Update to
Finds and Recommendations of the
Crane Accident Workgroup
In
October 1998, the Bureau issued a
report on 34 crane incidents that occurred in the period of 1995 to October
1998. In that report, the crane workgroup made five recommendations for
improving the safety of crane operations. This update discusses the actions
taken on those five recommendations in the past year as well as lists the
crane incidents that have occurred since September 1998.
Recommendations from Workgroup
Request
API to revise API RP 2D. As a result of the Report, the Bureau requested API to revise API RP 2D, Third
Edition, June 1, 1995,
Recommended Practice for Operation and Maintenance of Offshore Cranes, (a
document currently incorporated into our regulations) to include rigger
training. API formed a work group, which included an Bureau representative, and
revised the document.
In
March 2000, the Bureau published a technical amendment (65 FR 15862) to update and
reaffirm various documents incorporated by reference under section 30 CFR
250.198. These included Bureau inspection criteria for cranes and other
material handling equipment, and for the training of riggers, crane
operators, and inspectors according to the American Petroleum Institute
(API) Recommended Practice (RP) 2D, Fourth Edition.
On April 1, 2001,
MMS started checking for compliance with rigger training requirement
according to API RP 2D, Fourth Edition.
When this page was
last updated in 1999 MMS was considering the possible incorporation of SPEC
2C, the Fifth Edition of API's Recommended Practice Specification for
Offshore Cranes. On February 14,
2003, MMS published a final rule (68 FR 7421) incorporating API
Specification 2C, Fifth Edition, into MMS regulations.
API Spec 2C,
Specification for Offshore Cranes Fifth Edition, April 1, 1995, will
establish detailed requirements for the design and construction of new
pedestal mounted cranes for fixed OCS platforms. It will provide a uniform
method of establishing rated loads for cranes. This rule also requires
lessees to equip all existing cranes installed on fixed OCS platforms with
anti-two block safety devices.
Require
third party inspections/certifications. Although this recommendation has been seriously debated in past
conferences and workshops the Bureau is not on board with this recommendation.
Review
the need for regulating booms and other material-handling equipment.
The Bureau
will add a new requirement to the regulations that requires lessees to
operate and maintain all other material-handling equipment in a manner that
ensures safe
operations and prevents pollution. The Bureau expects that this requirement
(contained in the Final Rule for Subpart A) will be published in the
Federal Register
in November or December 1999. This new requirement will be found at 30 CFR
Part 250.108(f).
Additionally, the Bureau is currently drafting a rule to address this requirement
in more detail―
this rule will incorporate standards e.g., API, ASME, ABS, etc. That
addresses our material handling concerns, whatever is not addressed in these
standards will be written out in the rulemaking process.
Improve
accident investigations and reports.
The Bureau is taking the following actions to improve its accident
investigation program:
 |
Developing new accident reporting requirements in
conjunction with USCG to provide clearer accident reporting thresholds; |
 |
Developing guidelines with USCG for coordinating
accident investigation responsibilities and data sharing;
|
 |
Improving internal accident forms and database
management procedures; |
 |
Established the Office of Safety Management in the
Gulf of Mexico
Region; |
 |
Developing a better method for tracking and ensuring
follow up of accident investigation recommendations; and |
 |
Developing a strategy for publicizing more accident data
and analyses. |
On July 8, 2003, the
Bureau
published a proposed rule for incident reporting in the Federal Register. The comment period closed in early December, and
the Bureau is currently working
with the USCG to review the comments and finalize an incident reporting
regulation. Through this effort, the Bureau will work with the USCG to better
coordinate incident investigations and data sharing. To help the Bureau improve
incident investigations and analysis of incident data, the Bureau is completing the
development of a crane and materials handling database and a questionnaire
for inspectors and engineers to use during the investigation of crane and
material handling incidents.
Industry/Bureau
workshop on crane safety.
The Bureau has conducted and participated in several workshops since 1998 the
most recent industry/Bureau sponsored activity was the Offshore Crane
Operations and Safety Conference 2003, held in Lafayette on June 25, 2003.

Crane Accidents from October 1998 through
October 1999
The Bureau has identified 13
offshore crane incidents (plus 2 serious incidents involving the use of
booms or other materials-handling equipment) for this time period. Three
incidents resulted in a fatality in each incident. The first fatal incident
occurred on October 19, 1999, when a diverter being lifted by air hoists
struck the controls of another set of air hoists. The Texas
deck, which was controlled by the second set of air hoists, shifted and
pinned a welder against conductor pipe. The second fatality occurred on
October 27, 1998, when a crane operator was killed after the crane pedestal
failed. The crane was handling an anchor. The last fatality involved the
drowning of a diver on August 29, 1999. The diver was being lowered into the
water when a sheave on a hoisting boom failed. The sheave failure caused the
diver to come in contact with the platform and damaged the diver’s aqua
suit.
Crane incidents
continued to injure people working in or around offshore cranes. Seven
injuries occurred during the 13 incidents. Most of the injuries were broken
bones. The injured included 2 riggers, 1 crane operator, 2 riders in a
personnel-basket, and 2 workers not associated with the crane activities.
Damages from these
incidents ranged from no damage to major. The most significant damage
occurred on December 3, 1998, when the cable on a derrick barge failed during the
installation of a large production module. The module damaged the barge and
then sank to the seafloor where it will not be recovered. Five incidents
caused varying degrees of damages to cranes or crane booms. And loads were
also damaged or lost when they were dropped on 4 occasions.
Human error and
equipment failure continued to play a role in most of the accidents. These
categories were listed as the cause of 9 of the 13 crane incidents. They
were also listed as the cause of the 2 materials-handling equipment
incidents.
