Subsea Robotics for Renewables

As the global fleet of offshore renewables fleet increases, ways to reduce the cost and increase the efficiency and safety of operations and maintenance work, using robotics and autonomous systems, will also grow. Elaine Maslin reports.Robotics and autonomous systems are moving into many areas of modern day life. It’s becoming harder to avoid them, from our phones to automotive systems and now offshore energy renewable projects.Both are seen as tools to do otherwise dull, dirty or dangerous work, without human involvement, but also as a way to reduce operational cost and to produce more reliable

Meet the Future of Visualization and Mapping Sonars

The images below were generated in a single pass of the survey vessel, without any post-processing of the data required and significant detail around the piles is clearly visible.   The patented Echoscope range of real-time sonars are more than visualization tools, as they enable the capture of hydrographic quality data in real-time from the same sensor. This enables an operator to use the sonar for a multitude of purposes, such as visualization of a valuable asset as it is accurately placed on the seabed, and then simultaneously using this data to provide the as-built or as-laid survey.   The

Glider-Based Ecosystem Study

Fish Profiler (AZFP) 38, 125 and 200 kHz instrument in the Terra Nova Bay (Ross Sea, Antarctica).  The deployment lasted 3 weeks and the glider was recovered on January 31, 2018.     The purpose of this deployment was to obtain mesoscale and sub-mesoscale measurements of hydrographic processes and simultaneous biological distributions and abundance. From the resulting data, the researchers will examine the interactions between multiple trophic levels (phytoplankton, zooplankton and fish) and their relationships to the physical hydrographic driving forces such as sea ice and

NOAA Releases 2018 Hydrographic Survey Plans

Beginning in April, NOAA’s four hydrographic survey ships – Thomas Jefferson, Ferdinand Hassler, Rainier and Fairweather – will set out along with private contractors to tackle their assigned survey projects over the course of the 2018 field season.   Below are NOAA’s priority areas for planned survey projects 2018:   Alaska North Coast of Kodiak Island – Last surveyed in 1932, this survey project focuses on areas inadequate for safe navigation, particularly along the corridor of vessel traffic transiting from Kodiak.   West of Prince

Expanded Waterfront for Oi18

Visitors to Oceanology International 2018 (Oi18) at ExCel, London (March 13th-15th ,2018), will once again be able to participate in a series of live product demonstrations from the event’s waterside exhibitor area on the Royal Victoria Dock. As one of the most popular attractions for Oceanology International visitors, this year’s dockside and on-water demo programme has been expanded and will now comprise daily demonstrations to offer an even more valuable experience for those attending, whilst allowing exhibitors to share their product’s effectiveness in a marine environment.

University of Vienna Acquires New Multibeam Equipment

A project to create 3D models of pile dwellings in Austrian lakes thousands of years ago has resulted in the acquisition by the University of Vienna of a multibeam solution supplied by MacArtney.   The Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology is a research institute dedicated to the development of new techniques and methodological concepts for landscape archaeology. Its research program combines geophysics, aerial imaging, computer science and geomatics to develop efficient and universally applicable approaches for non-destructive detection, documentation

UKHO Creates High Density ENC of the Bristol Channel

The United Kingdom Hydrographic Office (UKHO) has disclosed details of a new Electronic Navigational Chart (ENC) which could help to improve situational awareness and safety.   Developed to cover an area of the Bristol Channel known as ‘The Bridge’, this ‘high density’ ENC displays depth contours at one-meter intervals, allowing ECDIS to set safety contours at corresponding levels to support navigation through shallow water.   ECDIS will select safety contours based on a safety contour depth value set by the mariner. As most charts contain depth contours at
