Product Information

One deuce," Emma—who's in graduate school and until recently worked part-time as a restaurant hostess—corrects me. A waiter comes over and says he's setting a table for us. We invite Frank to join us, since it's unclear whether he's eaten tonight, but he politely declines. He says he'll come sit with us later on, but he won't eat. She doesn't eat shellfish or meat," I say, louder this time. "But I eat everything and I want to try what you're known for." Finding the forces on the ship when it is restrained from motion and subjected to regular waves. The forces acting on the body are:

However, OrcaFlex can accept RAO data using a wide range of different conventions, so you can input your RAO data in its original form and simply tell OrcaFlex what conventions apply to those data.In the field of ship design and design of other floating structures, a response amplitude operator ( RAO) is an engineering statistic, or set of such statistics, that are used to determine the likely behavior of a ship when operating at sea. Known by the acronym of RAO, response amplitude operators are usually obtained from models of proposed ship designs tested in a model basin, or from running specialized CFD computer programs, often both. RAOs are usually calculated for all ship motions and for all wave headings. In the above, "Ship" must be interpreted widely to also include other forms of floating structures. The obvious problem in the above method is the neglection of viscous forces which contribute heavily in modes of motion like surge and roll. The Diffraction forces, which are pressures that occur due to the disturbances in the water because of a body being present. And this is Tony Tantillo. He's on CBS every day, cooking with his daughter," Frank says, introducing us to another friend who's come up to the bar. "Listen, Tantillo. I gotta tell you. You're too good-looking. You're too handsome." As well as displacement RAOs, which directly specify the motion of a vessel in waves, OrcaFlex can apply wave load RAOs, which represent instead the load (force and moment) on a vessel due to waves. In this case, the amplitude represents the magnitude of the force (in the surge, sway or heave direction) or moment (in the roll, pitch or yaw direction); the meaning of the phase remains unchanged. Example:

Good guy. I like him. He's okay. I could sit with Peter King and say what I like and what I don't like. I'm a political junkie," Frank says. There's a letter from President George H.W. Bush on the wall. Frank doesn't discriminate. RAOs are effectively transfer functions used to determine the effect that a sea state will have upon the motion of a ship through the water, and therefore, for example, whether or not (in the case of cargo vessels) the addition of cargo to the vessel will require measures to be taken to improve stability and prevent the cargo from shifting within the vessel. Generation of extensive RAOs at the design phase allows shipbuilders to determine the modifications to a design that may be required for safety reasons (i.e., to make the design robust and resistant to capsizing or sinking in highly adverse sea conditions) or to improve performance (e.g., improve top speed, fuel consumption, stability in rough seas). RAOs are computed in tandem with the generation of a hydrodynamic database, which is a model of the effects of water pressure upon the ship's hull under a wide variety of flow conditions. Together, the RAOs and hydrodynamic database provide (inasmuch as this is possible within modelling and engineering constraints) certain assurances about the behavior of a proposed ship design. They also allow the designer to dimension the ship or structure so it will hold up to the most extreme sea states it will likely be subjected to (based on sea state statistics).A surge RAO of 0.5 in a wave of height 4m (and hence wave amplitude 2m) means that the vessel surges to and fro -1m to +1m from its static position; a pitch RAO of 0.5° per metre in the same wave means that the vessel pitches from -1° to + 1°. The RAO is a transfer function that is only defined when the ship motions can be assumed to be linear. The above forces can then be assembled into an equation of motion: There's only one table for two in the restaurant. "And if you're willing to wait, I'll feed you at that deuce," Pellegrino says. Where x {\displaystyle x} is a rigid body motion such as heave, ω {\displaystyle \omega } is the oscillation frequency, M {\displaystyle M} is the structural mass and inertia A ( ω ) {\displaystyle A(\omega )} is the added mass (frequency dependent), B ( ω ) {\displaystyle B(\omega )} is the linear damping (frequency dependent), C {\displaystyle C} is the restoring force coefficient (stiffness matrix) and F ( ω ) {\displaystyle F(\omega )} is the harmonic excitation force proportional to the incoming wave ζ = ζ a e i ω t {\displaystyle \zeta =\zeta _{a}e The first thing I noticed when we walked in was how bright the place is. It may be the brightest fine-dining establishment I've ever been to. The second thing I noticed was all the Christmas decorations (a story I'd read said they stay up year-round). Every chair at every table was full and the bar was crowded. An older bespectacled man sat on a stool in the corner, surveying the room, and motioned to suggest we sit at the two stools open next to him.

RAOs can be obtained either from model tests or from diffraction analysis software. The data may be presented in tabular or graphical form: tables of numbers are better for our purposes since they can be imported directly into OrcaFlex (see importing hydrodynamic data).A surge force RAO of 300 kN/m in a wave of height 6m (and hence wave amplitude 3m) means that a vessel experiences a surge force varying harmonically between -900kN and +900kN over each wave cycle; a pitch moment RAO of 1e6 kN.m/m in the same wave means that the vessel experiences a moment about the y axis varying from -3e6 kN.m to +3e6 kN.m.
