This paper is about a case on the arbitration of disputes between the parties of charter party. 'B' vessel owner on the original charter party first made a charter party with 'L' cargo owner on the original charter party. Then, 'B' entered into another charter party with 'D' vessel owner, who will actually take charge of carriage of the cargoes which is described on the original charter party. Therefore, 'B' is a carrier of cargoes of 'L' and 'D' is a carrier of cargoes of 'B', according to the contracts. The cargoes of 'B' is cargoes of 'L', by nature. In these circumstances, damages to the cargoes occurred in the transit by the vessel of 'D'. Who should take the responsibility for the damage of cargoes? Who must be liable for those, 'B' or 'D'？. According to the original charter party, 'L' signed 'as Charterers' and 'B' was the counterpart of 'L'. But 'B' signed as 'for and on behalf of 'B',' without 'as Owners'. Tribunal of arbitration award that 'B' should take the responsibility for the damage to the cargoes, because 'B' is the vessel owner. Although 'B' is a contract carrier, 'B' must bear the liability of transport of the cargoes. The counterpart of charterer, 'L' is 'B' who is presumed to be the vessel owner by the original charter party. 'D', actual carrier is not the privy of 'L', cargo owner. This case teach us that signature on the contract is the matter of great importance.

The external reactor vessel cooling (ERVC) is well known strategy to mitigate a severe accident at which nuclear fuel inside the reactor vessel is molten. In order to compare the heat removal capacity of ERVC between the nuclear reactor designs quantitatively, numerical method is often used. However, the study for ERVC using computational fluid dynamics (CFD) is still quite scarce. As a validation study on the numerical prediction for ERVC using CFD, the subcooled boiling flow and natural circulation of coolant at the ULPU-V experiment was simulated. The commercially available CFD software ANSYS-CFX was used. Shear stress transport (SST) model and RPI model were used for turbulence closure and wall-boiling, respectively. The averaged flow velocities in the downcomer and the baffle entry under the reactor vessel lower plenum are in good agreement with the available experimental data and recent computational results. Steam generated from the heated wall condenses rapidly and coolant flows maintains single-phase flow until coolant boils again by flashing process due to the decrease of saturation temperature induced by higher elevation. Hence, the flow rate of coolant natural circulation does not vary significantly with the change of heat flux applied at the reactor vessel, which is also consistent with the previous literatures.

ISO 21029 cryogenic vessel is used to transport cryogenic fluids. High-manganese steel (High-Mn steel) is widely regarded as suitable for use at cryogenic temperatures. The conventional way of manufacturing an ellipsoidal vessel head involves incremental stretching, followed by a spinning process. In this study, an alternative method for forming an ellipsoidal vessel head was proposed. Finite element analysis (FEA) was used to theoretically examine the strain evolution during a multi-stage forming process, which involved progressive stretching, deep drawing, and spinning of High-Mn steel. The distribution of effective strain and strain components were analyzed at different regions of the formed part. The FEA results revealed that only normal strains were evident in the dished region of the vessel head due to the stretching process. However, the flange region experienced complex strain evolution during the subsequent deep drawing and spinning process.

Purpose - This study analyses the excepted requirement and burden of proof of the carrier due to unseaworthiness through comparison between the marine transport contract and marine insurance contract. Design/methodology - This study uses the legal analytical normative approach. The juridical approach involves reviewing and examining theories, concepts, legal doctrines and legislation that are related to the problems. In this study a literature analysis using academic literature and internet data is conducted. Findings - The burden of proof in case of seaworthiness should be based on presumed fault, not proved fault. The burden of proving unseaworthiness/seaworthiness should shift to the carrier, and should be exercised before seeking the protections of the law or carriage contract. In other words, the insurer cannot escape coverage for unfitness of a vessel which arises while the vessel is at sea, which the assured could not have prevented in the exercise of due diligence. The insurer bears the burden of proving unseaworthiness. The warranty of seaworthiness is implied in hull, but not protection and indemnity policies. The 2015 Act repeals ss. 33(3) and 34 of MIA 1906. Otherwise the provisions of the MIA 1906 remain in force, including the definition of a promissory warranty and the recognition of implied warranties. There is less clarity about the position when the source of the loss occurs before the breach of warranty but the actual loss is suffered after the breach. Nonetheless, by s.10(2) of the 2015 Act the insurer appears not to be liable for any loss occurring after the breach of warranty and before there has been a remedy. Originality/value - When unseaworthiness is identified after the sailing of the vessel, mere acceptance of the ship does not mean the party waives any claims for damages or the right to terminate the contract, provided that failure to comply with the contractual obligations is of critical importance. The burden of proof with regards to loss of damage to a cargo caused by unseaworthiness is regulated by the applicable law. For instance, under the common law, if the cargo claimant alleges that the loss or damage has been caused by unseaworthiness, then he has the burden of proof to establish the followings: (i) that the vessel was unseaworthy at the beginning of the voyage; and that, (ii) that the loss or damage has been caused by such unseaworthiness. In other words, if the warranty of seaworthiness at the inception of the voyage is breached, the breach voids the policy if the ship owner had prior knowledge of the unseaworthy condition. By contrast, knowingly permitting the vessel to break ground in an unseaworthy condition denies liability only for loss or damage proximately caused by the unseaworthiness. Such a breach does not, therefore, void the entire policy, but only serves to exonerate the insurer for loss or damage proximately caused by the unseaworthy condition.

