Due to the special nature of the seabed,especially the sea area where the seabed is basically composed of calcareous rock and sandstone,long-distance beach pull and pre-trench operations have great difficulties.This paper researches the key technologies for long-distance beach pull and pre-trench in hard seabed areas.The combination of seabed hard-layer crushing technology cornbined with the traditional bucket dredger can solve the problem of pre-trench operations in hard seabed areas.By adopting key technologies such as the uneven arrangement of buoys and pipeline grooving,the problem of long-distance beach pull in hard seabed areas can be solved.
