Siem Shipping continues to explore further diversification after adding car carriers to its core reefer fleet this year.

Oslo-listed Siem booked two 7,000-ceu car and truck carriers in Croatia earlier this year and has 28 reefer vessels to its name.

In reporting a third quarter profit today the owner said it is continuing to evaluate opportunities in other sectors of the shipping market.

Siem, which trades as Star Reefers, recorded a gain of $2.5m in the three months to the end of September, overturning red ink of $200,000 at the same stage in 2014.
