Bourbon has reached an agreement to amend the terms of a deal signed in 2013 and 2014 with ICBC Financial Leasing.
Under the pact Bourbon will see cash payments made to ICBC between 2016 and 2018 decrease by $240m.
In exchange there will be a two-year extension of the initial bareboat charters at a rate reduced by 8%.
ICBC will also benefit from “more favorable commercial terms”.
