A close tolerance pin connection includes a cylindrical connecting pin. A first sturcture has a first pin receiving hole disposed therethrough for closely receiving the connecting pin. A second structure has a second pin receiving hole disposed therethrough for loosely receiving the connecting pin. A weld washer has a third pin receiving hole disposed therethrough for closely receiving the connecting pin, and the weld washer is adapted to be located adjacent and engage the second structure. The connecing pin is received in the first, second and third pin receiving holes and the weld washer is then welded to the second structure so that the first and second structures are connected by the connecting pin. The connecting pin is closely received within the first hole of the first structure and is also closely received in the third hole of the weld washer which is fixed to the second structure, thus providing a close tolerance pin connection between the first and second structures after the weld washer is welded to the second structure.

Close tolerance pin connection

A grid system for supporting a plurality of items of equipment from a deck of a floating vessel includes a plurality of brackets welded to the deck. A support grid for supporting the plurality of items of equipment above the deck includes a plurality of interconnected substantially horizontally oriented beams. The support grid spreads the weight of each of the items of equipment over a larger area of the deck than it would be if each item was directly supported from the deck. A plurality of detachable connecting pin assemblies are provided for detachably connecting the support grid to the plurality of brackets, so that the support grid can be attached to the plurality of brackets without the need for welding to the deck after the plurality of brackets have been previously been welded to the deck. Equipment mounting brackets are operably associated with the support grid for mounting the plurality of items of equipment above the support grid with similar connecting pin assemblies.
