Petroleum (Submerged Lands) Act 1982

For the purposes of this Act, the surface of the Earth shall be deemed to be divided—

by the meridian of Greenwich and by meridians that are at a distance from that meridian of five minutes, or a multiple of five minutes, of longitude; and

by the equator and by parallels of latitude that are at a distance from the equator of five minutes, or a multiple of five minutes, of latitude, into sections, each of which is bounded—

by portions of two of those meridians that are at a distance from each other of five minutes of longitude; and

by portions of two of those parallels of latitude that are at a distance from each other of five minutes of latitude.

For the purposes of this Act—

a graticular section that is wholly within the adjacent area constitutes a block; and

if a part only of a graticular section is, or parts only of a graticular section are, within the adjacent area, the area of that part, or of those parts, constitutes a block.

In this Act—

a reference to a block that is constituted by a graticular section includes a reference to a block that is constituted by the area of a part only, or by the areas of parts only, of a graticular section; and

a reference to a graticular section that constitutes a block includes a reference to a graticular section part only of which constitutes, or parts only of which constitute, a block.
