Cartagena, Spain

Project name

C10 Expansion of Refinery

General project description

The safety of people and the facilities in which they work is the highest priority of the expansion project for the Cartagena refinery. Due to this, one of the principle demands was the installation of a modern and comprehensive warning and general alarm system. The Spanish oil company states that the € 3.2 billion figure is the refinery sector's biggest investment in a conversion in recent years. The refinery has a present capacity of 100,000 barrels per day (bpd) and is set to yield 220,000 bpd or 11 million tonnes a year after the investment. Repsol expects the complex to become one of the world's most modern refineries.
