The offshore shipowner said the facility is split into three tranches at lower rates.
The first is a conventional and Islamic term loan of $350m over seven years that will pay off existing debt.
There is also a revolving credit facility of $100m over five years, plus an unsecured term loan of another $100m.
These two will fund further capital expenditure.
“The new facility significantly lowers Topaz’s finance costs,” it said.
