PT Mahakarya Geo Survey is an Indonesian company specializing in Marine
Geophysical and Hydrographic Survey. They recently purchased an EM 3002 high resolution
shallow water multibeam system along with an MRU-H motion sensor for accurate motion

The system has been utilized on a number of interesting projects around Indonesia
including hazardous site surveys, pipeline inspection surveys, engineering surveys
and hydrographic charting applications. During the middle of this year the EM 3002 (now replaced by the more modern EM 2040)
was successfully used to detect a previously uncharted shipwreck lying off the North
West Coast of Java Island in approximately 50m water depth. The wreck is very large
(over 100m in length) and seen from the EM 3002 imagery to be lying on its side
and still largely intact. It also proved useful as a feature for running the patch
test routine for calibrating the EM 3002 multibeam system.
More recently Mahakarya Geo Survey acquired an EA 400SP high accuracy single
beam echo sounder to add to their equipment pool. Director of the Mahakarya Geo
Survey Mr. Henky Suharto explained his preference for Kongsberg Equipment: "KONGSBERG
is a well established manufacturer that delivered the best quality in both accuracy
and resolution especially with its Multibeam systems. We find KONGSBERG systems
to be user friendly and we like the EM 3002's compatibility with other software,
such as QINSy Ver 8.0. Last but not least, Kongsberg's excellence of technical support
bought us the confidence that we were making the correct choice."
