Crowley Maritime Corporation

While Crowley was moving equipment and supplies over water during the summer months in support of the North Slope, in the winter they were also providing additional logistics support with Crowley All Terrain Corporation (CATCO) vehicles. These heavy-lift, overland transport units were first acquired by Crowley in 1975 and were suitable for all types of remote off-road transportation, including over ice and snow fields in the winter as well as delicate tundra in the summer. The large low-pressure bag tires were specifically designed to work on the delicate tundra without damaging it. The all-terrain vehicles were used as a total support system for drilling operations. They were employed to transport extremely heavy equipment, materials, water and personnel and were also used in drilling-rig support, and in the pioneering stages of ice road construction. The CATCOs came in two versions (RD 85 and RD 105), which were identical except that the RD 105 had a fifth set of tires installed under the cargo dock raising the vehicle's payload capability by 15,000 pounds. Both versions had 54-by-68 inch airbag tires with no tread and independently controlled air pressure. In 2011, Crowley sold its CATCO units to Peak Oilfield Services Co., allowing Crowley to focus on its traditional marine services and project solutions business lines. Tornga.

The operation, which has Crowley tugs tethered to, or shadowing, laden tankers through Prince William Sound and Hinchinbrook Entrance to Seal Rocks, was put in place in 1989 by Alyeska following the cleanup of a major oil spilled caused by a tanker striking Bligh Reef. To prevent this from happening again, "We enjoyed a long successful history with our CATCO operations on the North Slope," said 7
