Apply for visa by Swedish citizen

I am a Swedish citizen working on ships that call Malaysian ports very frequently. I do not have any work or resident permit in Malaysia as we go on international trade. I have been granted L-visa with multiple entries and 1 year validity at several occasions before but this has been done in Sweden. If my visa expires while onboard, do I have to go back to Sweden after sign off to get a new visa or can I apply through visa service in Malaysia. I am married to Chinese citizen and hold original marriage book with me. If I can apply in Malaysia, what kind of visa would most likely be granted?
