UNOFFICIAL MACHINERY WATCHSTANDER STUDY GUIDE This does not replace or supersede the Machinery watch stander PQS 1 Machinery watch General Watch Practices #1: Demonstrate the ability to conduct a proper Machinery watch rounds. State what machinery spaces are to be checked and how to check them: There are two types of rounds conducted during the Machinery watch. On the even hours, a machinery round is conducted. This round includes taking readings from the MPDEs, and GT if running. It also includes examination of and readings taken from any running generators. It also includes examination and readings from the steering gear rooms and shaft alleys. Once during a four hour watch, an Auxillary round is conducted. Which includes taking readings from and examining the spaces: AC flats, VCHT and lift stations, the S/W cooling pumps, the air compressors, the refers, and the ROs if running. A visual inspection is also made of the watermist stations. #3 Know the initial actions per Causality Control Manual: Read the manual. #4 Outline the important parts of the Restricted Maneuvering Doctrine (RMD) - Is set during the following conditions: - General Quarters I and III - Special Sea Detail/Nav and Anchor Detail - Underway replenishment/fueling at sea - Towing - Flight Quarters condition 1 - Law enforcement phases I, II, IV - Maintain constant communication with the OOD. #5: Read the EO’s standing orders Read and sign #6: Be familiar with the different Propulsion modes - Harbor Mode (emergency mode) – 2 lever control, each shaft controlled independently.  One main runs at a constant speed and turns both shafts. The one main is clutched in at low speed, (60 and 66s engaged clutches) and no mode can be selected on the other main. 75 SRPM max  Used in the event of a MPDE casualty or whenever the OOD wants it - Cruising Mode – single lever control  One main runs at variable speeds and turns both shafts. Control lever of the selected side controls engine speed and propeller pitch of both shafts. Engine is engaged in Low speed, (60 clutch and 66 clutches) and no other mode can be selected on the other main. - Maneuvering Mode – single or dual lever control based on number of MPDEs online  Each main drives it’s own shaft, engine speed and pitch are controlled variably by each control lever.  Only the 60 clutches are engaged on each RED Gear  When maneuvering mode is selected on one side, it may be selected on the other, or no mode may be selected at all. 2 - Gas Turbine Mode – one lever control of both shafts  The GT drives both shafts exclusively.  Speed and propeller pitch are controlled variably by one control lever.  SSS and 66 clutches are engaged - CODAG mode – one lever control of both shafts  Both mains and the GT simultaneously turn both shafts. SSS, 66, and 47 clutches are engaged  The speed of the gas turbine, the speeds of both engines and the pitch of both propellers are adjusted via one control lever. #7: What are the 5 forms of communication in ECR? - the 1 MC - Phones - Hydra radios - SPP - telegraph system #8: Reset a MCMS console: Open panel below console, press small reset button.
