Norway's Boa Offshore has spotted some green shoots of recovery in the stricken North Sea oil and gas sector.

The financially restructured owner of construction ships, anchor-handling tug supply units, dredging barges and tugs said its short to medium outlook had worsened dramatically over the first six months of 2020 due to the Covid-19 pandemic and oil price falls.

The disruption caused a drop in demand for oil of at least 20%, compared to the first half of 2019.
