ASL Environmental Sciences has secured a contract for a three-year metocean-ice study program in Cook Inlet, Alaska for the proposed Alaska LNG Project terminal site. This turnkey metocean program includes program management, a PSO (protected species observer), vessel, HSE lead, data processing and analysis, and engineering inputs.
During the summer and fall of 2014, ASL deployed three Ice Profiler™/ADCP moorings close to Nikiski, Alaska on the Kenai Peninsula. Each mooring consisted of an Ice Profiler, ADCP, CT, and OBS Turbidity and was mounted in ASL’s own designed bottom frame or a taut-line mooring.
ASL Environmental Science’s latest project in the Caspian Sea is with KazEcoProject for CMOC/Shell in the NE Caspian Pearls Lease Block. ASL is collecting and analyzing data for input into engineering design. Remote sensing data from high resolution satellite images (SAR and optical) and ice charts will be analyzed along with ice draft data collected from two Ice Profilers™ and two ADCP moorings.
ASL deployed the bottom moorings in nine meters of water in December 2012 and recovered them April 2013. The remote sensing data was acquired via the Danish Meteorological Institute and the Norwegian Meteorological Institute.
Elvary Neftegaz has contracted ASL, through Metocean Engineers, to conduct three years of measurements at three sites for the Sakhalin Ice Measurement Program in the Northern Sakhalin 5 area. The first site deployment was in December 2005, then sites 2 and 3 were in March 2006 from a helicopter through thin sea ice and included two Ice Profilers with two ADCP Sentinal Workhorses. Each mooring contained one Ice Profiler and one ADCP with tandem ORE Cart releases. This is ASL's first project for Elvary Neftegaz.
ASL has completed a project that provided winter ice draft and ice velocity data in Cook Inlet, Alaska. These data are used to calibrate computer models of ice loads on multi-legged offshore oil platforms and these models are then used for studies of more severe ice environments.
Because of high tidal currents (up to 6 knots), ASL designed a low profile bottom frame to incorporate the Ice Profiler™, ADCP, and other instruments. The instruments were deployed at a depth of 29 meters in December 2003 and recovered in the summer of 2004. ASL has provided detailed analyses of the data collected for input to the computer models.
ASL was contracted to install a real-time ADCP system from an oil rig for a drilling program off Trinidad and Tobago, January - April, 2006. Current profile data was displayed in real-time on the rig and was also used for current predictions. Following completion of the program a report was prepared that included tidal analyses.
A year-long program of current profile, water level and temperature measurements are being carried out in the vicinity of exploratory offshore drilling in the area northeast of Equatorial Guinea.
Meteorological data (winds, air temperature, and humidity) are being measured concurrently from a weather station installed on the drilling platform. The year-long data sets will be analyzed to provide input to developing a production system for this area.
