Warship with massive anti-submarine capabilities were not obliged to fight with modern submarines and conventional motor boats and motor boats, whose crews are armed with hand-held instrument. If we talk about the "Undaunted", his last commander NG Abraham, who took the ship in 1992, wrote of him: "If in the Baltic Sea were at least two ships of project 11540, we actually had a search-and-strike group (PUG), which could solve the puzzle of all unsafe areas of overlap that exist there "(see Almanac" Typhoon ", vyp.21, 2/2000). And the pirates "demand" by at least 2-10-s of such ships. It turns out that the international community "to shoot sparrows with cannons." But the fight with the pirates, of course, necessary.
It should be noted that the direction of the main classes of ships to the coast of Somalia reason all the same there. In-1's, they make trips that contribute to the marine and combat training of crews. In-2, large ships have tremendous autonomy and best seaworthiness than small, and therefore more reliable. B-3, they can carry a heavy helicopter unchanging bases. Experience has shown that no helicopters fight piracy is difficult. The heavy helicopter — a "weather-resistant" and is able to put a group of special forces on the vessel suspected of piracy, and, in case of need — and saved.
The Ministry of Defence has announced it will host in September, a competition to develop the project of a new corvette for the needs of the Navy. We are talking about the ship which has come to replace the 20380 (head ship — "Guarding"). The implication is that the competition will accept the role of five companies, three of which are members of the United Shipbuilding Company. Other participants may become a foreign company and a KB, specializing generally on designing for State Courts.
The future ruler of the coastal zone
Reducing the displacement of ship significantly reduces its seakeeping and habitability, especially when the length of time in the sea. Crews "harrassed". A requirements remain the same: small displacement (Value), the highest seaworthiness (autonomy), and the presence of languid helicopter (potential).
The problem of piracy, the problem of ascertaining the legal regime of the exclusive economic zone is not only applied to the Gulf of Aden. Just there on the significant distance from its own database, it may be advisable the use of ships and ocean-sailing, ships, "self-sufficient" for a long period of time. And in the seas surrounding Russia, in one way or another, there is the problem of the protection of biological resources, the fight against illegal migration, etc.
To combat the pirates Mozgovoi offers multiple options for patrol ships with a displacement of 600 to 1200 m, filled with light helicopters constant or time-based. Among these projects is the development and Zelenodol PKB.
Indeed, the presence of such ships can reduce the price of anti-piracy operations. But for their constant need to equip items or temporary deployment, repair shops, etc. And that means, and the decision of some difficult political and inter-state legal issues.
Meanwhile, in Zelenodol PKB have a suggestion for the ship version of "modest" displacement — about 1,000 tons — over-seaworthy and habitability with the same languid basing a helicopter. In the study performed bureau environment trimaran vessel monitoring architecture.
The vessel monitoring environments such as ATS.
In the UK and the U.S. trimarans are already under construction (for example, in the United States has recently launched on the littoral combat ship Independence). Russian trimaran type CAP (ship with outriggers) is significantly different from theirs. It consists of a displacement hull and 2-side of buoyancy (outriggers), connected to the body, "bridges", in which there is all power plant (PP). Essentially, this two modules left and right sides of the execution, the substitution of which for the same, made in advance, greatly reduces repair time. Screws — in the gondola outriggers. With all of this hull is quite free from EI, which in the single-hulled vessels are usually given to virtually all the more necessary the middle part. On the trimaran feed, freed from shafting can be one hundred percent is reserved for helicopter "economy", including the hangar. It is much easier then address issues explosion safety, habitability, security, reliability, and make other regulatory requirements for the design.
Shipbuilding properties of these trimarans were tested round tests towed models in the Central Research Institute. Acad. AN Krylov and self-propelled model is about 10 meters and a displacement of 2.4 m in open water. Due to the increased width of the outriggers at the expense of greatly increased lateral stability, as well as it should, the seaworthiness of the vessel.
Model tests have shown that compared with single hull vessels (by conversion — with waves 6 points) reduced the amplitude of roll of 5-6, pitching — 3 times, vertical overload — 2.5-3 times and excitement to 4 — 5 points do not reach the threshold of sensitivity of the person 0.15 m/s2 (the beginning of motion sickness).
In tests simulated takeoff 1st of outriggers. When the respective rudder on maneuverability is not actually affected. CAP has a narrower body reduced impedance. Placement of screws in the gondola (as in the push option, and in particular — the pull) contributes to a highest efficiency. Because high-speed characteristics of the vessel did not actually suffer.
In principle, the scheme provides an overarching CAP major shipbuilding improvement, operational and economic characteristics of vessels and ships, for the construction of which it will be applied, because of its characteristics do not depend on the type of payload.
The concept of SAR, developed by Stanislav Rudenko, proved near patents, and masters and doctorate its ideologue.
Drawback of this scheme is its increased width, which, according to the views of some professionals, will make more difficult basing and dry-docking of the ship. But there is more fear than reason. With the city of gondolas and screws heel outriggers can ship with a crane or pontoon. There are other methods for docking with the use of floating docks, not exceeding the tonnage of the vessel. If there is no room at the berth, the ship can stand in the roads. For communication with the shore after their boats there.
That's why as a patrol ship for an efficient and economical to combat piracy more predpodchitelno trimaran vessel CAP schemes displacement from 600 to 1,000 tons over-seawor
thy and autonomy, carrying heavy helicopter unchanging bases. These features of the vessel type CAP consistent with study of the vessel monitoring environment and beyond the reach of single hull ships of the same displacement.
