SCIMPI

Simple Cabled Instrument for Measuring Parameters In Situ

CUTTING EDGE SUBSEA MONITORING

The SCIMPI concept affords trememdous operational cost savings during deployment. Because you can choose the number and spacing of modules in near-real time based on borehole logging, and no ROV is needed to deploy the system, you can drill, log, and emplace the observatory all during one visit to station.

 

Extremely frugal power management keeps the observatory actively collecting data for years between visits to its the ROV-replaceable seafloor battery pack.

 

Our SCIMPI-Compatible Subsea Observatory Modules incorporate fully re-designed electronics that improve on the functionality of the original SCIMPI prototype we developed for IODP-MI. 
 

Features: Versatile modularity, ultra long battery life, up to 128GB, internal data storage, cabled observatory connectivity, IODP drill, ship compatibility, and ROV serviceability.​ Standard modules measure pressure, emperature, and conductivity.

 

PARTNERSHIP

The system was jointly developed by the University of Rhode Island, Transcend Engineering, and Woods Hole Marine Systems, Inc., and funded by IODP Management, Inc.

Transcend Engineering was a key performer in the development of SCIMPI and is pleased to offer custom fabrication of fully SCIMPI-compatible Measurement Modules and Command Modules in 17-4 PH Stainless Steel and Grade 5 Titanium.

 

THE INVENTION

SCIMPI is an inexpensive seafloor borehole observatory for unconsolidated sediments. Emplaced via drill ship, the modular system provides flexibility in both the number of modules and the spacing between them. SCIMPI can last up to 4 years without replacing batteries, or can be connected to cabled observatory infrastructure. 

A SCIMPI prototype consisting of nine measurement modules was successfully deployed at ODP site U1416 in May 2013 during IODP Expedition 341S. Data were retrieved from the command module three months later and again in May of 2015, and presented at the AGU Fall meeting.

SCIMPI Deployment Videos 

SCIMPI is deployed into a borehole over 1600 meters down, through the

drill string of the JOIDES Resolution, May 2013.

SCIMPI Data Retrieval at ODP889

ROV dive at ODP889 to retrieve SCIMPI Command Module. The ROV arrives at the SCIMPI at around 4:15:00, disconnects around 5:10:00 and then picks up and ascends around 6:23:00.
