Multi-beam surveying
Multi-beam surveys are used to gather detailed information about the features on the seabed by measuring multiple depths from a single transducer array at high resolution. The result is a highly accurate 3D picture of the sea floor.
It has many added advantages over the single beam surveys. It provides higher resolution data as per the International Hydrographic Organization (IHO) standards, is more time efficient, has less errors and captures additional data such as the seabed texture and type.
The Teledyne Odom Hydrographic MB2 used by Water Solutions has its own unique features such as real time roll stabilisation, which minimises the effect on the accuracy of the data caused by the waves hitting the vessel. There is an additional Applanix POSMV positioning system to maintain high level positioning accuracy under the most demanding conditions.
Our Multibeam can measure to a depth of 200m with a swath of up to 140°
APPLICATION OF MULTIBEAM
Some of the applications of Multibeam surveys are:
Surveying of water courses such as harbours and ports.
Near-shore coastal environments.
Pre-design surveys used for determining pipeline or cable routes.
Offshore projects such as the inspection of pipelines.
Coastal protection survey for breakwaters.
Pre and post dredge survey for reclamation and dredging projects.
General hydrography of the sea floor.
Large scale mapping of ocean.
Exploration of wrecks and mapping of dive sites.
TELEDYNE ODOM MB2
The ODOM MB2 Multibeam Echosounder is developed for fast mobilisation on smaller vessels and is optimised for shallow water surveying. When it comes to collecting, this high resolution system is easy to deploy and mobilise to all parts of Maldives.
SURVEY VESSEL WS MORESBY
WS Moresby is a custom designed survey vessel that has ample deck and cabin space for survey operations. It comes with sufficient storage space and mounting points installed for a full MBES system. The draft of this vessel is only 0.4 m, which makes her perfect for coastal surveys. WS Moresby can operate in conditions of up to 2m of waves and can survey up to 200 m depth.
The vessel is equipped with twin Yamaha outboard engines and is capable of traveling to anywhere in Maldives. The vessel can be mobilised within 2 to 3 hours to any site.
