A custom-built, infrared system from Heraeus Noblelight has helped the Barrier Group, of Wallsend, to develop a high performance, thermal insulation system for submarine pipelines, which offers significant advantages over conventional systems.

The high power infrared system is used to cure adhesive to ensure that a polypropylene material, which imparts impact resistance, corrosion protection and additional thermal insulation, can be efficiently applied to an innovative insulation shell around a conventional steel pipe. This results in reduced lay tension, together with significant improvements in pipe-laying productivity.

The Barrier Group has established a well-earned global reputation for providing corrosion protection coatings for steelwork and pipelines in the oil and gas sector. It has now diversified into areas such as passive fire protection, metal spraying, powder coatings and subsea insulation. One result of this has been the development of the patented Bubbletherm system, where a conventional steel pipe is enclosed with epoxy syntactic insulation and the whole assembly is further insulated and protected with a wrapping of a proprietary polypropylene material.

Subsea pipelines are used to carry oil and oil/gas mixes from subsea wellheads to onshore refineries or offshore processing platforms. Oil discharges from wellheads at temperatures, typically, between 80ºC and 160ºC. To prevent wax and hydrate formation, which could restrict oil flow, it is important that the oil does not cool significantly in the ambient subsea temperatures.

Consequently, pipe insulation is vital. Conventionally, this achieved by pipe-in-pipe manufacture, where the annular space between the inner and outer pipes is filled with lightweight insulation material. This kind of pipe is expensive to produce and because it uses two individual steel pipes, it is also heavy. As a result, a reel pipelaying vessel can only carry a restricted tonnage, which, in turn, restricts the length of pipe it can lay before returning to port for re-loading. With the new Bubbletherm pipe, which is cheaper to produce than competitive pipe, it is now possible to lay pipe with reduced reload cycles and with lower levels of tension. When the pipe is laid from a “S” lay vessel, it is possible to lay 20 km of pipe in 11 days compared with the 45 days of its pipe-in-pipe counterpart.

An important step in the manufacture of the new pipeline system is the application of the polypropylene protective wrap. This is carried out as a continuous process, where the wrap is overlapped to provide a three ply coating. The infrared system comprises five modules, with a total of 24, QRC short wave emitters delivering a total power of 50.4kW. The first module is used to provide rapid activation of the adhesive on the wrap, while the second module heats the top of the wrap to maintain flexibility.

The third module provides additional heat before the wrap is brought into contact with the insulation and the final two modules apply heat to the insulation as it is rotated to ensure that hot adhesive is not applied to a cold surface. Precise temperature control is provided by optical pyrometers for modules 1, 3 and 5.

The QRC emitters used in this application provide high energy short wave radiation rapidly and responsively. They feature a new quartz reflective coating with a special nano-and micro-structure, which provides the reflector with very high diffusion characteristics to ensure the stability of process parameters, such as temperature and coating homogeneity. As Dave Robinson, adhesives consultant at Barrier, explains, “The high power and the response of the infrared emitters are vital to the curing process. The Heraeus units are capable of bringing the adhesive very rapidly to its working temperature and, just as importantly, they can switch off very quickly, so that there is no damage to the wrap material.”

Heraeus specialises in the production and application of high quality energy sources covering the electro-magnetic spectrum from ultraviolet to infrared. It has over 40 years experience in infrared technology and offers the expertise, products and systems to provide efficient and effective solutions to drying, heating and curing problems throughout industry.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
