French shipowner Bourbon has seen its first half loss grow in tough offshore markets.

The company said the net deficit was EUR 170.4m ($203.13m), from EUR 87.3m in 2016.

Revenue was down 8.7% at EUR 459.5m, while costs fell 10%.

The bottom line was hit by unrealised foreign exchange losses of EUR 50m, due to the weakening of the dollar.
