We have completed the mid-life refit of the hydrographic survey equipment onboard
the (Oceanographic Research Vessel) 'B.I.O Hesperides'. The vessel, originally commissioned
in 1991 and based in the Antarctic seas for 6 months a year, was one of our first
large survey equipment installations. Likewise, this is the first full mid-life
refit of survey equipment carried out by the company.
The survey package supplied and installed was based on the EM120 1°x2° multibeam
echosounder. The EM120 is a tried and tested multibeam sounder for deep water mapping
with the 12 kHz operating frequency being the optimum choice in order to achieve
efficient mapping of larger ocean areas. However, the system can be applied to mapping
of shallower water areas, and can cover a swath of 6 times the water depth. We also
supplied an EA600 hydrographic echosounder and a PS18 parametric sub-bottom profiler
as part of the hydroacoustic survey package.
We bolstered the survey package by supplying our industry standard scientific
echosounder, the EK60. In addition we supplied a suite of new navigation equipment
for the bridge including an AP50 autopilot, EN250 navigation echosounder and Skipper
DL857 doppler log for speed along track measurements.
We completed the refit with the new Seapath 200 heading, attitude and positioning
sensors. Seapath 200 is an integrated navigation sensor ideal for a range of applications
including hydrographic survey and oceanographic research, where accurate compensation
of multibeam echosounders, hydroacoustic positioning systems and ADCPs or vessel
motion monitoring is required. The Seapath can also be used for continuous calibration
of gyrocompasses onboard a vessel.
“The project was based on the replacement of the vessel’s existing survey equipment
but several other KONGSBERG product groups were also involved,” says Vicente Carrasco,
Sales Manager, Simrad Spain. “The added value of this close co-operation for KONGSBERG
Customers is that we can offer the Full Picture. Instead of using several suppliers
for different systems, the ‘B.I.O Hesperides’, benefited by getting its survey,
navigation and position reference systems from just one source.”
