About marine fitter

The marine fitter reads engineering drawings and technical documentation and then transfers them to steel. Components are marked out, metal products cut with a torch or plasma, edges ground, and parts set in their assembly position and fitted to the parts of the hull already in place.

The fitter applies metal joining technologies: tacking components together, preparing them for a weld, controlling the gap and the bevel angle, and checking after welding that the structure has not distorted. Work runs through section pre-assembly in the shop and final assembly on the slipway or in a dock, where the sections are brought together.

The fitter follows vessel operational standards and uses marine technology, and applies pollution prevention rules when handling paints, oils and waste. Problems that arise during assembly are solved on the spot, with the work checked against the drawing as it goes.
