Objective � Discuss integration of marine transportation planning and engineering design of very large modules (1,000MT and greater) for future developments in the Athabasca Oil Sands � Discuss the key parameters of the marine route, the typical marine equipment available for such an operation and the affect of these parameters on engineering design and project capital cost
Presentation Overview � Marine Transportation Overview � Review design constraints associated with the marine transportation route � Overview of applicable marine equipment � Possible transportation scenario � Discussion of module design considerations � Next Steps

Developing the Athabasca Oil Sands � The current construction scenario for Athabasca Oil Sands projects relies on a combination of module assembly on site or transportation of southerly constructed small modules by road and rail � These methods have some of the following drawbacks: � high labour rates during the fabrication and on-site hook-up � limited labor market � module size is limited by transportation restrictions
Developing the Athabasca Oil Sands – Marine Transport Option � Access to marine transportation allows Oil Sands Projects to: � Take advantage of international fabrication market rates � Reduce reliance on the stressed Canadian labor market � Potential capital cost savings and improved project schedule through application of Very Large Module Design
Marine Transportation for Athabasca Oil Sands Projects 1. Pacific Transportation 2. Arctic Transportation 3. River Transportation
Pacific Transportation Far East Fabrication
Pacific Transportation Gulf of Mexico Fabrication
Pacific Transportation Design Parameters � Environmental criteria � Design sea state (ie. wind speed, wave height, wave period) � Tropical storms � Arctic ice-free season � Voyage route � Panama canal restrictions � Draft limitations � Marine equipment � Transportation loads / accelerations � Transit speed and duration � Cargo capacity � Stability � Availability
Arctic Transportation: Point Barrow to Mackenzie Bay
Arctic Transit Design Parameters Environmental criteria � � Less severe design sea state (ie. wind speed, wave height, wave period) � Arctic ice-free season Marine equipment � � Ice Breaker / Ice Management Vessel � Air ice reconnaissance and surveillance program � Ice monitoring and forecasting program � Equipment selection and availability Inside passage � � Draft limitations (shallow water) � 6 weeks long, typically starting August 1 st � 6 days dependent on ice concentration Outside passage � � No draft limitation (deeper water) � 5 weeks long, typically starting August 15 th � 6 days dependent on ice concentration
River Transportation River Voyage Stage 1: � Beaufort Sea to Bell Rock, NWT River Voyage Stage 2: � Slave River rapids portage River Voyage Stage 3: � Fort Fitzgerald, AB to Athabasca Oil Sands
River Voyage Stage 1: Mackenzie River Design Considerations � Ramparts and Sans Sault rapids � Fort Providence rapids � Deh Cho Bridge restrictions � Marine equipment selection and availability
River Voyage Stage 1: Great Slave Lake / Lower Slave River Design Considerations � Possible dredging requirements in Res. Delta Channel
River Voyage Stage 2: Slave River Rapids Portage Design Considerations � Infrastructure development at Bell Rock and Fort Fitzgerald � development of put-in and take-out locations � upgrade of portage road � Availability of land transportation equipment � Availability of marine equipment on both sides of portage
Bell Rock to Fort Fitzgerald Portage
Typical Land Transportation 900 TONNE MODULE ON ALL-SEASON 1,200 TONNE MODULE ON ICEROAD ROAD
River Voyage Stage 3: Upper Slave River
River Voyage Stage 3: Peace River and Quatre Fourche Channel to Athabasca Delta Design Considerations � Quatre Fourches Channel to Fort Chipewyan � Possible dredging requirements in Athabasca Delta
River Voyage Stage 3: Athabasca River Design Considerations � Peter Lougheed Bridge at Fort Mackay � Take out location and land transportation to site
Transportation Durations Days Pacific Voyage: 15 – 30 Dependent on fabrication yard selection and marine equipment selection Arctic Voyage: 6 Point Barrow to Mackenzie Bay Area River Voyage Stage 1: 17 Mackenzie River Delta to Bell Rock Stage 2: 4 Slave River Rapids Portage Stage 3: 4 Fort Fitzgerald to Athabasca Oil Sands (Fort Mackay) River durations may be conservative, but are meant to account for expected delays along route due to � weather and river conditions.
