About this file
This document contains questions submitted in response to a Request for Information and the corresponding government responses regarding Solicitation Number W911XK23Q0004 for a jacking system for a self-elevating marine platform. The solicitation seeks a jacking system that can operate in currents up to 3 mph and winds up to 25 mph, with a maximum out of level condition of 1.5 degrees and draft of 7 feet. The existing modular barge will be assembled after receipt of the jacking system. The rate of lifting and lowering must fall within a range of 6 to 18 inches per minute for the full cycle. A spring applied brake in the drive line nearest the piston meets the criteria for braking in case of power loss. No other drawings or specifications of the barge were provided in the solicitation.

RFI Questions & Responses Solicitation No. W911XK23Q0004
Jacking System for Self-Elevating Marine Platform
Question 1: What is the expected side loading on the elevating legs related to water current, wind & out of “level” (expected angle). Related to 1.1.5 combined with barge draft depth, river currents & expected frontal area?
Government Response: Operated in currents with maximum 3 MPH. Operated in wind conditions with maximum 25 mph. Maximum out of level condition of 1.5 degrees.
Maximum draft 7'. Expected frontal area should be considered for worst case scenario.
Question 2: Are there any existing drawings, sketches, or photographs of the modular barge in the configuration shown on pg. 8 fig 1 of solicitation?
Government Response: No, the existing floats will be assembled after receipt of the jacking system.
Question 3: Is the elevating spud shape able to be square vs round? Which shape is preferred?
Government Response: No shape preference, however, must meet cross sectional area requirements.
Question 4: 1.5.3 Is all information required in 1.5.3 due after contract is awarded or accepted?
Government Response: Requirements located in 1.5.3 is separate from proposal requirements identified in 1.1.5. Requirements of 1.5.3 is due at acceptance of the final deliverable.
Question 5: Regarding the rate of rising and lowering the barge, is this a range? Y/N. Would a range
0-18 in/min (adjustable) be sufficient? Does 6-18”/min include clamp, unclamp, reset travel, actual move cycle time? Maybe clarify the measurement method. For example:
move 60ft (720 in) in 120 minutes @ (6”/min) & 720” in 40 minutes @ 18”/min.
Government Response: Maximum operating speed must fall within a range of 6in/min to 18in/min for full cycle. A variable lifting speed is acceptable, but not a requirement.
Question 6: For rack and piston design, spring applied brake would be in the drive-line nearest the piston(s). Brakes are applied as required, and as a fail safe related to loss of power.
Manual override is performed using a portable hand pump (port-a-power). Does this meet criteria of 1.3.6?
Government Response: There is no requirement to manually override the disengagement of brakes in case of loss of power. The proposed design meets the criteria contained in 1.3.6.
