Summer Field Work in Cook Inlet

Summer field work continues in the Cook Inlet this season, including mapping and soil sampling of the seabed floor. Marine geotechnical work started in early April on the west side of the Cook Inlet. Working in slack tide with six thrusters holding it in position, a 240-foot vessel lowered a three-ton piece of equipment that vibrates into the seabed and pulls core samples from approximately 15 feet below the seafloor. Crews then moved to the east side of the Cook Inlet, timing the work so it wouldn’t interfere with setnet fishing equipment and finished on April 20th. Seafloor mapping along the pipeline route across the inlet and at various potential job sites is scheduled to start in May.

Along with seabed samples, the team is analyzing onshore soil samples at the site of the proposed LNG Plant to ensure the ground can handle the weight of storage tanks and other major equipment. Each of the two LNG storage tanks would be large enough for a Boeing 747 to spin around inside the walls. The liquefaction plant, storage tanks, marine terminal, gas-fired power generation facility and everything else at the Nikiski site add to a significant investment, upwards of $20 billion dollars and more than 40 percent of the total Alaska LNG Project cost.

Project Map

The Alaska LNG Project is anchored by the Prudhoe Bay and Point Thomson fields. These fields are expected to deliver on average about 3.5 billion cubic feet of gas per day with about 75% from the Prudhoe Bay field and 25% from the Point Thomson field.
