Abstract

Conventional fenders designed for onshore berths are not suited to the large heave and rolling motions experienced offshore. An invention is described that uses existing and proven elements in a new configuration to systematically address vessel motions in an off-shore berthing situation. Two cone fenders support a horizontal axle on which a pivoted frame is mounted. The frame in turn mounts a minimum of three rollers that make axial contact with the ships hull. This type of fender could be used at any offshore facility where parallel berthing is required.

Offshore Environment Berthing Fender

ABSTRACT

Conventional fenders designed for onshore berths are not suited to the large heave and rolling motions experienced offshore.  An invention is described that uses existing and proven elements in a new configuration to systematically address vessel motions in an off-shore berthing situation.  Two cone fenders support a horizontal axle on which a pivoted frame is mounted.  The frame in turn mounts a minimum of three rollers that make axial contact with the ships hull.  This type of fender could be used at any offshore facility where parallel berthing is required. 

I.          BACKGROUND

Fenders presently used to berth ships at offshore facilities were designed for berthing vessels at sheltered onshore berths or for fendering two vessels coming alongside each other - lightering. 

·         Fenders designed for on-shore berths (Fixed Panel) are not suited to the large heave and rolling motions experienced offshore.

·         Fenders designed for lightering cannot be adequately moored to withstand all off-shore conditions and therefore have to be fitted with expensive lifting mechanisms that are difficult, and potentially hazardous, to operate.

III.       DESCRIPTION OF THE INVENTION

The invention is composed of the following components:

·         Flat panel fender supported on its horizontal axis by two or more compression fenders

·         Single horizontal roller supported by two or more compression fenders

·         Multiple horizontal rollers on a frame that it pivoted on its horizontal axis.  The frame axis being supported by two or more compression fenders
