Case study: Addition of Aircraft Gate Utilities (400 Hz, Potable Water)

Ports

Addition of Aircraft Gate Utilities (400 Hz, Potable Water)

Customer: Port of Seattle

Project Location:Seattle, Washington

At the Seattle-Tacoma International Airport, there were varying amenities at the passenger loading bridges on the North and South Satellites, and Concourses A, B, C & D, including 400Hz ground power supply, potable water, pre-conditioned air, and Safedock aircraft guidance and parking systems. The Port determined that they needed to upgrade all gates with a minimum of potable water and 400Hz power. This required a new centralized 400Hz generation and distribution system at Concourse B and at the South Satellite. Each of the two new 400Hz generation systems included two parallel 400KVA motor-generator sets with a common distribution panelboard. To accommodate all the gates identified by the Port with potable water an entire new header at both the North and South Satellites, and an extension of the existing concourse B header was required.

The Challenge

This project was spread across a majority of the Airport terminals and a majority of the new equipment would be located on the aircraft operations area (AOA). The project design, therefore, required a significant amount of coordination with a large number of Port stakeholders.

The Port wanted to reuse as much of the existing equipment as possible, which included 400Hz gate boxes, disconnects, pantographs, cable hoists, control stations, aircraft cables, and potable water cabinets.

The Solution

To ensure all applicable stakeholders were included in the design process the typical project design reviews were further enhanced with additional meetings, field walk through and incremental review of specific design aspects as they were developed.

Each piece of equipment was inspected and assessed for reuse based on age, condition, and its ability to work within the new systems.

The Benefits

The upfront field investigation performed by Harris Group design team allowed the design to maximize the use of existing equipment, avoid potential asbestos abatement areas that would have increased cost, allow pre-purchase of major equipment and contributed to the accuracy of the design documents. Close coordination and interaction with operations during the design, over and above the normal review process, allowed their needs and concerns to be identified and clearly defined. As a full service engineering company Harris Group was able to reduce cost and increase design coordination by provided the electrical, mechanical, structural and architectural design required for this project with in-house staff.
