A total of 186 services to vessels carrying 2.6 million tonnes of potentially polluting cargo and fuel were carried out in 2022 clearly showing the critical role of professional salvors in protecting the marine environment.

The shipping and insurance industries recogniSe their responsibilities and the importance of maintaining their "licence to operate" and the availability of emergency response services is a critical part of meeting those responsibilities.
The ESG (Environment, Social and Governance) agenda is important and it is vital that the capability,
and willingness, of commercial salvors to provide services around the world is valued.
The number of services fell in 2022 but, overall, the amount of pollutants has stayed consistent. The
number of containers is lower than last year but, after bulk cargo, still represents the most significant
category with our members providing services to vessels carrying 50,000 TEU amounting to some
747,270 tonnes of cargo. It compares with 141,000 tonnes of crude oil, confirming the shift over the
past decades as oil trades have become safer.
Boxes stuffed with harmful and dangerous goods including plastic pellets (nurdles) represent one
of the biggest threats to the marine environment.
They are potentially very damaging and, with the added issue of misdeclaration of contents,
dangerous to deal with.
Cargoes of refined oil products in 2022's numbers were similar to crude oil at 144,808 tonnes.
Chemical cargoes rose to 79,319 tonnes in 2022.
Bulk cargoes increased significantly to 1,235,741 tonnes in 2022 compared to 424,719 last time. This
category includes products such as coal, scrap steel, grains, soya and cement. A number of bulk
cargoes are not included as potential pollutants and ISU members also provided services to
bulkers carrying 113,926 tonnes of non-hazardous dry bulk – mainly metal ores.
11 cases had more than 2000 tonnes of bunkers on board and the total of bunkers involved was
108,112 tonnes. A number of the services noted in the survey did not record the quantity of bunkers
or the cargo-type meaning the reported totals likely represent a more modest total than the reality.
ISU is transparent about the fact that not all these potential pollutants were at immediate risk of going
into the sea. Some cases will have had limited danger, but others will have carried a real risk of
causing substantial environmental damage.
The 186 services in 2022 included 12 wreck removal/marine services contracts; 16 Lloyd's
Open Forms; 38 towage contracts; 4 Japanese Forms; 4 Lump Sum; 5 Day Rate contracts; 84
other contracts (including commercial terms and common law salvage) and 23 Turkish Forms.
The survey was first conducted by ISU in 1994 and the methodology was updated in 2014 to include
a wider range of potential pollutants including containers and hazardous and dirty bulk cargoes.
In the period 1994 to end-2022, ISU members have provided services to casualty vessels carrying
41,478,058 tonnes of potential pollutants, an average of 1.4 million tonnes per year.
