. The case was launched in 1986 by the Executive Yuan United Ship Design and Development Center responsible for the design. The U.S. Rosenblatt & son shipyard provided assistance to the plant based substantially on the T-AO-187 Henry J. Kaiser class combat support ship. But the Wuyi was modified from the Henry Kaiser-class, with a tonnage less than half, and the hull layout and power system was also very different). The China Shipbuilding Keelung factory was authorized to begin construction. The Keelung plant contractor on April 1, 1988 cut the first piece of steel plate, the keel was laid June 25, 1988, the ship was launched March 4, 1989,and placed in service June 23, 1990. Wuyi was the largest ship in the history of the Republic of China Navy, also the first truely professional, with navigation between the fuel / ammo / supply capacity of the multi-lateral materiel supply ship.
The Wuyi original construction budget was 13 billion Taiwan dollars, but because the Navy lacked previous experience building such ships, excessive underestimate shipbuilding costs, the entire preparation, poor master schedule construction process, resulting in an overall shipbuilding cost overruns. In the construction process, the cost of the found continued overruns, therefore invited Japanese, Korean shipbuilding industry were estimated, the results were roughly the construction costs should be 25 billion Taiwan dollars or so. Therefore, the rumor that construction Wuyi had a ten billion Taiwan dollar cost overrun are probably not groundless.
Originally the Henry Kaiser units had steel hull and aluminum superstructure, but Wuyi had a steel superstructure in order to improve fire survivability. The Wuyi hull is divided into six decks, there are five decks in the superstructure, for a a total of eleven decks. There are six booms in three rows - the front and rear two pairs are for offshore gas stations, while the center pair is a high-speed automatic transmission shuttle cars (FAST) material transfer station. The aft flight deck can park a CH-47 transport helicopter (Taiwan Navy currently no such models), providing transportation or vertical integration complement (but there is no hangar capability).
Wuyi number of ship body has six decks, boat Lou, The ship is equipped with four large tanks that can carry 9,300 tons of fuel and freshwater, and 600 tons of ammo and dry cargo. The Wuyi engine installation has two German Mann authorized Mitsubishi Heavy Industries MAN-14cy1 diesel engine, twin propulsion, power 25 000 hp. As the ship's electric power from four Mitsubishi Heavy Industries generators are responsible. It is worth mentioning that Wuyi is the ROC Navy's first ship that included female officers.
From the beginning Wuyi had a list of five degrees, the ship had an axis of bending, the power was insufficient, there was other defective gear, and the steering was poor. The Navy said these were rumors and half-truths. The Navy said the rumor that the Wuyi hull listed resulted from from a legend of the earliest photos of sea trials when, according to the parties involved in the construction. The Navy installed on the Wuyi a number of ballast tanks and piping configuration, resulting in pressurized water tank compartment delays. In order to drive out to sea in compliance with the timetable of tests, the builders had temporarily left the ballast tank divided into two. The result was that when Wuyi went to sea lightship [no load], without adjustable trim tanks, plus an approaching typhoon on the day of the trials, the bow was twisted to one side on departures, leaving evidence in a photo.
Later Wuyi was taken back to the factory to complete the ballast tanks, with a total divided into eight spaces. They are individually by pipe holes between compartments, connected for the purpose of trim. But afterwards work in the ship [according to the officers and men on duty service said] Wuyi cannot completely solve the hull trim problem. One issue was that the blueprints from the US manufacturers had mistakes, as the diameter of the pipe between the tanks were too small. This provided inadequate flow, resulting in a ballast water pressure that was too slow to immediately trim (especially the lightship condition). This produced a list. The rumor was that early in the construction the Navy found this a potential problem. However, the Navy itself calculated, together with the Department blueprint endorsed by the American manufacturers, still insisted on maintaining the original design. Another said it was Wuyi's defective design of fuel tanks, in short, have to spend a lot of effort to adjust oil tanks and water tanks to trim the hull.
In order to fix the defective trim tank, Wuyi must use high frequency generator driven pump to be adjusted, resulting in increased fuel consumption, reduced endurance. Some of the problems caused by the hull list caused trouble, for example, when the annual cruise equipped with additional Academy students using portable toilets. Because of the hull list, toilet often overflowed. Along with ship poorly designed ventilation duct, living spaces often filled with an intolerable smell.
In addition, the list may also affect the aft flight deck operations. The Wuyi flight deck was initially not accepted for use, though finally managed to pass. But the ship in service career did not see any actual use of the helicopter. Wuyi was not equipped with electronic warfare equipment, but used of manually operated RIM-72C Sea Cong Tree (Chaparral) anti-aircraft missiles. The Wuyi had Bofors 40mm/70 cannon, and later again in the bow deck mounted on each side of a T-75 20mm cannon. Later the air defense missiles were removed.
Wuyi service was included almost every year as the Friendship Fleet flagship, with a few exceptions, including in 2000 and 2009 due to the scheduled overhaul, as well as in 2007 due to engine problems and the temporary absence of the cam; among Central and No. 2000 (LST -232) tank landing ship replacement Friendship flagship after 2009 then only two Kangding class frigates visit. In 1998 the Navy flagship Wuyi led the Friendship detachment led the detachment Keelung. On the morning of April 11, because it was implementing a radar encounter fog silent training, near Pengjia Islet the ship collided with the Chinese fishing No.0953 Min. The fishing net broke, causing leaks, and there were others injured. In October 2006, Wuyi in Zuoying logistical support unit Cijin cam host plant facelift problem occurs, leading to a host damage, maximum speed of only 10, had to be repaired again in 2007, and thus missed the cruise.
The initial acceptance of the project failed when the Navy initially rejected Wuyi, but finally the Navy was able to endure, and trivialize, the problems as small to nothing. Although problematic, ine service Wuyi accompanied the Sanyo Friendship detachment sailing the seven seas. This showed the ship, even if there were many problems, was still able to make do, as the problems did not immediately affect the safe operation. Wuyi was the largest ship ever built military ships, due to the design and engineering lack of experience, possible flaws are inevitable, a similar situations also occur in the Navy of other countries. Based on these factors, the Taiwan Navy did not continue to buy the same type of ship as Wuyi. But another way of saying it is the Navy paid twice the originally planned price of the Wuyi, so there was no money for a second ship.
Taiwan's navy always wanted to get a second fuel and ammunition supply ship, to ensure that at least one supply ship was in sea duty. To tie in with the 2005 to 2006 began serving four Keelung class missile destroyers, when there were reports that the Navy planned to invest 2.6 billion Taiwan dollars, the purchase of a second fuel and ammunition supply ship with a displacement of 20,000 tons. In early 2009, many countries (including China, Japan, Korea and other Asian countries) sent surface warships escort to fight the Somalia pirates. Taiwan's navy was also interested, but unfortunately Wuyi was scheduled for an annual overhaul. There was no second ship navy supply ship to sail from Taiwan, and Taiwan's navy overall funding and combat training were inadequate.
This event increased interest to build a second fuel and ammunition supply ship. In June 2009, came the Navy is preparing to buy a new fuel and ammunition supply ship, the main design specifications based on Wuyi , and most likely by a Taiwan boat (former CSSC) contracting; late in 2009, Taiwan's navy official defense budget in 2010 to incorporate the new fuel and ammunition supply ship construction case, the total budget of 5.2 billion Taiwan dollars. In mid-December 2011, Taiwan boat beat Ching Fu, CITIC and other competitors, the official Department of Defense Armaments Bureau procurement center fuel and ammunition supply ship bid case, the bid amount is NT $ 4.09 billion, and in 21 December 2009 started construction, expected to be delivered in June 2014 to the Navy.
