How it works
Demurrage is liquidated damages paid by the charterer to the owner when cargo operations run beyond the allowed laytime. It is set as a daily rate in the charter party and runs continuously once laytime is exhausted; the principle "once on demurrage, always on demurrage" means many laytime exceptions stop applying.
Demurrage is one of the most common sources of post-fixture dispute, hinging on whether laytime was correctly counted and whether delays fall on owner or charterer.
