Bom của Đất Việt Báo!

Trong số các loại OPV (offshore patrol vessel) thì Ấn có Samar class của Coast Guard và Saryu class cùa hải quân Ấn là đáng chú ý nhưng mua cái này hơi phí vì tải trọng của hai loại này từ 2000 ~ 2650t, trang bị yếu, đầu tư mua Project 20382 Tigr hay hơn, sau này ngon nữa thì project 11541 Korsar hay project 22350 (Admiral Sergei Gorshkov class) (tải trọng ~ 4500)

Morocco’s recent order for three Sigma multimission frigates from Schelde Naval Shipbuilding confirms the value of the ships’ modular-hull design, executives say, and opens the door to further export sales of corvettes, frigates and patrol vessels built with it.

Morocco ordered three multimission frigates from Schelde that use the shipbuilder’s Sigma modular hull design. Cre***: SCHELDE CONCEPTThe Royal Moroccan Navy signed the contract with Schelde on Feb. 6 (DTI March, p. 8). Worth approximately €510 million ($816 million), it calls for the design, build and delivery by 2012 of three surface combatants that the Moroccans are designating multimission frigates.
“This is an important development for us because it signals that the Sigma concept has merits,” says Hein van Ameijden, director of Schelde Naval Shipbuilding, which is located here. Four missile corvettes built with the Sigma design have been sold to Indonesia, but van Ameijden says some observers dismissed the deal as just another case of an old colonial power selling defense equipment to a former possession.
The Sigma design uses standard, 7.2-meter-long (24-ft.) sections separated by bulkheads with watertight doors throughout the ship. By varying the number of sections, a ship can be stretched or shortened. The Indonesian corvettes, for example, have 12 sections; two of the Moroccan ships have 13, and the third Moroccan ship has 14.
The length of the sections was set at 7.2 meters because of an international requirement that 6-meter-wide damage be survivable, says Schelde Naval Architect Leon Goossens. “Based on the 7.2-meter-section principle, such damage will result in a maximum of two sections being flooded, which is survivable.” The section dimensions also provide an extra margin to accommodate standard 20-ft. containers.
Van Ameijden says Schelde is “very much aware” of the “90:10 rule” of shipbuilding: Changing 10% of the ship requires changes to 90% of the drawings. This, he adds, is not necessary with the Sigma concept because of the high degree of standardization.
The standard-section-length principle enables Schelde to incorporate standardization within beams, doors, portals, stairs and other key construction components, saving cost and making design, engineering, purchasing and production more efficient. The interfaces between the compartments in the ship are also virtually identical, Goossens says.
Schelde has a preferred supplier base, including Imtech for the platform systems and Thales for combat systems, which helps to further reduce cost (although customers can select other vendors).
“That we were able to respond quickly to the Moroccan opportunity is mainly due to the Sigma concept and the hull-model testing done earlier,” says van Ameijden. “In simple terms, we just had to pull out the drawing, cut and paste a bit, and the new configuration was ready. The concept is modular in philosophy, comprising the whole ship instead of just modular equipment containers that can be dropped in here and there. Our concept has been extensively tested and proven at sea.
“Indonesia selected the Sigma design because it was the best, and so did Morocco,” he says.
The Moroccans came to Schelde in May 2007 after negotiations with France for new warships fell apart. “Our parent company, Damen Shipyards Group, has been doing business in Morocco for a long time and this led to the Royal Moroccan Navy contacting us,” says van Ameijden. “They were able to join a sea trial with the first of the Indonesian corvettes, KRI Diponegoro, on May 2, 2007, and the delegation also visited the Royal Netherlands Navy in The Hague and its naval base in Den Helder. That was enough for them to make up their minds—they liked what they saw.”
Production of the Moroccan ships started almost immediately after the contract was signed. The aft sections and forward sections are identical to those on the Indonesian ships. On Feb. 18, Schelde started construction of the aft section on the first ship for Morocco, which will be the stretched version and the first delivered.
“The aft section is the most critical in terms of planning because of the implications it has for the propulsion machinery. The forward sections, up to the foundation for the main gun, are being built by Buijs Co., a small family enterprise near Rotterdam that has also produced these sections for the Indonesian ships,” says van Ameijden.
Morocco decided it wanted ships based on the Indonesian corvettes but augmented with a helicopter hangar and longer-range anti-air missile system. Indonesia uses MBDA’s Tetral system that fires Mistral very-short-range missiles on its corvettes. Morocco specified MBDA’s vertical-launch Mica system that fires short- and medium-range missiles.
The Moroccan ships will feature a common, systematic arrangement, including a Thales-supplied combat system with anti-air, anti-submarine, anti-surface and electronic warfare capabilities.
Morocco also wanted robust 3D volume-search and missile-designation radar, so it selected the new Smart-S Mk. 2 from Thales. The Smart-S Mk. 2, with a range of 140 naut. mi., provides 3D target designation to the Mica missiles. Engagement coordination is performed by the Tacticos combat management system from Thales.
This is the same configuration that was specified on three patrol vessels ordered last year by Oman from VT Shipbuilding of Southampton, England. Morocco will benefit from the missile, sensor and C2 integration work performed on that program.
The Morocco contract calls for one 2,300-ton ship (designated Sigma 10513) that will be 105 meters long, with a beam of 13 meters. The other two ships will have a displacement of 2,100 tons (Sigma 9813s) and a length of 98 meters. The stretched version will have ad***ional facilities for command and control, and accommodations for 110 personnel. The other two ships will have a crew of 91.

