Abstract

fetched live from OpenAlex

En el presente trabajo de fin de grado, abordaremos el estudio de las operaciones de carga y descarga ejecutadas a bordo de un buque quimiquero de última generación. En concreto, analizaremos la carga de monoetilenglicol y dietilenglicol y la descarga de una solución acuosa de sosa cáustica, llevadas a cabo de manera simultánea, por el buque petroquímico Panagia Thalassini, en el puerto de Vancouver (Canadá), durante los días 3 y 4 de diciembre. Lo interesante, de este caso real, consiste en la descripción de la solución dada a un problema surgido durante la operativa, el cual consistió en la parada de emergencia de la descarga, debido a un problema en la terminal, al redirigir la carga de un tanque a otro, por lo que el desembarque de sosa caustica se detuvo durante 2 horas. Realmente, el problema no fue provocado por la parada sino por las bajas temperaturas (3˚C). La temperatura de solidificación de la solución de sosa cáustica es de 12ºC. Consecuentemente, la carga comenzó a solidificarse en el interior de las líneas de descarga. Las medidas tomadas para que la sosa no obstruyese la línea consistieron en un trasvase de carga desde el tanque número 3 estribor a la pareja de tanques número 7 para, posteriormente, calentar con vapor de agua las válvulas que habían sido inutilizadas por la sosa solidificada. Además, en este TFG, explicamos los procedimientos previos a la operativa, esto es, el estudio de compatibilidad de las sustancias manejadas, el plan de carga y el calentamiento de la sosa cáustica.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
