“Minimal Facility Platform L6-B”
By Peter Valkenier
Wintershall has for many years been an operator in the south of the North Sea, in the relatively shallow waters of the Dutch sector and operates currently 23 platforms and about 1,300 Km of pipelines.
Cost reduction and cost saving have been a central part of our philosophy, which has led us support the development of many innovative strategies in development and operations.
We have recently designed and constructed a re-usable platform L6-B of which foundation and topside has been installed in one go. One of the particular problems we face is CO2 corrosion in satellite flowlines with High Pressure High Temperature developments. We have addressed this by shifting the operating envelope to low pressures and by pre-cooling the product before putting it into the pipeline. So using a relatively short length of small diameter Duplex as a cooling loop we can use conventional carbon steel.
Normally when selecting the materials for flowlines on developments such as these one would use seamless pipe, we however have championed the use of High Frequency Induction HFI pipe, which is significantly cheaper and generally seems to have a greatly reduced lead times.
As many of our offshore facilities are normally unmanned with restricted emergency accommodation, we have been one of the early adopters of the walk to work strategy, for offshore maintenance, with the use of a motion compensated walk way; this allows out personnel a far better overnight accommodation and access to better work facilities adjacent to the platform.
About the presenter:
Peter Valkenier has been working in the offshore industry for more than 20 years. After his study, he joined a construction company in the Netherlands and worked in the Project Management department. He was dealing with new-built platforms and major offshore modifications for Dutch operators. He changed over to the Commercial department where he was responsible for the marketing- and sales activities within the Oil and Gas Industry. In 2007 he joined Wintershall Noordzee B.V. as Project Manager for a compression project and for the abandonment of a satellite platform project. His current position as from 2008 is that of Engineering and Construction Manager.
