Monitoring System for Seafloor Deformation during Methane Hydrate Production Test

摘要

We have developed a monitoring system for seafloor deformationrnduring Methane Hydrate production test. Seafloor deformation isrnmonitored by measuring subsidence and inclination of the seafloor.rnSubsidence is measured with change of water pressure on the seafloor.rnAn inclinometer we selected is applied liquid electrolyte. According tornsimulation of seafloor deformation around the production hole, thernrange of subsidence will be from 0.1 m to 0.3 cm. This system hasrnbeen installed and monitored on the seafloor at East Nankai troughrnduring the production test of Methane Hydrate. We will continue thernmeasurement by September 2013.
