UK (HIPO)
Incident
In May, a small gas leak occurred when
valve alignment checks were not
completed prior to opening a well on the
Ensco 101 rig in the Southern North Sea
(SNS). The gas detection system activated
a high alarm status immediately, isolating
the leak in less than a minute.
Action
The following updated procedures were
put in place:
• Well schematic sheets stating valve
positions have to be completed at the
start of each shift, and written handover
procedures were put into effect
immediately.
• Valve status sheets were developed and
visual ‘tag’ reminders were placed on
the on control panels to indicate whether
a valve is open or closed.
Excellent safety
performance on complex
operated projects
Pakistan (LTI and HIPO)
Incident
In July, a contractor was splashed with
corrosion inhibitor liquid in the face and
head area when re-installing a pump at
the Suri-1 well in Pakistan. Because he
was wearing safety glasses, rather than
a face shield, the liquid ran down his
forehead into his eyes. He was taken
immediately to the eye wash station,
and then to the field doctor in the on-site
clinic. Fortunately the individual involved
suffered no permanent damage.
Côte d’Ivoire (LTI and HIPO)
Incident
In October, during offshore seismic
acquisition, a contractor was injured when
he was moving a buoy on a seismic
vessel. His hand became trapped between
the buoy, which weighs approximately 90
kg, and the side of the vessel. Fortunately
no bones were broken and no lasting
damage done to the contractor’s hand.
Action
As a result of this incident, hazard
identification was reviewed and further
risk assessment of Suri field operations
was performed with a specific focus on
chemical handling. Formal management
of change procedures were developed by
the EHS manager including job safety
analysis, job risk assessment and
documenting equipment and process
changes. These new procedures have
been implemented by the production
team at the site.
Action
A set of procedures were drawn up to
eliminate the need for manual handling
of buoys, and winches are now used
instead, effectively preventing this type
of incident recurring.
Operations in two countries had
particularly strong safety results.
The Ensco 101 rig, on location at the
Ketch platform in block 44/28 in the
UK SNS, achieved a whole year on
contract to Tullow with no LTIs. In fact,
during the 365,244 hours worked by
the rig during the year there were
no LTIs, no RWDCs or MTCs and just
four First Aid Cases (FAC). This is
a particularly impressive result in
logistically complex operations, as
the rig had been moving between the
Schooner and Ketch fields supporting
combined drilling, well intervention
and production operations throughout
the period.
Our Bangladeshi operations also
achieved a notable performance.
During the last two months of a
seismic acquisition campaign, that
began in 2005, we employed 2,349
personnel and worked in excess of
1.6 million hours without an LTI.
Also, the Bangora production facility
achieved 240 days without an LTI
and the current drilling campaign
in Bangladesh achieved 289 days
without an LTI.
