Advances in High-speed Underwater Remote Vehicles for Subsea Pipeline Inspection

The Benefits and Challenges of the Technological Revolution in the Pipeline Survey Industry
The pipeline survey industry has undergone a technological revolution in the past couple of years, and the consequential benefits and challenges are only just beginning to be fully realized. The cost efficiency of subsea operations has been one of the key focus areas of the offshore energy industry in recent years. This focus, combined with increased growth in the amount of subsea infrastructure now in-situ on the seafloor, has seen a rising need for innovative approaches to subsea asset inspection. These solutions need to be cost-efficient, maintain data quality, and be able to provide a platform that supports future technologies.... (read more)

AUV and ROV Technology Plays Key Role in Historic Discovery

WWII Wreck Located in South Pacific
An underwater research and exploration vessel has played a key role in locating a major US aircraft carrier lost during World War Two. The R/V Petrel, owned and operated by philanthropist Paul Allen, discovered the remains of the USS Hornet on the seabed, 5,330 metres below the surface of the South Pacific Ocean near the Solomon Islands in late January 2019. This article looks more closely at the importance of underwater technology in enabling this historic find. The R/V Petrel is an expedition ship belonging to Vulcan Inc, a company founded by explorer and philanthropist Paul G. Allen, co-founder of Microsoft... (read more)

Depth of Burial – Galloper Offshore Wind Farm

Galloper Offshore Wind Farm is a 353MW wind farm project located 30km off the coast of Suffolk, UK. It is now in full operation and each year will generate enough green electricity to power the equivalent of more than 380,000 British homes. The construction of the wind farm created almost 700 UK jobs and its operation has created around 90 direct and indirect long-term jobs in the local area. A 60-strong team will operate and maintain the wind farm day-to-day from a base under construction in Harwich International Port. There are 56 wind turbine generators (WTGs) located in water depths... (read more)

Sonar Plays Integral Role in First Human Reaching Deepest Point in Atlantic

Kongsberg Maritime has announced that the EM 124 sonar, installed aboard the DSSV Pressure Drop, played a key role in the deepest solo human submersible dive completed by the Five Deeps Expedition. Expedition founder and submersible pilot, Victor Vescovo, reached the bottom (depth of 8,376 metres) of the Puerto Rico Trench in his private submersible, the Limiting Factor, following precision mapping of the ocean floor completed by the EM 124. The Kongsberg EM 124, released in 2018, is the fifth generation multibeam system from Kongsberg Maritime and the successor of the EM 122. It is a modular multibeam echosounder that... (read more)

ASL Announces Next Generation in Acoustic Backscatter Measurements

A new tool to measure both sediment concentration and sediment size are being built by ASL Environmental Sciences (ASL). The Multi-frequency Ultrasonic Device (MUD) is based on ASL's successful Acoustic Zooplankton Fish Profiler (AZFP). The MUD and AZFP echosounders can be configured with up to four frequencies ranging from 38 kHz to 2 MHz. The MUD prototype is based on a set of higher frequencies (200 kHz, 769 kHz, 1.2 MHz and 2.0 MHz) that will allow for a broad range of particle size discrimination. While the AZFP is a high gain device for low scattering conditions and the greatest... (read more)

Fugro Receives Award for Efforts to Close Seabed Mapping Data Gap

Fugro has received the Marine Technology Society (MTS) 2018 Compass Industrial Award for outstanding private sector contributions to marine science and technology. In selecting Fugro for the honour, MTS cited the company’s legacy of marine survey innovation and its industry-leading support of The Nippon Foundation-GEBCO Seabed 2030 Project (Seabed 2030). David Millar, Fugro’s government accounts director for the Americas region, accepted the award. “We are grateful to MTS for recognising our efforts with Seabed 2030. Given that a significant proportion of Fugro’s work is ocean related, supporting this project is a way for us to positively impact global society and... (read more)

Hydrographic Surveying: Where Do We Stand?

The Ever-increasing Accuracy of Mapping Surface Waters
Hydrographic surveying is highly specific and requires a suite of advanced acquisition and positioning sensors attached to a mobile survey platform as well as sophisticated software to allow the correct combination of all the data. For those in the industry, the advances over the last decade may feel more like an evolution rather than a revolution. If we look back one, two or even three decades, we can see the enormous leap that hydrographic surveying has taken. Where do we stand, and what can we expect for the near future? In this article, we will look at the present compared... (read more)

Two MVP30-350 Systems for Geological Survey of Ireland

The Geological Survey of Ireland (GSI) has purchased AML Oceanographic’s Moving Vessel Profiler (MVP) to simultaneously improve the productivity, safety, and data quality of their survey operations. Working in partnership with the Marine Institute of Ireland under the joint programme INFOMAR, they have committed to having all Irish waters mapped by 2026. The addition of MVP30-350 systems to their two 16m survey catamarans is expected to facilitate on-time completion of the project. “The MVP is expected to improve productivity by over 10%, but more importantly they will enhance safety,” explained Project Manager Sean Cullen. "Instead of having crew members venture... (read more)
