Seismic Hazard Analysis for Lengo WHP Location, Indonesia

The Seismic Hazard Analysis for the Lengo WHP Location, Indonesia was conducted to evaluate seismic hazards at the offshore facility site and support the development of structures designed to withstand earthquake effects. The scope of work included seismic hazard assessment, evaluation of regional seismic and geological conditions, development of design response spectra and earthquake acceleration parameters, and assessment of seismic response for offshore facilities. Key challenges included regional seismic activity affecting offshore infrastructure, the need for site-specific seismic parameters, and structural stability under combined seismic and marine environmental conditions. The technical approach involved evaluating regional seismicity and geological characteristics, developing site-specific response spectra and seismic acceleration parameters, and providing seismic design recommendations to support safe, reliable, and fit-for-purpose offshore structures.
