MC streamers for Japan Coast Guards

The new vessel of the JCG will be equipped with SIG multi-channel streamers. The first streamer delivered to JCG is already on board the R/V Shoyo, operated by the Hydrographic & Oceanographic dept of JCG.

Two other survey vessel are under construction for deployment in 2019 and 2020, both with shallow water sounding equipment installed. Toyo Corporation, SIG's rep in Japan is promoting the MC streamers. The units of JCG have 24 channels, spaced at 2.5 m with a total active section of 96 m.

Santos, Italo Dantas, 2018, Investigaçao de vales soterrados na plataforma continental do RN utilizando sismica de alta resoluçao (sistema boomer).


"Seismic data were collected using a Boomer-type seismic source operating at 300J on the continental shelf of the Potiguar Basin near the municipality of Macau-RN, Brazil.

Two incised valleys were identified one whose maximum incision depth reaches 56 meters and the filling thickness is around 26.5 meters; and the second valley with maximum depth of incision reaching 76 meters, and filling thickness around 41 meters."

Exceptionnal sediments penetration for SIG boomer

The Shanghai Shenfeng Institute of Novel Geological Techniques Co. Ltd has taken possession of their new boomer SIG Pulse M2, and reported the first tests on the Yangtze River. Exceptionnal penetration at 90 ms TWT, even in the very shallow zone of 5 m water depth. The boomer was operated from a barge-type boat. The size of the system allows the operation from such small vessels. Training and tests at sea have been performed by the technical staff of Geo Marine Technology Ltd, Chinese agent for SIG France since 2007.

The Shenfeng Institute has a main business in applied geophysics : like seismic prospecting for oil and gas, minerals, active faults investigations, river bottoms subsidence, integrated geophysical survey for site or route of major construction projects on land and water, etc...
