This paper presents, for the first time, the application of the limited nonlinear energy sinks (L-NESs) and cells to achieve vibration suppression of floating raft isolation systems. In comparison to a traditional NES, L-NES increases the constraint on the NES vibrator by introducing piecewise stiffness. In addition, L-NES cells can not only effectively suppress the vibration of the floating raft system, but also display high practicability and flexible versatility by changing the number of cells. In this paper, a mechanical model of the floating raft isolation system with four degrees of freedom is established. The installation mode of the floating raft system is analyzed. Analysis of the parameters of the damping system with the NESs and L-NESs is carried out respectively. Hyperbolic tangent function is used to fit non-smooth models. Then the harmonic balance method (HBM) is applied as an analytical method to obtain the approximate solution of the system, and the accuracy is verified. The damping effects of the vibration reduction systems coupled with the traditional NESs and L-NESs are compared. Meanwhile, a vibration reduction model of the floating raft system with the L-NES cells is established. The influence of the number of the L-NES cells on the vibration suppression efficiency of the system for the first three modes is analyzed. The results show that the vibration suppression effective of the floating raft can be extremely improved and the problem of achieving damping for the low frequency band can be solved by the proposed L-NESs and cells. In a word, the research in this paper provides a novel and effective idea for the vibration control of floating raft systems.</p></div>","PeriodicalId":49879,"journal":{"name":"Marine Structures","volume":"96 ","pages":"Article 103629"},"PeriodicalIF":3.9,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140347151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to accurately predict the upheaval buckling behaviour of subsea pipelines, the axial pipe-soil resistance should be considered more precisely, rather than traditionally treated as rigid-plastic in prior analytical researches on pipeline upheaval buckling. Consequently, this study integrates a bi-linear axial pipe-soil resistance model into the mathematical framework of upheaval buckling. This mathematical model incorporates the von-Kármán type of geometrical nonlinearity and the Euler-Bernoulli beam theory. The research examines typical upheaval buckling behaviour and investigates the influence of axial mobilization distance and ultimate resistance on pipeline upheaval buckling behaviour. The results reveal that incorporating bi-linear axial pipe-soil resistance, in contrast to rigid-plastic resistance, leads the pipeline more susceptible to buckling. Displacement amplitudes increase with the axial mobilization distance during the post-buckling stage. Notably, a larger axial mobilization distance exerts a stronger influence on pipeline buckling. Moreover, the critical buckling temperature exhibits an almost linear negative correlation with axial mobilization distance and a positive correlation with axial ultimate resistance. Additionally, greater axial ultimate resistance magnifies the impact of axial mobilization distance. Therefore, in pipeline buckling design, it is advisable to consider a more sophisticated axial pipe-soil model to accurately account for these complexities.</p></div>","PeriodicalId":49879,"journal":{"name":"Marine Structures","volume":"96 ","pages":"Article 103628"},"PeriodicalIF":3.9,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140332823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consisting of the lowering of the equipment by using a cable connected to a crane located on a support vessel, this method is usually more straightforward than others. However, the vertical stiffness of the system depends on the cable's length, meaning that the natural frequency of vertical motions will vary along the lowering of the equipment. At some water depths, the natural frequency will be close to the typical wave frequency of the region, which will lead to a dynamic amplification of these motions, which can lead to the slackness of the cable, that is, there will be zero tension on the cable. The lack of stiffness due to the slackness means that the equipment's submerged weight will be responsible for bringing the equipment downwards, leading subsequently to higher tension peaks usually known as snap loads. The current recommendation by the classification societies is to avoid installing under environmental conditions when slackness occurs. However, based on the understanding of the nonlinear anatomy when the cable is slack, the present work shows that it would be possible to increase the operation window.</p></div>","PeriodicalId":49879,"journal":{"name":"Marine Structures","volume":"96 ","pages":"Article 103626"},"PeriodicalIF":3.9,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140309950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By comparing the NIAH equivalent results with the fine finite element model results, it was found that the relative error was within 3.00 % and the calculation cost was reduced by 40 times. Compared with the experimental results, the error of NIAH equivalent results was also less than 6.00 %, which verified the accuracy and high efficiency of the NIAH equivalent method.

Predicting welding-induced deformation is a critical task in design and control management at a shipyard, and much research has focused on the inherent strain method among possible efficient numerical methods. However, determining the inherent strain requires the synchronisation of all strain terms as a function of time and welding uncertainty because the welding position depends on the human worker. The present study thus derives time-dependent terms for inherent strain of the overall welding process and includes the welding position and cooling method in the function of the heat transfer coefficient. The inherent strain is derived through the detailed analysis of the overall welding process in terms of the application and utilisation, and it is simulated and reviewed for the erection of the hull block of a container ship and an LNG carrier.

This study provides a comprehensive evaluation of plant biomass-based composites (PBCs) within the maritime sector, focusing on their composition, treatment methods, properties, and diverse applications. It highlights the extensive use of various plant biomass components, such as stems, leaves, seeds, grass, and wood, as effective fillers for PBCs.

Polymer-based matrices are the most commonly chosen for PBC synthesis, although metals and ceramics are also utilized. The study examines the mechanical, chemical, water absorption, thermal, electrical, and morphological properties of PBCs relevant to the maritime industry. Applications of these composites are broad and encompass the production of boats, hulls, decks, canoes, surfboards, shipping ropes, paddles, and more. The adaptability and versatility of PBCs across these applications hold the potential to enhance structural integrity, reduce maintenance costs, and improve environmental performance in the maritime industry. This research contributes to a better understanding of plant biomass-based composites' potential in the maritime sector, addressing global concerns related to climate change and resource conservation.
