Faculty of Infrastructure, Energy and Industry

Lifelines fail in chains: a substation trips, pumps stop, a port closes, a supply chain stalls.

Departments and their disciplines

Numbered as on the faculty figure above.

03Disciplines

Disciplines of the faculty

Each discipline once, in its department.

04Teaching model

The faculty's teaching model

The model every discipline of the faculty builds on, as a chain you can run: set its parameters, play its steps, read each citation.

05Maps

Build a twin of any place

Search any place or open the world; the layers and generators follow the faculty's subjects on the planet map, the globe and in 3D.

Wellington and its harbour, New Zealand. Flat plan of the same data. The 3D twin opens on devices with WebGL once its data and library have been checked; the numbers are the same either way.

Terrain 0 to 523 m
83,815 buildings in the box
5,085 footprints in the core, 2,796 with an estimated height
Roads 176 km
Rail 99 km
57 substations
4 port
2 airport
5 hospitals
8 railway stations
4 water works
2 power plants, 202 MW

Credits and dates per layer are listed under the stage. Relief in the twin is exaggerated ×1.5 for legibility.

Drag to move, right drag or Shift with a drag to turn and tilt, Ctrl with the wheel to zoom. Keyboard: arrows move, Shift with arrows turn and tilt, + and - zoom, 0 resets, V steps through the views, Escape clears.

Lifeline dependency graph

Which lifeline depends on which: the supply links declared in the twin's lifelines file, drawn as a graph you can read node by node.

National grid supply supplies Wilton substation 220 kV
West Wind wind farm supplies Wilton substation 220 kV
Wilton substation 220 kV supplies Central Park substation 110 kV
Wilton substation 220 kV supplies Kaiwharawhara substation 110 kV
Central Park substation 110 kV supplies Water supply (24 h buffer)
Central Park substation 110 kV supplies Wastewater treatment (2 h buffer)
Central Park substation 110 kV supplies Telecommunications (6 h buffer)
Central Park substation 110 kV supplies Rail traction
Kaiwharawhara substation 110 kV supplies Rail traction
Central Park substation 110 kV supplies Traffic signals
Central Park substation 110 kV supplies CentrePort (1 h buffer)
Kaiwharawhara substation 110 kV supplies Wellington Airport (2 h buffer)
Telecommunications supplies CentrePort (4 h buffer)
Central Park substation 110 kV supplies Wellington Regional Hospital (48 h buffer)
Water supply supplies Wellington Regional Hospital (12 h buffer)
Telecommunications supplies Emergency dispatch (2 h buffer)
Central Park substation 110 kV supplies Emergency dispatch (24 h buffer)

A teaching model declared by hand from the lifeline families present in the twin; it is not an operator's dependency register.

Outage cascade simulator

Cut one lifeline and watch the loss propagate along the declared dependencies, step by step, with the services lost at each step.

Cut: Central Park substation 110 kV 7 dependent lifelines fail within 36 hours (teaching model, not a prediction).

When	Lifeline	Service lost
Cut	Central Park substation 110 kV	Distribution to the central city and the southern suburbs
Cut	Traffic signals	Signalled junctions on the arterial roads
+1 h	CentrePort	Container and log terminals, ferry berths
+2 h	Wastewater treatment	Pumping and treatment at Moa Point
+6 h	Telecommunications	Exchanges and mobile sites on battery backup
+8 h	Emergency dispatch	Call taking and dispatch for fire, police and ambulance
+24 h	Water supply	Pumped supply to reservoirs and the city network
+36 h	Wellington Regional Hospital	Acute care on generators, then on water

Propagation is computed in your browser from the declared links and their delays; a teaching model, not a prediction of any real outage. Buffers (hours before a dependent fails) are teaching values, stated here: 48 hours of hospital generator fuel, 24 hours of reservoir storage for the water supply, 24 hours of generator fuel at emergency dispatch, 6 hours of exchange batteries, 4 hours for port systems on telecommunications, 2 hours of airport generators, 2 hours of wastewater pumping storage, 1 hour of port generators and no buffer for rail traction and traffic signals. Illustrative values for teaching, not measured.
