In a method of backfilling spoil (M) into a seabed trench (T), a blade (310) is propelled to travel forward on the seabed (S) and collect spoil (M) along the sides of the trench (T). The collected spoil (M) is funneled toward a rear apex (313) of the blade (310). The funneled spoil (M) is allowed to be discharged through an opening (311) in the blade apex (313) and onto the top surface of a pipe (C) disposed in the trench (T). The spoil (M) discharged into the trench (T) may then be leveled. The discharged spoil (M) may also be fragmented before it reaches the pipe (C).
