ABSTRACT:
A cable burying device (3) comprises several heavy hollow tapered elements (7, 8) coupled to each other (7A, 7B, 8A, 8B) to provide limited flexibility, which is towed along the seabed and which digs a trench, the cable (1) passing through the length of the device to become buried in the trench. A guide tube (2) to guide the cable (1) from the ship to the burying device (3) has a flexible lattice construction (FIGS. 6, 7, 8) which can be folded flat for ease of storage on the ship.
