Pelayaran merupakan rute kapal yang akan ditempuh menuju pelabuhan tujuan (port destination) dalam upaya mendukung industri maritim. Pendistribusian logistik menjadi kebutuhan masyarakat, memiliki kepastian waktu memaksimalkan pelayanan prima dan jaminan keselamatan. Sehingga kinerja Second Officer membuat perencanaan pelayaran, sangat menentukan kelancaran operasional di MT. Seaborne Petro. Tu...

This paper provides a theoretical basis to directly estimate moments of transverse relaxation time T(2) from measured CPMG data in grossly inhomogeneous fields. These moments are obtained from Mellin transformation of the measured CPMG data. These moments are useful in computing petro-physical and fluid properties of hydrocarbons in porous media. Compared to the conventional method of...

We present a new Lagrangean approach for the pooling problem, a fundamental problem in the petro-chemical industry. The relaxation targets all nonlinear constraints, resulting in a Lagrangean subproblem with a nonlinear objective function, that is reformulated as a linear mixed integer program. Besides being used to generate lower bounds, the subproblem solutions are exploited within Lagrangean...

Magnetic Resonance finds countless applications, from spectroscopy to imaging, routinely in almost all research and medical institutions across the globe. It is also becoming more frequently used for specific applications in which the whole instrument and system is designed for a dedicated application. With beginnings in borehole logging for the petro-chemical industry Magnetic Resonance sensor...

Many processes operate only arounda limitednumber of operation points.In order to have adequatecontrol around each operation point, an adaptive controller couldbe used.Then,if the operationpoint changesoften, a largenumberof parameters wouldhavetobe adapted overand over again. This prohibits application of conventional adaptive control, whichis more suited for processes with slowly changing par...
