New system to meet the needs of port developers

FROM the open ocean to harbours, dams and creeks, privately-owned Australian company Mapping and Hydrographic Surveys (MHS) has extensive experience in all marine environments. Specialising in
remote areas, MHS has the technological knowledge and equipment to accurately identify the seabed for greenfield port investigations, engineering design, dredging surveys and under keel clearance surveys.
The company is aware of the growing trend for port development and marine infrastructure engineering to require broader and deeper geophysical investigations.
As such, MHS identifi ed that sub-bottom profiling geophysical techniques were falling short of requirements.
In response to this, together with a US consultant, the company developed a marine seismic tomography system to meet the needs of port development marine infrastructure engineers. Based on the
proven offshore oil industry 2D seismic system, MHS’s marine seismic tomography system is specifically designed to acquire high definition 2D reflection seismic and compressional P-wave velocity data within a target penetration depth of 50m. The company has been operating the system on a number of projects with considerable success.
Last year, MHS completed hydrographic and marine geophysical survey investigations for a new port study in Daru, Papua New Guinea (PNG), and chartered 500km of the Sepik River in PNG for Xstrata Copper. The company also recently completed submarine pipeline and power cable route surveys in PNG, the Gulf of Carpentaria and North Queensland’s Whitsundays. Major clients of MHS have included BHP Billiton, ExxonMobil, Oil Search, Xstrata, the Port of Brisbane and Port Hedland Port Authority.
