This paper focuses on the legal framework applicable to potential technological disasters during an armed conflict. In particular, it focuses on the case study of the safer oil tanker in Yemen. The safer is a Floating Storage and Offloading oil tanker anchored approximately 60 kilometers from the west coast of Yemen. The oil tanker is legally owned by the national oil company, the Safer Exploration & Production Operation Company (SEPOC). Currently, the Houthis control the waters where the safer is anchored.1 Before the armed conflict in 2014, this tanker was used to store and export oil from the fields by SEPOC. Since then, the oil tanker has been almost abandoned by the company. While during its functioning, the vessel counted almost one hundred people of the crew, there are only a few employees of SEPOC who are monitored by surveillance cameras installed by the Houthis. The control exercised by the Houthis has diminished the capacity of the crew to work independently. Since September 2020, SEPOC declared that the company does not exercise anymore an effective control over the tanker
