Autonomous Seabed Transponder Calibration

ASV’s C-Worker 6 successfully carried out a seabed transponder calibration in 1,300m-deep waters. The sea trials, which took place in the Gulf of Mexico, were conducted in rough conditions with 2.5m waves. ASV technical sales manager Brian Anderson said that this unmanned capability could save the oil and gas industry millions of dollars. The ability to conduct precise subsea positioning in challenging conditions broadens the possible applications for C-Worker. C-Worker is the world’s first unmanned oil and gas workboat. ASV designed and built the 6m vehicle at its waterside facility in Portchester, UK. ASV has completed the build of a... (read more)

Echo Sounder Calibration Tool

HydroBar is a hydrographic tool for calibrating survey echo sounders during field surveys. A real-time sound velocimeter is combined with a sonar target (‘bar’) and Windows-based software which can run on a PC in the background of Hypack, HydroPro or other hydrographic software. In CAST (Profile) mode, an integral depth sensor enables the HydroBar to display and record sound velocity and temperature vs. depth. All data will be stored in a .VEL file for direct input into Hypack. In BAR CHECK mode, the software menu guides the user through simple steps to perform a bar check. Data is stored in... (read more)

ECDIS Colour Calibration Panel Computers

The MPC-122-K marine panel computer is IP67-rated and ECDIS compliant with colour calibration capability. The panel features full-range dimming, optical bonding (optional), a wide viewing angle and colour calibration (ECDIS-compliant).     The design is compliant with many industrial marine standards, such as IEC 60945, DNV, and IACS-E10, and the IP67-rated enclosure provides additional protection against harsh marine environments. Moxa has created a dedicated website with information about the need for colour calibration for ECDIS, the ECDIS-type approval process, what distinguishes the colour calibration of Moxa Displays, why the Moxa MPC-122-K has an IP67 enclosure and the outstanding system-wide thermal...

ECDIS Display Repair and Calibration Authorisation

Sperry Marine North American Support Center in Harvey (LA, USA) is now authorised to perform Level III repair and calibration of Hatteland flat-screen monitors for electronic chart display and information systems (ECDIS).   The Level III certification means that the Sperry Marine facility can now perform ECDIS calibration requirements mandated by the International Maritime Organization (IMO) for the Hatteland products. The Hatteland flat-screen LCD monitors are used in Sperry Marine's new-generation VisionMaster FT series of radars, ECDIS and TotalWatch multi-function workstations.   The repair activity is defined and supported by a formal service agreement between Sperry Marine and Hatteland Display...

OSIL's Dynamic Calibration Laboratory Well Used


OSIL are now responsible for the calibration of over one thousand instruments in their dynamic, high precision calibration laboratory. The regular calibration of monitoring instruments is required to ensure that the instrument is working within the manufacturer's specification and providing the highest quality data possible. Typical instruments that OSIL calibrate include Salinometers, CTDs and SVs and Multiparameter Sondes.   OSIL Director, Richard Williams, explains, "Our calibration lab and the services we offer to the industry and going from strength to strength. Our lab is fully ISO 9001:2000 accredited, which gives our customers a level of service that they can trust." ... (read more)

Ashtead Technology Invests in Calibration Laboratories

Subsea equipment rental company Ashtead Technology, UK, has made an investment in order to operate established equipment calibration facilities in all its office locations. In addition to the standard range of product calibration services, the Singapore and Aberdeen branches offer the ability to calibrate depth, temperature, conductivity and sound velocity equipment to manufacturers' standards. These calibration facilities have been audited and approved by Valeport Ltd (UK), a manufacturer of oceanographic instrumentation for the survey industry. Ashtead engineers have undergone specialist calibration training at Valeport, Ocean Scientific and Tritech. The labs have been developed in close collaboration with these manufacturers to...

Digital Hydrophone Calibration Lab Officially Opened

A new digital hydrophone calibration lab has been commissioned at the Ocean Sonics office in Great Village, NS, Canada. The traditional analogue approach to calibrating hydrophones is a tricky and demanding task. Digital hydrophone calibration greatly simplifies the calibration process. The separate wood-framed lab sits above the ground to isolate it acoustically. A Faraday cage shields instruments from electromagnetic radiation that could interfere with low signal measurement. Power is isolated from the main building and the data is wired to the main building to allow remote operation. The lab facility features a large test tank with room to fit multiple... (read more)

New Calibration Capabilities in HIPS and SIPS

Teledyne CARIS has released HIPS and SIPS 10.4. This version introduces the first commercial release of CIDCO’s Automatic Boresight Calibration tool, providing a systematic approach to calibration as an alternative to the traditional, manual patch test. Borrowing adjustment techniques from the Lidar industry, the Multibeam-IMU Automatic Calibration (MIBAC) algorithm developed by CIDCO is now available in HIPS. The Automatic Boresight Calibration tool is designed to simplify both survey planning and post-processing for calibration requirements, requiring fewer survey lines in the field and providing a repeatable, robust calculation of the boresight angles between the IMU and sonar in post-processing in just...
