This model of the Mohole drilling platform represents a considerable advance in the design and construction of drilling platforms. It was designed by Broon&Root, prime contractor for the Mohole Project Phase II. The largest and most sophisticated ever proposed, the upper platform is approximately 280 feet long and 235 feet wide. The huge vessel stands 135 feet from keel to upper deck, with the drilling derrick towering 240 feet higher. The long submarine-like lower hulls are 390 feet long and contain the main engines, which will propel the vessel at speeds up to 10 knots. The platform is designed to maintain position and continue drilling operations even in gale-force winds of 33 knots. Highly stable, the vessel can even ride out storms of hurricane force
