Definition Of

Many tools handle with the calculation of compartment definition, hydrostatics, intact and damage stability and power prediction, but these calculations are separated from the rest of ship CAD/CAM tools. Ship designers need to work closely with the shipyards, in a complex and distributed environment making necessary to have suitable tools at early design stages to ensure profitable projects. Naval architecture is handled in FORAN with a revolutionary approach, where integration and advanced features are the relevant characteristics in a single and complete set of applications that are used in conjunction to other disciplines, from concept design to operation. This new approach groups the former modules for naval architecture available in FORAN from many years, is intuitive and user-friendly. The information is stored in a database instead of a wide set of files. As regards this feature, there are two different alternatives depending on the scope of the project. If the ship designer wants to calculate only naval architecture calculations, the solutions is based on a SQLITE database suitable for a standalone application. This approach benefits a ship design office, in the study of different design alternatives very quickly but having a complete control of them. The other option is integrating the Naval Architecture with the rest of FORAN design disciplines, in a single database based in Oracle. In this case, the great benefit comes from the single truth of data from concept design to operation, which ensures dramatically the reduction of errors and re-work. After the definition of compartments in 3D, by using a very fast application, the module guides the user through the naval architecture calculations with a tree of elements very intuitive, with powerful key algorithms and with a solid representation of spaces. The definition of the necessary entities to make any kind of calculation is very fast. For the intact stability a set of standard stability criteria is provided. It is based in a quick definition of loading conditions, initial situations, flooding conditions and compartment subdivisions. And for the evaluation of the damage stability a set of standard stability criteria are also provided, following deterministic and probabilistic approaches. With these tools any naval architect is able to make very fast all the necessary studies to assure the stability regulations are complied with.

The Stability

Determining the elements of stability of a vessel is basic to the profession of naval architecture. It is therefore disconcerting to discover that there is actually little in textbooks on how to determine whether the stability in a particular vessel is sufficient. On further reflection, one recognizes this as the consequence of understanding the response of the vessel but not understanding the forces which the sea may apply. This deficiency of criteria was recognized at the 1960 Convention for Safety of Life at Sea. The Convention included in the recommendations (Recommendation 7, SOLAS 1960) that the Intergovernmental Maritime Consultative Organization (IMCO) should subsequently undertake studies relative to the requirements for intact stability.

AbstractIt was proved in Forti and Schwaiger (C R Math Acad Sci Soc R Can 11(6):215–220, 1989), Schwaiger (Aequ Math 35:120–121, 1988) and with different methods in Schwaiger (Developments in functional equations and related topics. Selected papers based on the presentations at the 16th international conference on functional equations and inequalities, ICFEI, Bȩdlewo, Poland, May 17–23, 2015, Springer, Cham, pp 275–295, 2017) that under the assumption that every function defined on suitable abelian semigroups with values in a normed space such that the norm of its Cauchy difference is bounded by a constant (function) is close to some additive function, i.e., the norm of the difference between the given function and that additive function is also bounded by a constant, the normed space must necessarily be complete. By Schwaiger (Ann Math Sil 34:151–163, 2020) this is also true in the non-archimedean case. Here we discuss the situation when the bound is a suitable non-constant function.

Heeling Moment

A mathematical formulation of a computer-based method to evaluate the intact stability of floating structures is presented. The technique depends on describing the surface of the structure in terms of many small finite elements, which allows the analysis of complicated hull geometry, determining the hydrostatic pressure on each element for a known heel angle, and integrating the pressure forces to find the magnitude, direction, and line of action of the buoyant force. This will result in the correct location of the metacenter for small, as well as large, angles of heel. For structures of variable cross section, the position of the heeled vessel in equilibrium is defined such that the weight is balanced by the buoyant force, and only a pure righting moment associated with the heeling angle is evaluated. Formulation for the wind heeling moment is also presented. Assessment of the stability of the vessel is made from the righting and heeling moment curves in light of regulatory body rules.

Vessel Stability

It is well known that stability is the most important safety requirement for ships. One should have some information on ship stability at the preliminary design stage in order to reduce risk. Initial stability of ships is an important criterion and can be closely evaluated in terms of form parameters and vertical center of gravity. In this study, using some sample ship data, approximate formulations are derived by means of regression analysis for the calculations expressed in terms of ship preliminary design parameters that can easily provide approximate GM calculations. Thus designers can be provided with ship stability at the preliminary design stage, and also a set of appropriate design parameters for improving vessel stability can easily be determined.

North Natuna Sea is become a concern, at the end of 2019 to February 2020 this area was illegally entered by Chinese fishing vessels who wanted to fishing, this vessel was escorted by the Chinese Coast Guard. This escort is in order to protect their fishing vessels from the pursuit of Indonesian patrol vessels. According to the them that they did not violate Indonesian territory, they said that the North Natuna Sea still belongs to Chinese territory. In the perspective of the international relations what is done by China can disrupt the stability of regional security. This research is a qualitative descriptive with secondary data collection. The formulation of the research question is what kind of diplomacy is being carried out by Indonesia towards China in the North Natuna Sea. The purpose of this research is to find the right diplomacy concept in dealing with the China in the North Natuna Sea.
