Background
The present case concerned a collision in the Suez Canal in July
2018 between three vessels, PANAMAX ALEXANDER, SAKIZAYA KALON and
OSIOS DAVID, the first of which had been on route to Iran. At the
time of the collision, President Trump had announced the
re-introduction of sanctions against Iran.
In English law, and in many other jurisdictions, the arrest of a
vessel is a means of establishing jurisdiction and of obtaining
security in maritime claims. Arrest is costly, however, and may not
be the ideal way to do either. As a result, the owners of ships
involved in a collision often enter into a jurisdiction agreement
and exchange letters of undertaking from each owner's P&I
Club (or Hull Underwriters) by way of security
("LOUs").
