Due to the ongoing civil war between Ansar Allah (the Houthis) and the Saudi-backed, internationally recognised government of Yemen, the tanker FSO Safer sat rusting and unmaintained off the coast of Yemen in 2022.

Although the catastrophe was preventable from a technical perspective, political barriers had restricted progress for years. In this multi-issue, multi-party negotiation participants are tasked with finding a way to avoid disaster.
