47 MLB SLEP Site Visit Questions and Answers

1. Para 076-3.1.1 states that RAM analysis will be performed on new systems, but in Para 076-3.1.2.2, the SOW mentions MTBF and MTTR predictions required for the major components of each mission critical system/equipment. This would seem to imply that reliability analysis would address equipment that may not be impacted by the SLEP. What systems and equipment are required to be addressed by the SLEP reliability analysis?

a. The only items that shall be included in the RAM analysis are equipment/systems that are renewed or replaced by the SLEP.

b. SOW Sections 076-3.1.1 and 076-3.1.2.2 Solicitation Amendment 00002 forthcoming.

2. Are the HSI analysis activities limited in scope to the systems/equipment that are impacted by SLEP changes?

a. HSI analysis activities shall apply to systems/equipment that are renewed or replaced during

SLEP, and any interface changes that occur because of the SLEP.

3. Is it the government’s preference to set up two production facilities?

a. The Government does not have a preference.

4. Will the government consider propulsion system design changes, or is the preference to renew the system in like kind (i.e. new Reintjes drive/subsystems and modern engine)?

a. The Government is not deviating from Specification Section 200-1.1.

5. Will the government permit transport of multiple out-of-service hulls during the limited production phase of the program (i.e. allow contractor to move all 12 hulls at start of Limited production phase)?

a. The government may consider permitting transportation of multiple out of service hulls only if they are on the same delivery order. As an IDIQ contract, proposals shall be priced as if shipping one MLB at a time in accordance with Section F.6 of the solicitation, using the estimated production schedule shown in the line item for the xxx7AA series of CLINs, titled "TRANSPORTATION FROM STORAGE TO PRODUCTION LOCATION." This schedule and quantities shall be used for proposal purposes.

6. How will the government expect management of long lead items with regard to 6 month cycle time of production per hull? (Specifically in regards to full production cycle). Will the government pre-order or fund long lead items ahead of DO releases?

a. The Government has a CLIN for LLTM, which allows for orders prior to production.

7. We are wondering what the operational hours are on the boats we visited compared to others in the fleet.

a. The Government will provide a spreadsheet listing the operational hours by hull. (See Site Visit

Question 7, 47 MLB Operational Hours.xlsx file)

8. Does the replacement engine require air box shut-down.

a. No, an air box shut-down is not required.

9. Who performed the original shipping/transportation of 47 MLB at initial production?

a. The USCG had a contract with Textron Marine and Land Systems to build and transport the 47B MLBs to their homeports.

10. Will the contractors be allowed to inspect 47’ MLBs that are subject to salt water?

a. There are no additional MLB pre-proposal site visits planned.

11. Can the Government provide fabrication drawings for the 47’ MLB storage cradle?

a. Yes, the fabrication drawing was provided in the 47 MLB Drawings (GFI) in FedBizOpps. See USCG drawing number 47B MLB 691-010 "Hull Cradle".

12. Does the crew remain in the same seats or swap around?

a. It is not uncommon for crewmembers to rotate through different seats in a typical underway evolution. The primary reason for the rotation is training and proficiency, but operations and towing evolutions play a major part in crew movement. The main operator chair equipped with the helm (currently the STBD steering station and the proposed center seat) would see the bulk of occupant swaps.

13. Is the towline reel failing or the frame?

a. Frame deflection causes misalignment of the bearings which results in towline reel binding/breaking.

14. Section L.9(d)(1)(ii)(B) of the RFP calls for a preliminary IMS that includes delivery of the First Article. In order to answer correctly, what contract award date would the Government like us to use and how soon after award does the Government expect induction of the First Article to occur?

a. For proposal purposes only, use anticipated award date of 30 September 2019. The delivery order of the First Article will occur at IDIQ contract award.

15. Under 233-2.3, “The propulsion engines shall develop not less than 500 BHP and shall not exceed

600 BHP at the full power setting,” is that ISO standard power?

a. Yes.

16. Specification C-1 556-1.6 states: “The steering system shall provide a minimum 23,750 in-lbs of combined torque to both rudder stocks.” The resultant torque 11,875 in-lbs per rudder seems quite high. We believe it exceeds the capacity of the existing rudder stock torque capacity. The specification requires reuse of the existing rudders and stocks. We believe the rudder torque should be closer to half the value stated for the 25 knot speed listed in the specification. Would the USCG please confirm the torque requirements for the steering system?

a. The answer to this question is pending.

17. SOW Section 039-1.4.4 [Orig] Boats not in service: There are 14 boats not in service in different locations: 1 on the East Coast, 10 in the Great Lakes, and 4 on the West Coast. 1+10+4=15, not 14, would the Coast Guard please clarify the quantity and locations?

a. There are 14 boats not in service. Please see GFI_08_MLB Locations Spreadsheet (Storage

Boats) in FedBizOpps for locations.

18. Would the Coast Guard please provide any available design information on the lifting/storage cradles?

a. The fabrication drawing was provided in the 47 MLB Drawings (GFI) in FedBizOpps. See USCG drawing number 47B MLB 691-010 "Hull Cradle".

19. Would the Coast Guard please provide any available information or a manufacturer of the

“specialized trailer”?

a. The Coast Guard does not have information regarding the procurement or manufacture of specialized trailers for transport of the 47 MLB.

20. We would like clarification over the interpretation of 233-2.4 after parasitic loads will engines still need to produce between 500-600 bhp stated in 233-2.3?. We believe the USCG’s intent of 233-2.4 is a testing requirement, and a contractor must state what the power is with these losses, and has increased the horsepower of the propulsion plant to anticipate the additional parasitic loads. Can you verify this previous statement? The USCG has not increased its speed requirement for this vessel, so increasing the horsepower to compensate for the requirement seen in 233-2.4 would dramatically increase vessel speed.

a. Specification Sections 233-2.2 and 233-2.3 establish the horsepower requirements for the propulsion engines. The proposed engine must have sufficient horsepower to meet the performance requirements and support the auxiliary power requirements.

The BHP rating of the engines shall be between 500-600 BHP (using ISO standard power ratings), and the engines shall provide sufficient power to meet the maximum speed requirement while supporting all auxiliary loads. The MLBs maximum speed shall be maintained at 25 knots with small allowances to ensure maximum speed is attained during acceptance testing. Details of the propulsion system (engines, reduction gears, propellers) is left to the contractor to design and optimize.

21. I wanted to know if this program has been awarded yet to any vendor(s). We are located in Texas and California and support programs for the 87, the 153/FRC and others through contract shops.

a. There has not been a contract award for this program as of December 2018.

22. Do the gas struts have to be renewed when renewing the watertight doors?

a. Yes. The hold open/locking arm with gas strut for each watertight door shall be renewed.
