Life Extension of Offshore Field in the Santa Barbara Channel 1: Simultaneous ICCP Retrofit of Three Jacket Platforms

Product Number: 51323-18978-SG

Three platforms in the Santa Ynez Unit (SYU) field in the Santa Barbara Channel, platforms Heritage (HE), Harmony (HA), and Hondo (HO), were installed between 1979 and 1989, approximately 19 km (12 miles) west of Goleta, California in water depths between 259 m (850 ft) to 365 m (1200 ft). These platforms were previously retrofitted with ICCP sleds which were in decline, requiring additional Impressed Current Cathodic Protection (ICCP) anode output. Therefore, they were all retrofitted with additional ICCP systems in a single campaign to provide a 25-year life extension.

Life Extension of Offshore Field in The Santa Barbara Channel 2: Multi-Objective Optimization of Retrofit ICCP Anode Sled Placement Using Calibrated 3D Simulations

Product Number: 51323-19382-SG

The life of offshore jacket structures can be extended up to 30 years towards the end of their design life by retrofits. For larger structures, and in unusual cases, semi-remote ICCP anode sleds are a favorable option compared to sacrificial anode cathodic protection (SACP) due to the high current output from each individual installation, reducing the time to install substantially. Anode sled locations are determined based on site plans, experience, survey data, and equations evaluating “remoteness” or “voltage rise” criteria.
