Sea-3 Providence looks to diversify LPG supply options

June 14, 2021 By    

Sea-3 Providence LLC is looking to incorporate propane rail supply into its LPG marine terminal and storage facility in Providence, Rhode Island, according to documents filed with the State of Rhode Island Energy Facility Siting Board.

The company says it plans to tie into existing rail within the marine industrial port complex as a way to provide ancillary operational enhancements to the LPG terminal. This would allow it to offload LPG by rail into six horizontal storage bullets and eventually to three truck racks on the property.

Currently, Sea-3 imports LPG to the facility where it is stored in a 19-million-gallon high-rise tank and loaded onto transports for use by propane marketers throughout the region.

Sea-3 Providence acquired the rights to the property and terminal in 2018, but the site had not been active since 2015. The company spent $10 million to modernize and restore the facility before bringing it back online.

This second phase of the operation would help Sea-3 Providence diversify its LPG supply options to meet a projected increase in demand over the coming decade, according to the filing. Sea-3 is awaiting the necessary approvals to move forward with the project.

Sea-3 is a wholly owned subsidiary of Blackline Midstream, an independent propane storage and wholesale company jointly owned by Blackline Partners, a private growth-oriented asset development company, and Sixth Street Partners, a global investment firm.
