From there they even mentioned BA didn't seemed to care less about the transformer outage and took the leeway to go ahead with the Q3 periodic maintenance instead. How ironic. And then best of all the chat room community question all the IB analysts where on earth did they derive the 6 months outage. Interesting to see how the Mr market responds to this news
Old man finally you said something positive. I fully agreed with you.
Why not you try your luck in Sapura Energy also? RO extended for another 9 months. Think about it.

sometimes in life, you need to take a considered bet. if it turns against you then ... so be it, but its a considered thing, better than buying lottery ticket.
Right from the start it was merely HV transformers failures or blown out and hence the production outage. Nothing tangible damage to assets class and compromised in asset safety and well being. Dream Big Tomorrow
A tranformer is used to step down electricity from 11 KV or higher KV to 415V.
Thro' motor control center a 3 phase 415V electricity current is feed into stator of the motor and the induced current will cause the rotor to rotate at 3000 or 1500 rpm.
The motor rotor is couple to the drive shaft of a pump and rotate the pump impeller inside the pump casing. The rotating impeller will sucked in the liquid from pump suction and exit the impeller at high velocity then upon exiting the pump casing discharge the velocity head is converted to pressure head. The pressure head will then force the liquid flow along the discharge piping to the intend destination.
Motor and pump are very common items use to transfer liquid from one place to another place along the piping. And normally important pump will have a hot stanby complete pump with motor and many pump spare parts and motor on cold stanby.
At the MCC trip amp will be set that will auto cut off the electricity supply if the amp is too high (above safe operating limit).
Running at perlong high amp will cause the motor stator wiring insulation melt and short circuit and burn the stator wiring.
High amp normally cause by pump impeller overload (too heavy due to sudden change in liquid viscosity or density or addition load (bolt and net) jammed at impeller
Recovering a transformer is not that difficult. If it is just short, replacing primary and secondary coil would settle. Identifying the root cause if there is an over current, might be more tricky. If over current is due to something mechanical, then the situation might be even more complicated. This might be why Armada do not want to specify the amount of downtime. 20% drop in market cap due to an incident is just too much.
Just to give you an idea, when I worked as a supervisor of a utility plant, an operator destroyed the transformer that was tied to transfer switch between normal power supply and emergency power. He did it by flipping switch on transfer station on and off a few times rapidly. Like a kid playing with a lightbulb. (The guy thought the power was not transferring quickly enough, so he re-engaged.) 'On and off' till it burned out. That is another way to destroy an equipment quickly. How things happen in reality.
The new transformer and switch set was 50 thousand dollars. That was 20 years ago. But still, estimate by the IB that cost of repair transformer on AK is 50 million is 1000 times to high.
There is no guarantee after the transformer is fixed other components both (mechanical and electrical) in the system would function normally. What if some of the sub-sea components like the pump won't function or cables open/short circuited or pipe leak etc?
However, I suspect the transformer failure is unlikely caused by over loading / over current situation - could be a case of the failure of the transformer dielectric oil / material due to maintenance oversight? In which case repair should be shorter than 6 months.
The shorts will have a field day and will not be only be a one day event. Better to allow the technical to stabilize before going in. Usually things are worst then is reported. Those who worked in the maintenance field will understand how reports are simplified to ease reporting. Need to figure out will Enquest demand for compensation if it will be 3-6 months of downtime. Will there be a settlement agreement of many more millions ? Risk vs reward.
How often do you get a "Black Swan" event that comes with Huge Discounts. Halo, it's not the irreversible and permanent assets damage beyond repair. The BA market cap is really really insanely low. Will keep adding into vault.
5.9 BILLION tickets in the market...even discounting the old man's holdings, it's still well over 3 billion. Easy to plunge not easy to rise with this kind of event, in this kinda half dead market.
Top 5 causes of transformer power quality problems
Loose connections — Long term vibration can loosen connections in electrical transformers. Going unchecked results in excessive buzzing and overheating.
Excessive harmonics — A higher temperature on a neutral termination may indicate the presence of harmonics. Per IEEE 519, the total harmonic distortion for voltage should be less than 5% for systems below 69 kV. The total demand distortion for current should also be less than 5% depending on the size of the source in relation to the load. Excessive harmonics on the third or fifth level often point to interference from electronic loads
Unbalance — When you compare temperatures of terminations and coils using a thermal imager, a higher temperature on one phase may indicate unbalance. When troubleshooting with a power quality analyzer, compare the current on each phase, noting that the maximum voltage on balance is generally 2%. That means the voltage on any one phase should not vary by more than 2% of the average of the three phases. The most common cause of unbalance is a change in load configuration, so quickly map out your overall equipment distribution system.
