New Multibeam System

Atlas Fansweep Coastal, the first of a new series of advanced Atlas Fansweep 30 multi-beam echosounders designed to exceed IHO standards over depths in excess of 600m, has been introduced by Atlas Hydrographic. Developed for both hydrographic survey and oceanographic research applications covering waterways and coastal regions extending to continental shelf boundaries, the system features enhanced levels of data quality to reduce general post-processing requirements. Operating between 100 and 200kHz, with broadband frequency coverage depending on water depth and conditions, it additionally features simultaneous multi-ping technology for concurrent transmission of multiple steered pings in a water column. This ensures significant... (read more)

Multibeam Data Processing

Using CUBE Surfaces for Nautical Cartography and Dredged Measurements
This article is about the evolution of acoustic sounders imposed on Hydrographic Service’s new methodologies for the interpretation, handling and application of hydrographic information. Considering spatial resolution and high-density data acquired by multibeam echosounders (MBES), algorithms such as Combined Uncertainty Bathymetry Estimator (CUBE) are used in the processing workflow to generate depths and uncertainty estimates. Can bathymetric surfaces be considered the final survey product in exchange of the traditional shoals selection? IHPT conducted hydrographic surveys in order to evaluate CUBE processing for nautical cartography and for dredged volume calculation. Shoals validated by hydrographers were compared with CUBE estimated depths and... (read more)

Spanish Navy Extends Multibeam Capabilities

Kongsberg Maritime has entered into a contract with the Spanish Hydrographic Institute of the Navy (IHM) to deliver and install the EM 302 1ºx2º on its survey launch, H/V Malaspina. The system will be installed during the mid life upgrade program starting in 2007 and will form a key part of an integrated survey package consisting of the EM 302, EA 600 12 kHz and Seapath 200. Today, IHM operates two 12.5 metres hydrographic launches, Malaspina and Tofiño. Both utilise Kongsberg Maritime hydrographic equipment. The launches have surveyed the majority of Spanish harbours. The level of detail facilitates to define... (read more)

Klaipeda Seaport Takes ELAC Multibeam

ELAC Nautik has recently delivered and successfully integrated a complete hydrographic solution, S/V VARUNA, to Klaipeda State Seaport Authority (KSSA). KSSA now operates two shallow water systems SEA BEAM 1185. The system is designed for both high-accuracy harbour and near shore surveys and offers the newest Coastal Oceanographics software solution with high precision Aquarius DGPS/ RTK positioning system and MAHRS motion sensor/ gyrocompass. A Valeport CTD guarantees reliable water profiles. (read more)

Multibeam System for PD Teesport

Saderet has supplied a complete MB2 multibeam system to PD Teesport for high accuracy port surveying. The system was installed on one of Teesport’s hydrographic survey vessels, the Tees Sentinel. Included in the package was a Hemisphere AtlasLink L-Band RTK positioning system, USM sonar mount, Applanix Wavemaster INS, and Teledyne Reson SVP70 for sound velocity measurement at the sonar head. A Valeport SWIFT SVP was also provided for sound velocity measurement over the whole water column. This contract follows on from another recent MB2 package project provided by Saderet for a Suffolk, UK based inshore hydrographic survey company. Saderet is... (read more)

High-resolution Multibeam Surveys Completed

Coastline Surveys Ltd (UK) has completed three high-resolution multibeam hydrographic surveys in the Southern North Sea, using the latest-generation R2SONIC 2024 combined with an iXBlue Octans MKIII Gyro / MRU and C-NAV 3050 RTK GPS positioning. The survey vessel MV FlatHolm managed to complete the three surveys in quick succession during short weather windows, with minimal downtime due to weather for clients in offshore dredging, marine renewables and energy decommissioning sectors. Vessel mobilisation was supervised by Andy Johnson, CSL’s head of Hydrographic Services, who brought his extensive knowledge and experience of the R2SONIC 2024 system to bear on the projects....

Two Multibeam Echosounders for China

The Shanghai Da Hua Surveying and Mapping Company have ordered two more ATLAS FANSWEEP 20 shallow water mapping systems for their hydrographic surveying tasks. Most of the work is carried out for their mother company, the Shanghai Dredging Company. In addition to a former system already in use since more than ten years, the customer decided to increase the capacity of his survey fleet with two 200kHz versions ATLAS FANSWEEP 20 multibeam echosounders.The identical configuration for both systems consists of ATLAS FANSWEEP 20-200, ATLAS HYDROMAP CONTROL software for sensor steering and control, HYPACK & HYSWEEP data acquisition software, IXSEA OCTANS...
