- Description
- OVERVIEW The U.S. Coast Guard Academy (CGA) maintains two 50,000 gallon vertical steel tanks to store #6 fuel at the Boiler Plant -- tank ID# AST1 (the southernmost tank) and AST2 (the northernmost tank). The tanks were installed in 1957 and measure 23' 6" in diameter and 16' 0" in height. Drawings indicate ¼" steel for the tank bottoms and walls and 3/16" steel on the fixed roofs. The tanks sit on a bed of sand inside a concrete containment area. In 1980, the tanks were wrapped in a 2" thick insulation with aluminum sheathing. An out-of service inspection was conducted on the tanks in 2000. Ultrasonic measurements of the bottoms did not indicate corrosion at that time. The record of that inspection includes thickness measurement diagrams and information on pitting, settling, etc. In August 2005, during an in-service tank inspection, twelve inspection plugs were installed along the base of each tank approximately six inches above the chine to facilitate ultrasonic thickness measurements and a visual inspection of the tank coating. Average thickness measurements obtained at the inspection plugs was 0.250 inches and the coating system appeared to be in good condition. Shell settlement measurements determined there was little overall settlement and that out-of-plane deflections were within API-653 limits. TASKS Contractor shall provide all labor and equipment necessary to clean and inspect AST1 and AST 2 in accordance with applicable standards set forth in API-653 and all applicable safety regulations. Tank inspections shall be completed by an API-653 certified inspector. Prior to starting, copies of all certifications shall be required, including but not limited to API inspector certification and confined space training certifications. Contractor shall also submit a Safety Plan for entering and working inside the tanks for CGA review. Once the certifications are received and the Safety Plan has been approved by CGA, work may commence. Task 1: Transfer Fuel - Only one tank shall be out of service at any time. 1.1 CGA will either utilize or transfer fuel from AST2 to AST1 until no more fuel can be drawn. Contractor shall pump remaining fuel from AST2 into AST1 for the cleaning and inspection of AST2. Once AST2 cleaning, inspection, and repairs have been completed, CGA will pump fuel from AST1 to AST2 until no more fuel can be drawn. Contractor shall then pump remaining fuel from AST1 into AST2 for the cleaning and inspection of AST1. 1.2Contractor shall remove any remaining sludge for proper disposal prior to cleaning and inspection of each tank. Contractor shall arrange for the proper disposal of the sludge. A Government representative will sign ALL manifests. CGA will be able transfer most of the fuel from one tank to the other with the exception of about 1000 gallons. The transfer of fuel by CGA will take a minimum of two (2) days. The remaining amount will need to be transferred from one tank to the other by the contractor. CGA will attempt to retain the minimum amount of fuel required to operate the boilers to minimize the transfer amounts. Task 2: Clean the Tanks 2.1Contractor shall clean the interior of both tanks to a gas-free state. 2.2Contractor shall arrange for the proper disposal of the oily wastewater and sludge. Task 3: Inspect the Tanks Using API-653 “Tank Out-Of-Service Inspection Checklist” the Contractor shall: 3.1perform a visual inspection of the exterior of the tanks and appurtenances (keeping in mind that the body of the tank is wrapped in insulation), including but not limited to walkways, ladders, piping, vents, manways, and tank pad. The inspector shall draw from API-653, NFPA codes and professional expertise in making the assessment of the tanks. 3.2obtain shell settlement elevations. The overall and adjacent settlements will be evaluated against the calculated allowable limit as determined under API-653. 3.3inspect roof structures and obtain ultrasonic thickness measurements of the roof plates. 3.4perform a visual inspection of the interior of the tanks according to API-653. 3.5obtain ultrasonic thickness measurements of bottom and first course shell plates. Measurements will also be obtained at intervals around the perimeter of the tank. 3.6 develop a pit depth profile. 3.7obtain bottom plate topography measurements. 3.8measure the relative elevation of the columns. 3.9test the plate-to-plate seams. Liquid penetrate test procedures will be performed, if required, on welds that are inaccessible or otherwise suspect. 3.10perform a detailed inspection of the coating system including a spark test inspection to locate holidays in the coating. The tanks are not known to be coated except for an epoxy coating applied during the 2000 inspection to the tank bottoms and two feet up the side walls. Task 4: Identify Necessary Repairs and/or Problems 4.1The fuel level gauge, float and tape reader is currently broken in AST2. Contractor shall repair the gauge, float and tape reader in AST2. 4.2Contractor shall inform the Project Manager immediately if inspection reveals the need to make any other repairs, including the exact nature of the work required in order to return a tank to service. 4.3Contractor shall inform the Project Manager immediately if inspection reveals that a tank has failed (i.e., leaked). Task 5: Reports 5.1Contractor shall prepare a written inspection report detailing the condition of the twin tanks. The report shall be prepared by a Connecticut licensed professional engineer and shall include: 5.1.1 Data collected, 5.1.2 Photographs and sketches, 5.1.3 Recommendations for repairs or improvements required to keep the tanks in service or to extend the serviceable life of the tanks, 5.1.4 A list of required work to bring the system in conformance with standard industry practice, NFPA codes, etc. based on the inspectors professional expertise, and 5.1.5 Recommended future schedule for inspection. 5.1.6 Provide a compact disc containing entire final report. SCHEDULE On-Site Work Contractor shall provide a schedule of on-site work with the proposal. Due to the CGA academic schedule, the all on-site work must be completed between June 7 – 25, 2010. The Government must approve any extension of the work period in advance. Contractor shall apprise the Project Manager of any schedule slippage or unanticipated delays on a daily basis. Special Circumstances Contractor will perform the above services in accordance with the schedule outlined by the Government with the following condition: if severe weather occurs during work that hampers or impedes the work, a delay in activities may be necessary. A new schedule to be approved by the Government will be established. Severe weather may also affect the costs and may result in the need for modifications. SUBMITTALS In accordance with Task 4, Contractor shall immediately report to the Project Manager any concerns relative to a tank's serviceability. A draft of the written report described in Task 5 shall be delivered no later than thirty (30) days after the completion of the on-site work, i.e., no later than July 25, 2010. After CGA review and comment, Contractor will deliver a final report within five (5) business days. Interested individuals please contact Mr. Kevin Gustin via email; kevin.w.gustin@uscg.mil for a complete RFQ package. An on-site visit is scheduled for February 18, 2010.
