Developments in Control and Automation for Surface Demand Diving Systems Adriaen Winckers (Bluestream Offshore BV) and Johan de Bie (IHC Hytech BV) IMCA Annual Seminar, London, 19-20 November 2014 IMCA Annual Seminar– 19-20 November 2014 Overview of Presentation • Starting Point for Development • • • • • Conceptual Design System Engineering System Production Testing of Completed System Specific System Features • Using the System • Wrap-up IMCA Annual Seminar– 19-20 November 2014 Starting Point for Development IMCA Annual Seminar– 19-20 November 2014 Today’s dive controls for surface demand diving • • • • Last 2-3 decennia no significant changes in set-up Air diving control operated by hand Registration of dive by hand notes on dive log Most significant development: Dive Scan IMCA Annual Seminar– 19-20 November 2014 References • Developments in control rooms Saturation Diving systems • Medusa (Dutch Royal Navy) IMCA Annual Seminar– 19-20 November 2014 Design base for new surface demand diving system > Desire to improve dive(r) safety Dive Control: • Maximize support for Supervisors • Electronic monitoring and registration of complete dive including surface interval and decompression chamber • High redundancy, with possible fallback to conventional operation (fully manual) IMCA Annual Seminar– 19-20 November 2014 Design base for new surface demand diving system HP Compressor Container: • Compact HP compressor container incl. air buffers • Improved safety for breathing air compressors Decompression Chambers: • 1800mm decompression tanks with Stanag flange connection IMCA Annual Seminar– 19-20 November 2014 Conceptual Design IMCA Annual Seminar– 19-20 November 2014 Preparing initial concept design IMCA Annual Seminar– 19-20 November 2014 Discussing

Seminar– 19-20 November 2014 Air dive monitoring system IMCA Annual Seminar– 19-20 November 2014 Selectable BIBS gas selection IMCA Annual Seminar– 19-20 November 2014 Fully redundant dive control IMCA Annual Seminar– 19-20 November 2014 Fully redundant dive control IMCA Annual Seminar– 19-20 November 2014 Oxygen make-up and CO2 scrubber capability IMCA Annual Seminar– 19-20 November 2014 Fully connected modular surface supplied dive spread IMCA Annual Seminar– 19-20 November 2014 Using the System IMCA Annual Seminar– 19-20 November 2014 Extended Air Dive Monitoring System • Registration of dive team members • Planning of dives (in-water decompression / deck decompression) • Fully featured dive/decompression profile generator • Selection of dive as well as decompression profiles • Profiles on screen, easy to follow IMCA Annual Seminar– 19-20 November 2014 Extended Air Dive Monitoring System • Entire dive registered for each diver independently • Registration of dive and decompression separately: – – – – – Actual dive / decompression profile Changes in gas (Air > O2) Hot water temperature pO2, pCO2 Alarms • Registration and logging of dive and two separate DDC’s simultaneously IMCA Annual Seminar– 19-20 November 2014 Typical decompression table IMCA Annual Seminar– 19-20 November 2014 Profile editor IMCA Annual Seminar– 19-20 November 2014 Start point for

Transferring the divers to the DDC IMCA Annual Seminar– 19-20 November 2014 Monitoring the decompression IMCA Annual Seminar– 19-20 November 2014 Information on BIBS gas required IMCA Annual Seminar– 19-20 November 2014 From here onwards… • User Manual for Supervisors • Training program for Key personnel – Supervisors – Dive Technicians IMCA Annual Seminar– 19-20 November 2014 Wrap-up IMCA Annual Seminar– 19-20 November 2014 Summary of developments • Use of Extended Air Diving Monitoring Systems • Integration of more data from the DDC’s and HP Compressor in the Dive Control Panel with increased number of monitoring and alarm functions • Improved ergonomics of control panels for Supervisor and DDC Operators We believe these developments will have a positive effect on dive(r) safety
