DryShips expects to incur up to $100m in costs through 2020 on "future proofing" its fleet with exhaust gas scrubbers and ballast water systems.

The New York-listed owner foresees that level of spending toward as many as 1,300 off-hire days across its 19-bulker fleet as a result of their installation, begun this year.

"During 2019, the company has scheduled and started implementing an overall 'future proofing plan" for its fleet update," the company said in its first-quarter earnings report.
