Irregular Buildings

Turning Torso is based on a sculpture by Calatrava, called Twisting Torso, which is a white marble piece based on the form of a twisting human being.

In 1999, HSB Malmö's former managing director, Johnny Ö rbäck, saw the sculpture in a brochure presenting Calatrava in connection with his contribution to the architectural competition for the Ö resund Bridge. It was on this occasion that Ö rbäck was inspired to build HSB Turning Torso. Shortly afterwards he travelled to Zurich to meet Calatrava, and ask him to design a residential building based on the idea of a structure of twisting cubes.

Twisted Shell Member Analysis

In its geometric essence, shape from texture is a cue to 3D shapevery similar to binocular stereopsis and structure from motion.

All of these cues are based on the information available inmultiple perspective views of the same surface in the scene.

In binocular stereopsis, the two eyes get slightly different views of the same surface; in structure from motion, the relative motionof the observer and the surface generates the different views.

Refinery Frame

An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene and liquefied petroleum gas.

Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units.

In many ways, oil refineries use much of the technology of, and can be thought of, as types of chemical plants. The crude oil feedstock has typically been processed by an oil production plant.

There is usually an oil depot (tank farm) at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products.

Ball Tank

This type of storage vessel is preferred for storage of high pressure fluids. A sphere is a very strong structure. The even distribution of stresses on the sphere's surfaces, both internally and externally, generally means that there are no weak points. Spheres however, are much more costly to manufacture than cylindrical or rectangular vessels.

Storage Spheres need ancillary equipment similar to tank storage - e.g. Access manholes, Safety valves, Access ladders, Earthing points .. etc.

An advantage of spherical storage vessels is, that they have a smaller surface area per unit volume than any other shape of vessel. This means, that the quantity of heat transferred from warmer surroundings to the liquid in the sphere, will be less than that for cylindrical or rectangular storage vessels.
