Presentation Transcript

  1. “Changing Industry Demands Redesign the OSV’s” This paper was first presented at the “ 4th International Conference on Technology and Operation of Offshore Support Vessels OSV Singapore 2011 organised by The Joint Branch of the Royal Institution of Naval Architects and The Institute of Marine Engineering, Science & Technology (Singapore), The Centre for Offshore Research & Engineering, National University of Singapore, and Newcastle University Marine International, Singapore.

  2. INTRODUCTION

  3. NEW RULES AND REGULATIONS • OSV’s carry Noxious Liquids, chemicals, Drill cuttings • > 100 personnel on board, SPS Code • Dynamic Position Keeping • Probabilistic Damage Stability • Crew Comfort • Environmental features • High Capex costs – more than a VLCC

  4. ANCHOR HANDLING Existing AH Tugs 150T – 200T BP. Deeper Waters, Larger Rigs Require BP > 300 Ton Winches > 600 Ton Brake Capacity > 25000 BHP Robotic AH Cranes ARF to land large anchors on deck

  12. SPS CODE • Subsea Construction and Maintenance • Diving Support • Pipe Laying • Seismic • Research and Training • Well Intervention • 200 personnel • Need higher standard of Safety

  13. CREW COMFORT

  14. DYNAMIC POSITIONING

  15. FUEL CONSUMPTION Charterers look for fuel efficiency Innovative Hull and Propulsion Designs X-Bow Hybrid combination of Diesel Mechanical and PTI Depends on operational profile Long voyages of supply vessel favor Hybrid

  16. FUEL CONSUMPTION AH needs high BP - Diesel mechanical straight shaft Diesel Hybrid Supply vessels need less power but economic steaming Diesel mechanical and Hybrid have nearly similar consumption Low Load Longer steaming between platforms Favor Hybrid savings 500T per year
