Wave energy resource in the Pacific
Cyprien Bosserelle, Tom Durrant, Sandeep Reddy, Jens Kruger
Spatial/temporal analysis of wave parameters
19th Nov 2013 Pacific Island Countries GIS and RS User Conference

Motivations
Coastal hazards (inundation, erosion)
• Hazard mitigation• Coastal planning and development• Disaster management• Water and sanitation
Why are we studying waves?

MotivationWave energy could play an important role in the development of Pacific Island nations
How reliable is wave energy in the region and where to install what device?

Method: Wave hindcast• Simulation of waves in the past
• Global to regional scale
• 1979 to 2013
• Wave Watch III model (State of the art wave simulation)
• Wind from NOAA-CFSR reanalysis• Hourly wind hindcast• High spatial resolution (0.3deg)• Includes cyclones (crude)

Method: Nearshore wave hindcast• Simulation of waves in the past using the global
wave hindcast
• Fine scale (100-300Km)
• Simulating Wave Nearshore (SWAN)
• Selected locations:• Western Samoa• Tongatapu (Tonga)• Fiji (Viti Levu, Kadavu)• Efate (Vanuatu)• Funafuti (Tuvalu)• Rarotonga (Cook Islands)

Take home messages• Wave climate in the Pacific region is one of the most complex in the world
• Wave energy is reliable and a commercially viable resource in most of the region (except PNG, Solomon)
• Offshore assessment can be realistic for islands with steep offshore slopes but nearshore analysis is need for larger island with gentler slopes
Future Work• Local wave energy and hotspot for 6 islands of the Pacific region
• Simulation of the energy output of:• Wave Oyster• Palamis• CETO
• Cost-benefit assessement
