Wireless subsea technology is becoming a fundamental part of the oil and gas industry worldwide. Back in 2010, Woods Hole Oceanographic Institution (WHOI) scientists and engineers announced testing of an undersea optical communications system that, complemented by acoustics, enabled a virtual revolution in high-speed undersea data collection and transmission. Acoustic techniques were developed, which are now the predominant mode of underwater communications between ships and smaller, autonomous and remote control vehicles. However, acoustic systems, although capable of long-range communication, transmit data at limited speeds and delayed delivery rates due to the relatively slow speed of sound in water.

Accessing to the world’s deepest ocean trenches has always been challenging and these have only been reached sporadically, leaving these areas virtually unexplored. The Woods Hole Oceanographic Institute’s (WHOI) Nereus, a proof of concept Hybrid Remotely Operated Vehicle (HROV), now being used on Schmidt Ocean Institute’s (SOI) Falkor and other research vessels, offers unprecedented access to the deepest regions for scientists, enabling systematic exploration and studies of deep trenches. There are a number of deepsea trenches at hadal depths around the globe worth exploring, highlighting to WHOI and SOI that they would have an exceedingly large area to cover with a single HROV.

Remotely Operated Vehicles (ROVs) perform a wide range of tasks in a variety of underwater scenarios ranging from research to offshore oil industry support, military operations and S&R. Technological developments, have greatly enhanced their scope of operation including harsh environment operations, such as deepwater and Arctic ops. As oil operations went to deeper waters, so did ROVs, which became a key asset in subsea operations such as pre-salt development and has also been increasingly substituting divers below 300 meters, although saturation diving is very much alive and will also continue to be an important asset. The ROVs of the future will have increased intelligent autonomous behavior and will use logic driven circuitry for routine tasks like turning valves…

An international team of researchers is using the unique deepwater Hybrid ROV Nereus, and other advanced technology to explore life in the depths of the Kermadec Trench, which runs northeast from the North Island of New Zealand. The 40-day expedition, which began on April 12th, kicks off an ambitious three-year collaborative effort funded by the National Science Foundation (NSF). The goal of the project, known as Hadal Ecosystem Studies (HADES), is to conduct the first-ever systematic study of life in ocean trenches, comparing it to the neighboring abyssal plain at depths between 3,000 and 6,000 meters. Due to the extreme pressures of these deep-sea environments and the technical challenges involved in reaching them…

Offshore Ocean Observatories, are composed of suites of surface and subsea instruments and sensors with long-term power supplies and permanent communications links that can feed data to scientific laboratories in real-time. Motivated by advances in computing, telecom, marine architecture and subsea sensor technology, researchers observe the oceans in real-time, for long periods of time, and sky around all the way to deepwater, including imaging and continuous sensor observation along the whole water column to the sea floor. Ocean observatories are designed to answer questions about how the seas and oceans work, their dynamics and peculiarities.
