TITLE: WATERJET MAINTENANCE – INTERIM DOCKING (2.5 YR)
QUESTION:
Paragraph 7.1 states to provide the services of an OEM Wartsila field service representative to supervise the 2.5 -year maintenance of all four (4) waterjet units while in the drydock. This 2.5 year waterjet maintenance is already the scope of WI 0929
Paragraph 7.1.1 states maintenance period will include removal and reinstallation of all four (4) jetavator assemblies, replacement of four (4) water-lubricated bearings with journals and reassembly and full overhaul of the removed waterjets at DMS facility in Chesapeake. This conflicts the first paragraph that the overhaul will be done in drydock.
With this, we would like to clarify if this work item, similar to WI 0929A?
WI 929A covers the shipyard work on the waterjets WI 992A covers the OEM support
