Exports of ultra-low sulphur diesel (ULSD) from the Russian Baltic Sea port of Primorsk are expected to fall to 947,000 tonnes in May from 990,000 tonnes in April amid an infrastructure crunch, traders said on Monday.

The figures mean daily shipments in May would fall by 7.4 percent, compared with April. Russian oil pipeline monopoly Transneft plans to ship diesel via a pipe initially designed for crude oil to Primorsk in the autumn to expand the capacity of the route.’

Traders have said Primorsk will export 10.16 million tonnes of ULSD this year, up 26 percent from 2013, as Russian refineries undergo modernisation to produce higher-grade fuels.
