In March 2011, one of the company's Panamax carriers, MS Oliva, was wrecked off Nightingale Island in the Tristan da Cunha group of islands, resulting in an oil spill which damaged local wildlife.

In May 2014, Dryships finalized the buying of a cape-size Bulk carrier. The company bought the ship, originally named Conches, which was built in 2011. The vessel was renamed Raiatea and officially changed hands on 24 April 2014 for a cost of approximately $53 million.

Following a series of reverse stock splits and the issuance of additional stock in 2016, in early 2017 the company refinanced its debt and announced an expansion into the gas carrier market with the purchase of a very large gas carrier.
