What do Seismic Survey Vessels primarily do?

Seismic survey vessels primarily create maps of ocean floors by using sonar and seismic reflection techniques. These vessels are equipped with sophisticated technology that emits sound waves into the water and measures how those waves reflect off the seabed and subsurface geological formations. The resulting data helps geologists and oceanographers understand the geological structure beneath the ocean floor, which is crucial for locating oil and gas reserves, assessing marine habitats, and conducting geological research.

The other activities listed are related to the oil and gas industry but are not the primary function of seismic survey vessels. Transporting crude oil, setting up anchors for drilling, and supplying equipment to oil rigs are distinct operations typically carried out by different types of vessels specifically designed for those purposes. Seismic survey vessels focus on exploration and mapping rather than the logistical or extraction tasks associated with oil production.
