DUBAI- Galaxy Pipeline Assets, owned by a consortium of investors that took a stake in Abu Dhabi National Oil Company's (ADNOC) gas pipeline assets, has hired banks for a planned dual-tranche U.S. dollar-denominated bond sale, a document showed on Monday.

Galaxy hired Citi, HSBC and Mizuho as joint global coordinators, while First Abu Dhabi Bank, Santander, SMBC Nikko and Societe Generale join them as joint bookrunners, the document from one of the banks showed.

They will arrange a series of investor calls starting on Monday, which will be followed by a sale of fixed-rate dual-tranche bonds, subject to market conditions.

The amortising bonds will have maturities ranging from about 13 years to roughly 19-1/2 years.
