For 2013, drilling contractors reported 2,386 recordable incidents, 743 lost-time incidents and 22 fatalities. Seven fatalities were struck-by incidents, while five were due to fall-type incidents.

For 2013, drilling contractors reported 2,386 recordable incidents, 743 lost-time incidents and 22 fatalities. Seven fatalities were struck-by incidents, while five were due to fall-type incidents.

The global drilling industry saw its lost-time incidence (LTI) rate and its number of fatalities unchanged from 2012 to 2013, at 0.26 and 22 fatalities, respectively. Improvements were visible in the 2013 total recordable incidence rate (TRIR), which improved by 8% from 0.88 to 0.81. “Activity in most sectors of the industry decreased in 2013,” Paul Breaux, IADC Director Onshore HSE, said. “Although the number of fatalities remained the same as the previous year, the overall incidence and frequency rates are still trending downward even as manhours continue to trend upward.”

Rates in this report are calculated based on incidence rates, which are calculated based on incidents per 200,000 manhours.

The IADC Incident Statistics Program (ISP) compiles data submitted voluntarily from drilling contractors. In 2013, 108 contractors participated in the ISP, representing a total of 592 million manhours worked. These companies reported a total of 2,386 recordable incidents, 743 LTIs and 22 fatalities.

By occupation, the largest percentage of LTIs and recordables happened to floormen.

In 2014, the ISP has been expanded to include well-servicing contractors; results being collected this year will be available in next year’s report. “IADC urges participation in the ISP by every drilling and well-servicing contractor around the world. Additional data would give us an even clearer picture of safety trends occurring in the industry,” Mr Breaux said. To participate, send an email to isp@iadc.org.

Fatalities

Statistics show that fingers are still the most vulnerable part of the body, followed feet/ankles for LTIs and head/face for recordables.

Statistics show that fingers are still the most vulnerable part of the body, followed feet/ankles for LTIs and head/face for recordables.

By years of service, the breakdown of fatalities is:

• 10 or more years: seven fatalities;

•5-10 years: two fatalities;

•1-5 years: five fatalities;

•6 months to 1 year: two fatalities;

•3-6 months: four fatalities.

Time in service was not reported for the remaining two fatalities.

Similar to last year’s report, caught-between incidents were the most common and were closely followed by struck-by incidents.

Three of the fatalities occurred during a well control event and three during routine drilling operations. Seven fatalities were struck-by incidents, while five were due to fall-type incidents. Five of the fatalities occurred to floormen, and five fatalities occurred to motormen.
