I always thought “Golden Shadow” was just a support and play toy holder for “Golden Odyssey”. It seems to be used for a lot of ocean research work as shown in this site. This is the brainchild of the Golden Fleet owner; His Royal Highness Prince Khaled bin Sultan bin Abdulaziz.

In the top link headers of this page there are also some Video Clips, 21 in total, while most of them are amazing footage of sea life a few show some of the engineering and day to day operations of the yacht.
