The Gyre has executed numerous offshore Surface Geochemical “Seep Hunting” Exploration (SGE) and Heat Flow programs for the world’s leading petroleum producers. The Gyre is also capable of performing deepwater geotechnical coring including 20 meter Jumbo Piston cores (JPC), 40 meter CPT-Stinger acquisition. Other capabilities include environmental assessments, metocean, heat flow and environmental baseline studies (EBS).


This vessel is well suited for the following applications:
  • Seabed Geochemical “Seep-Hunting” (SGE)
