With the increasing development of the shipbuilding industry in the global arena, the need for the presence of foreign companies in this field and especially investment in it was felt more than ever. The benefits of the presence of foreigners and the existence of sanctions against Iran gave special importance to how the contract was concluded. However, considering that the contract is considered an indefinite contract and its limits and limits are agreed upon between the parties according to the freedom of will (Article 10 of the Civil Code of Iran). In this research, we considered the conditions of the representative and the duties of its parties against the third party to be important and examined. The authors have tried to process the subject by using a descriptive-analytical research method and library data collection method. What was obtained from this research is the need to pay attention to the representative's behavior and the limits of authority granted to the representative by the principle. Considering all the aspects mentioned in this research, a relatively reliable contract can be concluded.

After dividing the sea as areas under the sovereignty and sovereign rights of the coastal states and High seas in  the 1982 Convention on the Law of the Sea, and as a result of the possibility of detaining some foreign vessels violating the rules governing these areas, this convention also has rules regarding the prompt release of these vessels and how Its implementation has been stated in the judicial proceedings of the Coastal Government. In this regard, cases have been introduced in the International Tribunal of Law of the Sea, whose analysis can be considered as a judicial procedure and a secondary source of the law of the sea in development. In this article, in addition to the analysis and review of the judicial procedure and the 1982 Convention on the Law of the Sea, Iran's internal rules have also been reviewed in this regard. This research seeks to answer the question, in addition to clarifying the various aspects of immediate release, what are the criteria for prompt release, and what are appropriate and reasonable bonds? The research method is descriptive and analytical, and materials have been prepared based on library and documentary studies.

The naval conflict has undergone many changes due to environmental factors and various tools, as well as the increasing growth and development of marine technologies, aligned with the inclusion of new tools and methods in naval conflict and electronic warfare at sea. The procedure taken by countries indicates the acceptance of electronic warfare as one of the methods and tools of agreed warfare. However, from the perspective of international humanitarian law, the use of electronic warfare tools and methods is challenging, and international treaty law lacks a legal rule regarding this method of warfare. Indeed, the only guideline that has sought to regulate electronic warfare is the Air and Missile Warfare Directive, which imposes no legal requirements on governments. So the question we are going to answer in this brief is that, can humanitarian law be applied to electronic warfare? The purpose of this study is to explain and investigate the various dimensions of naval electronic warfare from the perspective of international humanitarian law, and proving that international humanitarian law can be applied to the methods and tools of electronic warfare at sea. The research method selected for the present paper is an analytical-explanatory method and the data collection method used is the library research method.

The increase in sea traffic with commercial ships, warships, and submarines, followed by the spread of pollution of the seas in the last century, has not only led to the threat and destruction of vital resources and marine habitats but also a source of tension and conflict between units and actors. It has provided political and can be a threat to the world community. Despite Legal requirements, pollution in the seas is increasing. The sovereignty-oriented nature of marine pollution legal requirements is one of the most important reasons for governments' reluctance to implement regulations related to marine pollution because the development of rules in this field, as well as the implementation of regulations related to marine pollution, are still within the scope of governments' satisfaction. Considering the importance of protecting the marine environment, this research deals with the scope of the coastal government's competence to deal with marine pollution using a descriptive-analytical method and with the help of library data and international documents. The findings of the research show that although the instrumental use of the concept of national sovereignty has created the basis for the pollution of the seas, Recent developments in the field of international law of the sea, such as the drafting of Article 3 of the Convention on Interference in the High Seas and paragraph one of Article 218 of the Convention on the Law of the Sea, indicate the extraterritorial expansion of the jurisdiction of coastal states to deal with marine pollution, although in a limited way.

