Scripps Chooses Hydrins

The Scripps Institution of Oceanography, based in San Diego, California, USA, has chosen IXSEA technology for a key aspect of its marine survey activities. The Institute has fitted a Hydrins inertial navigation system (INS) to its research vessel Roger Revelle to provide information about the motion and position of the vessel when gathering multibeam sonar data. Rick Morton, IXSEA's North American Sales Manager-Geosciences, said:"This is repeat business with one of the world's best-known oceanographic organisations. The new Hydrins is a replacement for an earlier unit and incorporates several subtle performance enhancements, the result of a continuing equipment development program at... (read more)

C-Innovation ROVs on Track

C-Innovation, UK, has placed a major order for SPRINT inertial navigation systems (INS) from Sonardyne International Ltd. Working closely with C-Innovation to understand the requirements when using Schilling’s UHD ROVs in  operations, SPRINT has been fully integrated into these ROVs, including the use of specialised Seanet connectors. This resulted in a tested, standardised configuration that supports a dedicated AHRS or INS output direct to the ROV with an automatic mode switch. A configuration that allows the system to be used as both a high-performance AHRS for typical ROV guidance or as an INS that provides automatic station keeping capability for... (read more)

A Comparison of Five Main Metrology Techniques in Use Today

IMCA Guidance on Subsea Metrology
Subsea metrology is the process of acquiring accurate measurements for the connection of subsea structures and pipelines. IMCA’s guidance covers the most commonly used techniques today. These are long baseline (LBL) acoustics, both diver taut wire and digital taut wire, photogrammetry and inertial navigation systems (INS). This article covers basic principles, along with engineering requirements, different methods and technologies, and some of the advantages and limitations for each technique. The objective of subsea metrology is to determine accurately the relative horizontal and vertical distance between subsea assets, as well as their relative heading and attitude. Absolute positioning is not necessary... (read more)

Subsea Navigation for Pipelay Vessel LV 108

Sonardyne, based in Houston, USA, has supplied acoustically aided inertial navigation technology to offshore engineering, procurement, construction and installation company McDermott International for its Lay Vessel 108 (LV 108). The Sonardyne Ranger 2 Pro DP-INS system, the highest specification available from Sonardyne, is being used to support touchdown monitoring surveys of submarine cables, umbilicals and pipelines and as an independent position reference for the LV 108’s Kongsberg dynamic positioning (DP) system. McDermott’s LV 108 entered service in 2015 and is currently on contract in the Ichthys field, Western Australia. Designed as a fast-transit, dynamically positioned (DP 2) vessel for subsea...

Two Additional Gavia Offshore Surveyors for UTEC Survey

Teledyne Gavia from Iceland has received an order for two additional 1,000m depth-rated Gavia Offshore Surveyor Autonomous Underwater Vehicles (AUVs) to UTEC Survey (USA). The UTEC Gavia AUVs are fully equipped for geophysical surveys in near-shore environments out to 1,000 metres. The vehicles are fitted with swath bathymetry, sidescan sonar, subbottom profiler modules and a depth-rated camera with strobe lighting. The two most recent vehicle purchases come with the DVL aided ROVINS154 Inertial Navigation System module (iXBlue, France), providing a high accuracy INS in a package that is not of US origin so it does not automatically come under the...

DP Reference Technology Upgrade for Noble Globetrotter I

Offshore drilling contractor Noble Corporation PLC has selected acoustically aided inertial navigation technology from Sonardyne Inc., Houston, for its ultra-deep water drillship Noble Globetrotter I. The Marksman DP-INS system is being used to provide a high-integrity, independent subsea position reference for the vessel’s GE DP3 dynamic positioning (DP) system as it drills exploration wells in water depths up to 10,000 feet. Built in 2011, the Noble Globetrotter I is significantly smaller than a conventional drillship but has the same operational capacity. The reduction in size has been achieved through design features such as a hoistable drilling floor, multi-purpose tower and... (read more)
