Shell Singapore has been for decades losing money. If not for a fact that the Singapore govt holds a big chunk of shares, the place would have imploded a long time ago.
An advise to someone young looking at joining. Look elsewhere. It would be disruptive if you were to be laid off right at the time you are building up your family. FYI, they have been retrenching large groups of people every decade or so and it looks like the frequency is getting shorter.
Shell SG has only a few good assets like Seraya and the ECC. The rest of the units are pulling these two down. Bad management is to blame for this degeneration of the plant and profit. Cronyism and nepotism is rife. Be on the good books of the big guy or the spawn of somebody and you will rise. You may imagine the scale of incompetence when oil theft/heist by the tanker loads have been going on for years.
Absolutely no other sane entity will be willing to buy over those assets. So eventually they will be demolished and Shell will try hard to retain the good units in the hope of making some profit but I doubt it will pan out that way. Eventually it would be turned into a tanks storage facility. If so, it would be an uphill task to make it profitable as management is clueless about motivating the workforce to be more productive. But also then it is a conundrum that Shell has designated Philippines as Asia's storage hub.
Shell could try bringing in older experience-proven expatriates and totally remove from site, the first 3 layers of the top mgmt to see if they can turn things around. Or fire them altogether for decades of failures.
