Bureau Veritas (BV) has delivered an Approval in Principle (AiP) to iXblue for its unmanned surface vessel (USV) named DriX.

DriX is an 8 metre long Unmanned Surface Vehicle (USV) equipped with advanced perception means, including a radar, a lidar and cameras, as well as artificial intelligence, which enable it to adapt to its environment, avoid obstacles and carry out missions autonomously. Designed to support hydrographic and geophysical surveys, water column analysis and subsea positioning operations, DriX has been used by major hydrographic institutes and energy companies worldwide.

The AiP addresses the safety requirements of the marine drone, which operates under the concept of remotely supervised autonomy.

Developed by French company iXblue, DriX has been certified by BV for its system architecture, its operational envelope, its construction (Malta Cross certificate for the hull), as well as its autonomy functions. The NI641 “Guidelines for Autonomous shipping” have provided a framework for a thorough analysis of the DriX architecture and its critical functions in a way that is adapted to autonomous marine systems.

In order to support the Approval in Principle, Bureau Veritas Solutions Marine & Offshore (BV Solutions M&O), the technical advisory component of Bureau Veritas Group, conducted a Hazard Identification (HAZID) study, as required by BV NI641. This HAZID study identified and assessed the hasards of Maritime Autonomous Surface Ships (MASS) when unmanned, taking into account the level of automation, direct and remote control, autonomy, area of operation and vessel type and design. BV Solutions M&O also conducted a Failure Mode Effects and Criticality Analysis (FMECA) on critical components previously identified during the HAZID study in order to identify, evaluate and mitigate the effects of essential equipment failure and to improve the reliability of automation systems associated with essential services.

This first certification of an Unmanned Surface Vessel (USV) by BV will help strengthen global acceptance of this technology by supporting operators in their risk analysis and mission planning for USVs deployment. This comes as the USV sector is expanding rapidly, and the acceptance of these novel marine drones depend on the capacity to demonstrate that they are safe to deploy and operate. BV and iXblue have been working in close collaboration to raise the standards and acceptance of USVs.

Stéphane Vannuffelen, marine autonomy technical director at iXblue, said: “We are convinced that the acceptance of autonomous solutions in the marine ecosystem requires a collaborative approach between manufacturers, class societies and authorities, and this work done with BV goes in that direction. This certification is a major achievement not only for DriX, but for the whole maritime industry, supporting its 4.0 transition.”

Laurent Leblanc, senior vice president of technical & operations at Bureau Veritas Marine & Offshore, commented: “Smart vessel operations can enable the maritime industry to increase productivity, predictability, and efficiency while reducing operational risk on the water. At BV, we are committed to support innovation with our robust set of standards to enable these new technologies to reach the market and ensure that they are safely implemented.”
