The offshore oil and gas industry has been investigating innovative solutions to help reduce or eliminate carbon footprints subsea and increase worker safety on- and offshore. Remote operations coupled with advanced autonomous solutions can have a significant impact on how business is conducted.
Why use a 90 m vessel for multiple surveys on a subsea pipeline when you can get the job done in a single pass, using a small electric powered remotely operated vehicle (eROV) launched from an uncrewed surface vessel (USV)? Depth of burial (DOB) inspections and surveys on pipelines are about to become faster, safer and more cost effective.
A sophisticated package of electromagnetic sensors developed by Norwegian company Argeo is radically improving the monitoring of power cables, pipelines, and wind turbine foundations, the scanning for buried UXO, and the mapping of deep-sea minerals.
The methodologies in performing subsea inspection, maintenance, and repair (IMR) services are ever evolving, with new and innovative technologies rapidly advancing the capabilities of what is possible in the underwater domain.
Seoul-headquartered wave energy developer INGINE is set to celebrate its landmark 10th anniversary this year as its technology edges ever closer to commercialization.
Buoys equipped with hydrophones and acoustic recorders are used to evaluate the level of underwater noise on offshore wind farms. In recent years, the presence of certain species of marine mammal during offshore infrastructure works (pile driving, drilling, etc.) has been a major environmental concern.
The ocean sector is rapidly evolving as green energy demand fuels incredible growth in offshore wind. It is becoming evident that the technologies and methodologies historically used in the offshore industry to monitor and maintain assets must also evolve to address new inspection challenges and tighter cost constraints.
Offshore energy assets are, by their nature, expensive to maintain. Traditionally, operators perform regular ROV inspections to monitor the condition of subsea infrastructure in a timely and controlled manner.
