Section July 7, 2005 Presentation of the Best Diploma Theses bt Students of NTUA and Award to the Bwat of Them On July 7, 2005 the sixth technical meeting of the Greek Section for 2005 took place at the auditorium and reception facilities of Kristen Navigation Inc, which has kindly hosted the Greek Section meetings since the section was started in 2002. The meeting was attended by about forty members and non-members, including Academic staff and students from the School of Naval Architecture and Marine Engineering (NAME) of the National Technical University of Athens (NTUA). The School of NAME selected the following four diploma theses from the summer semester for presentation at this Section meeting: 1.
Hatzinikolaou Stefanos, “Ship Operational Pollution in Greece”
(advisor Prof. H. Psaraftis). Following a decision by the Executive Committee of the Greek Section, an award committee was formed which consisted of the Section Chairman, Assoc. Prof. G. Grigoropoulos, the Regional Vice President and Vice-Chairman of the Section Mr. Petros Lalangas and the Academic staff present from NTUA, all members of SNAME (Prof. A. Papanikolaou, Chairman of the School of NAME/NTUA, Prof. G. Tzabiras, Asst. Prof. D. Lyridis and Asst. Prof. L. Kaiktsis).
Immediately after the presentations the award committee met and after pointing out the high level and quality of all presentations, it selected the thesis of Mr Elias Rizos for both the quality of its content and presentation, and therefore received the best thesis award. The award was accompanied by a Certificate and a prize of 500 euros. Furthermore, to all presenters a free SNAME student subscription was offered. After the meeting hors d’oeuvres, soft drinks and beer were offered to all the participants.

Section July 26, 2005 Tugs and Barges, “It’s What’s Up Front That Counts”
The Gulf Section of the Society of Naval Architects & Marine Engineers was honored to have Sal Guarino present his paper on Tugs and Barges, “It’s What’s Up Front That Counts” during our July 26th, 2005 meeting. Approximately 50 honored SNAME members and their distinguished guests gathered at the beautiful Diamond Head Country Club to listen to the legendary tug and barge designer. Mr. Guarino’s presentation provided a brief overview of the history and development of towing with the barge being towed behind and its current configuration “up front”. This included the history of towboats in the U.S. and abroad, including those that steamed the mighty Mississippi in the 1800’s. His history overview spanned over 150 years to his firms past and present experiences with Articulated Tug Barges (ATB). Mr. Guarino focused half of his discussion on aspects of ATB tug design. Currently Articulated Tug Barges are very popular in the 50,000 to 110,000 range; though recently designs have been proposed for barges over 300,000 barrels in charter service, and 500,000 barrels acting as an ATB shuttle tanker. Many of the advancements in the ATB market are the installation of pinning connection systems, the usage of heavy fuel oil engines for propulsion, and more comfortable accommodations for crews. Sal’s firm, Guarino & Cox LLC is currently finishing engineering work with a shipyard building a 150,000-barrel ATB for a US Client. This project is powered by Wartsila heavy-fuel engine, which departures from standard practice by having a higher initial capital cost, but are believed to result in significant life cycle cost savings. Sal Guarino included a brief description of the double skin ocean service oil barge designs market and how it’s effecting the life cycle and phase out of existing single skin oil barge. His discussion included some statistics on the current single skin oil barge conversions to meet the current OPA ’90 regulations. In closing, Mr. Guarino added that tugs and barges have come a long way. He finds that tugs are falling deeper into the barge notch, tugs are becoming more powerful, and the barges are becoming larger while optimized for speed. Ocean and Inland tug-barge traffic have proven to be integral components in the U.S transportation sector as well as the shipbuilding and designing industry of tomorrow. The versatility of the articulated tug-barge will hopefully keep the Jones Act liquid-bulk cargo market alive for years to come. The Gulf Section Officers would like to give special thanks to Sal Guarino, and all the section members for spending the evening with us in Diamond Head, Mississippi. Elections were held during the January elections, the 2005-2006 officers are: Chairman
