In , the company acquired Aker Drilling , which owned 4 harsh environment rigs used for drilling near Norway. In , the company sold 38 shallow water rigs and narrowed its focus on high-specification deepwater rigs.
Transocean was rated as a leader in its industry for many years. However, since the company's merger with GlobalSantaFe in , Transocean's reputation has suffered considerably, according to EnergyPoint Research, an independent oil service industry rating firm.
From to , Transocean was the leader or near the top among deep-water drillers in "job quality" and "overall satisfaction. On March 2, , a Scottish man was killed in an accident aboard the Transocean Leader drilling rig operated for BP , located about kilometers 86 miles west of Shetland , Scotland.
On June 17, , one worker was killed, four others were hospitalised and 21 were evacuated after an explosion on a Transocean gas drilling rig in Galveston Bay, Texas.

As the Deepwater Horizon sank, the riser pipe that connected the well-head to the rig was severed. As a result, oil began to spill into the Gulf of Mexico. Estimates of the leak were about 80, barrels per day — for 87 days. Louisiana Governor Bobby Jindal declared a state of emergency on April 29, as the oil slick grew and headed toward the most important and most sensitive wetlands in North America, threatening to destroy wildlife and the livelihood of thousands of fishermen.
During Congressional testimony, Transocean and BP blamed each other for the disaster. The American people could not have been impressed with that display, and I certainly wasn't. In a regulatory filing, Transocean said, "Notwithstanding the tragic loss of life in the Gulf of Mexico, we achieved an exemplary statistical safety record as measured by our total recordable incident rate and total potential severity rate.
The offshore drilling facility "Sedco ", operated by Transocean under contract from Chevron , began to leak in November while working on the "Frade" oil field.
The Brazilian government sued Transocean and attempted to force the company to cease operations in Brazil, but a settlement was reached without a finding of fault or liability.
The rig subsequently drifted ashore at Dalmore and became stuck fast on rocks at Continuing poor weather meant that a damage inspection by salvors has been practically impossible, as personnel require to be airlifted on to the rig, in spite of it being close to the shore. In early April , six activists with the environmental group Greenpeace boarded the ship Blue Marlin while at sea, which was carrying one of Transocean's rigs, the meter ft.
The activists promised to continuing their protests as the rig undergoes final outfitting while it is anchored in the Port Angeles harbor in Washington State and then later in Puget Sound.
