Spanning Canada and the United States, North America is home to a plethora of major industry players, including Exxon Mobil Corp, the world's second-largest publicly traded company after Royal Dutch Shell. The region's oil and natural gas industry is focused on developing oil sands, deepwater gulf prospects and increasingly profitable shale deposits stretching across the continent. One of the premier sweet spots for deepwater exploration, the Gulf of Mexico is the largest body of water indenting the U.S. continental coastline, and its subsea developments continue to spark both national and international interest.
Heavy Lift describes marine installation of heavy equipment such as topsides and production equipment. There are different methods of heavy lifting used in the oil and gas industry, including heavy lift barges, which uses cranes to move equipment and floatover installation, which uses a semi-submersible vessel to lower itself under water to move the equipment into place. Pipelay involves laying pipe on the ocean floor to connect production platforms to shore. Many different types of vessels can carry out this function, but they require a heavy lift crane.
