34 fatalities reported by 111 contractors worldwide; LTI rate inches up slightly from 0.37 to 0.38
The drilling industry lost some ground in 2010 when it came to its lost-time incidence (LTI), recordable incidence and fatality rates, according to the newest IADC Incident Statistics Program (ISP) report.
Last year, the industry’s worldwide LTI numbers moved from 2009’s record low of 0.37 up to 0.38, worsening by 3%. The recordables rates moved up from 1.22 to 1.31, which is 7% worse than the 2009 report of 1.22.
The number of fatalities rose from 32 to 34 last year; however, the 2010 fatality incidence rate declined to 0.014, compared with 0.015 in 2009.
Looking at the longer-term trend, the industry’s efforts toward safety have resulted in the occupational LTI rate falling from more than 14.00 in 1963 to 0.38 in 2010, which is a 38-fold improvement.
A total of 111 contractors, representing approximately 78% of the worldwide oil and gas well drilling rig fleet, participated in the 2010 ISP, which has tracked safety and accident information for the drilling industry since 1962. Data here account for 459.391 million manhours worked, during which a total of 846 LTIs and 3,010 recordable incidents were reported.
Incidence rates are calculated on incidents per 200,000 manhours. Data are compiled separately for land and offshore operations and for eight geographic regions — US, Europe, Canada, Africa, Middle East, Asia Pacific, Central America/Caribbean, and South America.
A total of 34 fatalities were reported in 2010; the incidence rate was 0.014, compared with 2009’s 0.015. Employees with one to five years of service with the company accounted for 15 fatalities, the largest percentage. Twelve fatalities occurred to employees who had less than six months of service, and three had between six months and a year of service. Two of the victims had worked for the company between five to 10 years and one victim had worked for the company for 10 years or more.
Five fatalities occurred during rigging up or down operations. Ten of the fatalities involved “struck by” incidents while six involved “caught between” incidents. Eight of the fatalities occurred to floormen; 11 were supervisors of drillers or above.

LTI and recordable incidents by region
One of the best improvements year-on-year was in the offshore LTI rate for the Asia Pacific region, which went down 45% from 0.29 in 2009 to 0.16 in 2010. The region’s recordables rate also improved 20% from 0.84 in 2009 to 0.67 in 2010.
European statistics also saw significant improvement, both onshore and offshore. Land workers saw their LTI rate improve 33% from 0.33 for 2009 to 0.22 for 2010, while their recordables rate improved 34% from 0.47 to 0.31. Offshore, the LTI rate was shaved by 30% from 0.30 to 0.21. Recordable incident rates worsened slightly to 0.74.
In 2009, Middle East land had an LTI rate of 0.23, which improved 22% to 0.18 in 2010. Their 2009 recordable incidence rate of 0.91 improved 5% to 0.86 in 2010. However, offshore the LTI rate worsened 53% from 0.15 in 2009 to 0.23 in 2010 and their recordable incidence rate also worsened 17% from 0.66 in 2009 to 0.77 in 2010.
The Africa onshore LTI rate for 2009 was 0.43, and that improved 9% to 0.39 for 2010 while their recordable incidence rate improved by 23% from 1.50 in 2009 to 1.16 in 2010. Offshore workers in this region saw a worsening in their LTI rate by 25% from 0.20 in 2009 to 0.25 for 2010.

Other ISP findings
- By occupation, the floorman position suffered the largest percentage of injuries, similar to previous years.
- By body part, fingers remained the most vulnerable part of the body.
- By incident type, “caught between” accounted for the most incidents and was closely followed by “struck by” injuries.
- By equipment, pipes/tubulars was the equipment category responsible for the most LTIs and recordable incidents.
- By activity, tripping in/out involved the most lost-time and recordable injuries.
- By location, by far the most injuries in drilling operations occurred on the rig floor.
- By time in service, employees with between one to five years of service had the most LTIs and recordables, followed by employees with six months to one year of service.
- By time of day, the most LTI and recordable incidents occurred between 09:00 to 16:00 hours.
- By month, June accounted for the most LTIs while August accounted for the most recordables.
Incidents occur in many places around the rig and to all crew members. Incident data are analyzed by occupation, body part, incident type, equipment type, operation, location time in service, and time of day the incident occurred.
