Abstract

"APARELHO PARA ESCAVAçãO SUBMARINA". é apresentado um aparelho para escavação submarina aperfeiçoado (30a, b, c). Os aparelhos conhecidos ressentem-se de um número de problemas, p.ex., eficiência e controle de movimento. Em conseq³ência, a invenção proporciona um aparelho para escavação submarina (300a, b, c) que compreende um corpo oco (370a, b, c) tendo pelo menos uma entrada (371a, b, c) e pelo menos uma saída (373a, b, c), pelo menos um par de rotores (335a, b, c), (340a, b, c) coaxialmente deslocados um do outro e girantemente montados no corpo oco (370a, b, c), e dispositivos para acionar os rotores em direções de rotação contrárias. O aparelho para escavação submarina (300a, b, c) compreende um par de entradas horizontalmente opostas (371a, b, c) comunicantes com uma única saída (373a, b, c) a saída (373a, b, c) sendo dispostas verticalmente para baixo substancialmente a meio caminho entre as duas entradas, em uso. O aparelho para escavação (300a, b, c), por conseguinte, pode ser substancialmente em forma de "T" ou em forma de "Y". Os dispositivos para acionar os rotores (335a, b, c), (340a, b, c) podem incluir pelo menos um motor de perfuração (310a, b, c).
