Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
89 words
An improved system for mooring tankers to an emergent fixed structure fixed to the sea bed, comprising an articulated structure for connecting the tanker to the fixed structure, said structure including an equalizer hinged to the tanker deck by hinges able to isolate said articulated connection structure from the tanker rolling motion, said structure also including a swinging boom made up of ballast chamber, said swinging boom in said articulated connection structure is constituted by tubular rods and said structure further includes two ties hinged to said swinging boom.
Claim 2
Dependent Claim
89 words
An improved system for mooring tankers to an emergent fixed structure fixed to the sea bed, comprising an articulated structure for connecting the tanker to the fixed structure, said structure including an equalizer hinged to the tanker deck by hinges able to isolate said articulated connection structure from the tanker rolling motion, said structure also including a swinging boom made up of ballast chamber, said swinging boom in said articulated connection structure is constituted by tubular rods and said structure further includes two ties hinged to said swinging boom.
Claim 3
Dependent Claim
42 words
The improved mooring system as claimed in claim 1, characterized in that said swinging boom moves about the vertical axis of rotation and about only one horizontal axis of rotation, namely that orthogonal to the vertical plane of symmetry of the system.
Claim 4
Dependent Claim
29 words
The improved mooring system as claimed in claim 2, characterized by being connected to a fixed structure able to carry flow lines from the sea bed to the surface.
Claim 5
Dependent Claim
29 words
The improved mooring system as claimed in claim 1, characterized by being connected to a fixed structure able to carry flow lines from the sea bed to the surface.
