GEORGETOWN, Feb 18 (Reuters) - The fourth floating

production facility to be operated by a consortium led by Exxon

Mobil ( XOM ) in Guyana has departed from Singapore on its route

to the South American country's waters, according to a company

executive and LSEG vessel tracking data seen on Tuesday.

Once the floating production storage and offloading (FPSO)

vessel is installed, the consortium plans to boost output

capacity to 940,000 barrels per day (bpd) later this year. The

group produced an average of 616,000 bpd last year after

upgrades at two of its three facilities.

The fourth FPSO, One Guyana, was built by SBM Offshore

with a 250,000-bpd output capacity. Two more vessels

are expected to arrive in Guyana in the coming two years.

"I'm very pleased to announce (that it) just left Singapore

today on its way home to Guyana," said Hunter Farris, Exxon's

Vice President for Deepwater, at Guyana's Energy Conference in

Georgetown.

The floating facility began moving on Tuesday on its way

from Singapore through the Malacca Strait, vessel tracking data

showed.
