The salvage industry is having to cope with significantly lower levels of income, according to the latest figures from the International Salvage Union (ISU).

According to the ISU, its membership — which includes all the major salvage companies — earned $482m in 2019.

While the figure is up on the $409m in 2018, salvage income has remained well under $500m for the past four years and is still a long way off the $717m earned in 2015.
