Van Oord Deploys Giant Trencher to Bury Offshore Wind Cables in North Sea

Dutch offshore installation contractor Van Oord has deployed a large remotely operated trencher called Deep Dig-It off the Dutch coast to bury offshore wind farm cables 5,5 meters deep into the seabed.The trencher has been deployed as part of the cable installation project for the Dutch grid operator TenneT's Hollandse Kust (zuid) offshore grid construction to connect new offshore wind farms, which will see four cables buried in the North Sea.For the first ten kilometres of the cable route at sea, the cables will have to be buried more than 5,5 meters into the seabed to safely cross the busy

SMD Wins Subsea Plow Order

UK-based subsea vehicle manufacturer Soil Machine Dynamics (SMD) has secured a new contract to deliver a subsea plow to a subsea cabling company.SMD said Thursday that, as part of the contract, it would supply its MD3-XT plow, capable of trenching up to 3.3 meters with jetting, at depths of up to 1,600 meters. As for the client, SMD didn't say who it was, just describing it as "a leading global subsea cabling company."The contract includes the installation and commissioning of the complete turnkey system including launch and recovery systems (LARS). The MD3‐XT plow is used in telecoms

Robotics: Autobots Transform in the Offshore Energy Sector

Robots and robotics have slowly been entering our lives, in various shapes and forms (and fictional characters), from self-driving household vacuum cleaners to highly automated manufacturing systems. Now they’re heading for the offshore world – in just as many shapes and forms.There could be a lot to gain from robotics, but platforms and offshore wind turbine structures are also very challenging places to put them on. For oil and gas, key drivers are around safety and cost . For the offshore wind sector, the sheer volume of structures being installed is driving a push for robotic systems

The Troubled History of Protecting Marine Assets

The history of protecting marine assets is a tale of endless perseverance. From the moment humans have put infrastructure in the water, it has been damaged by other humans. Despite incredible advances in technology and installations, incidents still occur at an unacceptable rate. The types and volume of marine assets have exploded since the 1850s when the first submarine telegraph cables were laid. Today oceans, seas and lakes are the home of thousands of cables, tens of thousands of miles of subsea pipes, and countless underwater storage tanks. Above surface, assets are also still at a surprising

Fast-moving Waterfalls in the Deep Sea

New research led by the National Oceanography Center (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behavior of submarine channels. These underwater channels are the offshore equivalents of rivers, but can be much larger. Submarine channels can extend for tens to thousands of kilometers offshore, providing an important conduit for the transfer of sediment, nutrients and pollutants, such as microplastics, to the deep-sea. Avalanches of sediment that flow down these channels also pose a hazard to networks of seafloor cables that underpin global communications,

Marine Autonomy Above & Below the Water

Marine autonomous systems and combinations of such systems are being increasingly put to the test in the offshore space. Elaine Maslin looks at how hybrid remote and autonomous systems are now being tested.Concepts like resident subsea vehicles, for inspection, repair and maintenance, are attractive options, but not the only ones being tried. Deploying remotely operated vehicles (ROVs) from unmanned surface vessels (USVs) are also being tested and put to use. It’s another way to take operators out of harm’s way, centralize operations and cut costs and environmental footprints. But, there&rsq

Seiche Unveils Acoustic Monitoring Technology

for seabed, rising cable, or suspended cable deployment.Providing enhanced metrology, the instrumented hydrophone has applications spanning underwater noise measurement and environmental use for Port and Harbor Authorities, including compliance with environmental legislation, through to recording of marine mammals, generic noise pollution, and identification of individual vessel sound signatures at sea, which are of value to the maritime and defense sectors.The new Hydraq QQ1000 sensor meets the challenges of accurately measuring radiated noise and man-made noise pollution in the marine environment

Uptick for Subsea Tree Installs Coming

Increasing activity, led by scaled down, accelerated projects and subsea tiebacks is helping drive an increasing business in the subsea industry. But there’s slim chance of revisiting the boom days of 2013, the Society of Underwater Technology’s annual Global Subsea Market Outlook Business Breakfast heard this morning.Henning Bjørvik, an analyst in the Oilfield Service team at Rystad Energy with a primary focus on the subsea market, says that in 2022-2023, close to 400 trees are expected to be installed. But, that’s still short of the industry’s peak activity in 2013.

PSW Takes Over EMAS Spoolbase In Norway

Norway's PSW Group has taken over the operation of the former EMAS spoolbase located in Gulen Industrial Harbor, Western Norway. In a statement on Wednesday, PSW Group said the agreement to take over the spoolbase covered all activities related to the production and spooling of pipelines for offshore use. The spoolbase will be named "PSW Spoolbase".The spoolbase capable of handling a wide range of subsea and offshore piping projects in Northern Europe has a 3700m2 fabrication facility including an integrated indoor tie-in area. It was constructed in 2014 to optimize logistics and

Fugro Takes Over Seabed Geosolutions

Fugro announced on Monday it has entered into an agreement to acquire CGG’s 40% shareholding in Seabed Geosolutions and to terminate the Seabed Geosolutions’ joint venture agreement effective December 30, 2019 in exchange for a cash consideration of $35 million, paid by CGG before year-end 2019.Fugro said it remains fully committed to divest the Seabed Geosolutions business which is a non-core asset held for sale. It is expected that this transaction, which will result in Fugro becoming the sole owner of Seabed Geosolutions, will facilitate the divestment process.In line with CGG's
