#1 What project management scheduling chart is a bar chart with the activity or task descriptions displayed on the left and listed vertically from top to bottom, and the calendar displayed on the top and laid out horizontally from left to right? #2 As it pertains to graphical tools used to visualize task scheduling in project management, what statement best represents the difference between a Gantt chart and a PERT chart? #3 Overhaul of a ship at a shipyard represents an example of a large-scale project executed under contract. What characteristics best describe the terms of the project deliverables? #4 You are relieving the chief engineer on a self-propelled mobile offshore drilling unit. What machinery and equipment are you required to inspect prior to assuming your duties? #5 When analyzing trend analysis data in reference to a given limit value for the purposes of scheduling corrective maintenance, what statement is true? #6 While a vessel is underway in periodically unmanned engine room status, the oily-water separator is undergoing extensive maintenance and repairs and will not be available for service for another 24 hours. With bilge holding tanks nearing capacity, as chief engineer you wish to be informed of when the oily-water separator is available for service. How would you best insure that you will be so informed? #7 As a chief engineer, which of the following instructions would be most appropriately entered into the Chief Engineer's night orders due to the non-routine nature of the instruction? #8 As a chief engineer, which of the following instructions would most appropriately be written into the chief engineer's night orders due to the non-routine nature of the special instruction? #9 According to 46 CFR regulations pertaining to periodic tests and inspections as related to machinery and equipment, what functional test must be performed on boiler draft fans, fuel oil transfer and service pumps, and machinery space ventilation fans during periodic inspections? #10 Planned maintenance procedures are important to maintaining the operating condition of equipment. Your vessel is a single screw vessel. How often should you exam your vessel's tail shaft in order to be in compliance with Coast Guard periodic testing and inspection regulations? #11 Suppose a water-lubricated stern tube bearing is being evaluated for wear where the propulsion machinery is located amidship. If the tailshaft diameter is 10.5 inches, according to 46 CFR regulations pertaining to periodic tests and inspections as related to machinery and equipment, what would be the maximum clearance diameter permissible before the bearing must be re-bushed? #12 If two centrifuges are to be simultaneously used in series to treat residual fuel contaminated with both water and solids, how should the centrifuges be configured? #13 Which of the following statements represents acceptable practice for heavy fuel oil settling tank heating? #14 Which of the following statements represents acceptable practice for heavy fuel oil storage tank heating? #15 For the most efficient centrifuging of residual fuels on motor vessels, the lower the viscosity of the fuel as achieved by preheating, the more efficiently solids and moisture can be removed. For planning purposes, what is the typically the recommended upper limit of preheating for residual fuel oil centrifugation on motor ships? #16 In new construction or during significant steel plate replacements, what is the procedure of 'line heating'? #17 Vibration analysis can provide comparative data of operating condition of rotating machinery. At what positions should such readings be taken at bearing housings and foundations? #18 While examining vibration analysis of a particular piece of rotating machinery, one of the measurement location readings exhibits high amplitude/displacement in vertical and horizontal direction at 2 X RPM frequency. What would this indicate?
