LNG Peak Shaving Facility, New Jersey

OVERVIEW
This LNG peak-shaving facility will consist of a large LNG tank, vaporizer system, truck loading and unloading rack, and other associated facilities. Located on a brownfield site in an industrial setting, the facility site has a history of waste management and is challenged by nearby wetlands and streams. Langan’s civil, environmental and traffic engineering groups are working together to support property assessment, optimal facility layout and facility permitting.

LNG Peak Shaving Facility, Pennsylvania

OVERVIEW
This LNG peak shaving facility has a 2-million-gallon LNG tank, vaporizer system, truck loading and unloading rack and other associated facilities on an 85-acre property. The facility is located in a greenway area with a variety of environmental constraints including wetlands, floodplains, and steep slopes. Langan’s multidisciplinary service groups worked together to support various tasks including property assessment, facility planning, detailed facility layout, and land development permitting.

LNG Peak Shaving Facility, New England

OVERVIEW
This LNG peak-shaving facility will consist of a large LNG tank, vaporizer system, truck loading and unloading rack and other associated facilities. The facility is located in a rural, ridge top area. Langan’s civil and environmental teams prepared facility layout and land development concepts to site the facility in the optimal location based on development constraints, including steep sloping terrain, the presence of streams and wetlands, and the need to maintain access to other areas of the property. Langan’s environmental team also completed a preliminary impact study and environmental assessment.

Confidential Refinery Modernization Project

OVERVIEW
The multi-billion dollar modernization effort involves fast-tracked geotechnical and seismic engineering studies for the modernization of this large refinery located on the Pacific coast. The ground motions and tsunami microzonation studies performed by Langan and our subconsultant were consistent with the definitions of the levels of earthquake “shaking” in the Peruvian code. The team performed both probabilistic seismic hazard analysis (PSHA) and deterministic analysis to develop the spectral acceleration estimates and tsunami wave runups required as part of the microzonation study. Langan performed an extensive two phased geotechnical study consisting of more than 100 test borings to 30-meter deep and 100 25-meter deep cone penetrometer tests. An array of geophysical testing was also performed to complement the borings and evaluate the subsurface conditions.

Transfer Facility – New Stormwater Outfall

OVERVIEW
Our client is transforming a former oil refinery into a liquid product transfer facility, which is undergoing renovation and reconfiguration and requires a new direct discharge line to be installed. Langan is assisting the client with the field investigation for the installation of a new stormwater outfall line from the waste water treatment facility. Our team performed a thorough underground utility survey to clear the way and adjust the alignment of the new 1,900-FT-long outfall pipe. We utilized a specialty utility locating and mark-out contractor to perform this task under our direct full-time supervision, and performed a focused topographic and utility survey of the outfall alignment area to confirm and supplement the available survey information. Langan also assisted the outfall designer in selecting a suitable alignment for the outfall pipe, performed a geotechnical field investigation for the outfall alignment and the discharge headwall, and provided deep foundation recommendations for their support.
