Appendix A of the Ghosts of Saltmarsh adventure, "Of Ships and the Sea", describes a number of common hazards during sea travel, one of which is fire (p. 201). Fire is presented as a hazard that requires a group check to get out of the situation. Each check requires 5 minutes of work.

By the hazard rules, it seems like it would just put all officers (PCs) out of combat for the duration.
