DUBAI, July 16 (Reuters) - BlackRock ( BLK )-led

investors in Saudi Aramco's gas pipelines network have

hired banks to arrange investor meetings ahead of a potential

sale of bonds, a bank document showed on Tuesday, to refinance a

loan that backed their stake purchase.

The investors had in 2021 taken a 49% stake in Aramco Gas

Pipelines Co in a $15.5 billion lease-and-leaseback agreement.

They are now issuing amortising bonds to continue

refinancing the $13.4 billion bridge loan that backed the deal.

Greensaif Pipelines Bidco, the debt issuer indirectly owned

by BlackRock ( BLK ) and Hassana Investment Co, hired JPMorgan ( JPM ) and

Standard Chartered ( SCBFF ) to arrange fixed income investor meetings

starting on Tuesday.

A sale of 12- and 18-year U.S. dollar-denominated amortising

bonds will follow, subject to market conditions, the document

from one of the banks arranging the sale showed. The tranches

have weighted average lives of 10 and 14.5 years, respectively.

In February last year, Greensaif raised $4.5 billion by

selling amortising bonds.

BlackRock ( BLK ) and its affiliates own 77.2% of Greensaif, while

the rest is owned by Hassana, the investment arm of Saudi

Arabia's General Organization of Social Insurance.

A similar lease-and-leaseback deal in 2021 saw Aramco agree

to sell a 49% stake in its oil pipelines network to a consortium

led by U.S.-based EIG Global Energy Partners for $12.4 billion.
