Can this sort of issues be prevented by testing in factory and on the construction yard before startup at final location ?

Oil major ExxonMobil has revealed its disappointment with the performance of the Liza Destiny FPSO, operating on the Liza field off Guyana, following technical issues, which forced it to reduce output to a minimum.
Offshore Energy has reported on this issue several times since the problems started in January 2021.
The technical issue was related to a seal on the gas compressor on the SBM Offshore-owned FPSO Liza Destiny, prompting ExxonMobil to temporarily increase the flare above pilot levels to maintain safe operations.
ExxonMobil, SBM Offshore, and MAN Energy Solutions have been working to fix the problem since then.
By the end of March, teams of experts were making final preparations for the start-up of the flash gas compressor on the Liza Destiny FPSO, in order to restore the flare to background levels.
But the repairs were still not completed by early April. Instead, the team onboard the FPSO initiated a comprehensive three-phase testing programme.
ExxonMobil said that the final stage of testing would take place this week after the removal of temporary instrumentation.
