MMT Installs Kongsberg EM2040 Echo Sounder on Its Multi-Purpose Vessel

March 25, 2014

MMT Group has acquired a Kongsberg EM2040D.

A 0.4 x 0.7 degree dual head multibeam system has recently been installed on MMT’s long term charted multipurpose support vessel (MPSV) Stril Explorer.

This is a highly developed multibeam echo sounder that combines all of the advanced features of deepwater echo sounders to the shallower water or ROV/AUV environment. Such features include:

Dual swath per ping to maintain a high survey speed at maintained resolution.
FM chirp to achieve a much longer range capability
Complete roll, pitch and yaw stabilization
Near-field focusing both when transmitting and receiving

Typical applications for the EM 2040 Multibeam echo sounder

Mapping of harbours, inland waterways and shipping channels with critical keel clearance
Inspection of underwater infrastructure
Detection and mapping of debris and other underwater objects
Detailed surveys related to underwater construction work or dredging
Environmental seabed and habitat mapping
Mapping of biomass in the water column

By owning and operating an EM2040 dual head on Stril Explorer, MMT is further prepared to perform surveys that meet the IHO-S44 special order and fulfills the requirement for high resolution pipeline inspection. This investment has advanced MMT’s surveying operations and it supports MMT Group’s standing as a unique and highly advanced competitor in the marine surveying field.
