AUXILIARY MACHINERY CONTRACT NO. FY25 VR2 NXXXXXXXXXXX

0573 - 2

5.1 The contractor and all subcontractors, regardless of

tier must consult the General Technical Requirements (GTR) to determine applicability to this work item. In performance of this work item, the contractor and all subcontractors regardless of tier must comply with the requirements of all applicable GTRs including but not limited to GTRs 1 through 7, 22, 23, 24, 28, and 29.

5.2 The contractor and all subcontractors regardless of

tier are advised to review other work items under this contract, including but not limited to Work Items 023, 567, 569, 569, 570, 571, 572, and 901 to determine their effect on the work required under this work item. Many of the definitions relating to performance of this work item are found in Work Item 001.

5.3 Per MSC-USCG MOA dated 2018, approval is granted for

the use of MILSPEC MIL-H-24606B 1.75 inch diameter fire hose with 1.50 inch brass couplings with NH thread in lieu of UL 19.

In addition, the use of wye-gate valves with 2-1/2” inlet and 1-

1/2” outlets for fire hose connections in which the closure is composed of resilient nonmetallic material is permissible provided the station can be isolated from the fire main by a cut-out valve (COV) with metal to metal seats.

6.0 QUALITY ASSURANCE REQUIREMENTS

6.1 All items shall be serviced and maintained in

accordance with OEMs specifications and certification requirements as set forth by the USCG, ABS, and National Fire

Protection Agency (NFPA).

7.0 STATEMENT OF WORK REQUIRED

7.1 Inspect, service, and test the ship’s fire hoses and

fire stations identified in Reference 2.1 and section 3.0 using

Reference 2.2 as guidance. Accomplish inspection, servicing, and testing in accordance with IMO, SOLAS, USCG and the

Manufacturer’s requirements.

7.2 Coordinate with ship’s force to tagout all required

systems and equipment. Drain and dispose of any liquid, to vessel tanks.

7.3 Provide temporary fire hoses and equipment to

AUXILIARY MACHINERY CONTRACT NO. FY25 VR2 NXXXXXXXXXXX

0573 - 3 adequately protect the ship from fire during the accomplishment of this item. No more than 25% of the ship’s hoses should be removed at any one time. Coordinate removals with OMT REP to ensure the vessel always has adequate coverage until the hoses are returned and reinstalled.

7.4 Conduct an annual inspection of the fire hoses and

stations using Reference 2.2 as guidance. The inspection is to verify:

7.4.1 Each fire hydrant has at least one length of

fire hose, a spanner wrench, and a hose rack or other device for stowing the hose. Spanners are suitable for use on the hose at that station.

7.4.2 Each fire station hydrant or “y” branch is

equipped with a valve so that the hose may be removed while there is pressure on the fire main.

a. Inspect all flanged connections to fire main piping and hydrants for gasket material that has been identified by APB to be "readily rendered ineffective by heat". An example of gasket material that has been accepted by ABS for us in fire main and hydrant flanged connections is reddish brown Garlock

Series 9900 or equal ABS Type Approved material per ABS Rules 4-

6-1/3.5, 4-6-2/9.5 vi), 4-7-3/1.11.1. Include a listing of connection that are unacceptable or questionable to the OMT REP.

7.4.3 Firehoses are connected to the outlets. On open

decks where no protection is afforded to the hose in heavy weather, or where the hose may be liable to damage from the handling of cargo, the hose may be temporarily removed from the hydrant and stowed in an accessible nearby location.

7.4.4 Each firehose on each hydrant has a combination

solid stream and water spray firehose nozzle approved under subpart 46 CFR §162.027.

7.4.5 Visually examine each hose for broken, damaged, or missing parts.

7.4.6 In each propulsion machinery space containing

an oil-fired boiler or internal combustion machinery, each fire hose having combination nozzle must have a low-velocity water

AUXILIARY MACHINERY CONTRACT NO. FY25 VR2 NXXXXXXXXXXX

0573 - 4 spray applicator that is approved under subpart §162.027. The length of the applicator must be less than 1.8 meters (6 feet).

For Tank Vessel requirements see 46 CFR Table 34.10-10(E).

7.4.7 Each low-velocity water spray applicator has

fixed brackets, hooks, or other means for stowing next to the hydrant.

