S/V «Trias» is capable to carry out geotechnical surveys of soils in the boreholes to the depth of 150 m at the water depth up to 300 meters.
Survey vessel «Trias» is a special-purpose vessel of KMIce class [1] is designed for drilling of engineering-geological boreholes and performance of geotechnical surveys. The vessel is capable to carry out geotechnical surveys of soils in the boreholes to the depth of 150 m at the water depth up to 300 meters using steel drill pipes and to the depth of 500 m using light-weight drill pipes, to study soil cross-sections and their characteristics using the shipboard equipment (hydraulic, gravity and hydrostatic corers, seabed CPT) and using the stern portal frame with the capacity of 10 t and the overboard handling radius of 3 m.
