The iron cylinder

Wheel Wreck: Intro | Cargo mound | Iron cylinder | 3D site plan | Dive video

A small group of iron fragments was observed some 11m to the north-west of the cargo mound. These fragments all appear to be the remains of a cast iron cylinder which has been broken into six major pieces and a greater number of smaller fragments. The seabed in this area is composed of large stone boulders, so locating all the smaller fragments was problematic.

Below is a site plan, a reconstruction drawing, and an interactive 3D model of the cylinder fragments.

Reconstruction drawing

A greyscale reconstruction drawing of how the cylinder may have appeared. The image is divided into two columns. The left column shows the side view of the cylinder standing upright as it may have appeared. The right column is split horizontally. On the top is a view of the cylinder from the top, essentially circular but with a rectangular protrusion. The lower half of this column shows the plan view from underneath - a circular shape with regular holes showing where rivets would have been positioned.
