Investor appetite for the recovering product tanker market saw $135m-worth of shares in two shipowners snapped up in just hours.

Greenbriar Equity Group sold a $45m chunk of New York-listed Ardmore Shipping on Tuesday.

Shortly after, Scorpio Tankers launched a follow-on offering that contributed $90m to its balance sheet at a time when it has $180m of debt maturing in 2018.
