Why is Shell's Perdido platform considered an important offshore engineering achievement?

Shell's Perdido platform is considered a significant offshore engineering achievement because it set a record as the world’s deepest floating oil platform upon its deployment in the Gulf of Mexico.

Placed in 2,450 metres (8,000 feet) of water by 2014, the platform represents a major milestone in the evolution of petroleum engineering and the industry's ability to operate in ultra-deepwater environments. The development of such infrastructure was made possible by the work of engineers who, following the industry downturn of the late 20th century, focused on creating advanced equipment capable of exploring and extracting resources from these extreme depths.1
