註釋"This paper was commissioned by the Beaufort Sea Alliance. It attempts to review and summarize the evidence on proposed icebreaking LNG carriers as presented at the National Energy Board's hearing on the Arctic Pilot Project in 1982. It relies almost wholly on the transcript of spoken testimony; filed exhibits are referred to in some places where they provide useful summaries of facts, but for a full understanding of the issues and proceedings the reader should also consult the various parties' submissions. After a sketch of the development of the ship design, Chapters I and II review the most distinctive features, namely the hull, the bow, and the propulsion system with its transmission. The designers' rationale and claims for these are noted, and also the interveners' observation that there was comparatively little precedent to judge the design by, and that APP's continual refinements made it difficult to assess. Chapters III and IV outline the proposed storage systems for both the LNG cargo and the auxiliary diesel fuel, with the accompanying safety features. Chapter V summarizes discussions about the ships' ability to execute the expected manoeuvres when making port and docking, both at the proposed LNG plant at Bridport on Melville Island and at delivery ports. Chapter VI reviews operations, both when loading and at sea, and considers especially the likelihood of spilling either LNG or oil, the measures APP proposed for preventing or dealing with such accidents, and the likely consequence for wildlife and the natural environment. Chapter VII discusses the proposed navigating-aids, and some expected limitations on their use in Arctic latitudes. Chapter VIII describes the tankers' proposed normal route for delivery at an eastern Canadian port, and expected deviations, and also some concerns voiced by spokesmen for the populations that might be affected. Chapter IX deals with how the ships' continual passage might affect the ice regime and traditional Inuit hunting. Chapters X and XI discuss how far one can legitimately extrapolate to the actual tankers' behaviour from scale-model testing and from smaller vessels now operating in the Arctic. The author has sought not to construct an argument either for or against APP's proposal, but to present the testimony in an ordered framework and let it speak for itself. In fairness, however, it should be borne in mind that the Board eventually adjourned the hearing because APP had substantially changed its export proposal. Had the hearing been completed, there should have been further evidence about the ships; in particular, the issue of how much noise they would make, and how that might affect wildlife, would have been explored more thoroughly. Evidence is normally cited by the name of the witness and the volume and page numbers of the transcript; but within a paragraph or topic these are not needlessly repeated. In quoted testimony the wording follows the transcript exactly, except for the correction of a very few obvious errors. The author has, however, considered himself entitled to use correct and consistent spelling throughout, and to revise punctuation in the interest of clarity, since those features of the record stem not from the witnesses but from the court reporters"--ASTIS[online] database.
