Title: Heating of subsea pipelines
Inventor: MERIC PAKKAN
IPC: F17D1/18
Filed: 2018-12-04
Abstract: A method of maintaining production of hydrocarbon fluids subsea, preferably of mitigating or removing a plug (54, Fig.5a) of solid-state material such as coalesced wax or hydrate. Flow of hot production fluid (36, Fig.3) is directed from a subsea well 28 into a production flowline pipe 14 extending to a processing or storage location 40. In a first mode of operation, preferably a normal flow mode, a flow of service fluid (42, Fig.3), preferably monoethylene glycol (MEG), is transported from a source of service fluid 44 to a service fluid pipe 16 that extends adjacent to production flowline pipe 14. Service fluid (42, Fig.3) is injected intermittently from service fluid pipe 16 into well 28 or the production fluid (36, Fig.3) flow upstream of flowline pipe 14. In a second mode of operation, preferably a heating mode activated on plugging or a determined risk of plugging of flowline pipe 14, at least some of the flow of production fluid (36, Fig.3) is diverted into service fluid pipe 16. Heat from production fluid (36, Fig.3) is applied to service fluid pipe 16 and transferred to flowline pipe 14. There is also a subsea hydrocarbon production system 26.

Title: Friction stir welding process
Inventor: HOWARD JAMES PRICE
IPC: B23K20/12
Filed: 2021-01-13
Abstract: In friction stir welding (FSW) a joint, e.g. a lap joint or a T-joint, successive passes of the FSW tool can be offset, incorporating ‘cold lap defect’ (CLD) regions of the previous FSW pass, to create a better final weld. Cold lap defect regions may be created when relatively cool material on the trailing edge side of the stirring pin is drawn back into the joint, with a cooler temperature lowering weld quality. Thus FSW can create a good weld on a leading edge side of a rotating probe; and an inferior weld on the trailing edge side of the pin. A spaced apart second pass of the probe may heal the cold lap defect created from the first pass; substantially eliminating a CLD region.

Title: Mass spectral encoding
Inventor: MARTIN RAYMOND GREEN
IPC: H01J49/42
Filed: 2021-03-29
Abstract: A method of mass spectrometry comprises applying one or more AC excitation voltage waveforms to electrodes of an ion guide to attenuate ions having mass to charge ratios within respective mass to charge ratio windows. The AC excitation voltage waveforms cause the ion guide to act as a mass to charge ratio notch filter. The one or more AC excitation voltage waveforms is varied with time such that ions having different mass to charge ratios are attenuated with different attenuation time profiles, e.g. ions with different mass to charge ratios are attenuated at different unique times. The method may further comprise obtaining precursor ions data and product or fragment ions data, and associating product or fragment ions with precursor ions by matching their detected attenuation time profiles. Two or more AC excitation voltage waveforms (or notches) may be applied simultaneously and varied with time to provide increased specificity.
