* Monthly sales dip for all conventional grades
* Bio-blended LSFO sales extend climb to fresh high
* LNG sales retreat, snapping uptrend from Jan 2023

       SINGAPORE, Sept 14 (Reuters) - Singapore's marine fuel
sales, also known as bunker sales, retreated in August as vessel
calls and container throughput fell from July, official data
showed on Thursday.
    Sales in August totalled 4.26 million metric tons, down 5.8%
month-on-month but up 3.4% year-on-year, data from the Maritime
and Port Authority (MPA) showed.
    The decline came amid lower vessel calls for bunkering,
which totalled 3,483 in August, dipping 0.8% from July.
        Bunker sales at Singapore are a key indicator of
sentiment at the world's largest ship refuelling hub, which is
also one of the busiest shipping lanes globally.
  
    Singapore's container throughput eased to 3,328,400
twenty-foot equivalent units in August, after hitting a
year-to-date high in July.
    Low-sulphur fuel oil (LSFO) sales for bunkering totalled
2.51 million tons in August, down 5.8% from July.
    Meanwhile, high-sulphur marine fuel oil (MFO) sales totalled
1.39 million tons in August, down 6.1% from July.

    ALTERNATIVE FUELS
    Sales of bio-blended LSFO extended gains to a new monthly
record high of 52,600 tons in August, reflecting a steady,
though still gradual climb in volumes this year.
    Total bio-blended LSFO sales were at 281,500 tons in 2023 so
far, the data showed.
    Meanwhile, bunker sales of liquefied natural gas fell at
15,600 tons in August, snapping an uptrend since January 2023.
Total LNG bunker sales totalled 70,670 tons to date this year.
