Multibeam Survey

The key success factor in a project is from beginning to have accurate documents about whether the project is in the ground or near the water. For projects as adjacent until the water it is often Det finns Floating Units involved AS is costly. It can be small rafts or larger barges, Construction ship or jack-ups. To eliminate and minimize shutdown as diet Bero into wrong actions, we understand that it is imperative that produced documentation are correct. We work according to interrogation 3 U principle to ensure and exceed customer expectations.

The right equipment, the right training and the right execution.

Harbour mapping
Mapping of waterways
Seabed mapping

In order for your projekti is to be successful, we offer EN variety of approaches with elaborate methods to set producing material for your project. Applicability In Methods can-be:

Multibeam sonar-ing
High Definition “multi-beam sonar” as integral Simply locate small objects without available maps Bottom, construction works in harbors and offshore to your needs. All measurements with multibeam sonar UTFORS comprehensive associated sensors and is in accordance with local requirements from the Transport and Sj√∂V, FSIS-44 (IHO S-44).

Mechanical ramming
As a result of the demand in hydrographic surveys Mechanical ramming we have developed successful ramningsmetod. We offer turnkey solution for hydrographic surveys with both framing and multibeam echo sounding. With our mobile unit-framing can be offered to customers throughout Sweden. All hydrographic surveys with frame and multibeam sonar UTFORS shown According to local requirements.

Sub-bottom profiles
This method is used to investigate the strata determined by sea or ocean floor. This can-be vital to know whether the bottom sediment’s properties are, for example placement of the lake bed lines. Sub-bottomprofilern available Can be used to quantify dredging needs and identify where boxes mountains.

Sub-bottom profiles the equipment has a variety of applications where we customize our methods and guides you in your projects.

Side scan sonar
I often used combined with sub-bottom profiles to interpret ytgeologiska conditions. With High resolution geophysical equipment can-Very Small objects located Which can-Getting to benefit in different contexts. At the project as have the need to locate objects in botten then this equipment is optimal.

All data collected as raw data

No finishing is done in real time during the actual collection of data. Data is stored continuously in real time, and ultimately saved in the file after each run on the line.

Raw data after processed with software from Eiva (NaviEdit), the data is compensated for the measured movements, and developed starting values for the various sensors. Starting values obtained from the execution of the known point as above.

During follow-cleared data from the obvious erroneous registrations. Criteria for false registrations as well as other criteria in respect of quality into account during this process.

The end result of post-treatment will be a number of XYZ files, which contain measured and according to the above items checked from the measurements made.

These XYZ files are input for the establishment of a digital terrain model of the measured areas.

The terrain model created using the software NaviChart from Eiva A / S. Based on the established model, created drawings for the final accounts.
