| Résumé | Experimental studies in a wave basin are described with emphasis on wave impact on jacket platform decks and related structures in the Ekofisk field off Norway. The paper identifies a number of considerations related to the design of scaled physical models to be used in wave tests measuring impact loads. Special procedures for measurement of wave forces as well as techniques used for data analysis, specifically to remove extraneous effects introduced by the model's response to impact loads, are presented. Influence of the large protective barrier on wave crest characteristics around the structure are also provided in the paper. Results and discussion provide information on impact phenomena on various types of offshore structures, apart from the particular one used in the paper. |
