SUPPLEMENTARY INFORMATION:
I. Background
The purpose of this advisory bulletin is to remind all owners and
operators of gas and hazardous liquid pipelines, particularly those
with facilities located in offshore and inland areas, about the serious
safety-related issues that can result from the passage of hurricanes.
That includes the potential for damage to offshore platforms and
pipelines and onshore pumping stations, compressor stations, and
terminals.
Operators of gas and hazardous liquid pipelines have a general
obligation to identify any conditions that can adversely affect the
operation of their pipelines and to take appropriate corrective
measures upon discovering such conditions. Specifically, Sec. 192.613
of the gas pipeline safety regulations states that ``[e]ach operator
shall have a procedure for continuing surveillance of its facilities to
determine and take appropriate action concerning * * * unusual
operating and maintenance conditions,'' and that ``[i]f a segment of
pipeline is determined to be in unsatisfactory condition but no
immediate hazard exists, the operator
[[Page 54532]]
shall initiate a program to recondition or phase out the segment
involved, or, if the segment cannot be reconditioned or phased out,
reduce the maximum allowable operating pressure in accordance with
Sec. 192.619(a) and (b).'' Section 195.401(b)(1) of the hazardous
liquid pipeline safety regulations states that ``[w]henever an operator
discovers any condition that could adversely affect the safe operation
of its pipeline system, it must correct the condition within a
reasonable time. However, if the condition is of such a nature that it
presents an immediate hazard to persons or property, the operator may
not operate the affected part of the system until it has corrected the
unsafe condition.'' Section 195.401(b)(2) further states that ``[w]hen
an operator discovers a condition on a pipeline covered under [the
integrity management requirements in] Sec. 195.452, the operator must
correct the condition as prescribed in Sec. 195.452(h).''
Operators of shallow-water gas and hazardous liquid pipelines in
the Gulf of Mexico and its inlets have a specific obligation to
``prepare and follow a procedure to identify [their] pipelines * * *
that are at risk of being an exposed underwater pipeline or a hazard to
navigation * * * [and to] conduct appropriate underwater inspections *
* * [of those pipelines] based on the identified risk[;]'' and upon
discovering that ``its pipeline is an exposed underwater pipeline or
poses a hazard to navigation,'' to promptly report the location of that
pipeline to the National Response Center, to mark its location, and to
ensure its reburial within a specified time. 49 CFR 192.612, 195.413.
Hurricanes can adversely affect the operation of a pipeline and
require corrective action under Sec. Sec. 192.613 and 195.401.
Hurricanes also increase the risk of underwater pipelines in the Gulf
of Mexico and its inlets becoming exposed or constituting a hazard to
navigation under Sec. Sec. 192.612 and 195.413. The concentration of
U.S. oil and gas production, processing, and transportation facilities
in the Gulf of Mexico and onshore Gulf Coast means that a significant
percentage of domestic oil and gas production and processing is prone
to disruption by hurricanes.
In 2005, Hurricanes Katrina and Rita caused significant damage to
the oil and gas production structures. The onshore damage caused a
significant impact in the ability of the oil and gas industry to
respond due to the lack of resources, personnel, and infrastructure, as
well as significant damage to onshore processing facilities and power
supplies. There were significant competing resource needs with the
impacts caused by the devastation of New Orleans and western Louisiana/
eastern Texas shore communities that normally provide the services and
supplies for the industry.
II. Advisory Bulletin (ADB-11-05)
To: Owners and operators of gas and hazardous liquid pipeline
systems.
Subject: Potential for damage to pipeline facilities caused by
hurricanes.
Advisory: All owners and operators of gas and hazardous liquid
pipelines are reminded that pipeline safety problems can occur by the
passage of hurricanes. Pipeline operators are urged to take the
following actions to ensure pipeline safety:
1. Identify persons who normally engage in shallow-water commercial
fishing, shrimping, and other marine vessel operations and caution them
that underwater offshore pipelines may be exposed or constitute a
hazard to navigation. Marine vessels operating in water depths
comparable to a vessel's draft or when operating bottom dragging
equipment can be damaged and their crews endangered by an encounter
with an underwater pipeline.
2. Identify and caution marine vessel operators in offshore
shipping lanes and other offshore areas that deploying fishing nets or
anchors and conducting dredging operations may damage underwater
pipelines, their vessels, and endanger their crews.
3. If operators should need to bring offshore and inland
transmission facilities back online, check for structural damage to
piping, valves, emergency shutdown systems, risers and supporting
systems. Aerial inspections of pipeline routes should be conducted to
check for leaks in the transmission systems. In areas where floating
and jack-up rigs have moved and their path could have been over the
pipelines, review possible routes and check for sub-sea pipeline damage
where required.
4. Operators should take action to minimize and mitigate damages
caused by flooding to gas distribution systems including the prevention
of overpressure of low pressure and high pressure distribution systems.
PHMSA would appreciate receiving information about any damage to
pipeline facilities caused by hurricanes. The Federal pipeline safety
regulations require that operators report certain incidents and
accidents to PHMSA by specific methods. Damage not reported by these
methods may be reported to John Hess, Director for Emergency Support
and Security, 202-366-4595 or by e-mail at [email protected].
