Only the "toughest" investors are stepping into the refinancing fray for offshore support vessels, according to Braemar Naves.

The finance arm of UK shipbroking group Braemar Shipping Services has been heavily involved in restructurings in a hard-hit sector before and during the coronavirus pandemic.

Braemar Naves managing partner Axel Siepmann said the market has been impacted twice as badly as other types of shipping, due to Covid-19 disruption and oil price falls.
