Norwegian OSV giant Solstad Offshore's bondholders have backed its debt suspension plans in a crucial vote on Wednesday.

The investors agreed to defer interest payments falling due under the NOK 1bn ($117m) five-year bond expiring in 2019.

This agreement applies from 20 December and was a condition of a similar deal with its lenders.

But the bondholder assent is in turn conditional on a principal and interest suspension being agreed with the financial creditors of certain Solstad subsidiaries.
