Nordic American Offshore (NAO) has reported a second quarter profit of $4.1m, up from $1.7m in the first quarter.

The company's fleet of six operating vessels, entirely deployed in the North Sea UK sector, were fully utilised in the quarter and pulled in $14.6m of net charter revenue.

The results follow the company's successful listing on the New York Stock Exchange in June, with an IPO that raised proceeds of around $100m

NAO has four PSVs on order, a pair each at Vard Aukra in Norway and Ulstein Verft, with deliveries set for 2015.

The company sees a healthy demand for PSVs, including potential for some of its suitable vessels to be deployed in the growing Arctic region.
