  • The Design and Service Experience of the Polar Endeavour Class Tankers
    The Design and Service Experience of the Polar Endeavour Class Tankers Robert A. Levine1, (M) SNAME, (M) IMarEST, C.Eng., Manager Engineering Integration & Naval Architecture, ConocoPhillips Marine ABSTRACT The Polar Endeavour (Millennium) Class Tankers, represent the first U. S. flag crude oil carriers designed and built for the Alaskan Trade in compliance with the Oil Pollution Act of 1990 (OPA90). These vessels represent the start of a revolution in design for American crude carriers. Not only are they fitted with double hulls, which are deeper than required, but also they are fitted with twin independent engine rooms, and twin rudders. They are the first vessels to be classed R2- S+ and NIBS under the American Bureau of Shipping’s (ABS) Guidelines for Redundant Propulsion Systems and Navigation Integrated Bridge Systems. The vessels meet the requirements for Annex VI of MARPOL for air emissions, and are painted with tin free (TBT) anti-foul paints. This paper describes the design development process used and the unique and innovated design, which resulted. Three vessels have entered service in 2001, 2002 and 2003 and two are under construction for delivery in 2004 and 2005. 1 The opinions expressed in this paper are those of the author and do not reflect those of Polar Tankers Inc., ConocoPhillips Marine, ConocoPhillips Alaska or the ConocoPhillips Corporation. 1 ACRONYMS +A1E Compliance with ABS Rules for Self- KW Kilowatts Propelled Vessels & Equipment LAN Local Area Network (Computer) Standards LBP Length Between Perpendiculars

The maritime industry plays an increas- ingly important role in the changing world economy, and this new series offers an outlet for reviewing trends and developments over time as well as analysing how such changes are affecting trade, transport, the environ- ment and financial markets. Each title in the series will communicate key research findings, shaping new approaches to maritime economics. The core audience will be academic, as well as policymakers, regulators and international maritime authorities and organisations. Individual titles will often be theoretically informed but will always be firmly evidence- based, seeking to link theory to policy outcomes and changing practices.

Color profile: Disabled Composite Default screen Grubb: Merchant Shipping in a Chinese Blockade of Taiwan MERCHANT SHIPPING IN A CHINESE BLOCKADE OF TAIWAN Lieutenant Michael C. Grubb, U.S. Navy here is a substantial literature on the various methods and tactics the armed forces of the People’s Republic of China (PRC) could employ to enforce a T 1 naval blockade of Taiwan during a Taiwan Strait crisis. However, there has been very little assessment of how the qualities of today’s global maritime shipping industry might affect the effectiveness of a blockade. If China chose to imple- ment a blockade, would the global maritime industry continue to utilize Tai- wan’s ports and support its import/export trade in the face of Chinese threats? If international merchant shipping abandoned the Taiwan market, does the mari- time industry of the Republic of China have sufficient capacity to keep its supply lines filled on its own? This article attempts to answer these questions, making the case that the global maritime trade industry is not likely to support Taiwan’s seaborne trade in the face of a PRC blockade, leaving Taiwan’s merchant fleet to meet the is- land’s strategic resupply needs.
