The below question and iformation were answered on the SOW. Request release of the following documents for an active solicitation 70Z08525Q000231 on SAM.gov for CGC POLAR STAR.

Coast Guard Drawing 400 WAGB 103-003, Rev AJ, Booklet of General Plans (POLAR STAR) Coast Guard Drawing 400-WAGB 2901-3, Rev E, Tank Capacity Tables – POLAR STAR Coast Guard Drawing 400-WAGB 5501-22, Rev A, RIP-Oily Water Hldg Tks & Waste Oil Tanks Mods (POLAR STAR) 1. Since are required to supply the gaskets, what are the specs, type, model number, etc? Scope of work specifies SAE AMS C6183. Manhole covers are sized according to NAVSEA 805-1626726.

2. Also section 1.1 of the scope says the Intent is to find a leak between the 2 tanks. What does that mean? Do you mean you know 1 of the tank is leaking and or is the idea is to determine which of the 2 tanks has a leak? Or does it mean that there is a leak physically occurring in a pipe that connects the 2 tanks? And the leak is not in either tank, but at some point (in maybe a pipe) in-between the 2 tanks? There are indications of liquid migration between the tanks shared boundary.

This is based on level soundings of the tanks level by the ship’s crew. One tank would lose liquid, while the other gains it. The tanks were opened earlier this summer while the ship was in dry dock. The leak could be due to the manhole cover, or some weld repairs conducted earlier this year. That is the purpose of the leak test to identify where the issue might be.
