Provide all labor, material, equipment and services required to perform maintenance using Reference 2.1.1 as guidance. Perform temporary disassembly of engines and accomplish the following;

SSDG 1:

Troubleshoot start-up faults Troubleshoot lube oil priming pump failure. Provide CFR of repair plan.

Provide crew familiarization and training

SSDG 2:

Troubleshoot start-up faults Provide crew familiarization and training All parts that are required to be IMO certified for IAPP shall be procured directly from the OEM to meet IMO requirements. These parts shall be noted and included in the “as released” condition report.

Provide labor and material to temporarily install valves, fittings, and hoses to assist ship's force in filling the engine with GFM lube oil identified in Paragraph 4.2.1 and shipyard provided deionized water.

Inspection/Test Prior to engine start-up the checklist in Enclosure 2.2.1 is to be completed. This evolution is to be accounted for in the scheduling of work under this item and related items.

Notify the OMT REP when the overhauled engine is ready to be tested under ship's electrical load for an approximate period of two hours. The Chief Engineer will be responsible for engaging the unit on the vessel’s main bus. Record cylinder operating temperatures, fluid operating temperatures and pressures during load test. Submit an “as found” condition report.

Complete a performance test on each serviced engine for a minimum of four hours. Record all operating temperatures, pressures and maximum firing pressures and submit to OMT REP.

1.2 Reports

1.2.1 Provide a daily written report to the vessel’s Chief Engineer detailing actions and progress.

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).

Provide the OMT REP with a report for each engine no more than seven days after the completion of all work. Provide one electronic copy in Portable Document Format (PDF). The report will contain the following, at minimum:

Engine operating hours and serial number.

Photographs of the engine condition at disassembly and any unusual conditions.

Description of any abnormal or unusual conditions found during maintenance Measurements taken and recorded and critical clearances and adjustments. "As-found", "As-released" and acceptable ranges for measurements are to be listed in the report.

Valve lash measurements with OEM acceptable limits.

All reports and checklists are to be completed and signed by the person who carried out the inspection and maintenance work and countersigned by the OEM representative.

Painting/Lagging Prepare, prime, paint and restore all new, soiled, and disturbed surfaces to match surrounding surfaces.

Renew lagging where damaged or disturbed.

Manufacturer’s Representative Provide the services of an OEM authorized field service representative to accomplish all work and testing on the ships service diesel generators identified in section 3.0 ensuring compliance with the manufacturer’s standards and performance specifications.

This work item requires maintenance and repair actions to be performed on a MSC ship critical safety item. Only original equipment manufacturer (OEM) authorized technical field service providers or MSC qualified non-OEM technical field service providers and OEM authorized or MSC qualified non-OEM parts shall be used to accomplish the requirements of this work item for this ship critical safety item including oversight and guidance on all aspects of equipment as-found condition inspection, removal, disassembly, reassembly, repairs, modifications, reinstallation, and testing as applicable.
