The Mobile Undersea System Test Laboratory (MUST) Unmanned Underwater Vehicle (UUV) operated by MSubs Ltd, Plymouth is used by the Royal Navy (RN) Maritime Warfare Centre (MWC) for Tactical Development (TacDev) trials in support of Anti-Submarine Warfare capability development.
BMT was tasked to conduct a Hazard Identification and Risk Assessment of a trial aimed at achieving the requirements of an RN submarine’s certification while contributing to the TacDev of a torpedo capability.
The aim of the Risk Assessment was to justify claims that risks arising from the conduct of the trial involving the MUST, an RN submarine, torpedoes and numerous surface and underwater assets within the confines of a shared exercise area were As Low As Reasonably Practicable (ALARP) and either Broadly Acceptable or Tolerable and that environmental impacts were ALARP.
The safety and environmental argument for the trial was presented as a Claims Argument Evidence (CAE) diagram, an established graphical method which provides a clear picture of the argument supporting the Safety and Environmental Case for the trial.
A Hazard Identification and Assessment Meeting was conducted by a team of Suitably Qualified and Experienced Personnel (SQEP) to identify, evaluate and record all potential risks to personnel, platforms, equipment and the environment associated with the trial.
The identification of hazards was conducted using the Structured What If Technique (SWIFT), a structured brainstorming technique used by a multi-disciplinary team. Environmental risks were identified utilising the SWIFT technique and a conceptual input/output/outcome model.
A systematic Risk Assessment was undertaken which demonstrated that risks associated with the trial were ALARP and either Broadly Acceptable or Tolerable subject to the completion of actions identified during the Safety Assessment process. Actions included the development of effective geographic and depth separation of the various assets used in the conduct of the trial, reducing the potential for collision resulting in injury to personnel and damage to assets, equipment and the environment.
The Environmental Impact for the trial was considered to be Environmentally ALARP (E-ALARP). Environmental Risks are considered acceptable and to be E-ALARP subject to the implementation of identified Hazard Management Actions (HMAs).