Overloading — If the temperatures are substantially higher than expected and the unit is not exposed to direct sunlight, then there’s most likely a problem with overloading and cooling. Compare kVA, voltage and current against the transformer’s nameplate. If the power consumption is greater than information listed on the nameplate, there’s likely an overload.
Cooling issues — Culprits are often cooling oil circuit blockages or failed cooling fans.
Good morning i3lurker, Can you provide me the link to CGS-CIMB report. I will write and urgent email to Amarda IR with CC to SC and Bursa to complaint is the CGS-CIMB accuracy of their information or misinformation?
CGS-CIMB Securities research estimates a similar downtime. It has included a loss of six months of BBC cash receipts, finance lease income and US$50 million (RM230 million) of repair and maintenance costs into the group’s profit and loss forecast
I added Armada this morning @ 48 sens . Thanks to those who contribute much insights on how the FPSO works and technical explanation of possible technical scenarios of the break downs. I am still convinced of the strong fundamentals of Armada and this incident is not going to sink the whole operations but part and parcel of oil and gas sector risks, one has to stomach it from time to time. Armada valuations is too low for its net operation cash flow for now at least,
I would like to draw your urgent attention to your bursa announcement and the CGS CIMB and Hong Leong Investment Bank (HLIB) arbitrary estimate of a six-month downtime. Please rebut or confirm the IB wild/irresponsible reporting.
Dear SC and Bursa,
Please investigate are CGS CIMB and Hong Leong Investment Bank (HLIB) arbitrary estimates of a six-month downtime bordering on wild/irresponsible reporting and violated SC rule and regulation on market manipulation?
Bumi Armada Berhad ("Bumi Armada") wishes to announce that, following a prolonged period of top quartile production and operational performance, production from the Armada Kraken FPSO ("Kraken FPSO") was recently shut-in following the failure of critical hydraulic submersible pump (HSP) transformers. The Kraken FPSO is owned by Bumi Armada’s wholly owned subsidiary, Armada Kraken Pte Ltd ("AKPL") and is deployed at the Kraken Field under a bareboat charter contract ("BBC").
AKPL, together with EnQuest (the field operator), planned and executed a restart of the facility but the attempted remediation programme was unsuccessful, and the Kraken FPSO remains shut-in.
AKPL is working with EnQuest to assess alternative technical solutions, with the aim to return to production, on a phased basis, in the coming weeks. In the meantime, key maintenance activities, originally scheduled for execution within two periods of single train operations in the third quarter of the year, are being executed during the period of shut-in. These activities are intended to negate the requirement for any further planned outages in 2023.
The current shut-in and future reduced level of production, means that BBC revenue earned by AKPL will be reduced. Given the current uncertainties, the financial impact of this incident cannot be reliably estimated at this point, but is expected to be material for Bumi Armada.
Further updates will be made from time to time when there are material developments.
CGS CIMB noted that FPSOs are typically required to achieve a minimum annual operational uptime of circa 95%, failing which the FPSO charterer does not pay the full bareboat charter contract (BBC).
“While FPSO Kraken received final acceptance from EnQuest in June 2017, Bumi Armada was paid just 70%-80% of the full BBC rate for failing to meet its uptime threshold until 1Q(20)20, when that threshold was achieved. For the past three years, the FPSO Kraken had been performing well, until the recent incident with the HSP (hydraulic submersible pump) transformer.”
Without guidance from either Bumi Armada or EnQuest, CGS CIMB has included a loss of six months of BBC cash receipts in 2H2023F, a loss of six months of finance lease income in the FY2023 profit and loss statement (P&L), and US$50 million of repair and maintenance costs borne solely by Bumi Armada and charged into its FY2023F P&L.
As such, the research firm lowered its FY2023 core net profit by 47%, implying the reduction in SOP valuation of Bumi Armada from 87 sen to 79 sen from the three adjustments above, and a lower TP of 69 sen.
Meanwhile, Hong Leong Investment Bank (HLIB) Research estimates that the Kraken FPSO has a daily charter rate of approximately USD480k/day (or USD175m/year), which accounts for some 35% of the group’s revenue contribution in FY2022.
“We are negative on this development. While we acknowledge that we do not have clarity of Kraken’s shut-in timeline yet, we decide to make an arbitrary estimate of a six-month downtime for the said FPSO,” it added.
That said, the research house trimmed its FY2023 net profit forecast by 38%, while leaving FY2024-FY2025 earnings estimates unchanged

If this news is True, I mean genuinely from a trusted source then it's one heck of a comeback for Armada and the investing community. Bravo
