Allied Marine Crane Assists US Missile Defense Agency in Implementing Sea-Based X-Band Radar Operations
Allied Systems Company delivered the DTH 300-100/20 Crane, a 100-foot fixed
length boom crane with hoist capabilities of 60,000 lbs, to the AMFELS, Inc.
shipyards in July 2004, in conjunction with the United States Missile Defense
Agency’s Sea-Based X-Band Radar project.
Allied Systems Company’s DTH 300-100/20 crane will be installed on the Sea-Based X-Band Radar platform (SBX), comprised of a large X-Band radar mounted on a modified fifth-generation semi-submersible platform. It is designed to track, discriminate, and assess incoming target missiles without the limitations of a fixed location unit based on land.
The DTH 300-100/20 crane is a 100-foot fixed length boom crane with a 20-foot swing-out jib. The crane is rated for 60,000 lbs at 90 feet and 5,000 lbs at 120 feet. The crane’s main hoist is rated for 60,000 lbs with 4-part line producing a hook speed of 90 fpm. The auxiliary hoist is rated for 5,000 lbs with 1-part line producing a hook speed of 120 fpm.
The crane’s electronically controlled heave compensation system is capable of up to 100 feet-per-minute. The main hoist maintains a minimum radius of 15 feet, up to a maximum radius of 100 feet. Boom luffing speed provides maximum to minimum radius in at least 101 seconds. The DTH 300-100/20 is capable of 360 degrees of continuous slewing at 1 rpm. This specially designed crane features a totally enclosed/insulated operator’s cab, including electronic joystick crane controls, 12-volt power supply for VHF radio, heater, defroster fan, and air conditioning.
The SBX is the world’s first combination of advanced X-band radar and a state-of-the-art oceangoing, semi-submersible platform. Based on a fifth generation oil drilling platform, the SBX is a large twin hulled, self propelled vessel designed for exceptional stability in high winds and sea states equivalent to so-called “Hundred Year Storm” conditions. SBX will eventually be moved to its primary support base at Adak, Alaska, where it is scheduled to begin supporting MDA operations in 2005.
