Solstad Offshore keeps locking its vessels into long-term charters this month.

The Norwegian owner has re-activated two platform supply vessels (PSVs) that will work for ConocoPhillips Scandinavia.

The 5,300-dwt Normand Server (built 2011) and Normand Supporter (built 2012) have won new contracts for four years and eight months each.

Starting in April and May 2017, the contracts also carry three yearly options, Solstad said.
