maritime transport

As one of the most popular means of trade in the world, shipping by sea has always been subject to maritime hazards. Thus, the implicit commitment of a ship lease contract is that the transport operator provides a seaworthy ship. There is, however, no specific definition of the legal nature of this obligation in most conventions or international laws, and it is only in this regard that the statement of seaworthiness is cited as an implied obligation. Having been written in the descriptive-analytical method, this study attempts to explain the legal nature of this obligation, its position among absolutes or relatives, primaries or subsidiaries, implicit fundamentals or customs, its compliance with the conditions of article 234, the burden of proving seaworthiness, and the lack of performance guarantees caused by its absence. According to the results of the study, a transport operator is under a relative obligation to provide a seaworthy vessel. The existence of this obligation can be mentioned both as a main condition and a secondary condition, and if there is no specification in the contract, it is referred to as a customary implied obligation. Additionally, the condition of seaworthiness would be close to the verb condition in accordance with Article 234 of the Civil Code of Iran. For a claimant (the owner of the goods) to prove a lack of seaworthiness, they only need to provide evidence that the loss has occurred. For the sea transport operator to be relieved of responsibility, s/he must prove that s/he took the necessary precautions at the start of the voyage. The owner, otherwise, is responsible for compensating the victim for the damages caused by the violation of unseaworthiness by restoring the previous situation by providing the property and if an excuse is provided, by supplying a substitute.

Ships have always been considered and used as one of the important factors facilitating transportation and trade between countries. For this reason, maritime transport and its related industries are expanding more than before, and the diversity and equipment that can be used on ships is increasing. Nowadays, a lot of carbon is emitted by the shipping industry. It is expected that with the increase in world trade, carbon production will grow more than before. For this reason, the International Maritime Organization and the United Nations reviewed several regulations designed to reduce carbon emissions. These regulations should be applied to market actions business plans, etc. This research, which is a descriptive-analytical method, has tried to answer the basic question, what is the approach of international law regarding the ability of carbon control regulations to affect the shipping industry? The approach of this research shows that from the point of view of international law, carbon control regulations significantly affect the shipping industry.

Nowadays, along with the expansion of the era of globalization, the prosperity of trade, and internationalization, countries pay great attention to customs affairs to facilitate commercial issues. In this regard, they have tried to establish the security of this important process by involving the Navy. Therefore, the present research is trying to investigate the prospect of customs cooperation with the navy forces in facilitating maritime transport trade and developing international trade. From this point of view, following the expansion of the conceptual space of the subject, the role of the navy forces in facilitating maritime transport trade and the development of international trade will be investigated. According to the subject documents presented in this research, the research method is descriptive-analytical and the process of collecting information in this research is library. The findings of this article indicate that "the relationship between customs cooperation with the navy forces is an interactive and mutual one, in a way that customs and commercial activities can create conditions in which the navy forces benefit and by establishing maritime and commercial security, navy forces can provide the necessary ground for facilitating maritime transport trade and the development of international trade.
