The largest port is Valdez, at the southern terminus of the Trans-Alaska Pipeline System
Prince William Sound is a sound off the Gulf of Alaska on the south coast of the U.S. state of Alaska. It is located on the east side of the Kenai Peninsula. The largest port in Prince William Sound is Valdez, which is situated at the southern terminus of the Trans-Alaska Pipeline System. Valdez is also the northernmost ice-free port in North America.
Valdez has played a significant role in the history of the region, including the devastating 1964 Good Friday earthquake and tsunami that resulted in the deaths of 32 people in the city and the destruction of its harbour and docks. In 1977, Valdez experienced a boomtown atmosphere due to the construction of the Trans-Alaska Pipeline, which attracted tens of thousands of workers with the promise of high wages, long work hours, and paid-for housing.
The Trans-Alaska Pipeline System (TAPS) is an engineering marvel and one of the world's largest pipeline systems, spanning approximately 800 miles (1,287 km) and transporting oil from Alaska's North Slope to Valdez. The pipeline traverses rugged terrain, including three mountain ranges, three major earthquake faults, and hundreds of rivers and streams.
The southern terminus of the Trans-Alaska Pipeline in Valdez gained attention in 1989 when the tanker Exxon Valdez ran aground in Prince William Sound, resulting in a massive oil spill. The spill caused significant environmental damage, killing hundreds of thousands of seabirds, sea otters, harbour seals, bald eagles, and whales. It is considered one of the worst human-caused environmental disasters in history.
Despite the challenges and controversies, the Trans-Alaska Pipeline System remains a vital component of Alaska's economy and the nation's energy infrastructure, transporting a significant portion of the country's crude oil supply.

Other settlements include Cordova, Chenega and Tatitlek
Prince William Sound is a sound off the Gulf of Alaska on the south coast of the United States state of Alaska. It is located on the east side of the Kenai Peninsula. Prince William Sound contains numerous small islands and has several settlements, including the port city of Cordova, and the villages of Chenega and Tatitlek.
Cordova is a port city in the Chugach Census Area of Alaska. It lies near the mouth of the Copper River, at the head of Orca Inlet on the east side of Prince William Sound. The city was named after the Orca Inlet, which was originally called Puerto Cordova, after the Spanish explorer Salvador Fidalgo. Cordova first appeared on the 1910 U.S. Census as an incorporated city, with a population of 2,454 people. As of the 2020 census, the population was 2,609. Commercial fishing is the main industry in Cordova, with half of all households having at least one person involved in commercial fishing or processing. The fishing fleet mainly fishes in the Prince William Sound and Copper River Delta area. The city hosts several festivals throughout the year, including the Copper River Wild Salmon Festival and the Salmon Jam Music Festival.
Chenega was originally a village located on the south end of Chenega Island. It first appeared on the 1880 U.S. Census as an unincorporated Sugpiaq village, with all 80 residents being Sugpiaq/Alutiiq. The village was largely destroyed in the Good Friday Earthquake of 1964, which triggered a tsunami that killed 26 residents, a third of the population at the time, and levelled all the buildings in the town except for one house and the school. Following the tsunami, survivors were taken to Cordova, and they were later permanently resettled at Tatitlek. A new village, Chenega Bay, was first occupied in 1984 and appeared on the 1990 U.S. Census as a census-designated place.
Tatitlek is a village located in Prince William Sound, most famously known as the nearest village to the 1989 Exxon Valdez oil spill that decimated the area's fishing resources. The village first appeared on the 1880 U.S. Census as the unincorporated village of "Tatikhlek", with all 73 residents listed as Inuit, despite being Chugach Alutiiq. In 1980, it was made a census-designated place. Within its boundaries is the former mining village of Ellamar.
