COST COMPARISON OF BREAKWATER TYPES

W.H. Tutuarima, K. d'Angremond

Abstract


A cost comparison have been made between various types of breakwaters for a fictitious situation in water depths to a local maximum of -15 m and an adopted sea climate. The comparison is based on optimal total project costs, being the sum of costs of construction and capitalized damage during the service period. For these selected conditions the caisson breakwater and the rubble mound type provided with a single concrete armour layer appear most attractive. Composite type of breakwaters seem advantageous for water depths approximately below -20 m.
