...Colen Kennell This paper presents insight into the structure of TFfuel, the Transport Factor component related to the weight of fuel needed to meet a ship's endurance requirement. TFfuel is shown to be dependent on the required range and the specific fuel consumption rate of the machinery while...

...Jeom kee Paik Ships and offshore structures are frequently subject to various types of actions and action effects during service that may range from the routine to the extreme or accidental. The oceanic environmental phenomena to which such structures may be exposed include freak/rogue waves...

...Roy F. Mengot; Richard T. Woytowich RMS Titanic collided with an iceberg and sank on the morning of April 15, 1912. Testimony at hearings on both sides of the Atlantic included conflicting stories of the ship breaking in two or sinking whole. The discovery of the wreck in 1985 confirmed...

...Pengfei Liu; Mohammed Fakhrul Islam; J. Michael Doucet; Andrew Prior; Goujun Huang A design and optimization procedure developed and used for a propeller installed on a twin-semitunnel-hull ship navigating in very shallow and icy water under heavy load conditions is presented. The base propeller...

... method for two operational profiles—one typical for oil tanker and the other one modified in order to reflect differences between oil tanker and chemical tanker. The evaluation of the wave-induced load effects that occur during long-term operation of the ship in the seaway is carried out in accordance...

...Hendrik F. van Hemmen COMSEAPRINT Human System Integration (HSI) is used to analyze the effect of reduced crew sizes and increased crew workloads resulting from increased regulatory requirements on oceangoing commercial vessels (as defined as ships with crew between 10 and 30). Most...

...Ulf B. Karlsson This paper presents a conceptual deformable inner barrier design with the aim of improving the collision safety during a collision into the side of a ship by facilitation of a deep intrusion before penetration. Validation of the conceptual design was made using finite element...

...Ming-Chung Fang; Jiun-Han Ju In order to investigate the dynamic stability and safety for a ship towing system operated in waves, the present paper develops a nonlinear mathematical model, including seakeeping and maneuvering characteristics, to simulate dynamic behaviors of the towing system...

... with full scale measurements that are available for this ship. By combining the long term "rigid body" wave-bending moment with the effects of hydroelasticity, a suitable service factor is derived for a Great Lakes Bulk Carrier traveling from the Canadian Great Lakes to China via the Suez Canal. 1 4...

...William H. Buckley A major seakeeping workshop was held in 1975 that identified seakeeping deficiencies in our ships compared with those of our NATO allies. The workshop was intended to lead to corrective action with the help of the expertise of the attendees. Because of existing deficiencies...

...Pekka Ruponen; Jerzy Matusiak; Janne Luukkonen; Mikko Ilus The water in a swimming pool on the top deck of a large passenger ship can be excited to a resonant motion, even in a moderate sea state. The motion of the water in the pool is mainly caused by longitudinal acceleration, resulting from...

...Ulf B. Karlsson; Jonas W. Ringsberg; Erland Johnson; Mohammed Hoseini; Anders Ulfvarson The finite element (FE) method is suitable as a numerical tool in the numerical analysis of, for example, ship collision scenarios. It is feasible to simulate and compare different collision scenarios...

...Marcelo A. S. Neves; Vadim Belenky The paper gives a brief review of the papers presented at the Ninth International Conference on Stability of Ships and Ocean Vehicles that was held on September 25 to 29, 2006 in Rio de Janeiro, Brazil. The review covers the following stability-related subjects...

...Ulf Karlsson; Anders Ulfvarson The ship research project DESSO (Design for Survival Onboard) aims at improving the safety of RO/RO (roll-on/roll-off) ferries. The project was organized in the autumn of 2003 in order to use the research and development resources existing in Sweden, combined...

...Kayhan Gulez; Fuat Alarcin This paper presents the performance comparative results of the classic backpropagation algorithms (CBAs) and fast backpropagation algorithms (FBAs) of neural networks applied for the rudder roll stabilizer (RRS) systems. The rudder is used to keep stability of the ship...

...Sherif Farouk Badran; Ashraf O. Nassef; Sayed M. Metwalli One aim of naval architects is to design structures that are strong enough and capable of absorbing impact energy. Therefore, ship plates are stiffened using different stiffeners to withstand compressive and other loads resulting from loads...
