Limited work approved on Mariner East

Despite construction suspension, Energy Transfer will still able to perform inspection and maintenance activities on the Mariner East pipelines.

Energy Transfer was forced to halt construction of the natural gas liquids pipeline system in Pennsylvania this week due to enhanced safety measures implemented in response to the COVID-19 pandemic.

With the company’s pipeline systems and facilities deemed life-sustaining activities, Energy Transfer will continue to operate its in-service assets, while work sites associated with Mariner East will be monitored and maintained.

Energy Transfer said it was in the process of securing, stabilising and moving equipment at these sites and would continue to work with regulators and local stakeholders to ensure worksites were maintained in accordance with the law during the shutdown.

When complete, the Mariner East pipelines will run 560 km and transfer natural gas liquids from the Marcellus and Utica shale fields to markets in Pennsylvania.

Mariner East 1 was completed in 2015, while some areas of the Mariner East 2 are still under construction.

Combined, Mariner East 1 and 2 will carry 345,000 bbl of natural gas liquids per day.

Energy Transfer is also constructing the Mariner East 2X to run parallel to the Mariner East 2 pipeline, which will carry 250,000 bbl of natural gas liquids per day.

It is targeted for completion some time in 2020.
