LOC400 brochure - Huisman-Itrec - #5

Statistics show that pipe and material handling cause almost 50% of the recorded accidents during well drilling. The fully automated pipe han­dling of the LOC400, with its automated drill floor, obviates the need for personnel on the drill floor and thus eliminates the potential for accidents. In addition, the simple rig-assembly process - smaller loads, less rig crew involvement and improved overview and visibility - effective­ly mitigates the risk for the crew and the potential for accidents and dam-

The LOC400 has a significantly lower adverse impact on the environment when compared with conventional rigs. Because drilling a well with the LOC400 requires less drilling time and lower mud pump pressures and flow rates, two 800-hp mud pumps are sufficient, compared with the three 1000-hp pumps required for conventional DP drilling. This means a 45% lower fuel consumption per day of drilling and a reduction in hydrocarbon emissions per well of up to 75%.

Mud and cement costs are reduced by 10 to 20%. Because the LOC400 has only a single 38-m mast, its silhouette does not impact significantly on the horizon. The footprint of the LOC400, at 700 m2, is 75% smaller than the 3000 m2 required for a conventional rig.

Many conventional rigs are combinations of components and subsystems developed and maintained by different suppliers. The LOC400, however, is a fully integrated, operational drilling rig that is offered as a complete package. All the components, including drawworks, top drive, mud pumps, power unit, mud system, BOPs and an integrated control and monitoring system, have been carefully selected and tested to ensure balanced and trouble-free operation. A complete and integrated Geolograph is also included. The monitoring system includes satellite-linked remote diagnosis and troubleshooting, which enables Huisman engineers to help customers to solve any problems.

Each LOC400 is customized to meet the customer's specific needs and is fully tested and commissioned before delivery. Additional modules such as extra mud tanks or mud pumps can be installed on request.
