New Delhi: Hindustan Petroleum Corp Ltd has again delayed a 35-day shutdown of its Mumbai refinery to integrate new units as key equipment is yet to arrive, and now plans to begin work in April-May, company sources said Tuesday.

Mumbai mess: BHPV’s failure to deliver key equipment on time delays HPCL’s move to integrate new units at its Mumbai refinery

The new units are needed to enable the firm to meet tougher rules on clean fuels, which will come into force nationwide from 1 April, 2010, and were originally due for completion last year.

HPCL then planned to shut the 110,000 barrels per day refinery in October-November, but deferred it for three months as supplier Bharat Heavy Plates and Vessels (BHPV) failed to deliver heaters and furnaces in time.

Now the firm has again had to reschedule its plans for the same reason.

“BHPV have given us a revised time frame based on which we plan to take 35-day complete shutdown of the refinery in April-May. But this is also subject to BHPV delivering the new heaters and boilers by March," a senior company official, who did not want to be named, told Reuters.

Officials at the Mumbai refinery confirmed the revision.

The refiner also aims to raise the capacity of the Mumbai unit to 158,000 bpd by end-2008, said the senior official.

HPCL hopes to complete a similar green fuel programme and raise capacity at its 150,000 bpd Vizag refinery in southern India by 16,600 bpd by September 2008 without shutting it fully.
