LOTIS - Lidar fOr deTailed Inspection of underwater Structures
1 Feb 2024 to 30 Apr 2026
High resolution 3D maps are required for an increasing number of key subsea applications from installation and operation of offshore wind energy, asset decommissioning, environmental monitoring, and defence. Quantum photonic detection technologies can offer a step change in the resolution, accuracy, coverage, and speed of generation of these maps compared...
Underwater Single Photon Imaging System
1 Jul 2022 to 31 Mar 2025
High resolution 3D maps are required for an increasing number of key subsea applications from installation and operation of offshore wind energy, asset decommissioning, environmental monitoring, and defence. Quantum photonic detection technologies can offer a step change in the resolution, accuracy, coverage, and speed of generation of these maps compared...
Squads of Adaptive Robots (SoAR)
1 Oct 2021 to 30 Sep 2023
SoAR is focused on delivering a fundamental shift in the use of marine robotics through the networking of heterogeneous fleets of Autonomous Underwater Vehicles (AUV) and uncrewed surface vehicles overseen by a fleet level autonomy engine capable of adaptive mission planning. The existing paradigm of a single high-power vehicle with expensive support vess...
Subsea Enhanced Autonomous Mapping (SEAMless)
1 Oct 2021 to 30 Sep 2023
Subsea inspection and surveys require highly accurate mapping to support activities such as site assessment, detailed inspection, and asset maintenance. Data collected can be leveraged through the advancements and application of underwater robotics and autonomous systems to support future industry grow. By improving data accuracy and utility, operational ...
(HeRO) Hybrid-enabled Remote Operations
1 Sep 2021 to 31 Mar 2022
HydroSurv - an impact-driven innovator in Uncrewed Surface Vehicles (USVs) and marine geospatial cloud applications, is collaborating with Sonardyne International Ltd, Dynautics Ltd and Fischer Panda UK Ltd to develop an optimised hybridisation solution for remotely operated, uncrewed vessels. Combining innovations in human-assisted autonomous control of ...
HydroSurv - REAV-40 Offshore Wind Utility Extension
1 Apr 2021 to 31 Mar 2022
HydroSurv Unmanned Survey (UK) Ltd, (_HydroSurv_) is building upon the successes of its '_Robotics for a Safer World_' Demonstrator project by developing and showcasing a transformative environmental monitoring solution for the offshore renewable energy sector in collaboration with Sonardyne International Ltd - a world-leading underwater acoustic position...
Precise Positioning for Persistent AUVs
1 Dec 2017 to 29 Feb 2020
"This project will improve the navigational accuracy of autonomous underwater vehicles (AUVs) helping to further reduce the dependency on offshore infrastructure for wide area surveys of challenging marine environments. This will be achieved by a combination of three novel techniques: 1. Using enhanced autonomy to increase the accuracy of Long BaseLine (L...
AutoMINDER – Autonomous MarIne Navigation in Denied EnviRonments
1 Dec 2017 to 30 Nov 2018
Fault tolerant, high availability navigation systems used in the oil and gas industry today can already be considered automated. However, there are always at least two people on watch on typical mobile offshore drilling unit (MODU) as the Dynamic Positioning systems still rely on human intervention to take action when automatic fault detection and decisio...
Sound speed sensor accuracy and stability
1 Aug 2017 to 31 Mar 2018
An analysis of the performance of the transducer used in our sound speed sensor, particularly under conditions when deployed subsea and investigation into any physical changes that may occur.
Autonomous pipeline survey system
1 Feb 2017 to 31 Jan 2018
ASV, NOC and Sonardyne are working together to deliver an innovative and game changing offshore pipeline survey system. Utilising the benefits of autonomous vehicles on the surface and underwater to make a step change in operational cost and safety. ASV's autonomous surface vehicle C-Enduro will provide navigational updates and mission planning to NOC's A...
Autonomous Surface / Sub-surface Survey System
1 Jul 2015 to 30 Jun 2018