Integrating application systems based in organizations creates coordination and interaction between people and organizational units and hardware, software, and database infrastructures. This optimal solution integration results in achieving process maturity and creating suitable conditions for making strategic decisions at management levels to improve organizational performance. Therefore, this study aimed to develop a native executive method for integrating organizational application systems at the management level following the characteristics of Iranian government organizations and their execution in a marine organization platform as a case study. V method was used as a methodology in the execution algorithm for integrating organizational application systems. The effectiveness of the proposed method was proved through a case study and its execution in the real world in the framework of a government organization. The executive method explained for the integration of application systems in the field of defense management was implemented as a case study. This method became native to the marine industry and is suitable for use at the management levels of marine organizations. The advantages and achievements of using this executive method in a case study are 1) Improving the flow of data and information, 2) Increasing the ability to interpret data and information, 3) Reducing the costs of implementing, using, developing, and maintaining databases and organizational application systems, 4) Increasing flexibility and productivity of business processes, and 5) Integration and automation of processes is desirable.

The South China Sea, along with the Korean Peninsula and the Taiwan Strait, is described as one of the three hotspots in East Asia because of its potential for conflict of interest and threat to peace and security. Therefore, the issue of its borders is of international importance. As a quasi-closed sea, it is home to numerous small islands and cliffs, as well as abundant living and non-marine reserves, as well as providing key maritime routes for commercial navigation. For these reasons, the sea has become the target of conflict between coastal countries and its neighbors. In this sea, the main issues in dispute are: 1- Border disputes over the determination of the lines of origin, the boundaries of the territorial seas and also the exclusive economic zone2. Territorial disputes over several islands, including the Paracel and Spratly archipelagos. Because of its superior power, as well as some unproven historical claims, China sets the nine-dash as the final line of its sovereignty, some of which extend as far as the coastal sea. The United States and the countries bordering the South China Sea strongly oppose this, as well as China's historic claims. The littoral states of the South China Sea consider the historic claims and the nine-dash claimed by the Chinese government to be contrary to the laws of the UN Convention. The United States, as a trans-regional player, also provides diverse support to coastal countries. In this research, with a descriptive analytical approach and using new sources, the disputed issues between the claiming countries have been studied and the role of the United States in terms of geopolitical competition has been analyzed.

The carrier in sea transportation is obligated to proceed with the voyage on the contractual route. The violation may exempt the insurer from supporting the loss and damage to cargo after deviation from the route. Regarding the importance of marine insurance contract validity in international commerce, this question arises whether the ship deviation invalidates the insurance contract and exonerates the insurer to compensate. In the English marine insurance act 1906, the insurer is exempted from compensating for damages and the courts consider the claim regarding the circumstances governing the case. The lack of a marine insurance act in Iranian legislation requires us to consider the matter of the general rules in the insurance act 1937 that analyze performance guarantees such as invalidity and right of termination on the contract. If the additional insurance premium is not agreed upon in the contract, the right to terminate the contractual relationship is an approach that protects the insurer in different cases. Nowadays, because the insurance companies do not fully compensate for the damage, part of that is compensated by the P&I clubs. In fact, there is a kind of supplementary compensation covered after deviation. The mentioned question is analyzed with the descriptive-analytical method and library sources in this article. 

From ancient times, piracy has been known as an enemy of humanity and an international crime. One of the areas that has become the main center of piracy in recent years is the Gulf of Guinea . Due to the discovery and exploitation of rich oil resources, and the high traffic of oil tanker ships and other fishing and cargo ships, this area has been considered by pirates and has made maritime security confronted with a serious threat. According to statistics, between 2009 and 2021, about 265 cases of pirate attacks on ships have been reported in this region, which is regarded as the highest figure in the whole. The main question is, what are the effective causes of the creation and expansion of piracy in the Gulf of Guinea? And what solutions are there to confront this phenomenon? In response to this question, the hypothesis is that regional differences and the political, economic and social situations of the coastal states are the most important reasons in the spread of piracy in this region, and regional and extra-regional measures to confront it are inevitable. But the weakness of the countries in the region in securing the sea fleet, widespread unemployment, conflicts between countries in delimiting the borders of the sea, have made it difficult to fight against piracy in this region. The findings of this research show that identifying and eliminating the various factors involved in the occurrence of this crime depends on efforts beyond diplomatic cooperation. The lack of similarity between criminal measures and especially the obvious difference in the political conditions of the countries of the region compared to other regions facing the phenomenon of piracy, such as the case of the Gulf of Aden, makes it impossible to apply a similar solution to the Gulf of Guinea.
