... A new technology called Local Heating offers the possibility of significantly raising the temperature of the multiphase production fluid in order to improve flow assurance and consequently the economics of field developments. Heating the flowlines is a way to overcome the thermal constraints...

... Abstract To address flow assurance challenges, Integrated Production Bundle (ETH-IPB) and Heating Cables Replacing Armour Wires (ETH-HCRAW) have been developed. These two technologies use electrical cables, which provide heat to the fluid by Joule effect. They are different in their design...

... Abstract The purpose of this publication is to present the development and qualification of an innovative heat traced flowline concept. Heat Tracing is a relevant solution for long tieback or when relying on a standard or hybrid production loop is not economical or not feasible. This concept...

... This paper describes a new direct electrical heating method which offers unique flow assurance opportunities in flexible pipe systems. The method effectively expands the operational envelope of flexible unbonded pipes by offering prevention/removal of hydrate plugs, mitigation of vax...

... Electrically Traced Heated Pipe in Pipe (ETH-PiP) technology has been developed to overcome some of the challenges associated with deeper and more remote offshore oil and gas production. This active heating technology applies power to achieve a production fluid temperature above the wax...

... Abstract The use of induction heated bends for offshore pipelines and topside pipinghas been an industry practice for many years. However, with the use of higherstrength steels, such as API5LX70M and X80M, there is a need to understand theinduction heating and cooling parameters which may have...

..., the geomechanical changes could potentially be catastrophic if triggering large slides of the seafloor. In this study we investigate two cases of coupled hydraulic, thermodynamic and geomechanical behavior of sloping oceanic HBS: hydrate heating as warm fluids from deeper conventional reservoirs ascend...

... Abstract In this study we evaluate the response of oceanic subsurface systems to thermal stresses caused by the flow of warm fluids through non-insulated well systems crossing hydrate-bearing sediments. Heat transport from warm fluids, originating from deeper reservoirs under production...

... heat losses to the environment. In addition to high steady state insulating performance, the system muat also provide good transient cool down behaviour to prevent the formation of wax or hydrate during shut down and to minimise the time required to resume production. A number of solutions have...

... Abstract The novel technique of applying electrical heating to prevent hydrate formation in multiphase pipelines has been successfully applied on the Norwegian Continental Shelf. The first pipelines where direct electrical heating (DEH) is applied have recently been put into operation. DEH...
