Abstrak :
Suatu re-engineering analysis oleh lembaga independen dilakukan terhadap platform-platform lepas pantai penunjang kegiatan eksplorasi dan produksi suatu area kontrak bagi hasil yang akan habis service lifenya untuk menentukan apakah platform-platform tersebut layak untuk dipergunakan kembali atau tidak selama jangka waktu tertentu kedepan hingga kontrak bagi hasil area tersebut berakhir. Dengan pendekatan manajemen resiko berdasarkan ISO 31000, perpanjangan service life platform-platform berdasarkan hasil re-engineering analysis ini akan di analisa resikonya untuk mengetahui tingkatan resiko dan akibatnya terhadap orang, lingkungan, aset, serta reputasi pada perusahaan yang mengoperasikan platform-platform tersebut sehingga dapat ditentukan langkah-langkah mitigasi yang akan diambil untuk menghilangkan atau mengurangi dampak dari resikoresiko tersebut dengan mempertimbangkan keekonomisan masing-masing lapangan dalam kaitannya untuk menjamin pemasukan pendapatan bagi negara dan perusahaan. ......A re-engineering analysis was conducted by an independent body to some extended service life offshore platforms that supporting exploration and exploitation activities for one of the production sharing contract company to decide whether the platform is feasible or not to be utilized during certain time in the future until the production sharing contract is expired. By the risk management which refer to ISO 31000, the risks from the extended service life of the platform will be analyzed to find out their risk level and its impact to people, environment, assets, and company reputation, therefore some mitigation actions can be made to avoid or minimize its impacts by considering the economical aspect of the oilfield in conjunction with ensuring positive income for both government and company.

This book is designed to serve as a core text for courses in advanced engineering mathematics required by many engineering departments. The style of presentation is such that the student, with a minimum of assistance, can follow the step-by-step derivations. Liberal use of examples and homework prob­lems aid the student in the study of the topics presented. Ordinary differential equations, including a number of physical applica­tions, are reviewed in Chapter One. The use of series methods are presented in Chapter Two, Subsequent chapters present Laplace transforms, matrix theory and applications, vector analysis, Fourier series and transforms, partial differential equations, numerical methods using finite differences, complex vari­ables, and wavelets. The material is presented so that four or five subjects can be covered in a single course, depending on the topics chosen and the completeness of coverage. Incorporated in this textbook is the use of certain computer software packages. Short tutorials on Maple, demonstrating how problems in engineering mathematics can be solved with a computer algebra system, are included in most sections of the text. Problems have been identified at the end of sections to be solved specifically with Maple, and there are computer laboratory activities, which are more difficult problems designed for Maple. In addition, MATLAB and Excel have been included in the solution of problems in several of the chapters. There is a solutions manual available for those who select the text for their course. This text can be used in two semesters of engineering mathematics. The many helpful features make the text relatively easy to use in the classroom.
