The RV Ridley Thomas approaching Dili Harbour, Timor Leste
EGS (Asia) Ltd. has been awarded a contract by Toke Oil&Gas SA in partnership with the State Secretariat for Natural Resources of the Government of Timor-Leste to carry out a bathymetric survey covering the entire East Timorese southern offshore area. The total survey area covers 43,000sqkm, of which 50% are in water depths deeper than 1500m (maximum water depths: 3,500m). The deep water survey (water depths deeper than 1500m) was carried out by the RV Ridley Thomas using her Simrad EM12 full ocean depth swathe bathymetry system in June/July 2008, acquiring in excess of 5,500 line km of swathe bathymetry data within a period of 23 days. The shallow water survey is currently ongoing and is carried out by the MV Northern Light using a 50kHz Elac MkII swathe bathymetry system.

EAST JAVA GAS PIPELINE INSPECTION, North Bali Sea, Indonesia (2006)
Launch of the Triton ROV c/w pipeline skid and dual head Reson Seabat 8125 swathe bathymetry transducer
Pertamina contracted PT Cwamas Citra Prakarsa (EGS’ Indonesian Partner) to conduct ROV based pipeline inspection work along 285km of the East Java Gas Pipeline from Pagerungan island to Madura Straits, Indonesia, using video cameras and dual head swathe bathymetry systems mounted on an ROV. The ROV work was subcontracted to Geo Subsea who also provided the MV Geo Sea for the work. EGS provided positioning, MBE processing and charting services.
Phase 1 of the survey work included analogue sub-bottom profiling and geotechnical (CPT, vibro coring) in the immediate vicinity of the “live” pipeline. This was carried out using the Indoensian Research vessel KR Baruna Jaya VIII. A total of 20 vibro cores and 40 MCPTs were collected.
Phase 3 of the project involves met ocean data recording (currents) over 65 days at eight locations along the pipeline. - JDA
