El problema de premarshalling CPMP consiste en recolocar los contenedores ubicados en una bahía del patio de una terminal de contenedores en el orden en que serán requeridos posteriormente. En este trabajo, estudiamos el CPMP con el objetivo de minimizar el tiempo total empleado por la grúa CPMPCT. Presentamos un algoritmo beam search adaptado a las particularidades del problema. En la fase de evaluación local, se proponen varios criterios de evaluación, en función del tipo de movimiento del contenedor; en la de evaluación global, se propone un nuevo algoritmo heurístico y una búsqueda local; por último, se proponen varias reglas de dominancia que permiten reducir el espacio de soluciones. Un extenso estudio computacional muestra que nuestro algoritmo alcanza el óptimo en las instancias óptimamente resueltas en la literatura, mejora las soluciones de las instancias en las que no se conocía el óptimo, pero sí una solución, y obtiene solución en las que no se conocía ninguna solución.
