Alyeska Pipeline Service Company

What Alyeska Pipeline Service Company does

Alyeska Pipeline Service Company is a privately held Alaska corporation founded in 1970 to design, construct, and operate the Trans Alaska Pipeline System (TAPS), an 800-mile crude oil pipeline running from Pump Station 1 at Prudhoe Bay on the Alaska North Slope to the Valdez Marine Terminal. The company employs approximately 700 people (94% Alaska-based, approximately 25% Alaska Native) and operates from offices in Anchorage, Fairbanks, and Valdez. TAPS has transported more than 19 billion barrels of Alaska North Slope crude since startup on June 20, 1977, with current throughput averaging approximately 462,000 barrels per day, down from a 1988 peak of 2.1 million BPD.

Alyeska's core technology stack centers on physical midstream infrastructure: four operational pump stations (PS1, PS3, PS4, PS9) out of eleven originally built, the Valdez Marine Terminal with 6.6 million barrels of storage across 13 active tanks, flow assurance systems managing wax deposition and crude temperature at low throughput, and scraper pigging operations every 7-14 days. The Ship Escort Response Vessel System (SERVS), created after the 1989 Exxon Valdez spill, provides marine spill prevention and response capability with 10 escort tugs, 7 oil recovery barges, and capacity to recover 300,000 barrels in 72 hours. Edison Chouest Offshore operates the marine fleet under a partnership established in 2018.

Alyeska generates revenue by charging pipeline transportation tariffs to the TAPS owner companies, which as of January 2025 are Harvest Alaska LLC (49.1069%), ConocoPhillips Transportation Alaska Inc. (29.6102%), and ExxonMobil Pipeline Company LLC (21.2829%). These same owners are the company's only customers; Hilcorp is also a participant through ownership stakes. Pricing is not publicly disclosed and is governed by negotiated arrangements between the owner consortium. Revenue figures are not publicly disclosed, and the company operates as a single-purpose midstream service provider with no other product lines or market-facing sales motion.

Regional players

• Hilcorp Energy: Hilcorp is a major Alaska-focused operator and TAPS owner/participant. It is comparable as a North Slope producer that depends on TAPS as its only export route and is also a customer of Alyeska's services.

Direct peers

• Plains All American Pipeline: Plains operates extensive North American crude oil gathering, transportation and storage assets. Comparable to Alyeska as a tariff-based midstream operator with focus on crude oil movement from producing basins to refining and export markets.
• Energy Transfer: Energy Transfer owns and operates one of the largest and most diversified portfolios of energy infrastructure in the U.S., including crude and NGL pipelines. Comparable as a fee-based long-haul crude/liquids pipeline operator with major oil and gas producers as customers.
• Kinder Morgan: Kinder Morgan operates one of the largest U.S. networks of crude oil, refined products and CO2 pipelines. Like Alyeska, it is a fee-based midstream operator with long-haul transportation assets serving major integrated and independent producers.
• Colonial Pipeline: Colonial Pipeline operates the largest refined products pipeline in the U.S. While its commodity is refined products rather than crude, it is highly comparable to Alyeska as a strategically critical, single-asset long-haul pipeline system serving concentrated East Coast markets.
• Enterprise Products Partners: Enterprise is a major North American midstream MLP with extensive crude oil, NGL and refined products pipelines, plus marine terminals. Comparable to Alyeska in operating large-scale pipeline infrastructure with marine loading and storage tied to crude exports.
• Enbridge: Enbridge operates the largest crude oil pipeline system in North America (Enbridge Pipeline / Mainline), transporting Western Canadian and U.S. crude. Both Alyeska and Enbridge run large-scale, long-haul crude oil pipeline systems on a tariff-for-service basis with concentrated shipper bases.

Broad incumbents

• TC Energy: TC Energy (formerly TransCanada) operates large-scale pipeline systems across North America focused primarily on natural gas and liquids. Comparable as a major regulated/unregulated pipeline operator with similar long-distance transportation contracts and customer base of large producers.

Others

• ConocoPhillips: ConocoPhillips is a 29.6% TAPS owner and the largest operator on the Alaska North Slope. Comparable as the dominant Alaska upstream producer whose drilling activity directly determines Alyeska's throughput and revenue trajectory.
• Harvest Alaska LLC: Harvest Alaska is both Alyeska's largest customer (49.1% TAPS owner) and operator of midstream assets on the North Slope. It is comparable as a customer relationship and as an Alaska-focused midstream operator using TAPS as its primary export route.
