Comments

Constitution, located on Green Canyon block 680, was sanctioned in January 2004. The Constitution truss spar called the Global Producer X, will be located in a prime position to provide a strategic hub for third-party business in Ticonderoga on Green Canyon block 768. The spar has a daily production capacity of 70,000 barrels of oil and 200 million cubic feet of gas. This new spar is 169 m (554 ft) long and 30 m (98 ft) in diameter, which is similar to Kerr-McGee's Gunnison truss spar.

Two (2) subsea wells from Ticonderoga are tied back to the Constitution spar.
