Abstract
A method, system, and device for deploying an oil spill containment boom at the side of a ship, barge, or other steel structure. Each end of the boom is connected to its own device that is configured to attach to a generally vertical surface of a steel-hulled ship. Attachment occurs through the use of magnetic force. Instead of encircling the entire ship with a boom, the device permits the establishment of specific containment areas around the ship. The device engages and disengage the side of the ship through the use of a cam and lever assembly to counter the magnetic force.
Claims16
A device for mounting onto a generally vertical surface of a marine structure, comprising:
- a body;
- a top portion of the body;
- at least one side portion of the body;
- a buoyant material affixed to the body, wherein the buoyant material is sufficient to keep the body afloat in a body of water associated with the marine structure from which the body was deployed;
- a first fitting affixed to the top portion of the body, wherein the first fitting is used to control a vertical movement of the body;
- a magnet affixed to the at least one side of the body, wherein the magnet is configured to attach to the generally vertical surface of the deploying marine structure;
- a second fitting affixed to the body for linking an object to the generally vertical surface of the marine structure;
- a disengagement arrangement for separating the magnet from the generally vertical surface of the marine structure;
- wherein the disengagement arrangement comprises:
- an arm;
- a distal end of the arm;
- and
- a proximal end of the arm;
- wherein the distal end of the arm is configured to contact the generally vertical surface of the marine structure;
- and
- wherein the arm is configured to detach the magnet from the generally vertical surface of the marine structure;
- and
- whereby the distal end of the arm extends beyond a contact face of the magnet during a lowering of the device;
- and
- whereby the distal end of the arm retreats behind the contact face of the magnet when the device is allowed to float in the body of water, thereby permitting the magnet to contact the generally vertical surface of the marine structure.

A system for deploying a containment boom, comprising:
- a containment boom;
- at least one marine structure bounded by a body of water, the marine structure having a waterline;
- a mounting device;
- a lowering and lifting arrangement for lowering and lifting the mounting device from the marine structure;
- wherein the mounting device has a magnet that attaches the mounting device to a surface of the marine structure near the water line;
- wherein the mounting device has a fitting at a top portion of the mounting device for connection to the lifting and lowering arrangement;
- wherein a buoyant material is affixed to the mounting device, the buoyant material sufficient to keep the mounting device afloat;
- at least one boom connector affixed to the mounting device;
- wherein the containment boom is connected to the mounting device with the use of the at least one boom connector;
- a disengagement arrangement for separating the magnet from the surface of the marine structure;
- wherein the disengagement arrangement comprises:
- an arm;
- a distal end of the arm;
- and
- a proximal end of the arm;
- wherein the distal end of the arm is configured to contact the surface of the marine structure;
- and
- wherein the arm is configured to detach the magnet from the surface of the marine structure;
- and
- whereby the distal end of the arm extends beyond a contact face of the magnet during a lowering of the device, and
- whereby the distal end of the arm retreats behind the contact face of the magnet when the device is allowed to float in the body of water, thereby permitting the magnet to contact the generally vertical surface of the marine structure.
18 more elements
A method for deploying a containment boom, comprising the steps of:
- positioning a magnetic mounting device adjacent an end of a containment boom;
- connecting a boom connector attached to the magnetic mounting device into a corresponding boom connector attached to the containment boom;
- lowering the magnetic mounting device and the containment boom from a marine structure toward a body of water, a cable or line being attached to the mounting device;
- activating a cam assembly by controlling tension on the cable or line;
- wherein the cam assembly projects an arm extending past a contact face of a magnet in the magnetic mounting device;
- positioning the magnetic mounting device adjacent a generally vertical surface of the marine structure;
- allowing the magnetic mounting device to float on a surface of the body of water;
- providing slack on the cable or line thereby deactivating the cam assembly wherein the arm retreats to behind the contact face of the magnet;
- and
- permitting the magnetic mounting device to be drawn toward and contact the generally vertical surface of the marine structure.
