These buoys presently use a wave observation system named the Digital Directional Wave Module (DDWM). The DDWM uses commercial motion sensors contained in a single package and processing boards that are now obsolete. Therefore, the NDBC completed an engineering effort to replace these obsolete components with a new wave observation system named Ocean Wave Linux (OWL).The OWL replaces the DDWM’s nine axis motion sensor with a compatible device. The OWL produces the same observations as the DDWM but with much less power consumption and with modern COTS available components.The DDWM is contained in a single tube named WAVCEAN-16, which is a payload in the NDBC’s Self-Contained Ocean Observation Payload (SCOOP). WAVCEAN-16 physically contains the Wave and Ocean (which measures sea surface temperature) modules. After extensive, successful field trials, the OWL components replaced the DDWM components. This effectively created a new tube or product. The new tube is named WAVCEAN-18.This paper focuses on the changes from WAVCEAN-16 to WAVCEAN-18 and highlights engineering analysis of field tests of the WAVCEAN-18. We also describe the NDBC’s plans for operational transition from the WAVCEAN-16 to WAVCEAN-18.KEYWORDS: OWLWavesDDWMNDBC Disclosure statementNo potential conflict of interest was reported by the author.","PeriodicalId":50673,"journal":{"name":"Coastal Engineering Journal","volume":"78 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135036980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
