17 Innovation Long history of involvement with Mooring R&D and has led the industry in innovative thinking that has resulted in many technological advancements for the oil and gas industry. Pioneer in the use of Deepwater Pre-Set Moorings to increase efficiency and water depth capabilities of floating vessels with the development of suction anchors, the patented SEPLA (Suction Embedded PLate Anchor), and polyester rope and taut-leg moorings. Currently involved in multiple joint industry projects, industry committees and forums contribution to the development and improvement of the offshore industry's practices and technologies. 17

18 Innovation SEPLA Anchor Combines advantages of suction embedment and proven plate anchor technology Uses suction embedment follower with plate anchor slotted into base to install plate anchor Follower is then removed by reversing pump action, leaving plate at depth Plate is then rotated to orientation close to perpendicular to direction of load Geotechnically efficient shape 18

19 Innovation SEPLA Anchor COMPARISON: MODU Example: Suction Anchor SEPLA 2,90m diameter x 21,30m 2,45m x 6,10m Weight 68 tons Weight 24 tons (solid fluke) Permanent Mooring Example (Red Hawk Spar) Suction Anchor SEPLA 5,50m diameter x 23,80m 4,60m x 9,15m Weight 180 tons Weight 37 tons (hollow fluke) 19

20 Mooring Design MODU MOORING DESIGN AND RISK ASSESSMENT: MODUs have gotten bigger and staying at one site for longer periods of time. There are more permanent deepwater production systems with higher production rates. There is much more subsea infrastructure. Governments, regulatory agencies, companies and the general public have put more emphasis on protecting the environment and offshore assets. Hurricane and typhoon design criteria and regulatory requirements have become more stringent. InterMoor's extensive understanding of mooring components, installation methods, and analytical simulations means we can evaluate the probability of failure, consequence of damage and the associated risk to deliver robust, reliable, and cost effective mooring systems. 20

22 Forecast Mooring Maintenance: Mooring Integrity Management (MIM) Maritime history shows that permanent mooring fails in a wide range of WD and environmental conditions Records show that failures are caused by a variety of mechanisms (wear, fatigue, abrasion, corrosion, damages from installation operations, inspection operations, and dropped objects, flawed materials, excessive tension, etc.); Statistics at North Sea show that the probability of failure per operating year is relatively high; Statistics also shows that most part of units cannot monitor line tension or offsets, do not have line failure alarms or adjust line lengths or have spare parts available; Mooring integrity is gaining interest: it is not acceptable for a permanent production unit to be with a damaged mooring system; 22

23 Forecast Mooring Maintenance: Mooring Integrity Management (MIM) Interest in MIM becomes more prevalent; MIM programs tailored to encompass: regular inspection and evaluation of mooring system in-place condition Identification and execution of routine maintenance operations to reduce potential of failures Analytical prediction of a mooring line s probability of failure based on mooring system condition, line measurements, previous real world operating and survival conditions and Mooring repair plan (MRP) to identify market installation vessels, mooring suppliers, installation suppliers, develop operations procedures to repair line components before or after failure occurs with little or no production loss down time Procurement, fabrication, storage and maintenance of spare mooring components and installation aids; The majority of existing Units assets are installed and operating WITHOUT mooring system monitoring and load measurement. The integrity is based only on inspection and maintenance; 23

24 Forecast Mooring Maintenance: Mooring Integrity Management (MIM) MIM for New Units should not only include a inspection, maintenance and MRP. There is the opportunity to augment the system in a real time line measurement equipment to realize a comprehensive MIM program. InterMoor has developed the Inter-M-Pulse direct in line tension monitoring system. The system send the real time measurement to control room, detailing line inclination, orientation and curvature of mooring line; For new Units, a comprehensive MIM could be developed before the failure occurs, offering the opportunity to monitoring systems for more accurate and predictive probability of failure estimates (using real time mooring line measurement and monitoring system). 24
