A Typhoon Ridden Archipelago

Source: 2006 Riso-DTU Study

The Philippine Island sits inthe typhoon belt of South-East

Asia

An annual average of 20

typhoons enter the PhilippineArea of Responsibility, of which

an average of 9 typhoons make

landfall.

Typhoon season normallyoccur starting in the months of

June and ends in November.

Technological Advancement

ROTOR

Lighter, more flexible and longer blades with

increased strength

Advanced aerodynamic blade design that increase

lift and distribute loads

Aeroelastically designed blades that addresses

increased fatigue loads

Pre-bent blades to enable blade deflection

Tower and Foundation

The wind turbine structure that makes sure the

turbine stands upright at all weather condition.

Use of tapered tubular steel for tower has been

the standard platform

Full pre-cast concrete or concrete/ steel hybrid

towers are coming up the market catering for taller

and heavier turbines

Different types of foundation designs are

available

Summary

Although there are a number of challenges in the development of

wind farm in the Philippines primarily due to its location, weatherpattern and topography, the technological advancements and

progress presented here shows that such factors can be

mitigated.

From the longer, flexible and stronger blades, to the permanent

magnet direct drive generators, as well as bigger vessels and

O&M strategies, such technologies and services are present

to support the need of local developers.
