Lining up the Wreck...

Today's work was largely devoted to making the detailed measurements, in three dimensions, that will allow a model of the wreck to be created on computer. This can then be used to output drawings and diagrams highlighting construction features or providing an overview of the vessel. To augment the datum points established yesterday, each of the upright frames (ribs to the layman) on the Starboard side of the wreck was identified and labelled. Port side remains will be similarly labelled tomorrow. The labeling of the frames considerably helped the teams working to record the various measurements. The line drawing shown was drawn up from a photo mosaic generated on day one.

Checking out the Henry..

A visit was made to the basin of the dry dock at the Marine Museum at the request of staff concerned about the situation of the Alexander Henry. The aim, fully achieved, was to establish the clearances between ship and dock and to identify any hazards to the ship's hull within the basin.

In a dive lasting 30 minutes, it was demonstrated that the ship has at least two feet of clearance at all points, the low point being the stern, something which is quite obvious from the surface. A number of large concrete and steel objects were identified in the dock, all on the Port side of the ship.

The picture, which I thought quite striking in the sunlight, is a reflection in a car window.
