1. An Arrangement in an offshore production platform comprising:
- (a) a deck positioned above the surface of the water and having at least one pair of spaced-apart rails thereon;
(b) drilling means mounted on the spaced apart rails and adapted to move along the rails between different locations on the deck;
(c) a truss tower mounted to the sea floor for supporting the deck, said truss tower comprising at least two pairs of opposed legs connected to the deck at one end and connected in at least one location along their length by two orthogonally intersecting support means, wherein the rails of the deck are parallel to one of the support means; and

Abstract
A production platform for offshore exploitation of hydrocarbons comprises a truss tower (1) which rests on the sea floor (2) and supports a deck structure (3) provided with a drilling module (5). In order to obtain optimum mutual distance between production pipes (10) at the deck level, the skid beams (6) of the drilling module are arranged parallel to a diagonal (9) in the cross-section of the truss tower. Weight savings in the truss tower (1) may be obtained by arranging the deck structure (3) with its sides parallel to the diagonals (9) of the truss tower (1).
