## Abstract

A tank subjected to thermal expansion and contraction, comprising a support block in contact with the bottom of the tank, where the support block and the bottom of the tank are connected by a rib in either the bottom of the tank or the support block, where the rib is in a groove in either the bottom of the tank or the support block to prevent horizontal movement of the tank.

## Claims

### Claim 1

A tank subjected to thermal expansion and contraction comprising a support arranged at the bottom of the tank, the support comprising a support block in contact with the bottom of the tank, movement prevention means for preventing movement of the tank with respect to said support block in a horizontal direction, said movement prevention means comprising a rib arranged in either said bottom of the tank or said support block, and a corresponding groove in the other of said bottom of the tank or said support block, wherein the bottom of the tank comprises first and second elements joined together by welds, whereof the first element rests on said support block and comprises said rib or said groove spaced from said welds by which the first element is joined to a pair of adjoining second elements.

### Claim 2 (depends on 1)

The tank according to claim 1, wherein said rib is depending from said first element and is extending into the corresponding groove in said support block.

### Claim 3 (depends on 1)

The tank according to claim 1, wherein said rib is extending from said support block into said groove in said first element.

### Claim 4 (depends on 1)

The tank according to claim 1, wherein said rib or said groove is equally spaced from said welds to said adjoining second elements of the tank.

### Claim 5 (depends on 1)

The tank according to claim 1, wherein said rib is a rolled or extruded part of said first element of the bottom of the tank.
