Kongsberg Maritime to Launch Next Generation HUGIN Endurance AUV

Kongsberg Maritime has announced the next generation of its advanced HUGIN Autonomous Underwater Vehicle (AUV). Named HUGIN Endurance, the new AUV boosts operational duration to approximately 15 days, enabling extended survey and inspection missions far from shore. This longevity allows HUGIN Endurance to undertake extensive missions without the support of a mother ship. Shore-to-shore operations offer the opportunity to reduce the carbon footprint for commercial activities and yet retain unrivalled data resolution and accuracy. With this in mind, Kongsberg has added its Maritime Broadband Radio (MBR) communications system to HUGIN Endurance’s payload, allowing it to surface and share large quantities... (read more)

Sub-bottom Object Detection

An Update on the Main Innovations of the Past Years
While nautical charting mainly focuses on bathymetry and objects that form a hazard to shipping, offshore construction and dredging require sub-bottom information. There is nothing worse in any project than finding wrecks or unexploded ordnance (UXO) after construction has started. The detection of covered cables and pipelines is also an important survey objective. There have been some interesting innovations in this field over the past years and, while this article does not attempt to be exhaustive, it provides an overview of the various types of system available. The Sub-bottom Profiler The classic instrument for detecting bottom layers and sub-bottom objects... (read more)

Applied Acoustics Launches Pyxis Integrated Inertial USBL System

Applied Acoustic Engineering (AAE) has announced the launch of its next-generation USBL system, Pyxis USBL. Taking its name from the constellation Pyxis Nautica – the mariner’s compass – Pyxis USBL combines the best of AAE’s subsea acoustic tracking technology with a highly advanced inertial navigation system (INS) from a respected name in the industry, to create a state-of-the-art, inertially aided Ultra Short Baseline system capable of accurate subsea tracking with survey-grade performance. The combination of AAE’s Sigma 2 acoustic protocols and SBG Systems' high-precision Navsight Apogee Marine INS brings together two leading names in the field of marine technology, resulting...

TDI-Brooks Maps the Liberty Ship Reef Site George Vancouver

TDI-Brooks recently mapped the Liberty Ship George Vancouver Reef off Freeport, Texas while out on a seabed survey project with the RV Brooks McCall. The multiple multi-phase geophysical and geotechnical site surveys programme consisted of pipeline routing and subsea structures to facilitate route and project design for offshore developers. Equipment used to map the ship was a Teledyne Reson SeaBat T-20 multibeam sonar with integrated Applanix POSMV for Motion. Applying the mesh tools to the multibeam survey shows an example of the shipwreck. Texas has been involved in artificial reef development for nearly 50 years. Numerous reef building materials have...

Submerged Munitions, No Hazard Left Undetected

Minimum Requirements for Munitions Detection at Sea
Munitions in the sea pose a risk to the sustainable development of the ocean economy. In particular, they are a global challenge during the construction of wind parks, pipelines and other infrastructure. To ensure high-quality performance during the execution of the necessary maritime munitions detection and clearance operations, industry experts and scientists from Germany have defined a set of requirements. These are particularly important in the detection phase which requires the attention of hydrographic surveyors. Safe access to large areas of the seafloor is a prerequisite for offshore economic development. However, this ability has been compromised by the presence of... (read more)

Hydrographic and Geophysical Surveys in Celtic Sea and Atlantic Ocean

Hydrographic and geophysical survey operations will be undertaken by INFOMAR in the Celtic Sea and the Atlantic Ocean between April and October this year, according to a recent marine notice from the Irish Department of Transport, Tourism and Sport. INFOMAR is a joint programme between Geological Survey Ireland and the Marine Institute, surveying unmapped marine territory and creating a range of integrated mapping products of the physical, chemical and biological features of the seabed. Covering some 125,000 sq. km of underwater territory, INFOMAR will produce integrated mapping products covering the physical, chemical and biological features of the seabed. Both Irish Marine Institute vessels,... (read more)

UTEC Completes Survey Subcontract for McDermott in the Middle East

UTEC, a global surveying company in the Acteon subsea services group, completed consecutive as-built and post-construction anchor debris clearance surveys using remotely operated vehicles (ROV) for McDermott International. The company mobilized a DP2 offshore support vessel in early December 2019 with work- and observation-class ROVs and a nearshore survey workboat for the as-built campaign. The anchor debris clearance campaign used the same vessel with a sub-bottom profiler, a side-scan sonar, a multibeam echosounder and a magnetometer. Geophysical Survey in Shallow Waters  “We are delighted to have completed these surveys,” said Nadir Rahmatullah, UTEC commercial director for Asia Pacific and the Middle East.... (read more)

India’s National Institute of Ocean Technology Signs Contract for AUV System

Kongsberg Maritime has announced that contracts have been signed for the sale of a HUGIN AUV system to the Indian National Institute of Ocean Technology (NIOT), located in Chennai, India. This sale has been conducted in collaboration with Kongsberg Maritime India, a subsidiary of Kongsberg Maritime AS. The HUGIN AUV system ordered by NIOT is rated to a depth of 6,000 metres and will be equipped with a KONGSBERG HISAS 1032 synthetic aperture sonar and EM2040 multibeam echosounder, designed for hydrographic and seabed classification applications. It will also carry a high-resolution colour still image camera, plus a range of environmental... (read more)

Silicon Sensing’s Technology Supports Autonomous Mayflower Voyage

Two Silicon Sensing Systems ultra-precise AMU30 inertial measurement units (IMUs) will provide critical navigation data to the autopilot capability for the Mayflower Autonomous Ship (MAS) throughout her milestone transatlantic voyage this autumn. Setting sail this September, the 15-meter long, 5-ton MAS400 will repeat the Mayflower’s original epic voyage made 400 years ago. Led by marine research organization ProMare and powered by IBM, she will sail from Plymouth, England to Plymouth Massachusetts, USA. Instead of a captain and crew, she will use computer vision, machine learning, cutting-edge technologies and sensors to navigate and detect hazards.   Silicon Sensing’s AMU30 devices will form...

TerraSond Completes First Geophysical Survey for Mayflower Wind

TerraSond, an Acteon company, has completed a high-resolution geophysical survey for Mayflower Wind, a joint venture between Shell New Energies US LLC and EDPR Offshore North America LLC. The two-month campaign, which began in July 2019, surveyed an area, 20 miles south of Martha’s Vineyard, Massachusetts, USA, that can support up to 1,600 MW of offshore wind. The wind farm is scheduled to deliver energy in the mid-2020s and has the potential to power up to 680,000 homes. The project is TerraSond’s first with Mayflower Wind.
