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.

Must Read

Can I Communicate with My AUV?

The prospects for an increased future use of autonomous underwater vehicles (AUVs) in the Maritime & Offshore sector are high, mainly due to the search for cost effectiveness. AUVs reduce the need for large crews, divers and vessels in the operational area. AUVs are alre... (read more)

Mapping the Floor of Upper Loch Linnhe Using AUVs

Due to their particularly shallow and turbulent thermocline, conducting seafloor mapping in lochs, fjords and other estuaries always presents a unique challenge to the hydrographic surveyor. Surface vessels often struggle to obtain accurate measurements due to the highly var... (read more)

Unmanned Systems

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)

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)

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)

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)

“We Are Limited by Imagination Rather Than Technology”

Now that the spotlights are on unmanned vehicles for various tasks in subsea survey, inspection and maintenance, it’s interesting to see how two businesses are looking at the technology. In 2016, Kongsberg and the start-up Eelume started their cooperation to develop an... (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)

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)

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)

Unmanned Systems

USBL in Dam Survey by ROV

An USBL underwater positioning system is the ideal solution for dam survey by ROV, providing easy and fast set-up and accurate 3D measurement for traceability, but not all USBL systems can meet the demands of this environment. PLSM (France) has developed a light and polyvale... (read more)

Bering Sea ASV Force Multiplier

TerraSond, a hydrographic services company based in Palmer, Alaska (USA), used a C-Worker 5 (CW5) unmanned autonomous surface vessel (ASV) in conjunction with a 105’ (32m) research vessel from June through August 2016 on a major hydrographic survey in the Bering Sea re... (read more)

USVs Developing into Versatile Tools

Unmanned surface vehicles (USVs) are gaining terrain in hydrographic surveying. They combine the advantages of small survey vessels with those of unmanned survey platforms, giving them a range of applications that is likely to expand even more. They enable hydrographic... (read more)

Autonomous Vessel as Enforcer

There are currently 13,764 Marine Protection Areas (MPAs) jointly covering over 2% of the oceans. One such MPA is Malaysia’s newly formed Tun Mustapha Park comprising 1 million hectares of marine park and shark sanctuary in northern Borneo. Governance, management, effe... (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)

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)

Discovering H.M.S. Ark Royal

In November 1941 the aircraft carrier H.M.S. Ark Royal was returning from Malta, when it was torpedoed and sunk by a German U-boat southeast of Gibraltar. Its destruction was a devastating blow to the Royal Navy's power in the Mediterranean theatre of war and to the morale o... (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)