In this paper, a three-dimensional hydrogen absorption model is developed to precisely study hydrogen absorption reaction and resultant heat and mass transport phenomena in metal hydride hydrogen storage vessels. The 3D model is first experimentally validated against the temperature evolution data available in the literature. In addition to model validation, the detailed simulation results shows that at the initial absorption stage, the vessel temperature and H/M ratio distributions are uniform throughout the entire vessel, indicating that the hydrogen absorption is so efficient during the early hydriding process and thus local cooling effect is not influential. On the other hand, nonuniform distributions are predicted at the latter absorption stage, which is mainly due to different degrees of cooling between the vessel wall and core regions. This numerical study provides the fundamental understanding of detailed heat and mass transfer phenomena during hydrogen absorption process and further indicates that efficient design of storage vessel and cooling system is critical to achieve fast hydrogen charging and high hydrogen storage efficiency.

It is well-known that if a claim for damage [Note: Damage can be singular or plural] is made based on a breach of contract, calculating the existence and magnitude of certain profits to be deducted based on the damage can be problematic. In the case of a time charter party, even if the early redelivering vessel by the time charterers constitutes a breach of contract, it is still not an exception. In particular, interest in the shipping business seems to be relatively high in terms of how claims for damage by ship owners have been adjusted. In the case of the New Flamenco, there is a debate over whether or not to deduct the difference between the sale price immediately after redelivering the ship and the sale price upon expiration of the contract from the damage based on the breach of contract for the early time charter redelivery vessel. This paper focuses on this case since it appears to be of practical importance and has implications on how to calculate the amount of damage in the case of cancellation for early redelivery vessel in a time charter party.

The KN-12 transport cask has been designed to transport 12 PWR spent nuclear fuel assemblies and to comply with the regulatory requirements for a Type B(U) package. The containment boundary of the cask is defined by a cask body, a cask lid, lid bolts with nuts, O-ring seals and a bolted closure lid. The containment vessel for the cask consists of a forged thick-walled carbon steel cylindrical body with an integrally-welded carbon steel bottom and is closed by a lid made of stainless steel, which is fastened to the cask body by lid bolts with nuts and sealed by double elastomer O-rings. In the cask lid an opening is closed by a plug with an O-ring seal and covered by the bolted closure lid sealed with an O-ring. The cask must maintain a radioactivity release rate of not more than the regulatory limit for normal transport conditions and for hypothetical accident conditions, as required by the related regulations. The containment requirements of the cask are satisfied by maintaining a maximum air reference leak rate of $2.7{\times}10^{-4}ref.cm^3s^{-1}$ or a helium leak rate of $3.3{\times}10^{-4}cm^3s^{-1}$ for normal transport conditions and for hypothetical accident conditions.

As we know, D-terms which are constituted with DAF delivered the goods in a border place, DES delivered the goods on board a vessel at a vessel specified port on the buyer's side, DEQ delivered the goods on the quay on the buyer's side as the specified place, DDU and DDP delivered the good at the stipulated place at the agreed place or point, mean arrival contracts. DAF is designed mainly for railway carriage, DES and DEQ are designed mainly for vessel shipment, DDU and DDP are designed mainly for multimodal transportation. In spite of their original purpose of revision. They have in themselves many problems on notable points on application in practice. Therefore, in order to magnify their use, through revision of Incoterms, DAF is restricted to railway carriage, DES and DEQ are restricted to be used only for charter shipments. Particularly transport documents which seller should supply the buyer with under DDU and DDP are documents for ownership and possession rights to the goods loaded when executed in negotiable form like as CIF.
