Global Fatigue Analysis of the Mooring Systems for Offshore Floating Structures

The mooring system is essential for keeping the floating structures in place while performing marine applications under adverse weather conditions. However, mooring systems are subjected to fluctuating stresses due to structural details, material characteristics, and environmental factors resulting in fatigue damage. In addition, most studies only perform a local fatigue analysis focusing on the upper chain. However, a global fatigue assessment is necessary to determine the most critical fatigue location along the mooring line. A turret moored FPSO with nine mooring lines in a 400-meter water depth is utilised in this study. The metocean data is taken from the Gulf of Mexico. Three different mooring system designs have been established to analyse further the global fatigue analysis of the mooring lines induced by low frequency, wave frequency, and combined responses. Results reveal that the fatigue damage of the moorings is greatly influenced by wave frequency motion, and the chain at fairleads is the most critical fatigue location for all three cases. Conversely, the least critical fatigue location is the chain at the top of the bottom chain in case 1, while it is the chain at the seabed interaction point in cases 2 and 3. Results also show that the chain-polyester-chain system has more extended fatigue life than chain-chain-chain and chain-wire-chain systems. This paper also provides further recommendations for future work. Keywords: mooring system, offshore floating structures, global fatigue analysis, fatigue life, FPSO, wave frequency, low frequenc

THE POWER OF REPETITION AS RHETORICAL DEVICES IN SPEECH WITH REFERENCE TO OBAMA'S SPEECH AT UI JAKARTA

The power of a speech is judged from the content, the language and the delivery. This research deals the language used by Obama in his speech at UI Jakarta with the focus on repetition as one type of the rhetorical devices. The main question in this research is what makes Obama's speech admired by the public.This research is trying to identify the types of repetition employed, the impact of this choice and Obama's typical speech style. As a textual analysis, the data for analysis are limited to the speech text itself. Based onttne analysis, It is concluded that Obama employed four types of repetition as rhetorical devices in his speech: anadiplosis, conduplicatio, anaphora and parallelism.The impacts are that the speech text becomes cohesive, the message is intense, the sentences sound more poetic and powerful.

Word Classes According To Robins In His General Linguistics. An Interpretation

This paper aims at analysing R.H. Robins' idea on word c lasses or parts of speech in his book General Linguistics. The identification focuses on the number of parts of speech/word classes, the criteria used in the classification and the approach used. In making the interpretation, the writer refers to some other references for comparisons. From the analysis, it was found that Robins classified English Words into nine classes based on traditional approach and traditional grammar. The criteria used in the categorization is the syntactic relation, not semantic or morphological criteria. One word can be categorized into more than one class. depending on the grammatical relation in the sentence

English for the maids

This article deals with the design of the English course materials for the maids working for the expatriate families in Surabaya and focuses on the steps of the design process, starting from needs analysis using ADDIE approach, the problems in the implementation and the solutions. The first step in this approach is the analysis of the needy of the maids, followed by the next steps, that is, design and develop the course and implement it and finally evaluate the whole process. From the implementation, two main problems are identified The first problem is the tendency to read the model of dialog as they read Indonesian language due to their educational background In addition to the pronunciation problem, the second one is their tendency In avoid the formal grammar , especially the word order and sentence patterns .Based on the identifications of the problems. two alternative solutions are recommended: to provide the simple phonetic symbol to help them read/pronounce the words and to simplify the sentence patterns by deleting the auxiliary verbs in some contexts as long as it does not effect the meanin

Pengaruh Pemberian Ekstrak Daun Katuk (Sauropus androgynous L. Merr) yang ditambahkan Larutan Em-4 Melalui Air Minum terhadap Konsumsi Serta Kecernaan Bahan Kering dan Bahan Organik Induk Babi Sedang Bunting

Penelitian ini bertujuan untuk mengetahui kecernaan bahan kering dan kecernaan bahan organik babi induk sedang bunting yang diberi ekstrak daun katuk (Sauropus androgynous L. Merr) melalui air minum. Ternak percobaan yang digunakan dalam penelitian terdiri dari 12 ekor induk babi bunting dengan bobot badan antara 121-125 kg (rata-rata 122,5 kg dan berkoefisien variasi 1,46%). Metode dalam penelitian ini adalah metode eksperimen menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dan 3 ulangan. Adapun perlakuan dalam penelitian ini, yaitu R0 = pemberian air minum tanpa larutan ekstrak daun katuk, R1 = 60 gram ekstrak daun katuk dalam 5 ml EM-4/1 liter air minum, R2 = pemberian 120 gram ekstrak daun katuk dalam 5 ml EM-4/1 liter air minum, dan R3 = pemberian 180 gram ekstrak daun katuk dalam 5 ml EM-4/1 liter air minum. Variabel yang diteliti adalah konsumsi serta kecernaan bahan kering dan bahan organik. Hasil sidik ragam menunjukkan bahwa pemberian ekstrak daun katuk berpengaruh tidak nyata (P>0,05) terhadap konsumsi bahan kering dan bahan organik ransum, tetapi meningkatkan kecernaan bahan kering dan bahan organik dengan sangat nyata (P<0,01). Kesimpulan hasil penelitian ini adalah pemberian ekstrak daun katuk segar sebanyak 120-180 gram dapat meningkatkan kecernaan bahan kering dan kecernaan bahan organik induk babi bunting

TEACHING MATERIAL DEVELOPMENT: How to develop the communicative activities in Letera Indonesia, Book I.

The textbooks of Indonesian as a foreign language available at present are still limited and the one recommended by the MENDIKKBUD and widely used is Lentera Indonesia, first published by Pusat Bahasa, Departemen Pendidikan Nasional in 2004. Starting from the point that no textbook is suitable to meet all the needs of the learners in all contexts, this paper aims at identifying the gaps in each unit of the textbook and developing the communicative activities to achieve the fluency and accuracy in speaking. The data were taken from Lentera Indonesia, book I, Unit 1 to 10. From the analysis, it was found that there were no communicative activities to develop speaking skills, the sentence patterns were not controlled and the grammar exercises are not sufficient to achieve the accuracy and fluency. Based on the findings, it was recommended that the following communicative activities be developed to fill in the gaps in each unit: 1 ) identify one or two language functions and develop some communicative activities on a given context, 2) identify all the questions words related to one topic and develop the question-answer activities and 3) transformation drills to achieve the accuracy
