Since 2004, Crowley has hauled a majority of the 10 million pounds of trash leaving the area, a service Crowley donates much of the costs for. Crowley's current tug and barge services provide fuel and general cargo delivery to about 150 remote Alaskan villages. But delivering these necessities isn't all the company does – it also has made good use of its vessels to remove stockpiles of junk, including old cars, dated snow machines, lead-acid batteries and broken electrical appliances from the Yukon watershed area. The combo fuel/deck cargo barges stop by villages to haul away the accumulated rubbish on the way back from fuel deliveries, providing a critical service to these remote villages. Since 2004, Crowley has hauled a majority of the 10 million pounds of trash leaving the area, a service Crowley donates much of the costs for – $80,000 in 2010 alone. "The remote nature of Alaska, as well as the villages and projects that Crowley supports, has been, is and will continue to be challenging. But we know in many cases that Crowley provides a lifeline to Alaskans in remote locations that they wouldn't otherwise have," said Smith. "To that end, we are committed for the long-term, as we have been for so many years, and will not waver in our support of Alaska, its people and its business." Throughout the last 60 years, unique expertise and equipment have propelled Crowley into its position as a leader historical highlight: 2011 11,000 Tons, 3,000 Nautical Miles Crowley Tackles the Parker AADU Sealift The Parker AADU sealift consisted of the movement of two Arctic Alaskan Drilling Units, collectively weighing more than 10,000 tons, from Vancouver, Wash., to Prudhoe Bay, a trip of more than 3,000 nautical miles. Crowley's solutions group was hired as the prime contractor to manage the project from start to finish, which meant coordinating the people and service providers, ever-changing schedule and equipment to meet customer requirements. Predicted risks upon arrival on the North Slope included navigating the "shallows" – a 2,000-yard stretch of water less than two-meters deep – high winds, and low visibility. But flooding on Washington's Columbia River from heavy snowfalls and rain weren't part of the equation and delayed the project for a month. Intense planning and innovation were the keys to success for solutions. The team orchestrated the loading of both rig's six main modules onto the company's heavystrength deck barge 455 5, for the tow from the Columbia River to the North Slope by the Crowley tug Guardsman. Upon arrival in Prudhoe Bay, the 455 5 was ballasted down and grounded offshore in 13 feet of water to remove unsafe dynamic elements that can be present with an ungrounded, floating vessel in currents, waves and winds. Still under solutions' direction, the sister vessel 455 4 loaded with the rig's camp units and shops resulting in a much lighter draft, was towed to Prudhoe by the tug Hunter, and brought into the dock for unloading. The empty 455 4 was then ballasted down and grounded offshore, stern to stern with the 455 5. Offering a second stable platform, each of the six self-propelled modules were transferred one at a time onto the 455 4. With a single, lighter load, this sister barge had a lesser draft and was pushed through shallow waters by Crowley's four shallow-draft tugs, Avik, Kuparuk River, Kavik River, and Sag River (a process called "lightering"). Precise timing with the tides allowed the deballasted, refloated 455 4 to squeak through the shallows of less than five-and-a-half feet of water. This was repeated safely four more times, with the 455 5 bringing in the final module. continued on page 16 15
