About this file

This is a specification document for drydock repairs to the USCGC SAWFISH (WPB 87357), a 87-foot Coast Guard cutter, with a performance period from February 2, 2027 to April 6, 2027. The specification comprises 42 distinct work items addressing structural analysis, hull preservation, tank cleaning and inspection, machinery maintenance, and system replacements totaling comprehensive vessel rehabilitation.

Key work items include: 3D laser scanning and structural analysis of the hull; ultrasonic testing of hull plating for thickness and corrosion; 100% preservation of underwater body and freeboard surfaces using multi-coat epoxy and ablative coating systems; cleaning and inspection of six fuel and waste tanks; renewal of propulsion shafts, bearings, and propellers; replacement of rudder assemblies, steering system components, and cathodic protection anodes; HVAC system cleaning; seawater system maintenance; renewal of watertight door assemblies; and replacement of electrical systems including intrusion detection and flood lights. The specification requires contractor conformance to Surface Forces Logistics Center (SFLC) Standard Specifications (particularly SFLC Std Spec 0000, 0740, 5100, 5550, 6310, 8634, and 8635) and relevant Coast Guard publications. Government-furnished property includes major components such as propellers, propulsion shafts, rudder assemblies, bearing carriers, transducers, valves, and electrical equipment, with estimated costs provided for each item. The contractor must maintain comprehensive quality assurance documentation, environmental compliance protocols, and fire safety measures throughout the availability, with critical inspection items required within the first 25% of the contract period. The specification emphasizes preservation of critical coated surfaces using authorized coating systems, protection of vessel systems during maintenance, and coordination with Coast Guard personnel for operational testing and inspections.

3. REQUIREMENTS

3.1 General. The Contractor must conform to all requirements specified in SFLC Std Spec 0000 and in this item, as applicable, during the performance of this availability. The requirements in this WI applies to all work under

2 (Rev-0) the scope of this contract, whether explicitly stated in all following work items or not, and to all other work subsequently authorized by changes, modifications, or extensions to the contract.

3.1.1 The Contractor must conform to all requirements specified in SFLC Std Spec 5550 and in the Fire Protection and Response work item, as applicable, during the performance of this availability.

3.1.1.1 Fire Safety Plan submission. The Contractor must submit a copy of the CFR 1915, Subpart P, Fire Safety Plan with the Contractor’s bid when work will be conducted in a Contractor–owned facility. Include any MOA(s) with local firefighting facilities.

3.1.1.2 Fire Plan submission. The Contractor must submit a copy of the developed availability specific fire plan as requested in the Fire Protection and Response work item, with the Contractor’s bid.

3.1.1.3 SFLC-PBPL Availabilities (87 WPB, 110 WPB, & 154 WPC). The Contractor must conform to SFLC Std Spec 5550 with the following amendments and supplements:

• For contracts executed at a Contractor’s facility, submit (pre-award) the facility’s Fire Safety Plan document described in 29 CFR 1915.502 – “Fire Safety Plan”. For planning assume that Coast Guard personnel will not be available to fight a fire.

• For all contracts at all facilities, submit the following information pre-award, taking into consideration how the maintenance/repairs specified in the work items will affect uninterrupted operation of the subject systems; make all necessary amendments to this submission after discussions with the COR at the arrival conference and during contract execution as emerging conditions warrant:

o Describe all anticipated needs for fire detection/alarm, fire-fighting, and shipboard lighting and communication systems supplementation (see bulleted paragraphs below) and a description of the proposed remedies/solutions (include pricing for maintaining capability in pre-award quote).

o Prior to performing weld repairs (or potentially the entire availability), the Coast Guard will be securing and electrically isolating the installed fire alarm system, in conjunction with performing other measures that will protect installed electronic systems that could be damaged by weld repairs; therefore the vessel’s installed fire alarm/detection system will potentially not be available during the performance period. Provide a supplemental temporary fire-alarm system while the installed system is down. Monitor that system for the duration of its installation.

o Describe how any required temporary/supplemental fire detection/alarm systems will notify fire responders.

o Describe all anticipated breaches of the cutter’s Fire Protection Boundaries and the proposed temporary solutions that will minimize impact on the Fire Protection Boundary’s proper function (e.g. removal of cables/hoses/etc. at the end of work day or installation of quick disconnects, installation of temporary fire curtains, etc.).

• Whenever maintenance/repairs described in work items or Change Requests necessitate securing, or making inoperable, all or part of the vessel’s fire detection or fire alarm system, submit a proposal to the COR/KO describing an equivalent method(s) for temporarily maintaining all lost functionality of the system(s). Select the most economical option(s) available (i.e. for extended loss of service of the entire system the temporary fire

3 (Rev-0) detections/alarm system described in SFLC Std Spec 5550 may be the best option, for shorter durations temporary watch standers may be more economical, etc.). After the COR has agreed to the proposal, maintain the capability of these systems for the duration of the contract to the greatest practicable extent.

• Whenever maintenance/repairs described in work items or Change Requests necessitate securing, or making inoperable, all or part of the vessel’s firefighting (e.g. fire main system, P100 and other dewatering systems, halon systems, portable fire extinguishers, etc.), lighting, and communications systems, submit a proposal to the COR/KO describing equivalent method(s) for temporarily maintaining all lost functionality of the system(s).

Select the most economical option(s) available. After the COR has agreed to the proposal, maintain fire detection/alarm/fighting and lighting/communications capability for the duration of the contract to the greatest practicable extent.

• All Fire Protection Boundaries must be left intact and functional at all times to the greatest practicable extent.

Notify the COR in writing whenever a breached Fire Protection Boundary will be left unattended outside of normal working hours (e.g. a door/hatch is made un-closable/un-securable due to repair work, an access cut is made into deck/bhd that is part of a Fire Protection Boundary, etc.). When a Fire Protection Boundary must be breached to facilitate contract work, minimize the impact using industry-standard methods (e.g. fire curtains, quick-disconnect fittings, etc.)
