It's 1,549 feet tall.

  1. Hibernia, off Newfoundland is heavier.
    Hibernia is an oil field in the North Atlantic Ocean, approximately 315 kilometres (196 mi) east-southeast of St. John's, Newfoundland, Canada, in 80 m of water.[1]:35–36

    The production platform Hibernia is the world's largest oil platform[2] (by weight) and consists of a 37,000 t (41,000 short tons) integrated topsides facility mounted on a 600,000 t (660,000 short tons) gravity base structure. The platform was towed to its final site, and 450,000 t (500,000 short tons) of solid ballast were added to secure it in place. Inside the gravity base structure are storage tanks for 1.3 million barrels (210,000 m3) of crude oil
