Paragraph 3.7 Leak check directs contractor directs KR to accomplish a test by filling with fresh water.

Paragraph 3.8 Post Repair Testing says contractor must "test all repairs" by fill tank 4-171-3-F with water.

Modification number 2 to Solicitation Request

The porpuse of this is to clarify general requirenments and scope of work to reflect questions regarding the job requested. This adds information regarding ship check and release of technical documentation, in section 4 - NOTES. Additionally, the SOW was referencing the wrong tank # in Para 3.7 and 3.8. This is corrected as such in this revision. See rivised SOW for more information.

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.

This is modification number 01 to add date and requirement of CGC Polar Start Visit if required from any vendor interested in this solicitation.
