Abstract:
An arrangement (1) on board a vessel to be able to strap at least one cable (2) to a pipeline (3) during continuous and contemporary deployment of the strapped pipe bundle (4) into the sea is shown. The arrangement includes at least a strapping machine (6) which is arranged to be moved forward together with the cable (2) and pipeline (3) in order to perform a strapping operation in concert with the forward advancement thereof. The strapping machine is also moveable rearwards relative to the cable and pipeline for the repositioning to the next strapping operation such that the application of a strap or straps (7) takes place intermittently under the continuous deployment of the pipe bundle. Means (8) for continuous motorized advancement of the respective pipes and cables towards the strapping machine (6) and further into the sea is also arranged.
Abstract:
An apparatus, system, and method are disclosed for concurrently forming a plurality of pipelines 212. The apparatus includes a support chassis 202 coupled to at least one transportation facilitation member 204. The transportation facilitation member 204 facilities the movement of the support chassis 202 along a surface. A first pipe fuser 214 is disposed on the support chassis 202 and is configured to fuse a first section of pipe 224 to a first pipeline 212. A second pipe fuser 214 may also be disposed on the support chassis 202. The second pipe fuser 214 may be configured to independently fuse a second section of pipe 224 to a second pipeline 212. The first pipe fuser 214 fuses the first section of pipe 224 to the first pipeline 212 with the support chassis 202 in a stationary position. The second pipe fuser 214 fuses the second section of pipe 224 to the second pipeline 212 with the support chassis 202 in the same stationary position.

Abstract:
The present disclosure is directed to embodiments of composite tubing having properties tailored to meet a wide variety of environmental and working conditions. Composite tubes disclosed herein may include one or more of the following layers: a internal liner, a composite layer, a thermal insulation layer, a crush resistant layer, a permeation barrier, buoyancy control layer, a pressure barrier layer, and a wear resistant layer. Grooves may be provided in one or more layers of the composite tube to provide increased axial permeability to the composite tube. A venting system, including vent paths, may be provided in the composite tube to vent fluid that may become trapped within the wall of the composite tube.
Abstract:
An insulated hollow structure (1, 1a, 1b), such as a pipe (1a) or a tank (1b), for storing and/or guiding a fluid having a temperature above 140°C during the storing and/or guiding in said insulated hollow structure (1, 1a, 1b) is provided. The insulated hollow structure (1, 1a, 1b) comprises insulation layers (3, 4) enclosing an inner wall (2) of the hollow structure (1, 1a, 1b), which insulation layers (3, 4) comprises a first inner insulation layer (3) and a second insulation layer (4). The first insulation layer (3) comprises an aerogel based insulation material which has been applied in a liquid state to a surface (2a) of said wall (2) of the hollow structure (1, 1a, 1b) and then subsequently cured after being applied, before providing a second insulation layer (4). The second insulation layer (4) is a spray foam insulation layer enclosing the first inner insulation layer (3) and the inner wall (2) of the hollow structure (1, 1a, 1b). The invention moreover relates to use of an insulated hollow structure in the maritime environment, and a method of providing an insulated hollow structure.
Abstract:
Method of manufacturing a tube (1; 8); the method includes a first step of partial vulcanization of an intermediate tube (2) having a first layer (3) made of polymeric material, a reinforcement layer (4) and a second layer (5) made of polymeric material; a coating step, during which a third layer (6) of polymeric material is arranged around the intermediate tube (2); and a second vulcanization step, which is completed during the vulcanization of the above mentioned first, second and third layers (3, 5, 6), thus reducing the risk of damage to the third layer (6).
Abstract:
A method of sealing an annulus between inner and outer pipe sections (18, 12) of a pipe-in-pipe system comprises: positioning a sealing mass (30) in the annulus in contact with the inner and outer pipe sections; deforming the sealing mass, for example by shearing and compression, by effecting relative longitudinal movement between the inner and outer pipe sections; and fixing the inner and outer pipe sections against reverse relative longitudinal movement to maintain deformation of the sealing mass. The inner pipe section and a displaced outer pipe section may be fixed by welding them to respective pipes of an adjoining pipe-in-pipe structure. Opposed ramp surfaces, each being similarly inclined relative to the longitudinal direction, extend into the annulus from respective ones of the pipe sections such that the sealing mass may be compressed between the ramp surfaces.
Abstract:
Thermally insulated solar pipeline for the transport of fluids comprising: a first conduit (11, 12); an insulating layer wrapped around said first conduit (11, 12) and coaxial thereto; said insulating layer comprising a support layer (13) treated with aerogel; characterized in that said support layer (13) treated with aerogel is completely coated with a containment layer (20, 21) before being wrapped around said first conduit (13); and that an outer layer (15) wraps and is coaxial to said insulating layer of said first conduit (11, 12); said outer layer (15) comprising at least one longitudinal lateral flap (25).
Abstract:
The present disclosure relates to a double-wall construction for an engine exhaust conduit (22). The construction includes an inner conduit (22i) and an outer conduit (22a) surrounding the inner conduit. An insulating annular gap (23) is defined between the inner (22i) and outer (22o) conduits. A spacer structure maintains the gap between the inner and outer conduits. The spacer structure (5) can be unitary with at one of the inner and outer conduits (22i, 22o).
