1 Workshop: Examining the Science & Technology Enterprise in Naval Engineering January NAS, Washington DC Owen H. Oakley, Jr. Chevron E.T.C.

2 Introduction Owen H. Oakley, Jr. University: BS (NA&ME) UofM 66 MS, Engineer s, PhD (Ocean. Eng.) MIT 72 PostDoc (NA&ME) UC Berkeley, Asst. Prof. MIT (Ocean. Eng.) Gulf Oil: offshore R&D ( 77-85) Chevron ( 85-Pres): D&C: Anoa Proj., Indonesia; Hibernia Proj., Canada & Korea R&D: deepwater development, risers, CFD OMAE Conference: CFD & VIV Symposium MIT: Chevron R&D; COE Advisory Board

3 Chevron Shipping & Offshore R&D Drivers Overlapping Interests Leaps in Naval Engineering Education & Innovation AGENDA 3

4 Chevron R&D - Ships & Offshore Scope of Operations Chevron Operating Companies Manage tanker fleet (27) and FPSO vessels ( in development) Focus: fleet design, construction & operation Chevron Energy Technology Co. Offshore consulting & R&D: floating & subsea systems Focus: SME technical services to Bus. Units; R&D deepwater facilities Corporate University Support Domestic & international Local staffing sources

5 Shipping & Offshore Vessels Lightering Vessel LNG LPG Tanker Agbami FPSO (1,463m Nigeria) 5

6 Deepwater Installation Examples Lobito-Tomboco Compliant Tower (390m Angola) Discoverer Clear Leader Drillship Agbami Manifold Tahiti Truss Spar (1,280m GoM) Blind Faith Semi (2,130m GoM)

7 O&G R&D Drivers Ships & Offshore Facilities Shipping: Designed & built by shipyard; no outside engineering Yards located internationally for low cost Offshore facility drivers: Deepwater, harsh environment, costly operations Reliability, easy maintenance Primarily short term focus Freedom to operate Increased contractor capability Deepwater challenges Facilities supplied by others; cooperative effort

8 Key Naval Engineering Related Activities Ship design Safety; envir. protection; Green ships: CO2, coatings, Reliability; Integrity management Ship structures Double hull structural design; LNG containment Ship propulsion Electric propulsion; efficiency; DP drilling Advanced modeling: CFD-FEA (FSI) Acoustics & seismics Control systems; quiet operations Robotics ROVs, AUVs; inspection & maintenance Subsea systems Mooring, flow induced vibration, wave loads & sloshing Hindcasting & weather data; arctic operations

9 Large Scale FSI Modeling Spar VIM & Riser VIV Pull tube array Riser Vortex Induced Vibration & Suppression Vortex Induced Motion Wave Loads A/D vs t

10 Leaps in Naval Engineering & Cooperation Computing (desktops & clusters) CFD, Optimization Robotics & autonomous operations Commercial applications & cost reduction Engineered surfaces Low drag, clean, improved separation Instrumentation & inspection; Integrity Management systems Security (pirates, offshore facilities) Green operations (ships, facilities, seismics) System integration (new generation of engineers)

11 Hiring & Education Support Chevron Naval architects & ocean engineers (~2-3 shipping, 1s ETC) University support (R&D and grants) Industry societies (SNAME, ASME, offshore conf.) Trends ONR Domestic: No market for big iron Loss of NA&ME identity; reduced Ocean Engineering focus at major institutions Reduced source of NAs for US Navy & O&G International: Increased local focus for shipbuilding, offshore construction and research facilities Potential source for O&G operations Steady ONR university R&D support important 11

12 Education Premise: there is a limited but real need for NA and OE skills to meet the navy s and industry s challenges Radical changes in naval systems (electronics, computing, robots, etc.) less big iron Education Issues: Limit number of US NA s due to low industry demand look for alternative ways to source skills Growing no. of undergraduates with system integration, hands on capabilities (e.g. robotic design skills), but lacking in graduate school & with most foreign students Large percentage of US graduate students are from abroad; limited opportunity to work in US Alternatives: Look to our academies to supply navy s NA s that later go into the commercial world Increased cooperation between US and foreign schools/shipyards (exchange students) Expand the graduate education beyond analysis skills Enlarge the mobility of the work force (visas) 12

13 Innovation No lack of ideas & opportunities Handoff challenge Business case & long-term planning Support for field demonstration / maturing technology (e.g. RPSEA) 13
