In the near term, there will be shortage of rigs in the mid-water, deepwater, and ultra-deepwater markets. Over the long term, there will be a significant number of new rigs coming out in 2014, and the market could come back in line, said Mike Acuff , senior vice president, contracts and marketing, Diamond Offshore Drilling Inc.

Speaking at the IADC 2012 annual meeting in Scottsdale, Ariz., Nov. 8, Acuff pointed out that the rigs for ultra-deepwater, which is >2,272 m (>7,500 ft) and deepwater, which is 1,515 m to 2,272 m (5,000 ft to 7,500 ft), are “sold out in effect for 2013. The first available rigs will be in 2014.  Operators are lining up for rig capacity.”

A year ago, day rates were in the US $300,000 range. In the past 12 months, those rates have gone up to $500,000 per day, and availability in 2013 is difficult, he emphasized. However, at the same time, costs have gone up for labor and equipment, “so it is not a one-for-one increase for the day rates.”

The number of rigs under construction is almost at the peak level reached in 2008. Newbuilds have gone up for two reasons – higher demand and attractive shipyard pricing in Singapore and South Korea, he continued.

Currently, demand for ultra-deepwater (UDW) and deepwater rigs are being driven by exploration work. There will be an even greater demand for these rigs when development drilling begins in many of these frontier areas, Acuff said.

Mid-water, deepwater niche market

The number of rigs available for the mid-water market (152 m to 1,515 m or 500 ft to 5,000 ft) has remained steady over the past few years, he noted.

Diamond Offshore sees a niche market for mid-water and deepwater rigs. The company is converting two older semisubmersibles for water depths to 1,818 m (6,000 ft). The Onyx is being converted in Brownsville, Texas, and the Apex in the Jurong Shipyard in Singapore. By reusing the hulls, the price tags for the conversions are much lower – $300 million for the former and $370 million for the latter.

“We see this as a significant market going forward, he added.

Three major challenges

Although the UDW and deepwater markets are attractive, there are three major challenges facing the industry – personnel, training and competency, and regulatory uncertainty.

Finding crews for the newbuilds is a significant challenge for Diamond Offshore and
