Ram, Wayne State University n the morning of July 24, 1915, hundreds of employees of the West- Oern Electric Company and their families boarded the passenger steamship Eastland for a day trip to Michigan City, Indiana. Built in 1903, this twin screw, steel hulled steamship was considered a fast boat on her regular run. Yet throughout her service life, her design revealed a series of problems with stability. Additionally, changes such as more lifeboats in the aftermath of the Titanic disaster, repositioning of engines, and alterations to her upper cabins, made these built-in issues far worse. These failings would come to a disastrous head at the dock on the Chicago River. With over 2,500 passengers aboard, the ship heeled back and forth as the chief engineer struggled to control the ship’s stability and failed. At 7:30 a.m., the Eastland heeled to port, coming to rest on the river bottom, trapping pas- sengers inside the hull and throwing many more into the river.

  • Potential for Terrorist Nuclear Attack Using Oil Tankers
    Order Code RS21997 December 7, 2004 CRS Report for Congress Received through the CRS Web Port and Maritime Security: Potential for Terrorist Nuclear Attack Using Oil Tankers Jonathan Medalia Specialist in National Defense Foreign Affairs, Defense, and Trade Division Summary While much attention has been focused on threats to maritime security posed by cargo container ships, terrorists could also attempt to use oil tankers to stage an attack. If they were able to place an atomic bomb in a tanker and detonate it in a U.S. port, they would cause massive destruction and might halt crude oil shipments worldwide for some time. Detecting a bomb in a tanker would be difficult. Congress may consider various options to address this threat. This report will be updated as needed. Introduction The terrorist attacks of September 11, 2001, heightened interest in port and maritime security.1 Much of this interest has focused on cargo container ships because of concern that terrorists could use containers to transport weapons into the United States, yet only a small fraction of the millions of cargo containers entering the country each year is inspected. Some observers fear that a container-borne atomic bomb detonated in a U.S. port could wreak economic as well as physical havoc. Robert Bonner, the head of Customs and Border Protection (CBP) within the Department of Homeland Security (DHS), has argued that such an attack would lead to a halt to container traffic worldwide for some time, bringing the world economy to its knees. Stephen Flynn, a retired Coast Guard commander and an expert on maritime security at the Council on Foreign Relations, holds a similar view.2 While container ships accounted for 30.5% of vessel calls to U.S.

  • Safe Harbor Worksheet
    Safe Harbor Worksheet Description: Why should we care about Harbors? Roughly 90% of the world's goods are transported by sea. The port of NY/NJ is the third busiest port in the U.S. and the 18th in the World. Without our ports, life as we know it would not exist, however they are often overlooked. As trade volume increases, so does the size of ships. When European explorers first visited the New York Harbor, they found an estuary with a natural depth of 17 feet. As colonies became established and trade flourished, shipping channels were needed to allow for bigger ships. By 1880, the main ship channel was dredged to a depth of 24 feet and by 1891 to a depth of 30 feet. In 1914 the Ambrose Channel became the main entrance to the port of New York and had a depth of 40 feet and 2,000 feet wide (ship design changes/technological advancements allowed for wider ships). During World War II the main channel was dredged to 45 feet deep to accommodate larger ships up to Panamax size (the largest size ship which could travel through the Panama Canal). Panamax (1916) New Panamax (2016) Tonnage: 52,500 DWT Tonnage: 120,000 DWT Length: 950 ft Length: 1,201 ft Beam: 106 ft Beam: 161 ft Height: 190 ft Height: 190 ft Draft: 39.5 ft Draft: 50 ft Capacity: 5,000 TEU Capacity: 13,000 TEU Eventually even the Panama Canal was not big enough. In 2016, an expanded Panama Canal opened to allow for significantly larger ships (see above).

  • FULL-SCALE MEASUREMENTS to ASSESS SQUAT and VERTICAL MOTIONS in EXPOSED SHALLOW WATER by 1 2 3 Jeroen Verwilligen , Marc Mansuy , Marc Vantorre and Katrien Eloot4
    PIANC-World Congress Panama City, Panama 2018 FULL-SCALE MEASUREMENTS TO ASSESS SQUAT AND VERTICAL MOTIONS IN EXPOSED SHALLOW WATER by 1 2 3 Jeroen Verwilligen , Marc Mansuy , Marc Vantorre and Katrien Eloot4 ABSTRACT The paper presents the results of full scale measurements performed on seven cape-size bulk carriers sailing inbound to the port of Flushing/Vlissingen (the Netherlands). The voyages of this type of vessels correspond to small under keel clearances (to a minimal value of 16%) and exposed wave conditions (with a wave height up to 2.6 m). The main interest in this paper concerns the vertical motions experienced by the vessels and the identification and assessment of the major factors influencing these motions. As the vertical ship motions for bulk carriers operating in coastal waters are mainly related to seakeeping and squat, the unsteady and steady ship motions were analysed separately. The observations will be applied to validate a prediction tool for vertical ship motions, which is implemented by the Common Nautical Authority (Flanders / the Netherlands) to assess probabilistically the accessibility of deep-drafted vessels to the harbours along the river Scheldt. 1 INTRODUCTION The shipping traffic to the Belgian and Dutch ports located at the Western Scheldt estuary and the river Scheldt follows an access channel of which the depth is restricted. As a result, deep-drafted vessels cannot always sail 24 hours a day on the river Scheldt. The period in which these vessels may proceed inbound or outbound is called the tidal window. The Common Nautical Authority (CNA) calculates these tidal windows and gives permission for the vessels to proceed.
