Some vessel charterers are seeking to avoid crew changes before and during their voyages, according to Klaveness Combination Carriers chief executive Engebret Dahm, despite hundreds of thousands of seafarers stranded at sea.

With tight immigration restrictions across the globe during the coronavirus pandemic, changing crews on time has become much more costly, time-consuming in general and, on some occasions, impossible.

In a Marine Money virtual forum on Wednesday, Dahm said some charterers are even inserting new clauses in shipping contracts that could prevent seafarers from finishing their shifts.
