Abstract
Abstract The arrangement is designed for anchoring underwater and underground pipelines laid in wet and flood lands with swelling ground and permafrost areas and also where pipelines with varying temperature and pressure have to be made fast in the ground. The arrangement comprises anchors secured in the ground. A fastening element attached to the pipeline is connected to the anchors through resilient connecting means capable of changing their length under load. When ground swelling occurs, the forces set up by transverse displacement of the pipeline are taken by the resilient connecting means. The resilient connecting means can also be used for placing preload on the pipeline in order to increase its adhesion to the ground.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
79 words
A pipeline anchoring arrangement comprising first fastening means interacting with the outer surface of the pipeline; second fastening means secured in the ground; at least one resilient connecting means coupling said first and second fastening means to each other, said resilient connecting means changing its length elastically when the pipeline is acted upon by disturbant forces exerted across the axis of said pipeline, said connecting means restoring its initial length after the action of said disturbant forces is removed.
Claim 2
Dependent Claim
79 words
A pipeline anchoring arrangement comprising first fastening means interacting with the outer surface of the pipeline; second fastening means secured in the ground; at least one resilient connecting means coupling said first and second fastening means to each other, said resilient connecting means changing its length elastically when the pipeline is acted upon by disturbant forces exerted across the axis of said pipeline, said connecting means restoring its initial length after the action of said disturbant forces is removed.
Claim 3
Dependent Claim
43 words
An arrangement as claimed in claim 1, in which the first fastening means comprises a crossbar positioned over the pipeliNe and connected thereto by a resilient connecting means, each end of said crossbar being joined direct to an anchor secured in the ground.
Claim 4
Dependent Claim
48 words
An arrangement as claimed in claim 1, in which the first fastening means comprises a crossbar positioned underneath the pipeline and rigidly connected to a band embracing the pipeline, each end of said crossbar being connected by a resilient connecting means to a pile secured in the ground.
Claim 5
Dependent Claim
33 words
An arrangement as claimed in claim 1, in which the first fastening means comprises a band embracing the pipeline and connected by one resilient connecting means to an anchor secured in the ground.
Claim 6
Dependent Claim
32 words
An arrangement as claimed in claim 1, in which said first fastening means comprises a band embracing the pipeline and connected by two resilient connecting means to anchors secured in the ground.
Claim 7
Dependent Claim
122 words
A pipeline anchoring arrangement comprising first fastening means interacting with the outer surface of the pipeline; second fastening means secured in the ground; at least one resilient connecting means coupling said first and second fastening means to each other, said resilient connecting means changing its length elastically when the pipeline is acted upon by disturbant forces exerted across the axis of said pipeline, said connecting means restoring its initial length after the action of said disturbant forces is removed, said first fastening means comprising a crossbar positioned over the pipeline and rigidly connected thereto, each end of said crossbar being joined by said resilient connecting means to said second fastening means, said second fastening means being an anchor secured in the ground.
Claim 8
Dependent Claim
122 words
A pipeline anchoring arrangement comprising first fastening means interacting with the outer surface of the pipeline; second fastening means secured in the ground; at least one resilient connecting means coupling said first and second fastening means to each other, said resilient connecting means changing its length elastically when the pipeline is acted upon by disturbant forces exerted across the axis of said pipeline, said connecting means restoring its initial length after the action of said disturbant forces is removed, said first fastening means comprising a crossbar positioned over the pipeline and rigidly connected thereto, each end of said crossbar being joined by said resilient connecting means to said second fastening means, said second fastening means being an anchor secured in the ground.
Claim 9
Dependent Claim
82 words
A pipeline anchoring arrangement comprising first fastening means interacting with the outer surface of the pipeline; second fastening means secured in the ground; at least one resilient connecting means coupling said first and second fastening means to each other, said resilient connecting means being substantially a cylinder with a spring-loaded piston and piston rod, said cylinder and piston rod being connected between said first and second fastening means, said resilient connecting means having sealing means for preventing earth from entering the cylinder.
Claim 10
Dependent Claim
82 words
A pipeline anchoring arrangement comprising first fastening means interacting with the outer surface of the pipeline; second fastening means secured in the ground; at least one resilient connecting means coupling said first and second fastening means to each other, said resilient connecting means being substantially a cylinder with a spring-loaded piston and piston rod, said cylinder and piston rod being connected between said first and second fastening means, said resilient connecting means having sealing means for preventing earth from entering the cylinder.
