Abstract: A float assembly securable to an elongate conveyance wherein the elongate conveyance defines a longitudinal axis and the float assembly has a roll axis parallel with the longitudinal axis. The float assembly includes a first buoyant float member coupled with the float assembly. The float assembly also has a configuration wherein buoyancy and gravitational forces acting on the float assembly resist rotation of the float assembly about the roll axis when the float assembly is secured to the elongate conveyance and disposed in a body of water. In some embodiments, the float assembly includes a body defining a buoyant pipe support that includes a central float section and two outer float sections disposed laterally outwardly from the central float section. In some embodiments, ballast is used to provide roll axis stability. In yet other embodiments, the float assembly includes a keel member to enhance roll axis stability.

Abstract: A float assembly including at least one float member securable to an elongate conveyance wherein the float members are nestingly stackable when not in use. In another form, the float assembly includes two float members wherein each of the float members define a radially inward facing generally arcuate surface having one or more clamping members extending radially inward wherein securement of the two float members to a generally cylindrical conveyance engages the clamping members with the conveyance. The float members may also include an alignment projection and recess wherein the alignment projections of each of the float members are inserted into the alignment recesses of the opposing float member when the float members are secured about a conveyance. In another form, the float assembly includes at least one float member having a plurality of projections which define openings for the fork of a forklift.
