    Study Notes

    Machinery Watchstander Study Guide

    • This guide does not replace the Machinery watchstander PQS.

    General Watch Practices

    • Machinery watch rounds: Two types are conducted. Even-hour rounds examine MPDEs, GT (if running), and generators. Auxiliary rounds (every four hours) check AC flats, VCHT, lift stations, S/W cooling pumps, and air compressors, referring to the Causality Control Manual.

    • Causality Control Manual: Know the procedures for initial actions.

    • Restricted Maneuvering Doctrine (RMD): Conditions include general quarters (I and III), special sea detail/nav, underway replenishment, towing, and flight quarters. Phases 1, II, IV apply for law enforcement procedures.

    • Propulsion Modes:

      • Harbor Mode (emergency): Two-lever control, each shaft is managed independently. One main runs at constant speed while the other is clutched at low speed. Maximum speed is 75 RPM.

      • Cruising Mode: One-lever control. One main runs at variable speed, controlling both shafts.

      • Maneuvering Mode: Single or dual lever control (based on online MPDEs). Each main controls its own shaft independently.

    Machinery Spaces

    • Fire Extinguishers and EEBDs (Emergency Engine Bilge Drains): Locations for AMR and FMMR extinguishers and EEBDs are detailed for upper and lower levels, in various machinery spaces (e.g., VCHT room).

    Communication and Controls

    • Machinery Control Room (ECR) communication: Five methods: 1MC, phones, hydraulic radios, SPP, and telegraph system.

    • Main Diesel Engine (MPDE) Locations: Ensure the correct locations for securing the MPDEs are known (e.g., local operating panel (LOP), outside main space, and emergency secure procedures).

    • Fuel Guillotine Valves: Locations are across the aft AFFF station.

    • MPDE Safety Interlocks: Include air flaps (small red painted handles), jacking gear, cover, ready for operation, and RED gears correctly engaged and locked.

    Alarms and Controls

    • Alarms and resets: Methods for checking and resetting alarms on control panels are detailed. Refer to MCMS for assistance.

    • Remote to Local Control: Procedures for transferring MPDE controls from remote to local mode (and vice versa) are explained.

    • MPDE Ready for Operation: How to put the MPDE in ready mode according to EOSS is detailed. This involves ensuring the correct safety measures are in place before engaging.

    • MOV and Strainers: Knowledge of how to shift and inspect a strainer is needed.

    Specific Equipment Information

    • Gas Turbine (GT) Mode: GT drives both shafts exclusively; speeds and propeller pitch are controlled by one lever.

    • CODAG Mode: When both GT and the mains are running, both run their own shafts simultaneously.

    • Specific components: Various machinery parts are discussed, including fuel filters, oil filters, coolers, and separators, as well as their functions and locations (e.g., SEPAR coalescers, centrifuge L/O filter, coolers, air coolers).

    • Jacket Water Coolers: A discussion of their purpose is included (cooling jacket water, cooling unburnt returning fuel).

    • Air Flaps and Procedures: Procedures for when air flaps are engaged/disengaged.

    • Fuel and Oil Valves: Positions of vital valves needed to understand the engine operations.

    • Watermist Systems: Includes the operation and inspection.

    • Alarm Procedures: Know how to check and reset alarms for various machinery components.

    • Engine Starting Procedures: Various aspects of engine start-up/shutdown to be familiar with.

    • Other Equipment: Know the locations, functions, and actions needed for various components such as generators and hydraulic controls.
