Underwater Wireless Acoustic Standard Will Improve Offshore Vehicle/Drone Communication
An international oil and gas industry network, Subsea Wireless Group (SWiG), has launched a new wireless acoustic standard to improve communication between offshore vessels and the vehicles used in underwater inspection, maintenance and repair.
SWiG addresses problems related to the increasing diversity of communication systems used by Autonomous Underwater Vehicles (AUVs). Its new standard, SWiGacoustic, provides a simple acoustic protocol that satisfies interoperability requirements, aiding seamless communication between platforms. R&D consultancy Sagentia Innovation manages SWiG as a joint industry project (JIP). The JIP is a collaboration of 28 members representing all parts of the supply chain, from major energy operators to subsea service providers and integrators to specialist instrumentation companies. It creates space for industry players to work together on technical matters related to subsea wireless technologies.
Shreekant Mehta, Senior Vice President, Energy Sector at Sagentia Innovation, says the SWiGacoustic specification is geared towards activities such as process control, monitoring, diagnostics and maintenance. By improving these areas, it has the potential to enhance the overall performance of subsea operations.
“Subsea vessel and vehicle operators use various wireless technologies, from radio frequency and acoustic to inductive power and data as well as free space optics and hybrid solutions.” Shreekant explains. “These technologies are complementary and perform different functions in different subsea environments and applications. However, without a common acoustic standard it’s difficult to achieve the interoperability needed for joined-up monitoring and control. SWiGacoustic solves this problem.”
SWiGacoustic is derived from the digital underwater signalling standard NATO ANEP-87 Edition A Version 1. It reflects decisions made by SWiG members to balance capabilities with compromise in key areas such as bandwidth versus range, frequency capability and transducer sizes.

Fugro Brings High-Efficiency Geotech Rig to
Us for Atlantic Shores Offshore Wind Fugro is back on the water for Atlantic Shores Offshore Wind (Atlantic Shores), performing a third year of integrated site characterisation services for the New Jersey-based offshore wind farm developer. Geophysical, metocean and environmental scopes of work are currently underway, while geotechnical services will commence later this month, using a newly commissioned Fugro C30 mobile rig.
Shores efficient, heave compensated drilling capabilities, as well as state- of-the-art downhole sampling, coring and in situ testing data. Fugro has also equipped the vessel with an automated launch and recovery system to use in conjunction with their Fugro SEACALF® DeepDrive system for performing seabed cone penetration tests. Together, these assets will ensure high rates of operability while also meeting Fugro standards for safety and sustainability.
Working from a third-party vessel, the Fugro C30 mobile rig will deliver Atlantic
Jeff Scott, Director of Marine Geotechnics for Fugro in the Americas stated: “We are thrilled to continue our integrated site characterisation work with Atlantic Shores this year,
and we are excited to deploy our new Fugro C30 rig on the project. We are confident it will deliver Atlantic Shores the timely, high-quality soils information needed to optimise foundation and cable design ahead of the target 2024 construction date.”
As with previous field season, all project Geo-data will be delivered in near real-time to Atlantic Shores via Fugro’s
Gaia.Hub web-based platform.
Gaia.Hub provides a single source of information for the entire Atlantic Shores project team and stakeholders, allowing users to access Geo-data any time, from any location, via a simple, intuitive website.
