Cabled Observatory Mechanical Presentation

School of Ocean and Earth Science and TechnologyFebruary 2006

Aloha Phase 1 Mechanical Systems

Main Assemblies:Float Package

Proof Module

Cable Termination Frame

Bottom Line:-Mechanicals have gone smoothly-Manufacturing and testing complete-Final assembly remains-Quick tour or three main assemblies

Buoyancy Test

•Float allows for the retrieval of the proof module .•Link between termination frameand proof module will be cut byROV.
