Abstract

A demand for laying an observation cable system on a planned route position precisely has become higher and higher. JOGMEC, JGI, OCC and KCS carried out a methane hydrate dissociation monitoring survey under the seabed by using DSS (Deep-sea Seismic System) last year. The laying position of the seismometer located in the central of the DSS was required to lay at a distance of 40 m from the methane hydrate production well at the water depth of about 1,000 m. KCS has successfully achieved the DSS laying within the targeted deviation. The paper describes the details of the developed simulation system and successful laying / burial operation.
