ASV’s C-Worker 7 Goes to Work for Subsea 7

A 7-meter autonomous surface vessel (ASV) was recently deployed to support offshore services provider Subsea 7 during pipelay operations off the coast of Egypt.   The C-Worker 7 vehicle manufactured by U.K. firm ASV Global was fitted with a survey suite comprising a multibeam echosounder and side scan sonar in order to carry out touchdown monitoring in support of the pipelay vessel Seven Antares.   A custom payload frame was designed to house the survey suite specified for the mission. The modular frame slotted into the C-Worker 7’s moonpool to mount and deploy the sensors. Extensive

Scientists Study Largest Underwater Volcanic Eruption

In July 2012, airline passengers flying over the Southwest Pacific Ocean spotted a large and unusual object floating on the water’s surface.    That object, which turned out to be a giant raft of pumice, was evidence that an underwater volcanic eruption had occurred. And as the raft continued to grow to roughly the size of Philadelphia, scientists observed that the eruption was extraordinarily large.   The eruption had occurred at the Havre volcano northeast of New Zealand, and was the largest to take place underwater in the past century.   “We knew it was a

Finding Monsters on the Ocean Surface

The study of extreme wave events in the ocean has become a popular area of research in recent years. Aside from seafarers, extreme waves impact coastal communities and are of great interest to marine renewable energy companies. This is particularly prevalent in the face of coastal erosion, rising sea levels and uncertainty in how the wave climate will change in a warming world. However, much of the current research is based on modeling and experiments. Extreme wave events – including storm waves, rogue waves, storm surges and tsunamis – are rare, and as such are difficult to observe and

Unmanned Vehicles In, On and Above the Water

As part of the annual BlueTech Week in San Diego, attendees were given an opportunity to see several unmanned vehicle technologies in action.   The main event was put on by a team consisting of Marine Advanced Research, Inc.; Planck Aerosystems, Inc.; and Teledyne Marine, Inc. (all with bases in California). Together, the team demonstrated multi-interoperability among five different unmanned systems on the water, in the air and subsea. A Z-Boat 1800RP unmanned surface vehicle (USV) from Teledyne Oceanscience used Odom MB2 multibeam sonar technology to search for and inspect targets of interest

Rovco Wins Gwynt y Môr Windfarm Contract

Rovco has been awarded a three-year contract to support one of the world’s largest offshore wind farms, Gwynt y Môr, eight miles off the coast of North Wales in the U.K.    The U.K. subsea company said it will provide its underwater ROV 3D visual survey solution, alongside traditional video, blueview sonar and cathodic protection analysis techniques.   Gwynt y Môr consists of 160 turbines that generate enough energy for more than 400,000 homes across the country. It extends over an area of about 80km² and includes two offshore substations and 134kms of onshore

Unique Tech Helps Monitor Underwater Volcano

 Helping the Spanish Institute of Oceanography (IEO) and both Canarian Universities to closely monitor the underwater volcano Tagoro off the coast of El Hierro Island in the Canary archipelago, RTsys has designed a combined seismic and acoustic system especially for the project.   RTsys designed a system combining three geophones – two pointing horizontally and one vertically – to measure ground movement in the area. A hydrophone was added to record the noise caused by the ground or by bubbles in the water formed by vibrations.    Submerged in October 2016, the

propulsion system to allow for deep dives and long range duration.   “The world’s oceans present a wide range of tasks and questions that cannot yet be addressed because we don’t have the appropriate vehicles and systems," said Marc Schiemann, project manager at thyssenkrupp Marine Systems. "MUM offers a wealth of new options for industrial marine engineering and scientific ocean research. We will equip the floating, wireless underwater vehicle with an air-independent fuel cell propulsion system. Our goal is to develop a vehicle which allows diving depths of up to 5,000m

James Fisher Subsea Excavation Completes Project in Taiwan

Global subsea excavation specialist James Fisher Subsea Excavation (JFSE), a part of James Fisher and Sons plc, said it has completed its first project in Taiwan.    Experts from the mass/controlled flow excavation (M/CFE) provider deployed the shallow draft Twin R2000 tool to de-bury and retrench a cable for maintenance as part of the prominent Formosa 1 wind farm development for its client, cable lay contractor Woen Jinn Harbor (WJH).   The Twin R2000’s non-contact method and ability to operate in very shallow water depths was critical to the success of the excavation which
