Mobile offshore base

What do you think about this mobile offshore base concept?:

Ference.

The Joint Mobile Offshore Base (JMOB) will enhance the ability of the United States to provide logistical support for the projection of power and aid worldwide. At the same time, it will lend greater security to the men and women on it. And compared with traditional land bases, this moveable, reusable investment is not subject to the politics of other nations, enabling military equipment to be prepositioned in the theater of interest within 30 days nearly anywhere in the world.

– Self-powered, semisubmersible supply and theater vessel.
– Five individual single-base units, each 1,000 feet long, connected together to form a one-mile floating runway 500 feet wide and 120 feet above the ocean surface.
– Deployed as five single-base units at 15 knots; 30 days from U.S. to operation anywhere in the world.
– Survivable in all sea states (50-foot seas with 100-knot winds).
– Total of 5 million square feet, with 3.5 million square feet (80 acres) of climate-controlled storage space to preposition 300,000 tons of equipment and supplies with 75 million gallons of fuel and 50 million gallons of potable water.
– All materiel directly available for on-board operation prior to theater use.
– JMOB has an amphibious-launch-compatible “artificial” beach.
– Below-deck roadways between units.

McDermott’s JMOB concept consists of five semisubmersible single-base units (SBUs), each one a thousand feet long, that can be connected and disconnected at sea under their own power. The five-unit JMOB, fully connected end to end, is nearly a mile long and capable of supporting air operations of a variety of fixed- and rotary-winged aircraft (including the C-17 cargo plane) on its 500-foot-wide runway about 120 feet above the water. Capacities include:

– Stable base holding 3,500 vehicles, 5,000 containers, and 150 aircraft. The stowed equipment, supplies, and containers can be completely accessed within the JMOB.
– A total of 5 million square feet, with 3.5 million square feet (80 acres) of climate-controlled storage space to preposition 300,000 tons of equipment and supplies with 75 million gallons of fuel and 50 million gallons of potable water.
– Ten all-purpose berths for ocean-going supply vessels and combat ships.
– A transit speed of 15 knots, enabling individual units to be in theater from the U.S. anywhere in the world within 30 days.
– A capability to transfer cargo in waves up to Sea State 4. Cargo operations will accommodate all modern commercial and military cargo vessels, including container ships, roll-on/roll-off, break bulk, and tankers. The JMOB can conduct lighterage cargo-handling operations to landing craft and causeways up to Sea State 3 or to the operational limits of the lighter.