7.4.8 Firehose is not being used for any other

purpose than fire extinguishing, drills, and testing.

7.4.9 Inspect the physical condition of all hoses

checking for damage, cuts, abrasions, and mildew.

7.4.10 Visually examine the hose lining at each end

for signs of delamination.

7.4.11 Fire station hydrant connections are brass, bronze, or other equivalent metal.

7.4.12 Fire hydrants, nozzles, and other fittings have

threads to accommodate the hose connections noted below.

Couplings are to:

a. Use National Standard firehose coupling threads for the 1-1⁄2 inch (38 millimeter) and 2-1⁄2 inch (64 millimeter) hose sizes (9 threads per inch for 1-1⁄2 inch hose, and 7-1⁄2 threads per inch for 2-1⁄2 inch hose); or

b. To be a uniform design, for each diameter hose, throughout the vessel to allow for interchangeability.

c. Each section of firehose is lined commercial firehose that conforms to Underwriter’s Laboratories, Inc.

Standard 19 or Federal Specification ZZ-H-451E.

d. Ensure there is a shore connection to the fire main on each side of the vessel in an accessible location.

Ensure there is an international voyage complying with ASTM F

1121. The international connection is to be capable of being used on either side of the vessel.

7.5 Conduct annual maintenance on all fire hoses and

stations in accordance with the manufacturer’s design, AUXILIARY MACHINERY CONTRACT NO. FY25 VR2 NXXXXXXXXXXX

0573 - 5 installation, maintenance instructions and service bulletins.

The maintenance will include/verify:

7.5.1 Thoroughly wash out and clean the interior

surfaces of all exterior fire station boxes, removing all dirt, debris, mildew, and water prior to re-stowing fire hoses.

7.6 Conduct annual testing of the fire hoses using

Reference 2.2 as guidance and per 46 CFR §95.25-20(4). The testing is to include:

7.6.1 Upon vessel arrival and with assistance from

ship’s force conduct an operational test of the fire main system checking the pressure at the most remote and highest outlets.

Each fire pump must be capable of delivering water simultaneously from the two highest outlets at a pressure of approximately 50 psi per 46 CFR §95.10-5(c).

7.6.2 Hydrostatically test all firehoses to a test

pressure equivalent to the maximum pressure to which they may be subjected in service, but not less than 100 psi (690 kPa).

CONTRACTOR IS REQUIRED TO PROVIDE ALL EQUIPMENT TO

HYDROSTATICALLY TEST HOSES TO INLCUDE CALIBRATED GAGE.

7.6.3 The total length of any hose line in the hose

test layout to be service tested is not to exceed 300 feet per

Reference 2.2.

7.6.4 The hose test layout will be straight, without

kinks or twists.

7.6.5 The test medium is to be clean fresh water.

7.6.6 Ensure all air has been bled from the hoses

before pressure testing.

7.6.7 Test pressure will be held for a minimum of

three minutes.

7.6.8 Ensure the test gauge has been calibrated

within the last 12 months.

7.6.9 Upon successful completion, stencil the fire

hoses with date of each service test and the service test

AUXILIARY MACHINERY CONTRACT NO. FY25 VR2 NXXXXXXXXXXX

0573 - 6 pressure. Any new hoses will also be stenciled with the Vessel’s

Name.

7.7 Testing is to be coordinated with OMT REP and ABS and

USCG. Any firehose found to be defective and incapable of repair is to be destroyed in the presence of OMT REP. Defective hoses are to be replaced with new ship’s spares.

7.8 Care is to be used to protect the hoses and coupling

threads from damage during the accomplishment of this work item.

To prevent mechanical damage, firefighting appliances are not to be dropped or dragged.

7.9 Upon completion of all inspections, tests and repairs, return the fire hoses to the vessel and their respective station, apply a light coat of silicon-based lubricant to coupling threads, and leave fire hoses in a ready for service condition. All hoses are to be drained and thoroughly dried before being placed in storage.

7.10 Reports

7.10.1 When inspection, service and testing reveal any

deficiency a condition report is to be submitted to the OMT REP with recommended repairs and parts required. Submit one electronic copy in Portable Document Format (PDF).

7.10.2 Submit a report that includes “as released”

condition of the firehoses. Submit one electronic copy in
