Oman has completed the first stage of prequalification on its $3.6bn Liwa Plastics Project petrochemicals complex in Sohar.

Contractors have been prequalified for one or more of the four engineering, procurement and construction (EPC) packages that are set to be tendered in the first quarter of 2015.

The first phase of prequalification focuses on individual companies, which have been split between ‘tier 1’ and ‘tier 2’ contractors for each package. The second phase will focus on the formation of consortiums led by ‘tier 1’ groups.

Omani newspaper Muscat Daily has released a list of prequalified companies:

The scheme is the biggest petrochemicals project in the sultanate’s history, and is expected to be completed by the end of 2018.

The front-end engineering and design (feed) study is being carried out by US-based engineering group CB&I, which is also the technology provider for the steam cracker, while Engineers India has been appointed as project management consultant (PMC).

The cracker will use a combination of feedstocks including natural gas liquids (NGL) extracted from natural gas, liquid petroleum gas (LPG) from the Sohar refinery and aromatics plant, dry gas from the Sohar refinery and condensates from Oman LNG.

The complex will have the capacity to produce 880,000 tonnes a year (t/y) of high density polyethylene (HDPE) and linear low density polyethylene (LLDPE); 300,000 t/y of polypropylene (PP); 90,000 t/y of methyl tert-butyl ether (MTBE); 41,000 t/y of butane; and 111,000 t/y of pyrolysis gasoline.
