side note:
being in my position, I get access to some sensitive info... and I can say with absolute certainty, that what I got is far from a "good" rate here... it's just unfortunate that I joined after the global oil price crash... three years ago, I could have had much higher rate - maybe more than double.
but nevermind, to each their own... everyone's fate had been written... and besides, I can't really I complain with this much. Imagine, I made 13000 gross working in KL before this. so it's a big jump already, for which I am thankful.

Nope, Sp***

That's quite high. Compared to me I was paid rm4,000 when i started as Jr engineer on chemical tanker in 2013.

In mid 2014, I went to offshore vessel (accomodation work boat) as 3rd engineer & was paid rm10,000. I went for chief & 2nd class program in 2016. In early 2018 I was promoted to 2nd engineer & was paid rm24,000.

In mid 2018 till today, I'm back to back on heavy lift & pipelay vessel as 3rd engineer receiving rm34,000 (obviously I don't mind to be at lower rank with the money I'm getting 😂).
