Improved pipeline safety needed at all levels, NARUC committee told

Oil and gas pipelines and the government agencies that regulate them are making progress in improving safety and responses by emphasizing greater involvement at all levels, the National Association of Regulatory Utility Commissioner’s Natural Gas Committee learned on Feb. 10.

“All sectors of the industry have embraced the goal of zero accidents through continuous improvement,” Jeffrey Wiese, associate administrator for pipeline safety at the US Pipeline and Hazardous Materials Administration, said at the session during NARUC’s 2014 Winter Committee Meetings.

“Regulators don’t operate pipelines,” Wiese said, adding, “Our job is to influence those who do. Some of this involves enforcing regulations, but a lot of it involves working together.” Within the companies, he said PHMSA has found that “management has to walk the walk, and not just talk the talk,” adding, “But there also has to be commitment at lower levels.”

John Vorderbrueggen, chief of the pipeline and hazardous materials division at the National Transportation Safety Board, said NTSB went to the American Petroleum Institute after a July 2010 leak at an Enbridge Inc. pipeline in Michigan spilled crude oil into the Kalamazoo River to develop nonmandatory safety and response guidelines for operators to use.

That accident, which became the costliest onshore environmental event in US history ($2 billion and counting), revealed serious operating lapses in employees’ responses as well as problems in the pipeline itself, he indicated.

NTSB encourages its investigators to examine the entire organization when examining an accident, he told the committee. “It’s important to capture all the data when a pipeline is built so it can be studied later, but that’s not always possible since much of the pipelines in the ground were installed before this became the customary procedure,” Vorderbrueggen said.

Hidden infrastructure

“Also, with pipelines, most of the infrastructure is out of sight, unlike refineries or chemical plants,” he continued. Employee lapses during operations can lead to accidents, sometimes accumulating in seemingly innocuous ways that lead to trouble, Vorderbrueggen said.

Nick Stavropoulos, executive vice-president for gas operations at PG&E Corp., said that when he joined the California utility holding company after a September 2010 explosion and fire at one of its lines in San Bruno, Calif., killed 8 people, injured dozens more, and destroyed several homes, he found a culture of “positive discipline” that needed to be replaced.

The nonpunitive self-reporting that PG&E now encourages employees to use has increased the number of identified potential problems 850% in the time since, he noted. “It’s not that we’ve grown worse,” Stavropoulos explained. “It’s simply being reported more so we can do something about it.”

The pipeline asset management program PG&E adopted has transformed the company, which has satisfied nine of NTSB’s 12 recommendations following the San Bruno accident and expects to satisfy two more in another few months, according to Stavropoulos.

“We encourage our leaders to get out and talk to the people in the field,” he said. “It makes a huge difference to have someone from management visit a plant yard or pipeline to learn what people are doing, and thank them for it.”

Prevention, Detection and Mitigation of pipeline leaks in the modern world

When Thu, Apr 30, 2015

Preventing, detecting and mitigating leaks or commodity releases from pipelines are a top priority for all pipeline companies. This presentation will look at various aspects related to preventing, detecting and mitigating pipeline commodity releases from a generic and conceptual point of view, while at the same time look at the variety of offerings available from Schneider Electric to meet some of the requirements associated with pipeline integrity management.

Global LNG: Adjusting to New Realities

Fri, Mar 20, 2015

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.

The Future of US Refining

Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
