Offshore 3D Laser Scanning

Versatility in many challenging applicatieons
Surveying is benefiting from continually evolving new technologies. One is 3D laser scanning, which is often used for measurements in complex industrial installations such as pipeline-rack crossings or entire petrochemical installations. Laser scanning is also increasingly being used in the field of prototyping and cultural heritage. In fact, it is safe to assume that this technology will be beneficial in any challenging environment, or for complex shapes. Laser scanners emit a narrow laser beam and then receive and process the signal returned by reflection from the object. Depending on the model selected, laser scanners can measure between 100 and 500,000... (read more)

Demo of Hydrographic Airborne Laser Scanning System

From 12 March to 16 March 2012, RIEGL carried out an extended bathymetric test with the new VQ-820-G hydrographic airborne laser scanning system in South Florida, USA. With assistance from the National Oceanic and Atmospheric Administration (NOAA), the new scanner was demonstrated to showcase and highlight its capabilities. The event also allowed the attendees the opportunity to meet RIEGL experts and to examine details of the VQ-820-G more closely. The bathymetric demonstration took place over the course of a week in various locations of South Florida, including Tampa, Fort Lauderdale and Key West. The basis of the operation was located...

Corrugated Wall Scan with Underwater Laser Scanning

Locating and investigating retaining wall deterioration in its early stages is critical for ensuring the protection of the coastline and for avoiding extensive repairs or costly replacement. ADUS DeepOcean recently deployed the 2G Robotics ULS 500 in profile mode to continuously scan and generate a high-resolution 3D model of a corrugated wall. The high resolution of the scans provided a detailed understanding of the wall’s condition and enabled signs of corrosion and wear to be easily detected. With underwater laser scanning, highly detailed 3D models can be generated in order to establish an accurate baseline and monitor the condition of... (read more)

MBES and Laser Scanning Training Course

In January 2014, UK-based Swathe Services will be working with Hydrocharting to run a multibeam echosounder and MDL laser scanning training course with QINSy software. This training course offers hands-on training with high-spec hydrographic survey equipment and will be conducted by experienced trainers with 3 days of boat-based training and 2 days of post processing. The 5-day course will be held in Southampton, UK, starting on Monday 27 January 2014 and finishing on Friday 31 January. Training will be given by James Williams of Swathe Services and Jesper Højdal of Hydrocharting using SONIC 2020 and SONIC 2024 multi-beam echosounders alongside... (read more)

Above-water Laser Scanning throughout NaviSuite Workflow

EIVA NaviSuite allows for integration with the Renishaw Dynascan range of laser scanning systems, as well as Renishaw’s soon-to-be-released dedicated marine laser scanning solution, via a dedicated driver. Throughout the data workflow of the NaviSuite solutions the laser scanning data is treated as any other sensor data type, acquired via NaviScan, edited in NaviEdit and visualised in NaviModel. A key feature of the software is that it supports all technologies and sensors that may be relevant to the customer's survey spread. Enabling integration in all the relevant NaviSuite solutions was an obvious task to undertake, according to EIVA Software manager... (read more)

Fugro Expands High-resolution Subsea Laser Scanning

Fugro has expanded its services for the offshore oil & gas sector with the addition of high-resolution subsea laser scanning. This specialist technology can be applied to a wide range of subsea services including metrology, field mapping, structure mapping, change detection and integrity management. Fugro’s Marine Construction Survey group based in Houston, Texas, USA, recently used subsea laser scanning in a number of successful projects in the Gulf of Mexico, including metrology and asset mapping. According to Fugro these projects delivered datasets that are un-matched by existing subsea technology. With subsea laser scanning, clients have an opportunity to gather high-resolution...

Dynamic Laser Scanning Set to Innovate Metrology Techniques

In December 2016, DOF Subsea (DOF) conducted a demonstration of dynamic underwater laser scanning as a replacement for traditional metrology techniques at The Underwater Centre in Fort William, Scotland. The demo showcased 2G Robotics’ and Sonardyne’s complete dynamic survey solution. The solution integrates 2G Robotics’ underwater laser scanner, the ULS-500 PRO, with Sonardyne’s inertial navigation sensor, SPRINT; Syrinx DVL and 6G acoustics. Seatronics, channel partner for 2G Robotics and provider of Sonardyne rental equipment, provided sensors and project/technician support. LBL and Photogrammetry Historically, metrology campaigns using Long BaseLine (LBL) acoustics and photogrammetry have demanded significant vessel and ROV time. Additionally, LBL... (read more)

Newton Labs’ Underwater Laser Scanners with Two Scanning Modes

Newton Labs' M series of underwater laser scanners can be utilised for area scans or as a fixed-line scanner coupled to an IMU/DVL for long-distance scans such as pipelines and umbilicals, etc. The same scanner can be used for high-resolution area scans and dynamic field scans at the push of a button on the user interface. The Newton Labs marine underwater laser scanners can now operate with a fixed laser line – continuously recording scan data as the line is moved across the targeted area. Operators can fulfil increased inspection demands with one laser scanner.  Newton sells underwater scanners offering... (read more)
