3. REQUIREMENTS

3.1 General.

3.1.1 CIR. The Contractor must submit a CIR for the inspections listed in the following paragraph(s):

3.3 Maintenance tasks.

3.1.2 Tech Rep. The Contractor must provide onsite at least one QL3 certified technician on MTU4000 series engines. The technician must possess a 1B dongle, have certification on ECU-7 series governors, and the Contractor must have 20V4000 engine maintenance experience.

3.1.2.1 Most current technical documentation. Prior to starting work, the QL3 certified technician must obtain from the OEM (MTU) the most current versions of the MTU documents contained within TP-

8019A (e.g. service manuals, bulletins, etc.) and abide by requirements in those current documents. After the overhauled/repaired engines have been accepted satisfactory by the Coast Guard, turn over all new versions of documents to the Coast Guard.

3.1.3 Protective measures. The Contractor must furnish and install all protective measures in accordance with SFLC Std Spec 0000, paragraph 3.3.3 (Vessel component, space, and equipment protection).

3.1.4 Interferences. The Contractor must handle all interferences in accordance with SFLC Std Spec

0000, paragraph 3.3.5 (Interferences).

3.2 Ad-hoc test and inspections. After the start of work, when warranted/appropriate, Coast Guard may request various inspections and tests (e.g. engine performance data collection, etc.) and may request engine performance data whenever the engine is running. If it is determined that the test or inspection will add significant new costs or schedule impacts to the requirement, pricing will be negotiated and contract terms will be modified at that time.

3.3 Maintenance Tasks. The Contractor must perform the following to identify all discrepancies that may affect engine performance and to accomplish various other maintenance tasks.

NOTE

Ship’s Force will perform electrical isolation, tag-out procedures, etc.

Coordinate with Ship’s Force and ensure all of this work is complete prior to performing any maintenance.

During the course of disassembly and reassembly in conjunction with performing the tasks specified below renew all disturbed seals, gaskets, o-rings, rubber sleeves, and all other soft wearing parts.

Remove and re-install all interferences, as required, to perform the following maintenance.

Perform a sea trial and pre-test to identify all existing discrepancies/conditions. Upon completion of the sea trial, and prior to any disassembly, submit a CFR that describes all discrepancies that can be identified prior to disassembly (e.g. external damage to any component, all component/equipment performance discrepancies, etc.) and recommended repairs. To support recommendations collect and submit a minimum of 30 min of ECU/MCU engine data. Evaluate oil cooler performance and describe in the report.

Clean and inspect air flexible ducting leading to the air turbo inlets from the transition piece.

NOTE

The charge air cooler is too large to be removed as a unit from the vessel. It must first be disassembled and the core must be removed separately.

Clean the charge air cooler and inspect for leakage. Prior to disassembling the charge air cooler submit a CFR detailing a disassembly and removal plan. Initiate disassembly after the

Coast Guard approves the plan.

Drain and dispose of jacket water/coolant and engine oil, flush both systems in conjunction to

13 (Rev-0) remove all loose contaminates.

Inspect centrifugal oil filter and check bearing for wear. (refer to MA25014, Instruction for overhaul of assemblies)

Furnish and install two new starters on each engine.

Clean each engine coolant/fuel cooler.

Clean each engine oil cooler to remove all contaminants that may affect engine performance.

After cleaning, hydrostatically pressurize the water side of each cooler to at least 5 psi for a minimum of 10 min to verify no oil-side/water-side leaks. Submit a CFR to certify satisfactory completion of this work.

Furnish and install a new coolant pump on each engine.

Furnish and install a new raw water pump on each engine.

Inspect all rocker arms and valve bridges for wear. Insert an endoscope through the pushrod bore to visually inspect swing followers and camshaft running surfaces.

Furnish and install new thermostats and verify proper thermal actuation.

Perform an engine output flange to RG input flange alignment check on both engines to the nearest 0.001”. Include the alignment data collected and any recommended corrective actions in the engine mount CFR described below.

Inspect engine mounts and verify proper engine to RG alignment. Measure the buffer clearance of the resilient mounts and verify proper seating of securing screws. Check for cracks in the rubber elements, measure the size of any cracks found. Measure the height of each rubber elements. Verify proper alignment between the engine output and reduction gear input flanges. Submit a CFR detailing all findings and describe all recommended repairs.

Renew all cylinder head wearing components (e.g. springs, seals, etc.) and repair all defects found to all other cylinder head components, i.e. overhaul all cylinder heads (e.g. repair individual defects, or provide new or remanufactured heads, etc.). Submit a report detailing the maintenance actions taken to each head.

Renew all turbocharger wearing components (e.g. springs, seals, etc.) and repair all defects found to all other turbocharger components (e.g. repair individual defects, or provide new or remanufactured turbochargers, etc). Submit a report detailing the maintenance actions taken to each turbocharger.

All reports, except the final test report below, are due no later than 2/3 through the contract performance period.

Furnish and install new fuel injectors.

Inspect and clean oil indicator filter, renew the new fuel filter.

Furnish and install new jacket water/coolant, engine oil, and secondary fuel filters.

WORK ITEM 2: Bilges, Clean and Partial Preserve

1. SCOPE

1.1 Intent. This work item describes the requirements for the Contractor to clean, inspect, and partial preserve bilges.

To further clarify the intent…for the bilges listed in Table 1, Contractors seeking award of this contract are to provide pricing for 1) cleaning the bilge to identify all coatings discrepancies, 2) touch-up coating repairs of up to 9 sqft per bilge of minor defects (e.g. small rust spots, bubbled paint, etc.) in the areas that are most prone to corrosion (e.g. below strainers and condensers, along the centerline of the vessel where water will collect, etc.) as identified in

Images 1 & 2, where those discrepancies may exist, 3) performing any UT shots specified for the bilge, 4) any other coatings discrepancies known at the time solicitation was posted. Those will be listed in the last column.

Then, post award, if the contracted inspection reveals any new coatings discrepancies in excess of the 9 sqft per bilge (already priced and awarded), the Coast Guard may release a Change Request/Modification to address all or part of those newly identified coatings discrepancies.
