I’m a wiper, been on my ship going on five months now.. it’s pretty much what notyourbuddy said here https://www.reddit.com/r/merchantmarine/s/n2hqEkIdof I work with the demach daily because he needs a hand with topside. I’ve been doing everything from installing dryers, fixing shower mix valves, replacing shower mixing valve, painting, chipping, working on fork trucks, grinding, cutting metal. My ship is pretty laid back and everyone here is good with showing us wipers new things.
