This file is a Questions and Answers document for RFQ 6923G526Q0051 regarding dry docking and special periodical survey services for the M/V "Seaway Guardian," a marine vessel operated by the Great Lakes St. Lawrence Seaway Development Corporation. The Q&A addresses clarifications on specific Contract Line Items (CLINs) related to fuel removal and storage, electrical consumption requirements, anode replacement specifications, lube oil tank cleaning, air pressure regulator repair, pressure relief valve specifications, radio antenna tuning equipment, owner-supplied materials, compressor specifications and serial numbers, and hull coating surface preparation requirements. Key technical details include: approximately 13,500 USG of fuel removal; 80-100 kWh/day electrical consumption at 480V, 3-phase, 200 amps; anode inspection and replacement to be determined upon drydocking; 100-125 USG lube oil tank cleaning; main engine air start regulator repair (435 psi to 150 psi station); one Kunkle 165 PSI pressure relief valve replacement; Shakespeare antennas and Standard Horizon/Sailor radio equipment; tank inspection cover gaskets as owner-supplied materials; compressor serial numbers UTY159129 (port) and UTY159130 (starboard); and full-coat Intershield 163 Inerta 160 application on underwater hull requiring complete blasting surface preparation.

| Questions & Answers |
| # | Question | Answer |
| 1 | CLIN 0002 – How much fuel should be allowed for removal, store and re-deliver? Although it is noted in CLIN 0018 that you will require 5000 additional US Gallons, we can’t seem to find the original amount. | (Note current fuel aboard 20,000 USG, upon arrival circa 17,000 USG) It is anticipated the contractor will be need to remove approximately 13,500 USG. |
| 2 | CLIN 0003 – Similarly to the above, do you have an average electrical consumption or a total amount we should allow for in our estimate? | 80-100 kWh/day summer cooling load - 3 phase, 480V, 200 amps |
| 3 | CLIN 0010 – How many anodes should be allowed for replacement? Although there is supporting documents only two anodes are clearly defined as needing repair/replacement. | "The contractor shall inspect and replace anodes that are missing or unserviceable. This includes the hull welded anodes, azimuth drives bolted anodes, sea chest anodes, and box cooler anodes. If an anode is still serviceable, but its means of connection are damaged or partially missing, the contractor shall repair the connection. For the hull welded anodes, it is known that one of the anodes is missing and one on the starboard forward side has strap welds requiring repairs. GLS will have spare hull and azimuth anodes on hand and onboard the vessel for replacement if needed due to wear or missing." |
It is unkonwn how many anodes will require replacement until the the vessel is in drydock and can be inspected.
| 4 | CLIN 0012 – How much oil should be allowed for in both the Clean Lube Oil Tank and the Bulk Lube Oil Storage Tank? | There is only the Clean Lube Oil Tank to be cleaned: 100 USG, - 125 USG including associated piping |
| 5 | CLIN 0013 – Is there any supporting information that can be provided in regard to the ‘Repair of the regulator’? | Main engine air start 3 inch pressure regulating station (435 psi to 150 psi); Station is not keeping a steady 150 psi as designed. Regulated air pressure increases over time from 150 psi up to 165-168 psi even after adjustment. Regulator is to be removed from piping spools and torn down for cleaning then testing. Repair may be needed as construction debris and sediment has been found in system since vessel delivery July 2020. No OEM data at this time |
| 6 | CLIN 0013 – Is the Pressure Relief Valve supplied by GLS? If not, do you have any supporting information on this valve? | The Pressure Relief Valve is not supplied by GLS. The Pressure Relief Valve being replaced is a /2 inch KUNKLE 165 PSI Type ABS Certified. |
| 7 | CLIN 0016 – Who is the OEM for the Radio Antenna Tuning? All other OEMs are noted in drawings and supporting details however we can’t find this one specifically. | Antennas: Shakespeare; VHF radio telephones: Two Standard Horizon Marine with Model 2200GX VHF Radios are installed above the Pilot house console. Global Maritime Distress and Safety system (GMDSS): 1. Sailor VHF radio-telephones (2 No’s), 2. Sailor MF/HF radio telephones (2 No’s) etc. |
| 8 | 3.4.4 – Although it is noted that GLS will supply anodes and drawings, is there any other Owners supplied equipment, materials or special tools in way of the OEM inspections or any planned Owners work we should be made aware of? | Tank inspection cover gaskets will be provided. |
| 9 | CLIN 0014 – Can you provide any photos of the existing compressors in their location. Quincy (The noted OEM) has requested photos of the compressors and their surroundings to get the best idea of access and any interference items. | See uploaded photos in response to Question #9. |
| 10 | CLIN 0014 – Only one serial number is provided for the compressors, can you please provide the other. | Port Compressor: Serial No. UTY159129; Starboard Compressor: Serial No. UTY159130 |
| 11 | CLIN 0007 – Task 2, bullet point 4 requests a full coat of Intershield 163 Inerta 160 on the underwater hull area, however there is no blasting or surface prep noted other than spot blasting for abrasions. As per the Application guidelines, a blast is required for maximum adhesion and quality, should this be included? | Yes. |
