3. REQUIREMENTS

3.1 General. Inspect, recondition, and test in place the windings of No. 1 and No. 2 Ship Service Diesel Generators in accordance with SFLC Std Spec 3100. Generator data is shown in Table 1 below.

3.2 Optional work. Perform the optional work sections of SFLC Std Spec 3100 as follows:

3.2.1 Bearing wear. Do not measure and record bearing wear.

3.2.2 Collector rings. Do not measure and record collector ring wear and concentricity.

3.2.3 Rotor extraction. Do not remove the rotor for cleaning within the compartment and reinstall it afterwards.

3.2.4 Installed prime mover. During drying operations, the installed prime mover (e.g., engine or barring gear) may not be used to spin the rotor while circulating current through the field windings.

Table 1 – Generator Data

3.3 Utility services. The use of Coast Guard utility services, both afloat and ashore, for performance of this work item is restricted as follows:

3.3.1 Electrical power. Electrical power for temporary tools and equipment used to accomplish this work item shall comply with SFLC Std Spec 0450. When no other power source options are practicable, such loads may be energized from a temporary generator located afloat or ashore in accordance with Appendix E of SFLC Std Spec 0450.

3.3.1.1 Dockside equipment. Power solely for dockside tools and equipment may be taken from the dockside electrical power distribution system in accordance with Appendix A (preferred) of SFLC Std Spec 0450 or from the shipboard electrical power distribution system in accordance with Appendix D of SFLC Std Spec 0450.

3.3.1.2 Shipboard equipment. Power solely for shipboard tools and equipment may be taken from the ship service electrical distribution system in accordance with Appendix B (preferred) of SFLC Std Spec 0450 or from the dockside electrical power distribution system in accordance with Appendix C of SFLC Std Spec 0450. All tools must be inspected by CG personnel prior to use with shipboard distribution system.

3.3.2 Potable water. Hot and cold potable water may be obtained from shipboard systems. Cold potable water may be obtained from dockside connections.

3.3.3 Compressed air. Compressed air for tools and generator hand cleaning may not be taken from the ship service air system. Air that is to be blown into a generator shall be filtered for particulate, water, and oil prior to discharge.

3.4 External heating. External heat must be applied following cleaning to dry out the windings. The heater power rating will vary with the amount of equipment to be dried, degree of enclosure, and amount of ventilation. The estimate in Table 2 below assumes that no heat is lost by radiation or by forced or natural convection; consequently, the input power rating should be increased by a few kilowatts to compensate for heat losses.

3.4.1 Limit heat input so that winding temperatures do not increase more than «dTdt»°F per hour.

3.4.2 Do not exceed a winding temperature of 167°F.

Table 2 – External Heating Data

4. NOTES

4.1 Conditional performance. This work item is performed only when warranted by the condition of the generator windings. The mere presence of dust is not sufficient justification to perform this work item.

4.1.1 Note that there is some risk that solutions used during the cleaning process may penetrate through microscopic cracks in the varnish, carrying contaminants deeper into the windings through capillary action. Once so embedded, such contamination cannot be removed and insulation resistance could actually be degraded such that a costly and time consuming rewind would be necessary.

4.1.2 Cleaning is normally only warranted when the windings have been wetted by sea water or insulation resistance trends suggest that the machine will fall below the minimum acceptable insulation resistance for operation before the next depot level availability.

4.2 Shop cleaning. This generator is (rotor only) removable from the vessel without making a hull cut. See CG Drawing 225B-WLB 201-2 for rigging path to weather including any bolted (BERP) or welded (WERP) equipment removal plates that must be removed. For machines that can be removed from the vessel through existing accesses or openings created by other work items, it is generally quicker and more cost effective to offload the affected generator from the vessel and perform the work ashore in a generator repair shop. Such tasking should be performed under “Ship Service Diesel Generator Overhaul” and not this work item.

32123_JSP_0309_225B

WORK ITEM 2: Circuit Breakers (60 Hz), Inspect and Test

1. SCOPE

1.1 Intent. This work item describes the requirements for the Contractor to inspect and test circuit breakers (60 Hz) located on the Switchboards.
