Hebron Offshore Development Project Overview

摘要

The Hebron Offshore Development Project, offshore Eastern Canada, is one of the world's most ambitious oil projects. In November 2017 ExxonMobil Canada Properties (EMCP) commenced oil production from this world scale engineering marvel located in 93m of water approximately 350 kilometers southeast of St. John's NL in an area known as the Grand Banks. The Hebron platform consists of a Gravity Based Structure (GBS) with a storage capacity of 1.2 million barrels of oil and an integrated steel topsides structure. The integrated topsides design with total operating weight capacity of ~65,000 t contains drilling and production facilities with a peak production capacity of 150,000 barrels per day (bpd) and a living quarters for 220 people. The field infrastructure also includes a subsea Offshore Loading System (OLS) providing crude offloading capability to tankers and a fiber optic cable loop linking the offshore platform to an onshore network enabling enhanced digital technology implementation. The project was sanctioned on 31 December 2012 and first oil occurred on 27 November 2017, ahead of schedule. This paper discusses the Project from design through execution and highlights several of the unique design features, execution sequence and specific challenges which were faced. Special technologies were employed and project management initiatives implemented which enabled the success of the project.
