The 2021 capsize of the liftboat Seacor Power, with loss of 13 lives, has focused attention on the afloat stability of liftboats in transit. This paper presents a numerical method of simulating the dynamic capsize of liftboats in waves using time domain analysis and a commonly used computer program. Capsize of a similar vessel to the Seacor Power is predicted in 6-ft quartering and beam seas even without wind. Model tests are proposed to help calibrate calculation techniques and define limiting metocean conditions more reliably for safe transit of liftboats.
