LNG Interconnect Pipeline & Custody Transfer Metering

Natural gas interconnect pipeline and custody-transfer metering engineered and constructed to supply feed gas to a new LNG liquefaction and storage facility in Massachusetts.

Project Overview

ZAP supported an LNG developer in delivering the natural gas supply pipeline feeding a new liquefaction and storage facility in Massachusetts. Drawing feed gas from two existing interstate laterals, ZAP engineered and constructed roughly 3,300 linear feet of 10-inch mainline pipeline plus 2,100 feet of horizontal directional drilling, delivering pipeline-quality gas through a custody-transfer metering skid to the facility battery limit.

Pipeline Design & Custody-Transfer Metering

The pipeline consists of roughly 3,300 linear feet of 10-inch API 5L X-52 mainline, including 2,100 feet installed via horizontal directional drilling, carrying pipeline-quality gas at 535 psig from two existing interstate laterals to the facility battery limit. A custody-transfer metering skid measures gas volume at the point of transfer, with overpressure protection, cathodic protection, and an emergency shutdown valve installed at the code transition to protect the connecting facility.

Constrained-Corridor Construction & Site Coordination

ZAP’s construction scope included site clearing, access road and pad work, metering skid installation, and hydrostatic testing, coordinated with the connecting carrier’s crews throughout. The project navigated foreign-line and parallel water-line conflicts, rocky backfill conditions, and right-of-way restoration across wooded terrain. The scope demonstrates ZAP’s capability to engineer and construct natural gas interconnect pipelines and custody-transfer metering systems within a constrained corridor.
