I am a intern at shipyard.

I started my internship at a shipyard two days ago. Unfortunately, I was late in choosing a good place to do my internship. So, the shipyard where I am currently doing my internship is not suitable enough for me to learn useful things related to engineering. There is just an old ship, built around 1980, on the slipway. I want to make the most of it, but I do not know what to do. Give me some advice.

A stability curve can look fine while its area is wrong by 57.3x

I was wiring a browser-side coursework checker and realized this one is easy to miss: Simpson's rule will integrate whatever step you give it.

If the heel step is 10 degrees and you use h = 10 instead of h = 0.1745 rad, every area comes out 57.3 times too large. The GZ curve still looks normal, so the mistake may only show up in the criteria table.

I put the hand-calculation chain and a small cross-checker on the MetaCAD site I'm building: ship stability coursework workflow.

It's for coursework and preliminary checks, not vessel operations. The page shows the substitutions instead of just returning pass/fail.

What other stability-assignment errors have you seen survive a quick visual check?

Naval architect from Pakistan

i am an undergrad Naval Architecture student at Pakistan Navy Engineering College (PNEC) in Pakistan. Since there is only one major shipyard in Pakistan, local job opportunities are limited and often offer lower compensation. Are there international job opportunities available for graduates who maintain a strong GPA and have extra technical skills, and how can I apply for them
