Numbers from the latest IADC Incident Statistics Program (ISP) are encouraging. The ISP, which has tracked safety and accident information for the drilling industry since 1962, shows that the worldwide lost-time incidents (LTI) rate improved by 27.7% from 2015 to 2016, going from 0.18 to 0.13. The recordable incident rate also saw improvement, falling by 23.3% from 0.60 in 2015 to 0.46 in 2016.
“The drilling industry’s efforts toward safety have resulted in the industry’s occupational LTI incidence rate to improve from more than 14.00 in 1963 to 0.13 in 2016, which is a 107-fold improvement,” said Rhett Winter, IADC’s Director of Onshore Operations.
Although the industry saw fewer LTI and recordable incidents in 2016, fatalities increased slightly, from eight in 2015 to nine in 2016.
The ISP report is based on incident rates, which are calculated on incidents per 200,000 man-hours. During 2016, 95 contractors participated in the ISP. These contractors worked a total of 396.2 million man-hours, compared with 500.6 million man-hours worked in 2015. In total, these companies reported 909 recordable incidents and 254 LTIs.
Out of the nine fatalities that were reported in 2016, four involved employees with more than one but fewer than five years of service. Two of the fatalities occurred during rigging up or rigging down operations, with additional fatalities occurring during riser handling, equipment maintenance, mud mixing/pumping, BOP stack installation or maintenance, casing or tubular running, and well testing. Eight of the fatalities were “struck-by” incidents, and one was a “caught-between” incident. By occupation, Drillers and Assistant Drillers accounted for four of the nine fatalities.
Together, US land and offshore contractors worked 62 million man-hours with four fatalities.
Three of these fatalities occurred onshore, where contractors worked a total of 34 million man-hours. The LTI rate for US onshore worsened in 2016, rising by 12.9% from 0.31 in 2015 to 0.35. US onshore contractors saw a small improvement in their recordable incidence rate, which fell by 1.6% from 1.22 in 2015 to 1.20 in 2016.
Offshore contractors logged 27.8 million man-hours and had one fatality. The LTI rate for US offshore is down by 25% from 2015, falling from a rate of 0.12 to 0.09. The total recordable incident rate also improved from 0.56 in 2015 to 0.49 in 2016, which is a decrease of 12.5%.
Drilling contractors in Europe worked a total of 68 million man-hours in 2016 with one fatality, which occurred onshore.
Onshore contractors worked 40.2 million man-hours in 2016. They saw their LTI rate increase by 13.3%, from 0.15 in 2015 to 0.17 in 2016. The recordable rate remained steady at 0.23.
Offshore Europe accounted for 28.5 million man-hours worked and no fatalities. The LTI rate improved by 36.8%, from 0.19 in 2015 to 0.12 in 2016. Recordable incident rates also improved, decreasing by 20.6% from 0.63 in 2015 to 0.50 in 2016.
Canadian contractors worked 2.29 million man-hours in 2016 with no fatalities.
Onshore contractors in the region accounted for 746,000 man-hours. Their LTI rate rose significantly, from 0.14 in 2015 to 0.54 in 2016, which is an increase of 285.7%. Their recordable incident rate improved slightly from 1.36 to 1.34, for a 1.5% reduction.
Offshore contractors in the region fared better. They worked 1.5 million man-hours and held their LTI rate steady at zero. The recordable incident rate for Canadian offshore improved by 67.5%, from 0.80 in 2015 to 0.26 in 2016.

Contractors in Central America and the Caribbean worked a total of 4.7 million man-hours with no fatalities.
Onshore contractors logged 1 million man-hours and lowered their LTI rate by 43.9%, from 0.98 in 2015 to 0.55 in 2016. The recordable incident rate for the region’s contractors worsened slightly. It rose from a rate of 1.59 in 2015 to 1.64 in 2016, for a 3.1% increase.
Offshore, drilling contractors in Central America and the Caribbean worked just over 3.6 million man-hours. Their 2015 LTI rate of 0.18 fell by 38.9% to 0.11 in 2016. The recordable rate in the region also improved, dropping by 45.9% from 0.61 in 2015 to 0.33 in 2016.

Onshore contractors accounted for 17.9 million man-hours and saw notable improvements to both their LTI and recordable rates. The LTI rate improved by 71.8%, from a 2015 rate of 0.39 to a 2016 rate of 0.11. Similarly, the recordable incident rate improved by 66.4%, falling from 1.16 in 2015 to 0.39 in 2016.
