Supplies were also expected to be disrupted in the Netherlands, where labour strikes started on Monday at Shell's 404,000 bpd Pernis oil refinery. India's Hindustan Petroleum Corp, meanwhile was issuing gasoline purchase tenders, though it was unclear whether the refiner had bought any of the cargoes it was previously seeking through various term and spot tenders. Japan's JXTG Nippon Oil & Energy has restarted the 115,000 bpd crude distillation unit (CDU) at its Osaka International Refining Co after shutting it on March 4 for a scheduled maintenance.
