"Our outlook for the shipping and shipbuilding market in 2013 has improved." wrote wrote president and ceo Björn Rosengren in the earnings release. "The lively ordering of product tankers, large containerships and gas carriers is expected to continue during the rest of the year. Furthermore, the offshore sector is expected to remain active, although with a different contracting mix that favours mobile drilling units and FPSOs more.
"Current emission regulations and the focus on fuel efficiency create interesting opportunities in gas fuelled vessels and environmental solutions. Financing is expected to remain difficult, but some signs of easing can be seen across the industry. Overall, the contracting mix is expected to be more balanced than in 2012, with activity in all major vessel segments.
