Keystone Shipping is taking three Great Lakes bulkers out of service as it tries to cope with the pandemic-related slump.
The US manager of the fleet of shipowner USS Great Lakes Fleet is also laying off 94 workers, including crew members.
The 75,000-dwt Edgar B Speer (built 1980), the 47,000-dwt Roger Blough (built 1982) and the 27,100-dwt Philip R Clarke (built 1952) are the ships being stacked.
