In late 2023, the DSV Alvin program embarked on a detailed review of the program’s Emergency Response Plan (ERP), in an effort to ensure that Alvin operations are well prepared for emergencies. The presentation will include information on the ongoing ERP review and the resulting recommendations to date. Additionally, the presentation will share details on Alvin’s companion “Obseervation Vehicle”, including planned improvements and developing design of a new, and improved Alvin “OV”.
