Connecting What’s Needed with What’s Next TM oceaneering.com Case Study Project Overview Oceaneering was contracted by a customer for the design, manufacture, factory acceptance test, and delivery of a 1-mi (1.6-km) length of power and optical fiber subsea cable for the renewable energy sector. The cable was divided into two sections consisting of a 656-ft (200-m) dynamic length and a 4,593-ft (1400-m) static length. Both were spooled onto a steel, road-transportable reel bound for a field offshore of Jeju Island, the largest island off the coast of South Korea. We offered a series of verification testing and were awarded the scope to verify the fatigue performance of the submarine cable. A comprehensive flex fatigue test regime consisted of 100,000 single bend cycles over
