Thank you for the opportunity to complete a vibration analysis condition monitoring survey. This report contains analysis of the vibration data, including comments and recommendations for corrective action.

Survey information:

Vessel name: GENERAL RUDDER Company: U.S. MARITIME ADMINISTRATION (MARAD) Sign on Port: Galveston, TX Sign off Port: Galveston, TX Data collection start date: Wednesday, April 27th 2022 Data collection end date: Friday, May 13th 2022 Data collected by: PJR and Crew Data collection instrumentation: VA3 - 631712 - PJR, Cal due 2023-04-28 Data collection instrumentation: DC-101058-Rental, Cal due 2023-04-03

Data collection and analysis software: DDS 2022 v 3.6.2.6, CAC Decision Point v5

CAC vibration data collection:

Vibration measurements were obtained in in/sec peak and were taken on each accessible bearing location in three measurement planes. Both overall and vibration signature traces were obtained.

Vibration limit levels:

Measured vibration is compared to vibration limit levels established by CAC's experience with shipboard machinery, as well as ANSI and other standards organizations.

Experienced CAC vibration analysts factored the following:

• Trend analysis

• Readings compared to alarm levels

• Comparison to sister machines and like machinery on sister vessels

• Reported repair history sent to CAC

• Operating conditions.

CAC machine ratings:

This report categorizes machines as follows:

• Unsatisfactory: Machines that require attention.

• Marginal : Machines that are vibrating above initial alarm levels. Increasing wear.

• Satisfactory: Machines operating within acceptable vibration ranges.

• Non-available: Not operating or not safe to take readings.

CAC has the following 'Condition Monitoring' Class certificates:

• ABS Certificate Number 20-4564981-A as a "Recognized External Specialist".

• Lloyds Register Certificate Number LR21116508AS as an "Approved Service Supplier".

CAC maintains all historical data from the vessel. Additional data including vibration signatures and Report Links (PDF) are available on the vessel's home page on the CAC Decision Point ® website at www.cacvibe.net.

DISCLAIMER: CAC assumes no responsibility for machinery failures whatsoever or for any aspect of vessel or machinery operation. Liability is limited to the cost of the service work performed by CAC. CAC service personnel are considered as 'Persons in Addition to the Crew' while onboard. This report is for the use of the client only.

Fwd Draft: 15 Aft Draft: 15 Propeller RPM: 0 Occurs: 1 Comment: Recently replaced with new motor/pump.

Vibration levels have decreased since the August 2021 readings but remain elevated on the pump. Vibration at rotation rate indicates imbalance and misalignment in the pump or coupling. Levels are twice as high in the horizontal direction indicating flexibility in the support skid. Levels are acceptable on the motor.

Recommend Review recent repairs. Inspect foundation, mounting bolts, and support skid.

Evaluate condition of skid mounts. Inspect the coupling and check alignment. If levels persist, replace the pump.

FUEL OIL TRANSFER PUMP MARGINAL

Fwd Draft: 15 Aft Draft: 15 Propeller RPM: 0 Occurs: 1 Vibration levels are over the alarm on the motor and driven end of the pump. Levels are greatest at 3X-motor rotation rate in the axial direction indicating looseness or misalignment. Vibration at 6X-pump rotation rate is likely characteristic and affected by flow. Additional vibration at 35,760 cpm has been seen in the past and is likely gear mesh.

Recommend Inspect foundation and mounting bolts. Inspect motor cooling fan, shaft, and coupling for looseness. Check alignment. Verify gearbox lubrication. If levels persist, service the motor.
