Barret Wolber

A floating marine barrier is provided whose main components all have substantially equal elastic characteristics, enabling the barrier to better absorb and arrest an impacting vessel. Embodiments include a floating marine barrier including barrier modules each having a flotation device, a supporting framework attached to the flotation device, and impact net support posts attached to the supporting framework. An impact net is attached to each of the support posts and extends between the barrier modules along a longitudinal axis of the barrier; and a main tension strength element is attached to each of the barrier modules and extends between the barrier modules along the longitudinal axis of the barrier to space the barrier modules from each other. The impact net has a first elasticity, and the first main tension strength element has a second elasticity which is substantially equal to the first elasticity.

Compliant single net marine barrier

A marine barrier system is provided with two elongate buoyant members, a net support member between and above the two buoyant members, an elongate load bearing member spaced from and between the buoyant members, and a lower ballast member between the two buoyant members and below the buoyant members. Stanchions extend between the members to support them and maintain the spacing between them. An impact net is attached to the net support member and the load bearing member. When a moving vessel impacts the impact net, the net deflects to transfer a force of the impact to the net support member, the stanchions, the load bearing member and the buoyant members, which engage the water to transfer the impact force to the water and arrest the motion of the vessel. The ballast member provides a force to restore the barrier to an upright position when the barrier rotates from vertical.

Marine barrier systems

A marine barrier has a line of buoyant column modules, and an impact net attached to and extending between the column modules. First and second lines of buoyant flotation modules are respectively disposed parallel to and on opposing sides of the line of column modules, and are connected to the column modules by legs such that each of the flotation modules is retained between two adjacent ones of the center column modules. When the barrier is floating in a body of water and a moving vessel impacts the impact net, the impact net deflects to transfer a force of the impact to one or more of the column modules and flotation modules, which in turn engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.
