DryShips has revisited the loss side of the ledger, thanks primarily to millions of dollars in dry-docking costs for seven ships.

The George Economou-led diversified owner posted a $12.7m loss for the second quarter versus a $3.25m profit for the same period last year.

The bottom line was mostly impacted by a $26.1m spend on putting exhaust gas scrubbers and ballast water treatment systems on seven ships over 300 off-hire days.
