US Patent:

49826786, Jan 8, 1991

Filed:

Jun 1, 1989

Appl. No.:

7/359952

Inventors:

Carl R. Frederick - Plainfield NJ

Assignee:

Frederick Research Corp. - Plainfield NJ

International Classification:

B63B 2512

US Classification:

114 74R

Abstract:

An assembly for impeding the spillage of petroleum from a damaged oil tanker includes one or more liners made of permeable fabric material provided with reinforcing ribs in the shapes of triangles of two sizes. Triangles of a large size are surrounded by triangles of a small size, such that two small triangles are disposed along each side or edge of a large triangle. The small triangles thus have a side length approximately one half of the side length of the large triangles. The ribs are made of synthetic resin which permeates the fabric material. The liner material is also utilizable, particularly if coated, for a collapsible temporary storage bag which may be inflated in an emergency and pumped full of petroleum from a perforated storage compartment of a damaged tanker.

International Classification:

B63B 2512

US Classification:

114 74R

Abstract:

A device for impeding the flow of liquid cargo from a storage compartment of a water-traveling vessel upon damage to a hull of the vessel the device comprises a barrier member including (a) an upper portion of a flexible sheet material resistant to the liquid cargo and substantially impermeable thereto and (b) a lower portion attached to the upper portion and including a web of fabric material resistant to the liquid cargo and having a predetermined limited degree of permeability thereto. The flow impedance device further comprises reinforcement elements attached to the web for strengthening the fabric material and for at least inhibiting a tear from spreading in the web more than a predetermined distance from a point of perforation of the web. The flow impedance device also comprises bendable elongate resilient support members for supporting the barrier member inside the storage compartment of the water-traveling vessel. The web of fabric material is releasably attached to a panel of the barrier member via connector elements, facilitating replacement and maintenance of the permeable fabric web.

Abstract:

A device for impeding the flow of liquid cargo from a storage compartment of a water-traveling vessel upon damage to a hull of the vessel comprising a barrier member including (a) a sheet of fabric material resistant to the liquid cargo and having a predetermined limited degree of permeability thereto, and (b) reinforcement elements attached to the sheet for strengthening the fabric material and for at least inhibiting a tear from spreading in the sheet more than a predetermined distance from a point of perforation of the sheet. The flow impedance device also comprises support members for supporting the barrier member inside the storage compartment of the water-traveling vessel. The reinforcement elements take the form of a multiplicity of ribs disposed at a plurality of different angles with respect to each other. A related method for minimizing petroleum spillage into the environment upon damage to a petroleum-carrying water-traveling vessel on a body of water comprises the steps of (i) providing a bag constructed of fabric material having reinforcement ribs of synthetic resin material permeating the fabric material along the lengths of the respective ribs, (ii) unfolding the bag from a folded configuration, (iii) placing the bag on the surface of the body of water, (iv) pumping petroleum from a compartment of the vessel into the bag, (v) temporarily retaining the pumped petroleum in the bag, and (vi) removing the petroleum from the bag.
