A perfect storm of chartering disputes, inflexible Covid rules and slow bureaucracy has left 18 seafarers stuck for months on an idle tanker in Singapore.

The episode concerns the 69,400-dwt Strofades (built 2006), one of several ships of Greece's troubled Eletson Corp that were arrested in March by CSIC Leasing, the leasing arm of China Shipbuilding Industry Corp.

Only three of the Strofades' 21 crew members have been repatriated since.
