ExxonMobil Alaska LNG LLC (AKLNG) has let a contract to Fugro for a geotechnical and geophysical (G&G) program.
The 2015 G&G program follows successful completion of a similar but smaller program carried out by Fugro in 2014.
The geotechnical scope of work includes drilling and sampling of borings for the onshore liquefaction facilities, marine terminal, and offshore pipelines. It also includes installation of monitoring wells, seismograph, and in situ measurement of soil properties.
The geological and earthquake engineering scope will include assessment of geohazards, source characterization, probabilistic seismic hazard, and site response analyses. Bathymetric, side scan sonar, reflection and refraction surveys and sub-bottom profiling also will be conducted to assist in developing an integrated site model, the group said.
“These studies will assist AKLNG and its contractors to proceed with the [front-end engineering and design] level design of the LNG terminal and associated offshore pipelines,” the companies said.
AKLNG is a consortium of ExxonMobil Corp., ConocoPhillips, BP PLC, TransCanada Corp., and the state of Alaska.
