Abstract

Drilling equipment, especially for offshore use, has a drilling floor or platform 11 with a derrick 10 extending upwards therefrom. A first hoist 12 connected to the top part of the derrick is used for passing a length of tube 19, such as a drill string or a well casing, through a drilling opening 18 defined in and extending through the drilling floor. The length of tube is connected to or disconnected from the drill string or well casing during the drilling operation, and such lengths of tube are stored in a storage area 31, 32 of the drilling floor. The lengths of tube may be transported from the storage area to the first hoist 12 and vice versa by means of first transporting means 22. The drilling floor or platform 11 also defines a preparation opening 21 extending therethrough at a location spaced from the drilling opening and from the storage area, and a second hoist or a preparation hoist 20 is connected to the top part of the derrick above the preparation opening. Two or more tubular sections may then be assembled to form lengths of tube at the preparation opening by means of the preparation hoist while the drilling operation is going on at the drilling opening, and the prepared lengths of tube may be transported to and stored in the storage area ready for use at the drilling opening. Similarly, lengths of tube may be disassembled into tubular sections at the preparation opening before they are transported from the drilling site. The possibility of assembling tubular sections to form lengths of tube and disassembling tubular lengths into tubular sections at the preparation opening while the drilling operation is going on at the drilling opening substantially reduces the necessary idle time in drilling operations. <IMAGE>
