About this file
This document is an Amendment 2 to a Solicitation (70Z08026QMECP0006) for the CGC Northland Main Diesel Engine Renewal FY26. The solicitation involves replacing the main diesel engine due to crankshaft thrust and block measurements being out of specification. Key details include:
Work conditions allow 24/7 operations with personnel living onboard the vessel. The contractor (KTR) is responsible for hotel services but not crew meals. The engine replacement involves an Alco 251 engine, with soft parts and seals provided in an overhaul kit. After engine overhaul, break-in will follow Fairbanks Morse Defense Alco 251 Engine Break-In Procedures. Technical considerations include a pier weight restriction of 60,000 psf, requiring an outrigger bearing pad, and the United States Coast Guard will confirm parts availability. Multiple work shifts are permitted, and there is no plan for in-water engine removal.

CGC NORTHLAND MAIN DIESEL ENGINE RENEWAL FY26
SOLICITATION 70Z08026QMECP0006 AMENDMENT 2
QUESTION 1:
1. We notice the desired pop is the same as what is given for an FRC QL3, but the scope of this project is exponentially larger. If we must work 24/7 to facilitate completion on time, will that be allowed? Will personnel be living on board the vessel?
ANSWER 1:
Yes, 24/7 work is allowed, and there will be people living onboard.
QUESTION 2:
2. If the removal plan requires disruption of hotel services or eliminates access to the mess deck (like the CG Yard plan does) will we be responsible for providing the hotel services and meals for the crew?
ANSWER 2:
KTR is responsible for hotel services, but not meals for the crew.
3. What is the reason for replacing the engine? Was there a catastrophic failure that may have contaminated auxiliary systems? If so, please provide details so that our proposal can include a plan for cleaning those systems.
ANSWER 3:
The reason for replacing is crankshaft thrust was found to be out of spec, and block measurements are out of spec requiring block and crank replacement.
QUESTION 4:
4. Is there a plan, like with the FRC engine changeout, from a naval architect showing any need for counterweights or structural support when or if the decks are removed to facilitate the engine removal?
ANSWER 4:
No, there is not a plan for in-water engine removal.
QUESTION 5:
5. What are the specific engine testing requirements for the #1 (STARBOARD) MPDE from this renewal?
ANSWER 5:
After engine overhauls, we break the engine in as per Fairbanks Morse Defense Alco 251 Engine Break-In Procedures.
QUESTION 6:
6. Are multiple work shifts allowed on vessel during this repair period?
ANSWER 6:
Yes, work can be conducted 24 hours a day.
QUESTION 7:
7. The softs parts (Gaskets and Seals) not included in GFP of SPEC need to CFR or included in proposal?
ANSWER 7:
Soft parts and seals are provided in the Alco overhaul kit on the GFP list. Any additional soft parts that may be needed can be provided by the CG or via CFR.
QUESTION 8:
8. The specialty dowls for block to oil pan, pump mounting plate and fitted bolts for rear seal not included in GFP of SPEC need to be CFR or included in proposal?
ANSWER 8:
The dowels can be procured by the CG or via CFR in not included with the new block/oil pan. Please provide more information regarding the fitted bolts. The Alco 251 does not have a rear seal, as it uses an oil catcher.
QUESTION 9:
9. Weight restriction of pier?
ANSWER 9:
60,000 psf is the point load limit for bearing. Outrigger bearing will require the use of a “DICA” or similar pad.
QUESTION 10:
10. Will USCG confirm parts availability?
ANSWER 10:
Yes.
