We used this SSP (Semi Submerged Platform) ship, Kaimalino, to deploy a
Short Prototype String (SPS) in '87. This SPS consists of 7 optical
modules, 2 calibration light sources, and a main electronics package. The
purpose of the SPS was to demonstrate the feasibility of the water Cerenkov
detector in the deep ocean. Cosmic ray muon's depth-intensity relation had
been successfully measured down to 4000 m in the ocean.
This eventually led to full approval of the DUMAND project in '89.
