Poe Lock - Ship Arrestors

The U.S. Army Corps of Engineers Detroit District is seeking firms that have the capability to provide construction services for rehabilitating the ship arrestors on the Poe Lock in Sault Sainte Marie, MI. On the Attached document is an overview of the Soo Locks facility with the Poe Lock identified. There are two ship arrestors in use at the Poe Locks. One upstream of the upper miter gates, and one upstream of lower miter gates. The existing ship arrestors utilize a 3-1/2 inch diameter steel cable permanently connected to arresting equipment on the south side of the lock. The cable crosses the lock chamber and connects to arresting equipment on the North side of the lock. The cable is lowered into place by a hydraulically operated boom. This boom raises the wire rope in order to permit ships to enter or leave the lock chamber. The ship arrestor utilizes a combination of resistance from a hydraulic cylinder and friction of the cable as it passes around various steel members that guide the cable as it arrests the motion of the ship prior to striking the miter gates. See figures Attached. The scope of the rehabilitation includes the following: 1. Rehabilitation and Installation of Spare Fender booms: Exisiting spare fender booms (2) are currently stored at the project and will be rehabilitated to include repairs and installation of heat shields. The rehabilitated fender booms will be installed and the existing fender booms will be placed on-site. 2. Removal and Disposal of Existing Equipment: Removal of the brake cylinders, bollards, quadrants, wire rope, etc. 3. Removal and Disposal of Existing Rolling Segment Buildings: The existing building housing the boom rolling segment (2 total) will be removed and disposed of. The existing buildings are made with asbestos containing wall panels. 4. Fabrication, Testing, and Installation of New Arrestor Machinery: The new ship arrestor machinery will consist of a spiral plate bolted between two gears with resistance provided by two hydraulic motors. One side of each gear in contact with the spiral plate is flat to retain the wire rope as it winds upon itself. The end of the new 3 diameter arrestor rope will be fitted with a special spelter socket and contained within the spiral plate and gear assembly, typical to that routinely used for wire rope type Tainter gate hoists. The spiral plate and gear assembly will be mounted on a shaft supported by plain greased bearings. The gears for this assembly will mate with pinions integral with a common shaft and connected to the two low speed high torque hydraulic motors. The pinion shaft will be mounted on grease lubricated plain bearings. Resistance to the drum turning is provided by a pressure relief valve in the motor hydraulic circuit. The assembly will be mounted on a frame and secured to the concrete at the top of the lock wall. Four will be required. Each unit is estimated to weight about 65,000 pounds. See figure Attached. 5. Buildings - A Ship Arrestor Building (to protect the arrestor machinery) will be required at each end of the fender boom (4 total) and will have load bearing exterior walls constructed of concrete masonry units (CMU) and architectural CMU veneer. Flat membrane roof over metal deck will slope to scuppers and conductor heads. An equipment roof hatch, sized appropriately, will be directly above the arrestor machinery to allow crane access. Building dimensions are approximately 20 x 20. 6. Miscellaneous - Replacement of boom and socket cylinders, limit switches, concrete demolition, counterweight repair, new concrete, etc. The work described above is contemplated to take place primarily during a winter shutdown (January 15 - March 25). The Contractor can perform some preliminary work including fabrication of arrestor machinery, rehabilitation of fender booms at other times, however, the existing Poe ship arrestors must remain in service. Access to the sight is limited by land. The Contractor has access across the MaCarthur and Poe Lock via Acrow bridges rated for HS-25 loading. Water access is available, but weather conditions (snow and ice) may limit this ability.
