Operating expenses increased by $1.2 million, or 7%, from the prior year quarter due primarily to higher repair and maintenance costs. For the six months ended June 30, 2002, revenues for the Europe jackup rigs increased by $13.1 million, or 19%, and the operating margin increased by $11.7 million, or 32%, from the prior year period. The increase in revenues and operating margin is primarily attributable to a 34% increase in average day rates, partially offset by lower utilization, which decreased to 74% in the current year period from 84% in the prior year period. Operating expenses increased by $1.4 million, or 4%, from the prior year period due primarily to higher repair and maintenance costs. Asia Pacific Jackup Rigs Second quarter 2002 revenues for the Asia Pacific jackup rigs increased by $12.6 million, or 50%, and operating margin increased by $10.4 million, or 80%, from the prior year quarter. The increase in revenues and operating margin is primarily due to higher average day rates, which increased 45% from the prior year quarter, and the addition of the ENSCO 94 to the Asia Pacific jackup rig fleet which commenced drilling operations in the first quarter of 2002 after mobilization from the Gulf of Mexico, partially offset by a decrease in utilization, to 72% in the current year quarter from 100% in the prior year quarter. Operating expenses increased by $2.2 million, or 18%, in the current year quarter due primarily to the addition of the ENSCO 94 to the Asia Pacific fleet in the current year quarter. For the six months ended June 30, 2002, revenues for the Asia Pacific jackup rigs increased by $32.7 million, or 72%, and the operating margin increased by $24.0 million, or 110%, from the prior year period. These increases are due primarily to higher average day rates, which increased 49% from the prior year period, and the addition of the ENSCO 94 to the Asia Pacific jackup rig fleet, which commenced drilling operations in the first quarter of 2002 after mobilization from the Gulf of Mexico. During the first quarter of 2002, the Company also mobilized the ENSCO 51 and ENSCO 54 from the Gulf of Mexico to a shipyard in Singapore. Both rigs remained in the shipyard through June 30, 2002 undergoing enhancement and repair work. Operating expenses increased by $8.7 million, or 37%, in the current year period primarily due to rig mobilization and other operating costs associated with the ENSCO 54 and ENSCO 94 in the current year period. North America Semisubmersible Rig Second quarter 2002 revenues from the ENSCO 7500 increased by $100,000, or 1%, and operating margin decreased $100,000, or 1%, as compared to the prior year quarter. Second quarter 2002 operating expenses related to the ENSCO 7500 increased $200,000, or 5%, as compared to the prior year quarter. The increase in operating expenses, and decrease in operating margin, is due primarily to an increase in repair and maintenance expenses. For the six months ended June 30, 2002 revenues for the ENSCO 7500 decreased by $1.4 million, or 5%, and operating margin decreased by $4.2, or 21%, from the prior year period. The decrease in revenue and operating margin is due to rig down time during the first quarter of 2002 to undergo rig hull repairs. Operating expenses increased $2.8 million, or 33%, from the prior year period due primarily to costs related to the aforementioned repairs in the first quarter of 2002. South America Barge Rigs Second quarter 2002 revenues for the South America barge rigs decreased by $8.5 million, or 66%, and operating margin decreased by $4.6 million, or 87%, from the prior year quarter. The decrease in revenues and operating margin as compared to the prior year quarter is due primarily to lower utilization, as only one barge rig was fully utilized in the current year quarter compared to three barge rigs fully utilized in the year earlier quarter. In September and November of 2001, a customer elected to terminate two long-term contracts after approximately half of the respective five-year contract terms had been completed. The terminations resulted from the customer's disappointing oil production rates from the reservoir and the ensuing reduction in their drilling plans, and were not due to any fault with the Company's drilling rigs. Operating expenses decreased $3.9 million, or 51%, due primarily to the decrease in utilization. For the six months ended June 30, 2002, revenues for the South America barge rigs decreased by $16.6 million, or 66%, and operating margin decreased by $9.1 million, or 89%, from the prior year period. The decrease in revenues and operating margin as compared to the prior year period is due primarily to lower utilization, as only one barge rig was fully utilized in the current year period compared to three barge rigs fully utilized in the prior year period. Operating expenses decreased $7.5 million, or 50%, due primarily to the decrease in utilization. Platform Rigs Second quarter 2002 revenues for the platform rigs decreased by $4.9 million, or 50%, and operating margin decreased by $1.9 million, or 54%, as compared to the prior year quarter. The decrease in revenues and operating margin is primarily due to two rigs, one of which was idle during the current year quarter compared to fully utilized during the year earlier quarter and the second of which earned a minor standby rate during the current year quarter compared to earning full day rate in the year earlier quarter. Operating expenses decreased by $3.0 million, or 48%, from the prior year quarter primarily due to the two rigs discussed above. For the six months ended June 30, 2002, revenues for the platform rigs decreased by $10.0 million, or 51%, and operating margin decreased by $4.6 million, or 64%, from the prior year period.
