OTEC Thermal Resource Report for Manila, Philippine Islands

摘要

An examination of the historical oceanographic data for the waters off Manila, Philippines shows that there is an excellent thermal difference resource for OTEC purposes. The region examined was between 14--16 exp 0 N latitude and 118--120 exp 0 E longitude, which is off the west coast of the island of Luzon. Surface temperatures are high the year round, with the lowest monthly mean surface temperature being 27.2 exp 0 C. The average of the monthly mean delta Ts to 1000 meters is 24.0 exp 0 C. At 500 meters, the annual thermal difference resource is 20.0 exp 0 C, so that the cold water pipes can be relatively short. The continental slope off the Philippines is steep, and water depths of 1000 meters lie within 18.5 km (ten nautical miles) off the shores of Luzon. There is an adequate upper mixed layer throughout the year. Typhoons are a major problem for this area. High winds and storms are a bigger problem for this site than any other site studied under the current contract. Seismic activity also occurs. Currents are generally moderate with some variation during the year. (ERA citation 04:042662)