Indonesia earlier ordered four Sigma corvettes with 12 modular hull sections. The fourth ship is under construction. Cre***: SCHELDESchelde ordered six Pielstick main diesel engines for the Moroccan ships (two in each) in late 2007 before the Moroccan contract was signed, because the line was closing down. The French supplier (formerly SEMT Pielstick, now Man Diesel SA) is able to provide the engines for Morocco, but for future ships the machinery plant of the Sigma series will be redesigned to work with other types of two-stroke diesel engines, most likely from Man or MTU.
At-sea experience with the Sigma-series corvettes for Indonesia has been satisfactory, says Goossens. The two ships delivered, KRI Diponegoro and Hasanuddin, encountered extreme weather en route to Indonesia: the former having to endure a typhoon in the Indian Ocean and the latter confronted with rough seas (Sea State 7) in the Me***erranean. “There was some minor damage but in general, both ships and their engines did well,” he says.
According to Goossens, some 60 Sigma hull-form model tests were performed at the Netherlands-based Marin research laboratory in 2002 and 2003, representing various configurations with different trim settings and ship lengths.
Schelde Naval Shipbuilding made a 10% profit (target was 5%) in 2007 and currently has its largest order book ever, worth approximately €1.2 billion, for navy and coast guard ships for Indonesia (four Sigma series corvettes, of which two have been delivered); the Netherlands (four custom-designed patrol ships); Morocco (three Sigma frigates), and Sweden (three coast guard vessels). Another large order from the Netherlands for a 26,000-ton joint support ship is expected to be awarded in early 2009, and acquisition work is continuing on ad***ional export orders.
Schelde, the only naval shipbuilder in the Netherlands, is a subsidiary of Damen Shipyards Group, which is active worldwide in commercial and military markets. Schelde focuses on the international market for patrol ships, corvettes, frigates and large amphibious support ships and helicopter carriers.
It has in recent years established a close working relationship with the Damen-owned Galatz Shipyard in Romania, although it is not involved in work for Sigma ships. “This has to do with the learning curve; they are still gearing up to work on thin-hulled ships such as the Sigmas, which use 5-mm. steel rather than the 6-12-mm. steel used for patrol ships of the Dutch navy or Swedish coast guard,” says van Ameijden.
Schelde is expecting to become even more integrated within the Damen Shipyards Group. Damen is planning to develop “more and better standard products” and will be investing in shipyards in countries with “competitive wages.” One such is Vietnam, where Damen is building a large shipyard that’s slated to start operations in 2010, which in the longer term will also provide opportunities for Schelde.
For the near future, however, Schelde will have to get the production for Morocco going while at the same time having to complete the Indonesian program and perform the detailed design and production preparations for the Netherlands patrol ship program, with that country’s Joint Support Ship looming around the corner.

Cái tàu của Ấn Độ nhìn tởm quá. Gì chứ mấy cái tàu tuần tra gần bờ cỡ đó mình làm khỏe mà. Quan trọng là mấy bác trên thực sự muốn hay không thôi. Nhìn con TP-400 đẹp và ngon hơn nhiều.

Còn ngoài Trường Sa em nghĩ làm mấy con nhỏ nhỏ kiểu như CB-90 của Thủy Điển thì ngon. Con này nếu gắn thêm mấy cái tên lửa chống tàu loại Skua của Anh nữa là hết bài. Tốc độ, tính cơ động cực cao (nhờ sử dụng 2 động cơ waterjets-các bác vào youtube xem mấy cái video clip của con này mà không ghiền mới lạ ). Có thể chở 20 lính đổ bộ. Nói chung là em cực kỳ kết con này
