The officer of the deck (OOD) of a US Navy ship is in charge of the safe and proper operation of the ship, and accountable to the commanding officer for every event that occurs during his or her OOD watch. This paper discusses the development of a prototype behavioral marker system to evaluate, and provide feedback on, the nontechnical (cognitive, social, and personal resource) skills of OODs. ...

Shipping and stevedoring industry is going to witness a massive increase in the amount of containers to be handled while land constraints become more critical. Offshore transfer operations hence offer a preferable solution to deal with the surge in cargos rather than to expand the port outwards. Recently, there has been increasing research interests on offshore crane automation. Suspended cargo...

Reduces weight of hull structures designed for a very large carrier plays an important role as the economic efficiency is the most significant aspect. It is known that the traditional allowable working stress approaches with high safety and reliability, it means that the hull structural weight is higher than the actual requirement in operation. Recently, the limit state approach has been widely...

Ship motion is an important influencing factor in passenger ship evacuation that affects the entire process by reducing individual’s walking speed. This study aims to quantify such effects berthing and sailing operations collecting experimental data support decisions. The utilized Dalian Maritime University’s training conduct human experiments influence of on passengers’ normal fast speeds. It ...

We consider the problem of controlling the vertical motion of a nonlinear model of a helicopter, while stabilizing the lateral and horizontal position and maintaining a constant attitude. The reference to be tracked is given by a sum of a constant and a fixed number of sinusoidal signals, and it is assumed not to be available to the controller. This represents a possible situation in which the ...

With the aim of extending the use of integrated variational principles on fluid and deckplate to the large deflection analysis of floating roofs, this paper investigates the significance of theflexural and membrane components in the formulations of the deck plate. Applying integratedvariational principles on deck plate and fluid facilitate the treatment of the compatibility ofdeformation betwee...

Greenwater (splashing of water on the deck) loading is a classical problem faced by designers ship-shaped vessels, which becomes even worse when vessel operates in harsh weather conditions for an extended period time. Installation breakwaters deck can play crucial role minimizing this impact. However, research design and optimization breakwater still its infancy, study aims at shedding further ...

The U.S. Liberty Ship Building Program in World War II set a record—a total of 2700 Liberty Ships were built in 6 years, in order to support the battle against Nazi-Germany. However, numerous vessels suffered sudden fracture, some of them being split in half. This paper demonstrates and investigation of the Liberty Ships failure and problems, which reveals that the failures are caused by a comb...

Here, liquid water path (LWP), cloud fraction, cloud top height, and cloud base height retrieved by a suite of A-train satellite instruments (the CPR aboard CloudSat, CALIOP aboard CALIPSO, and MODIS aboard Aqua) are compared to ship observations from research cruises made in 2001 and 2003–2007 into the stratus/stratocumulus deck over the southeast Pacific Ocean. It is found that CloudSat radar...

A helicopter deck is the main load-bearing component under emergency landing conditions for helicopters. However, it generally difficult to directly obtain load from measurements due high randomness of position. As design deck, very important its structural design. large value leads an overly conservative and affects control ship’s weight center gravity, while a small may lead lack security aff...
