46 CFR §176.804
§ 176.804 § 176.804 Machinery. At each initial and subsequent inspection for certification of a vessel, the owner or managing operator shall be prepared to conduct tests and have the vessel ready for inspections of machinery, fuel, and piping systems, including the following: (a) Operation of the main propulsion machinery both ahead and astern; (b) Operational test and inspection of engine control mechanisms including primary and alternate means of starting machinery; (c) Inspection of all machinery essential to the routine operation of the vessel including generators and cooling systems; (d) External inspection of fuel tanks and inspection of tank vents, piping, and pipe fittings; (e) Inspection of all fuel system; (f) Operational test of all valves in fuel lines by operating local…
46 CFR §199.190
§ 199.190 Operational readiness, maintenance, and inspection of lifesaving equipment. (a)Before the vessel leaves port and at all times during the voyage, each lifesaving appliance must be in working order and ready for immediate use. (b)(1) The manufacturer's instructions for onboard maintenance of lifesaving appliances must be on board the vessel. The following must be provided for each appliance. (i) Checklists for use when carrying out the inspections required under paragraph (e) of this section. (ii) Maintenance and repair instructions. (iii) A schedule of periodic maintenance. (iv) A diagram of lubrication points with the recommended lubricants. (v) A list of replaceable parts. (vi) A list of sources of spare parts. (vii) A log for records of inspections and maintenance. (2…

§ 56.01-2 -2 Incorporation by reference. Certain material is incorporated by reference into this part with the approval of the Director of the Federal Register under 5 U.S.C. 552(a) and 1 CFR part 51. To enforce any edition other than that specified in this section, the Coast Guard must publish a document in theand the material must be available to the public. All approved incorporation by reference (IBR) material is available for inspection at the U.S. Coast Guard and the National Archives and Records Administration (NARA). Contact U.S. Coast Guard Headquarters at: Commandant (CG-ENG), Attn: Office of Design and Engineering Standards, U.S. Coast Guard Stop 7509, 2703 Martin Luther King Jr. Avenue SE, Washington, DC 20593-7509; phone (202) 372-1375; email.

46 CFR §61.40-10
§ 61.40-10 -10 Test procedure details. (a) Test procedure documents must be in a step-by-step or checkoff list format. Each test instruction must specify equipment status, apparatus necessary to perform the tests, safety precautions, safety control and alarm setpoints, the procedure to be followed, and the expected test result. (b) Test techniques must not simulate monitored system conditions by mis-adjustment, artificial signals, improper wiring, tampering, or revision of the system unless the test would damage equipment or endanger personnel. In the latter case, the use of a synthesized signal or condition applied to the sensor is acceptable if test equipment is maintained in good working order and is periodically calibrated to the satisfaction of the Officer in Charge, Marine Inspecti…
DOE-HDBK-1011 Vol.4 §14-1
DOE-HDBK-1011 Vol.4 §14-1 — Test instruments for distribution maintenance Maintaining a distribution system depends on correct use of test instruments. The multimeter (analog VOM or digital DMM) measures voltage (connected in parallel across the points, high input resistance to avoid loading), current (connected in series, or via a clamp/CT for large currents, low insertion resistance), and resistance (on de-energized, isolated circuits only, using the meter's own source). The wattmeter reads true power directly by combining a current coil and a voltage coil, so it accounts for power factor, and on switchboards it is fed through CTs and PTs. The megohmmeter (megger) applies a high DC test voltage (commonly 500-1000 V) to read insulation resistance in megohms, the primary test for motor, g…
NAVEDTRA 14104 §1-2
NAVEDTRA 14104 §1-2 — Watchstanding safety, logs, and rounds Safe watchstanding rests on disciplined routine: making regular rounds, reading every gauge, feeling bearings and glands, listening for abnormal noise, and recording the results at set intervals in the engineering log. The log is a legal and technical record; readings are entered honestly and at the scheduled time, and any casualty, order, or unusual event is logged as it happens. Trends matter more than single readings — a temperature or pressure that is slowly drifting off normal is an early warning of fouling, wear, or a developing failure, and a good watchstander catches it before an alarm does. Any reading outside its normal band is investigated and reported, not simply written down. Personal and plant safety governs every …
