Singapore Changi International Airport

Singapore Changi International Airport
Phases of construction for 26 new aircraft parking stands and layout of a MARS stand showing A380 aircraft in position, hydrant pits and stopbars for other aircraft.

eJet were appointed as Aviation Fuel consultant to the aviation fuel farm and hydrant system operator for the development of hydrant fuelling on several different areas of the airport.

10 New Aircraft Stands on Two Cargo Aprons

Eight of the stands are on new pavement and comprise parking for many different types of aircraft on the various centrelines. Of these, six of the stands are able to accommodate up to Code E (B747-400 size) aircraft. The remaining two stands are able to accommodate up to Code F (A380 size) aircraft, but also have offset centrelines to allow two Code C (B737/A320 size) aircraft to park simultaneously in MARS (Multi Aircraft Ramp System) configuration. Similar design requirements applied to two other stands on another, existing, cargo apron (although the
tie-ins on one of those stands required hot works).

MARS parking configurations bring additional complexity to hydrant design because many more variables have to be dealt with on one parking area. Nevertheless, eJet were wellplaced and eminently qualified to do this work because of previous credentials with the design and construction of MARS parking at Delhi and Hong Kong, and John Pitts’ earlier design experience of econfiguring stands at London Gatwick in the early/mid 1990’s for MARS parking when it was a relatively new concept.

The assignment required an extensive refuelling study in order to optimise hydrant pit positions and the routing of the new hydrant lines. eJet also advised on materials procurement and the form of construction contract, and had an on-going involvement in the project as it progressed through construction and commissioning.

3 New Aircraft Parking Stands

eJet were appointed as Aviation Fuel consultant to the aviation fuel farm and hydrant system operator for the development of hydrant fuelling on 3 new aircraft stands at the Former Budget Terminal.

This work involved the extension of the existing DN450 (18 inch diameter) hydrant line under 3 new stands for Code C aircraft, and the provision of hydrant pits to serve these aircraft.

26 New Aircraft Parking Stands

eJet were appointed as Aviation Fuel consultant to the aviation fuel farm and hydrant system operator for the development of hydrant fuelling on 26 new aircraft stands
at South End Reservoir for Terminal 4.

This was a major piece of work and involved the design and construction tender preparation for the extension of the existing DN450 (18 inch diameter) hydrant line under 9 dedicated widebody aircraft parking stands, 17 dedicated Code C aircraft parking stands, and numerous flexible Code C aircraft parking stands on the widebody aprons (MARS).

In addition to the complexity of the design for the MARS concept, in order to keep pace with the airport authority programme for construction of the relevant apron areas in phases, the project was fast-track. The client was cautious to ensure that the consultant appointed would be able to deliver the design within a short timeframe, and this was one of the key reasons why eJet was appointed.
