  • Mapping sea ice overflood using remote sensing: Alaskan Beaufort Sea
    Cold Regions Science and Technology, 2011
    Co-Authors: David Dickins, Greg Hearon, Kim Morris, Ken Ambrosius, Warren Horowitz
    Abstract:

    The U.S. Department of Interior, Minerals Management Service (MMS), Alaska Outer Continental Shelf Region commissioned a study designed to map the extent of peak river overflooding onto the fast ice in the nearshore region of the Alaskan Beaufort Sea (Hearon et al., 2009). This phenomenon occurs annually during a brief period in the spring when the river stage increases rapidly as the snow pack melts, while the sea ice of the Delta front is still intact. River overflood constitutes a potential hazard to offshore oil and gas development, as it relates to facilities access, oil spill spreading, and the associated phenomenon of strudel drainage and potential seabed scouring. The overall goal of the study was to improve the knowledge of the spatial and temporal variability of overflooding and related Pipeline and Facility siting concerns. Historical overflood boundaries were mapped for the 13-year period from 1995 to 2007, using a combination of helicopter surveys and satellite imagery. Hazards associated with strudel scouring were assessed with strudel drain and scour databases developed for several industry projects. © 2010.

  • ACHIEVING DEPENDABILITY VALUE FOR PipelineS and FACILITIES
    Volume 4: Pipelining in Northern and Offshore Environments; Strain-Based Design; Risk and Reliability; Standards and Regulations, 2012
    Co-Authors: Thomas Van Hardeveld, David Kiang
    Abstract:

    In today’s competitive and changing environment, it is crucial that Pipelines and associated facilities create and sustain value for their stakeholders. This value can only be achieved by incorporating dependability into the Pipeline system, in whole or in part. Dependability characteristics address not just availability and reliability as the probability of successful performance, but also identify other potential risk exposures such as degradation and wear-out that advocate the need for maintenance and logistic support to sustain “problem free” Pipeline and Facility operation. Dependability engineering provides practical means and measurable targets for achieving value, which are then implemented by sound operational risk assessment practices. Dependability management is needed to present viable business success options on risk avoidance, prevention, and mitigation; and where applicable, provides cost-effective risk treatments to support Pipeline operation and enhance Facility management. Characterizing the value of dependability focuses on two key issues: (1) what is the value of dependability, and (2) what is required to achieve it. This paper establishes a unified approach for understanding the dependability principles and practices, and enunciates how dependability value can be ascertained and assured in real life situations. It presents a general framework and provides implementation guidelines for ensuring that dependability value can be achieved in practical application for Pipelines and facilities.Copyright © 2012 by ASME

  • A Staged Approach for Managing Terrain and Geohazards on New Pipeline Projects
    Volume 2: Pipeline Safety Management Systems; Project Management Design Construction and Environmental Issues; Strain Based Design; Risk and Reliabili, 2016
    Co-Authors: Mark Leir, Alex Baumgard, Katherine Johnston
    Abstract:

    Pipeline route selection and design is an iterative process by which one or more potential Pipeline corridors are systematically narrowed from the general path of about 10 km in width to a highly specified 30 m to 50 m wide corridor. The process usually spans several years, and is frequently becoming increasingly complicated, requiring a multi-disciplinary technical and managerial approach that considers the political and regulatory process, environmental impact and permitting, project and industry economics, access, constructability, land acquisition, and terrain. Specialist technical contributions to the Pipeline routing process include Pipeline hydraulics, Pipeline and Facility construction, terrain/geohazards, and environment/archaeology. Problematic terrain and geohazards are two of several issues that need to be managed through the feasibility and design of a new Pipeline project. As the project advances through Front End Engineering and Design (FEED) from feasibility to final engineering design and as the corridor narrows from kilometers to tens of meters in width, the level of detail required in ongoing terrain and geohazard investigations should increase to optimize the design process and match the increased detail being provided by other specialists. An idealized Four-Stage framework for managing geohazards and problematic terrain during Pipeline routing and design is outlined in the paper. This framework has been founded on several international resources listed in the references and has, by necessity, been developed, tested, and refined by the authors over the last ten years on several large and small diameter Pipeline projects in North and South America. Each of the 4 Stages is described and contains guidelines on project study scale, a target corridor width, the engineering design level, cost accuracy, and geohazard related engineering tasks and deliverables. This staged approach is provided as a road map to help guide all project participants including owners, project managers, engineers, scientists, and regulators to understand how geohazards and problematic terrain are managed through the Pipeline routing and design process.
