Questions & Answers / Clarifications

• Trim Adjustment for Dry-docking (Q60): The shipyard can adjust ship's draft and trim prior to dry-docking to minimize hull damage risk. Minimizing arrival fuel oil (FO) to less than 33% and potentially ballasting a forward CO tank with fresh water (FW) can aid trim correction. A sample condition shows a displacement of 23,893 MT with specific drafts.
• CT Winch Foundation Drawing (Q61): The clear copy of Enclosure 2.2 – CT Winch Foundation Drawing is provided as attached documents.
• Mooring Arrangement and Fittings (Q62): Responses refer to provided references and WI 003 TAO187-SWI-APPROACH BERTHING AND MOORING for details on SWL of double bitts, diameter, and the type of mooring arrangement used for specific chocks and bitts.
• ROH Alongside Floating Dock (Q63): During the specified repair/overhaul period, no other ship will be docked alongside or tied up to the vessel, nor shall this ship be docked alongside or tied up to any floating dry-dock.
• Port Assessment Timing (Q64): The Port Assessment will be conducted at a time to be determined by the Contracting Officer, after award notification. If the assessment is deemed "unacceptable," a waiver can be submitted based on NCIS findings. The government will request specific company and port information from the awardee.

Questions & Answers / Clarifications

This document provides answers to a series of clarification requests (No. 29-55) related to a SAM.gov opportunity. It addresses specific questions regarding vessel specifications, equipment, maintenance, and repair procedures.

• Vessel Arrival Draft & Trim (Q29, Q54): The government can reduce vessel arrival trim to approximately 4ft (1.2 meters) by minimizing fuel oil (FO) to less than 33% and potentially ballasting a forward CO tank with fresh water. A sample condition shows a draft of 6.81m (22.3ft) forward and 6.54m (21.5ft) aft.
• Electrical Shore Power (Q31, Q46): For the 6,400Amp power cable requirement, the total load of 2400A will be carried by these 6 cables, with each cable rated for 400 amps of continuous use. All 6 cables can be connected to either the port or starboard side.
• Propeller Clean & Hull Inspection (Q32): This work can be accomplished during dry dock, though it is typically done in the water. The only difference would be the use of scaffolding.
• Main Engine Local Control Panel Service (Q33): This work item (0215) has been deleted and will be accomplished as a Service Order under an existing IDIQ. Bidders should refer to the revised Attachment J-3 Contractor Pricing Sheet.
• Port & Stbd Bridge Sliding Doors (Q44): Detailed steps for inspection, disassembly, cleaning, repair, replacement, reinstallation, testing, and documentation of sliding watertight doors are provided. This includes specific requirements for door panel condition, track alignment, gasket integrity, and watertightness testing.
• Cargo Gear Renewal Survey (Q45): The shipyard is responsible for identifying and procuring spare parts/materials for the 5-year cargo gear renewal survey. Bearings must be manufactured in the United States or Canada, with at least 50% of the bearing component cost originating from these countries.

This document clarifies several technical and logistical aspects of the opportunity. Notably, it confirms the deletion of work item 0215 and directs bidders to a revised pricing sheet. It also provides detailed procedures for specific repair and maintenance tasks, which may influence bidder understanding of scope and resource requirements.

Questions & Answers / Clarifications

This document provides answers to three questions submitted by potential bidders regarding the solicitation.

• Question 1 (Shifted Period of Performance - PoP): Contractors may propose a shifted PoP if unable to meet the required PoP due to drydock availability. The proposal must clearly justify the shift, explain scheduling limitations, and outline the new timeline. The Government will evaluate based on operational requirements and schedule impacts.
• Question 2 (Contractor Facility Definition): The Government clarified that 'Contractor Facility' includes facilities leased by the contractor and facilities of a subcontractor. However, facilities owned solely by the Prime Contractor are not considered 'Contractor Facilities' in this context. The offeror can use a subcontracted facility if all solicitation requirements are met, with the prime contractor remaining responsible for compliance.
• Question 3 (Protection and Indemnity - P&I Insurance): The U.S. Government is self-insured and does not carry commercial P&I insurance coverage.

These clarifications provide guidance on acceptable PoP adjustments, the definition and use of contractor facilities, and the government's P&I insurance status. Bidders should incorporate this information into their proposals, particularly regarding scheduling, facility arrangements, and understanding insurance requirements.
