In November of 2012, a Dockwise heavy lift vessel departed South Korea in route to the U.S. Gulf of Mexico carrying the 35,000 ton main body of Shell's Olympus TLP. The TLP arrived at the Kiewit Offshore Services yard in Ingleside, Texas early in 2013 where the topsides were installed before being towed to its final location in the Shell-operated Mars project.

Olympus will be the company's largest tension leg platform designed with 24 well slots and will provide infrastructure to the West Boreus and South Deimos subsea developments. The addition of Olympus will extend the life of the Mars field to at least 2050. Production is targeted for 2015.The Olympus TLP is the largest ever deployed in the Gulf of Mexico. According to Shell officials, the project will be the first in the region to employ an additional floating production system in a producing deepwater field.

The project is expected to extend the field life of Mars to at least 2050 and could contain recoverable reserves of 1.1 Bboe.
