Leveling an Underwater Habitat Anchored
at Four Random Locations
The habitat consisted of an 8' diameter ring/platform which had an 8' dia by 8' high "baggie" over it. The baggie was restrained by net, cables and a top ring. The habitat had 12 tons of buoyancy and the most economical anchors were rocks in situ. The rocks were not arranged in a neat four point array. Given four randomly arranged anchoring points, how do you determine appropriate lengths for the four anchor chains to moor the habitat in a level attitude?
The cross beams and ropes attaching the floatation means are symmetrical.
Ropes A and B slide through eyebolts on their respective Beams.
Rope A is tightened and Beam A is slid along it to a level condition.
Rope B is then tightened appropriately and Beam B slid along it to a level condition.
The anchor line portions of Ropes A and B are measured.
Those measurements are reproduced in chains and turnbuckles to anchor the habitat.
