大规模气体爆炸的八天后，劳伦斯，安多佛和马萨诸塞州北安多夫斯官员宣布了雄心勃勃的60天计划，以取代48英里的天然气管道和相关基础设施。官员们说，可以在接下来的两周内将2,000米重新服务，并计划在11月19日之前完成整个重建。

州长查理·贝克（Charlie Baker）在9月21日的新闻发布会上说：“每个人的首要任务是安全。”“团队已经制定了一项计划，以满足所有级别的安全性，并旨在快速有效地完成每个步骤。”

这9月13日爆炸were caused by extra pressure coursing through a Columbia Gas natural gas pipeline, according to the National Transportation Safety Board (NTSB), which says its full investigation into the cause of the incident could take up to two years. The explosion set 80 buildings on fire, killed one person, injured several others and displaced scores of people who are now left without natural gas heading into the winter season.

“经典工程意外事件”

Baker also announced Sept. 21 that former Navy Seabee Joseph Albanese will oversee the effort to restore full gas service to 8,527 customers. The retired Navy captain who commanded a division of the United States Naval Construction Battalions is a professional engineer who founded Commodore Builders. He currently serves as the Boston-based firm’s chief executive.

“This is a classic engineering contingency operation, one I’m trying to do with my military experience behind me and my construction experience in the local markets,” Albanese said during the Sept. 21 briefing. “I’ve been tasked to build a team to provide command, control and communications to manage this effort, and safety will be paramount.”

Christina Sames, the American Gas Association’s vice president of operations and engineering called Albanese a “respected outside party who has experience in a variety of areas.”

Albanese retired from service as a captain in the U.S. Navy Civil Engineer Corps in 2009 after extensive service in the Middle East. He says dozens of “highly qualified firms and thousands of workers” have already been assembled and are being supported by the Massachusetts National Guard. “This has been and will continue to be an overwhelming effort,” he said.

这项工作比初始时间表更合理。上周，哥伦比亚天然气发言人告诉波士顿环球报，该公司计划在9月底之前完成该项目，这是几位安全专家警告说的时间表太快了。总部位于华盛顿的管道安全公司Accufacts Inc.总裁Richard Kuprewicz告诉ENR，新的时间表更加“合理和可行”。新利18备用

Sames said New Jersey Natural Gas completed similarly sized projects after pipelines were damaged by Superstorm Sandy.

马萨诸塞州的重建涉及用塑料管，最先进的基础设施和安全功能（例如，如果服务线损坏或破坏，它们会自动关闭气流，则用塑料管，最先进的基础设施和安全功能代替现有的铸铁和裸露钢配电系统。拥有哥伦比亚天然气的印第安纳州公司Nisource Inc.首席执行官乔·哈莫克（Joe Hamrock）在一份声明中说：“只有在对新设施进行了全面检查，测试和经过证明的安全性之后才能恢复服务。”

截至9月21日，二十名船员在地面上，阿尔巴尼斯表示，到9月24日，到10月8日，这个数字将增长到60岁。阿尔巴尼斯说，阿尔巴尼斯说他“自信”他的团队将“满足并超过对的期望社区。”但是他还指出，“我们不能低估我们面前的需求。”

联邦管道和危险材料安全管理局的顾问Kuprewicz表示，机组人员的规模并不像防止新爆炸在如此迅速工作的同时隔离活跃的气压那样重要。他说：“随着您激活越来越多的旧系统，隔离可能会滚动。”“重要的是，他们必须制定协议和程序，以确保活跃的气体不会进入他们正在处理的系统。”

He added the project team has an advantage because the work had already been planned, though intended for completion over years instead of months. Kuprewicz also said the fact the gas is already shut off will help the crews expedite work.

环境al Partners Group, a Quincy, Mass.-based engineering firm, was hired by Lawrence, North Andover and Andover to serve as the construction manager for the three municipalities.

Crews to Deliver Heaters, Cooktops

Crews have already started delivering and installing 24,000 electrical space heaters and 7,000 self-contained cooktops to homes unable to use gas-powered stoves and furnaces. Teams that include electricians and plumbers will inspect homes to ensure the temporary appliances can be installed safely. If homes that are unable to use the temporary units can’t be rewired, the residents could be relocated, Baker said.

Sames said she was glad to see that the team has “a great plan in place” to inspect internal home gas lines because few companies have experience with internal lines —those lines are typically the customers’ responsibly.

她说：“替换管道本身以及向房屋和企业提供的服务，我们知道他们可以处理这一点，因为他们可以使用的资源。”“我们正在等待听到的房屋内。”

贝克无法估计马萨诸塞州的重建和救济工作的成本，但表示哥伦比亚将为此付出代价。他确实说：“由于上周事件的不可思议的环境和复杂性，康复之路将需要时间。”
