Oslo-listed Siem Offshore has posted a bigger loss for the first quarter despite stronger revenue.
The company said the deficit was $17.3m to 31 March, against $9.6m in the same period a year ago.
Revenue climbed to $107.4m against $70.8m, but last year's bottom line was boosted by a $10m gain in currency movements.
The contract backlog stood at $1.14bn
