  • Branch's Elements of Shipping/Alan E
    ‘I would strongly recommend this book to anyone who is interested in shipping or taking a course where shipping is an important element, for example, chartering and broking, maritime transport, exporting and importing, ship management, and international trade. Using an approach of simple analysis and pragmatism, the book provides clear explanations of the basic elements of ship operations and commercial, legal, economic, technical, managerial, logistical, and financial aspects of shipping.’ Dr Jiangang Fei, National Centre for Ports & Shipping, Australian Maritime College, University of Tasmania, Australia ‘Branch’s Elements of Shipping provides the reader with the best all-round examination of the many elements of the international shipping industry. This edition serves as a fitting tribute to Alan Branch and is an essential text for anyone with an interest in global shipping.’ David Adkins, Lecturer in International Procurement and Supply Chain Management, Plymouth Graduate School of Management, Plymouth University ‘Combining the traditional with the modern is as much a challenge as illuminating operations without getting lost in the fascination of the technical detail. This is particularly true for the world of shipping! Branch’s Elements of Shipping is an ongoing example for mastering these challenges. With its clear maritime focus it provides a very comprehensive knowledge base for relevant terms and details and it is a useful source of expertise for students and practitioners in the field.’ Günter Prockl, Associate Professor, Copenhagen Business School, Denmark This page intentionally left blank Branch’s Elements of Shipping Since it was first published in 1964, Elements of Shipping has become established as a market leader.

  • The IMO Number Explained
    A fact sheet from May 2017 Adam Baske The IMO Number Explained What is an IMO number? The International Maritime Organization (IMO) introduced its Ship Identification Number Scheme in 1987 to help prevent maritime fraud and enhance the security of merchant vessels. It is recognized by regional fisheries organizations and most governments and is considered the best available global identification system for ships. IHS Maritime & Trade, a company based in the U.K., administers the scheme on behalf of the IMO. The unique seven-digit vessel number the company issues to each vessel, preceded by the letters IMO, stays with it until it is scrapped and never changes, regardless of the ship’s owner, country of registration or name. The records based on the IMO number provide an independent audit trail for each vessel. The scheme was applied to fishing vessels in 2013, and the eligibility criteria were amended in 2016 to cover smaller and non-steel hull vessels. Why do fishing vessels need an IMO number? Illegal, unreported, and unregulated fishing worldwide accounts for up to 26 million metric tons of fish annually, worth up to $23.5 billion. IMO numbers are an essential tool in the fight against illegal fishing because they help to improve monitoring, control, surveillance and enforcement of fishing operations. They: • Allow flag States to accurately manage vessels under their authority. • Give national authorities information to help them police their waters more effectively. • Bring clarity and consistency to Regional Fisheries Management Organization (RFMO) records, helping governments determine whether vessels are authorized to fish in their waters.

  • Millennium Class Tanker Structural Design – from Owner Experience to Shipyard Launching Ways
    Millennium Class Tanker Structural Design – From Owner Experience to Shipyard Launching Ways James Read1, Arne Stenseng2, Rod Hulla3 and Darold Poulin4 ABSTRACT Three 125,000 DWT double hull tankers are currently under construction for ARCO Marine, Inc. at Litton Avondale Industries in New Orleans, LA. These Millennium Class tankers are being built to transport crude oil from Valdez, AK to Cherry Point, WA. The design satisfies the requirements of OPA 90 and incorporates a unique structural design philosophy intended to enhance the structural performance of the vessel. This paper will illustrate how the Owner’s experience with previous vessels in Gulf of Alaska trade is reflected in the structural design of the new ships. The human elements of safety, inspection and maintenance are discussed and the influence of these factors on the structural arrangement is highlighted. In concert with these human factors are structural design improvements that have been implemented to specifically address fatigue and stress cracking with the intent of reducing repair requirements. These topics are presented in a discussion that follows the structural design from concept, through design and analysis and into the construction of the vessels. Lessons learned throughout the process are presented. 1 ARCO Marine, Inc., Long Beach, California 2 MCA Engineers, Inc., Costa Mesa, California 3 John J.

  • 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
