Focus: Unmanned Systems

Unmanned Systems 2017 200 Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in Hydro International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for July 2017 is:

Hydrography uses them in various ways that we assume to be familiar: Autonomous Underwater Vehicles (AUVs), ROVs, Maritime Autonomous Systems (MAS), Unmanned Surface Vehicles (USVs). They serve many applications – the choice of articles may be of inspiration for yours!

You can also read the 2016 Unmanned Systems Special magazine.

Sharing the Wealth

Autonomous Underwater Vehicles (AUVs) and associated undersea technologies have demonstrated exceptional current utility and great growth potential for military, governmental and commercial maritime agencies as well as for ocean research institutions. While sustained and agg... (read more)

Mapping a Hyper-acid Crater Lake with a USV

The 2,708m-high Poás Volcano is one of the most active volcanoes in Costa Rica, located 35km northwest of the capital San José. This stratovolcano contains a 300m-wide crater lake called the Laguna Caliente (‘hot lagoon’) filled with naturally hot,... (read more)

Coastal Monitoring of Water Quality

The wave-propelled AutoNaut unmanned surface vessel (USV) completed a short trial off the south-west coast of England to monitor the water quality by a sewage outfall. AutoNaut demonstrated its ability to reliably operate in shallow waters whilst also recording and transmitt... (read more)

Underwater Wireless Video Communication

This article presents the development, production and testing of wireless underwater acoustic video communications, which is unique in the world today. It also discusses the implementation of this technique on Autonomous Underwater Vehicles (AUV’s) to perform inspectio... (read more)

Unmanned Mapping of Ultra-shallow Waters

Hydrographic surveying in ultra-shallow, inland and enclosed waters can prove extremely challenging and often presents increased risks and obstacles to both personnel and equipment. These considerations include health and safety issues, potential damage to equipment, lack of... (read more)

Autonomous Underwater Vehicles

This last year has seen an increase in Autonomous Underwater Vehicle (AUV) sales and prospects for new sales. The lower than usual oil price may be responsible for much of that growth. Faced with operating in an increasingly harsh market where cost efficiencies can be the di... (read more)

Bering Strait ASV Deployment

TerraSond, a hydrographic services company based in Palmer, Alaska (USA), utilised an unmanned Autonomous Surface Vessel (ASV) to assist with the acquisition of survey data in July of 2015 in the northern Bering Strait region of Alaska. The 12’ ASV, a military target d... (read more)

Lessons Learned From the AF447 Search

It was a rainy day at Woods Hole, Massachusetts, USA. The scenery reminds me of the Twin Peaks atmosphere. I am about to interview Mike Purcell, the man whose search team finally found the wreckage of flight AF447 in the deep ocean in 2011. Only five years after this tragedy... (read more)

Furthering Ocean Science Using Innovative Marine Robotics

Robotics and autonomous systems are championed as one of the UK government’s ‘Eight Great Technologies’. The National Oceanography Centre is committed to maximising this technology to further ocean science and has purchased a fleet of innovative autonomous... (read more)

Handling Sonar Data from AUV Operations

During the past few years, autonomous underwater vehicles (AUVs) have established a greater presence in the hydrographic survey market and in the collection of oceanographic environmental data. These vehicles can transit nonstop for long periods of time, and can work in area... (read more)

Snow Crab Tracking Using Wave Gliders

Coastal communities around the globe are seeking better ways to understand and manage regional ecosystems. They depend on the ocean to sustain economic opportunities, ensure food security and safeguard fragile environments and species. For harvesters, scientists and governme... (read more)

Much More Than a Typical Hydrographic Office

In October 2015, Capt Brian D. Connon assumed the role of director of the National Geospatial-Intelligence Agency’s Maritime Safety Office. The organisation is an important, although not always visible, link in the global maritime safety chain. Its work contr... (read more)

How to Save Time in Offshore Survey Operations

In many instances, offshore survey work is carried out in connection with the construction of, for example, pipelines. The operational scenario is often a string of events where one task has to be completed before the next can be started. This article outlines the increased... (read more)

Hydro Dam Inspection by ROVs

The inspection and maintenance of vital resource facilities is an integral part of any regional health and stability management programme. Providing consistent quality output whilst reducing inspection and maintenance costs is key for those involved in the provision of such... (read more)

Inevitable Truths of Operating AUVs

Earlier this year, the US Navy deployed a Bluefin-21 Autonomous Underwater Vehicle (AUV) to search for the missing Malaysia Airlines Flight 370. The tragic disappearance was thought to have occurred over 1,600 kilometres offshore Perth in a remote and very deep region of the... (read more)

Autonomous Vessel Delivers in Challenging Environment

The hydrographic survey industry is changing and moving away from manned operations in an effort to reduce costs and increase safety. During the Shallow Water Survey 2015 conference this new approach and the associated challenges were assessed by Swath Services during the co... (read more)

Oceans of Earthquakes

Globally, the proliferation of sensors and resultant explosion of data is growing at exponential rates. Every digital device and sensor is expected to be available day/night to provide instantaneous results. This is possible if sensors are land or space based. This is not th... (read more)

AUVs in Hydrography

The US Navy and the Naval Oceanographic Office (NAVOCEANO) are committed to realising the vision that Autonomous Underwater Vehicles (AUVs) are available, affordable, and can play a critical role for many applications. Working in partnership with NAVOCEANO and the Office of... (read more)
