About this file
This document is a Test, Adjust and Balance (TAB) report for pneumatic control system replacements aboard the dredge Yaquina. The report details TAB work performed by MacDonald Miller Facility Solutions under job number 7322-3965. TAB procedures were conducted in accordance with NEBB standards on various dual duct box air distribution units serving over 30 zones. Test data is provided for both cooling and heating modes, including supply air flow measurements and temperatures. Measured data is noted as a percentage of design air flows. Most units measured between 30-80% of design air flow values, with some higher. The report includes instrumentation calibration records and generic schematics but no system design drawings.
The related federal contract opportunity is a solicitation from the US Army Corps of Engineers Portland District for the FY24 overhaul of the dredge Yaquina. The solicitation number is W9127N23B0014 but no further details are provided in the document.

EXECUTIVE SUMMARY
I. GENERAL NOTES
A. TAB completion date: 02/28/2023
B. Design information was provided from original mechanical drawings, or they were field engineered.
C. TAB work was in accordance with the most current version of NEBB procedural standards for Testing
Adjusting and Balancing.
D. Methods of measurements: All measurements were taken with appropriate instruments based on the standards referenced above and comparable to the list of calibrated instruments listed in calibration report of this report.
E. Basic “not to scale” drawings with device and outlet numbering are included in Appendix of this report.
F. Motors of fans which did not list pF (power factor) or Eff (efficiency) ratings on their nameplate had it’s associated fan’s BHP (Brake Horsepower) approximated by using a nominal 0.9 pF and 0.8 Eff in the BHP calculation. Actual BHP's may vary slightly in this condition.
II. SCOPE OF WORK
A. Various pneumatic piston actuators were replaced, along with pneumatic thermostats, throughout the ship. All work was the test and balance each piece of equipment which was replaced.
III. DESCRIPTION OF THE SYSTEMS BALANCED
A. For each unit a pneumatic actuator moves a damper which modulates between cold deck ductwork and hot deck ductwork. This piston’s control signal comes from a thermostat located in each zone. There are no balancing dampers present on any of the pneumatic boxes.
IV. TAB PROCEDURES SUMMARIZED – AIR SYSTEM TESTING PROCEDURES
A. The zone was placed into full cooling by turning the thermostat to the lowest setting, which was 55 F.
B. The discharge air volume and temperature were read and recorded.
C. The unit was placed into full heating by turning the thermostat to the highest setting, which was 85 F.
D. The discharge air volume and temperature were read and recorded.
V. OTHER MISCELLANEOUS NOTES
A. Because the scope was limited to testing of the replaced elements of the system and there were components on the system which were not worked on, compounded by the issue of not dampers being found to further balance the system, the numbers recorded were marked as final. Any low readings were left as is because the balance of the entire system was out of scope and no action could be taken.
