Hi

Table definitions, index definitions and execution plan please. Also the definition of all the functns used in there will help.

Is that distinct really necessary?

As Gail states.

You may get some mileage from this:
-- Extract this chunk of your query separately
--------------------------------------------------------------------
JOIN OSS_BENCHMARK_PRICE_REFERENCE PR
ON L.DAILY_BENCHMARK_LOCAL_SEQ=PR.DAILY_BENCHMARK_LOCAL_SEQ

JOIN RD_MARKET_PRICE MP
ON MP.MARKET_PRICE_SEQ=PR.MARKET_PRICE_SEQ
OR MP.MARKET_PRICE_SEQ=PR.FUEL_MARKET_PRICE_SEQ
OR MP.MARKET_PRICE_SEQ=PR.GAS_MARKET_PRICE_SEQ

LEFT JOIN OSS_MARKET_PRICE_DAILY FPD
ON MP.MARKET_PRICE_SEQ=FPD.MARKET_PRICE_SEQ
AND MP.PRICE_TYPE_CD ='FREIGHT'
AND FPD.OPTIMISATION_JOB_SEQ= @JOB_ID
AND CONVERT(VARCHAR(8), FPD.APPLICABLE_DT, 112)= CONVERT(VARCHAR(8), G.price_dt, 112)

LEFT JOIN OSS_MARKET_PRICE_DAILY FOPD
ON MP.MARKET_PRICE_SEQ=FOPD.MARKET_PRICE_SEQ
AND MP.PRICE_TYPE_CD ='FUEL OIL'
AND FOPD.OPTIMISATION_JOB_SEQ= @JOB_ID
AND CONVERT(VARCHAR(8), FOPD.APPLICABLE_DT, 112)= CONVERT(VARCHAR(8), G.price_dt, 112)

LEFT JOIN OSS_MARKET_PRICE_DAILY GOPD
ON MP.MARKET_PRICE_SEQ=GOPD.MARKET_PRICE_SEQ
AND MP.PRICE_TYPE_CD ='GAS OIL'
AND GOPD.OPTIMISATION_JOB_SEQ = @JOB_ID
AND CONVERT(VARCHAR(8), GOPD.APPLICABLE_DT, 112)= CONVERT(VARCHAR(8), G.price_dt, 112)
-------------------------------------------------------------------

-- something like this. Set it up either as a CTE, a derived table,
-- or (probably faster) a #temporary table
SELECT
PR.DAILY_BENCHMARK_LOCAL_SEQ,
APPLICABLE_DT = CONVERT(VARCHAR(8), FPD.APPLICABLE_DT, 112),

FREIGHT_RATE = CASE WHEN MP.PRICE_TYPE_CD ='FREIGHT' THEN FPD.QUOTE_VAL ELSE 0 END,
BUNKER_RATE = CASE WHEN MP.PRICE_TYPE_CD ='FUEL OIL' THEN FPD.QUOTE_VAL ELSE 0 END,
DIESEL_RATE = CASE WHEN MP.PRICE_TYPE_CD ='GAS OIL' THEN FPD.QUOTE_VAL ELSE 0 END

FROM OSS_BENCHMARK_PRICE_REFERENCE PR

INNER JOIN RD_MARKET_PRICE MP
ON MP.MARKET_PRICE_SEQ IN (PR.MARKET_PRICE_SEQ, PR.FUEL_MARKET_PRICE_SEQ, PR.GAS_MARKET_PRICE_SEQ)

LEFT JOIN OSS_MARKET_PRICE_DAILY FPD
ON MP.MARKET_PRICE_SEQ = FPD.MARKET_PRICE_SEQ
--AND MP.PRICE_TYPE_CD ='FREIGHT'
AND FPD.OPTIMISATION_JOB_SEQ = @JOB_ID
--AND CONVERT(VARCHAR(8), FPD.APPLICABLE_DT, 112)= CONVERT(VARCHAR(8), G.price_dt, 112)

GROUP BY
PR.DAILY_BENCHMARK_LOCAL_SEQ,
CONVERT(VARCHAR(8), FPD.APPLICABLE_DT, 112)


-- note that functions in JOINs and the WHERE clause are likely to render the search non-SARGable

select vout from OSS_MI_SPLITTING (@VESSEL_REF)

can also be shifted to CTE
