871 Siliman
R22T (Siliman-class) supply ship. It is a comprehensive supply ship built by China for Thailand. It was delivered for use on August 12, 1996. The ship is a large military auxiliary ship that can accompany the aircraft carrier formation to participate in ocean operations. In addition to completing the formation replenishment of various dry cargo, liquid cargo, and equipment In addition to ammunition, it can also undertake various tasks such as emergency rescue of the sick and wounded and temporary command of formations.
The engine room is located at the rear of the ship and uses two 16PC2-6V400 medium-speed diesel engines as main engines. The engines are produced by Hudong Shipyard according to French patent drawings. The total power of the two main engines is 17,600 kilowatts. , twin-shaft twin propeller propulsion, using 4-blade variable pitch propellers. The main power station is equipped with 4 generator sets, each with a rated power of 1,000 kilowatts. The diesel engine of the power station uses the MAN20/27 diesel engine produced by the technology introduced by Xinzhong Power Engine Factory.
The generator is a Siemens 1FC6 generator produced with technology introduced by Wuxi Motor Factory. The total power of the main power station is 4,000 kilowatts. It is also equipped with a 200-kilowatt emergency power station. The ship is also equipped with advanced communication and navigation equipment, including 2 radio stations, 2 navigation radars, one of which can double as a helicopter guidance radar, and a GPSMX1105 global positioning system. Department meter, etc.
The "Similan" has various supply forms such as horizontal, longitudinal, and vertical. There are 4 sets of dry and liquid cargo dual-purpose supply stations in the middle of the ship. Under level 5 sea conditions, when the supply speed is 12-18 knots, diesel, aviation kerosene, and lubricating oil can be simultaneously supplied to the receiving ships on both sides. , fresh water and all kinds of dry goods including missiles and torpedoes.
The horizontal supply device uses the product of a Dutch company. The steel cables set up between the receiving ships can transport ammunition containers, torpedoes, missiles, general cargo baskets or personnel, and can be supplied on two seats. There is a supply command and control center in the middle of the gantry, where supply officers can command and control the operations of four groups of supply stations in all directions.
There is a longitudinal liquid cargo replenishment device on the lower deck at the stern of the ship, through which various liquid cargoes can be replenished to the receiving ship sailing following the stern. There is a helicopter landing platform and hangar on the upper deck at the rear, and a helicopter control tower above the hangar. The ship can dock a large helicopter, and the helicopter can carry out vertical supply of special items and emergency transportation of the sick and wounded. .
It also has an ambulance medical cabin, an operating room, a dental room and a cabin for minor and severe patients, and is equipped with a full-time military doctor, who can provide emergency treatment to seriously injured patients. There is a spacious cargo transfer area below the main deck. aisle. Forklifts carrying ammunition containers or towed torpedoes and missile carriers can transport ammunition or mines from the ammunition depot or mine and ammunition depot to the designated location conveniently and quickly, and then send them to the cargo station on the main deck through the elevator. The lift is imported from abroad and can lift 6 tons of cargo at a time.
Explosion-proof safety measures have been taken in the storage and transportation areas of ammunition and mines. The explosion-proof area and living area are strictly divided. There are three places with different temperatures on both sides of the front of the transportation channel. Freezer and cold storage, with temperatures of -18°C, 5°C, and 15°C respectively, can store meat, vegetables and grains for a long time. The ship also has a library, officer and petty officer recreation rooms, gym, conference rooms, etc. Its design is beautiful and elegant, and its decoration is beautiful, which is well received by users.
The "Similan" is also designed to be equipped with considerable self-defense equipment. It includes 1 medium- and long-range air and sea search radar, 4 dual 37mm automatic cannons, 2 tracking radars, 2 fire control directors, and 1 passive jamming electronic warfare system. These armament plans were realized in the second phase of the project, but were delayed due to the economic crisis in Southeast Asia.
The overall design of the ship adopts a double-bottomed double-hull structure, which is a new breakthrough in my country's military auxiliary ships. It greatly improves the ability to resist damage and prevent marine pollution and can meet the requirements of the International Convention on Marine Pollution Prevention. requirements, with the current international advanced level.
The main engine, power station monitoring and ship-wide damage control system adopt centralized and unified management and are designed by the German MTU company. This monitoring system is safe and reliable. It realizes centralized monitoring of drone cabins, damage pipes and liquid levels in various oil tanks, and uses a computer system for centralized management.
For the first time, a fully enclosed cabin design is adopted for a large 22,000-ton military auxiliary ship.
Except for special parts, there are basically no portholes, allowing centralized air conditioning and air supply throughout the ship. The air conditioning system imported from the Netherlands is selected, which is safe and reliable. When the external ambient temperature is as high as 40°C, the indoor temperature can be maintained at around 24°C to adapt to the hot combat environment.
For the first time, its transverse supply device adopts a cylinder-type tension compensation device. This device can adjust the tension of the steel cable in a timely manner according to the changes in the tension of the steel cable between the supply ship and the receiving ship in wind and waves, so that the force remains constant. Its single-pass carrying capacity reaches 2 tons, which enables it to replenish ship-to-ship missiles, ship-to-air missiles and torpedoes while traveling at sea, filling the domestic gap in this field. The ship also has a dedicated pipeline for replenishing JP5 aviation kerosene and an inert gas protection system that can replenish large amounts of aviation kerosene.
The "Similan" adopts a transverse supply device imported from the Netherlands. "Similan" has a bulbous nose. Main dimensions: 171.4 meters long, 24.6 meters wide, 15 meters deep, 9 meters draft.
