South Korea-based Samsung E&A is executing a project to repair units at Kuwait’s Mina Abdulla (MAB) refinery that were damaged by Iranian attacks on the facility, according to industry sources.

The facility has been hit several times by Iranian attacks since the US and Israel attacked Iran on 28 February, starting a regional war.

Samsung E&A is treating the repair work as confidential, and only those who are directly working on the project are being told about the nature of the damage and which units are being repaired, sources said.

Samsung E&A has an existing relationship with state-owned Kuwait National Petroleum Company (KNPC), which operates the facility.

The South Korean company declined to comment on the MAB repair project when contacted by MEED.

Kuwait Petroleum Corporation (KPC), which is the parent company of KNPC, did not respond to a request to comment from MEED.

Samsung E&A originally executed a key part of KNPC’s $16bn Clean Fuels Project (CFP), which came online in 2021.

The CFP project integrated the MAB refinery with the Mina Al-Ahmadi (MAA) refinery, as well as upgrading several existing units and developing several new units.

Samsung E&A won the contract for package one of the CFP in consortium with UK-based Petrofac and the US company Chicago Bridge & Iron.

This package was worth $3.7bn and the scope of work included:

• Construction of crude distillation unit with a capacity of 264,000 barrels per stream day (BPSD)
• Construction of atmospheric residue desulphurisation (ARDS) units with a capacity of 50,000 BPSD and 100,000 BPSD

Facilities in Kuwait have been hit by Iranian missiles and drone attacks multiple times since the regional conflict began. State-controlled media has not published details on which sites Iran has hit.

Even so, it is clear that some of the most frequently hit facilities include the MAA and MAB refineries.

On the morning of 20 March 2026, following a drone attack, fires broke out across multiple units at the Mina Al-Ahmadi refinery. In April, the same refinery came under attack three times within a two-week period. These attacks also started fires in a number of operational units, forcing them to shut down.
