Our assets Production platforms, subsea wells and an onshore gas treatment facility
As one of the larger operators active in the southern part of the North Sea, Wintershall Noordzee currently operates 26 production facilities on the Dutch, English, German and Danish continental shelves. The 5 main platforms (F16-A, K13-A, L8-P4, P6-A and A6-A) are manned 24/7 and the 15 satellite platforms surrounding the main platforms are normally unmanned. All our assets, including our 6 subsea wells, are monitored from the nearest manned location and/or from our Remote Controlled Operations center in Den Helder.
The majority of Wintershall Noordzee’s production facilities can be found in the Dutch sector of the North Sea. The oldest still producing facility is our manned P6-A production platform which was installed in 1982. The youngest facility Ravn, to be found on the Danish continental shelf, was installed in 2015. Wintershall Noordzee only has one onshore asset which is the Q8-terminal in Velzen-Noord, near IJmuiden. This onshore gas processing facility has been in production since 1986. It accommodates the gas coming from the normally unmanned Q1-D and Q4-C offshore facilities, brings it up to specification and transports it into the national gas grid.
Wintershall Noordzee B.V. based in Rijswijk (The Netherlands) was first established in 1965 as Pennzoil Nederland Company, a pioneering independent operator. Wintershall Holding acquired the company in 1989, subsequently adding Clyde Petroleum to its portfolio in 2003 to create the basis of the company it is today.
As one of the larger producers of natural gas in the Dutch sector of the Southern North Sea, Wintershall Noordzee operates more than 20 offshore installations. In recent years, the company has further expanded its operated portfolio to the continental shelves of the United Kingdom, Germany and Denmark.
Facts & Figures Average annual gas production of 6.5 BCM
23 producing facilities & 1 onshore gas processing facility
5 manned platforms
15 normally unmanned satellite platforms
6 subsea completions
F16-A production platform Located on the Dutch continental shelf
The F16-A manned production platform is located approximately 140 kilometers northwest of Den Helder on the Dutch continental shelf. On board, the natural gas from the E18-A field is cooled, dried and compressed before it is transported via the Noordgastransport gas transportation pipeline system to the onshore gas treatment station in Uithuizen in the north of the Netherlands. The 27-meter high platform comprises 7 levels and has a weight of 3600 metric tons. Its desalination unit and small natural gas driven power plant make the platform fully self-supporting.
K13-A production platform Located on the Dutch continental shelf
Originally installed in 1975, the manned K13-A production platform, located approximately 110 kilometers to the northwest of Den Helder, served as a gas production platform and central hub for many years. It currently does not produce from the original field or its surrounding satellite platforms, but is nowadays used for many other purposes. The Head of Mining Installation (HMI) and the rest of the crew use this platform to supervise the nearby K18-G subsea wells which are operated by NAM and which tie into their K15-FA-1 platform. In addition, the K13-A platform is an integrated part of the West Gas Transport pipeline system, connecting the J6-A production platform (Centrica) and the K5-A production platform (Total) to Den Helder. Finally, K13-A also hosts the Wintershall Noordzee radio-operator, the offshore aviation center and serves as a KNMI weather station.
L8-P4 production platform Located on the Dutch continental shelf
The manned L8-P4 compression platform, located approximately 81 kilometers to the north of Den Helder, provides gas compression, dehydration services, water treatment, accommodation and operational support to the nearby satellite platforms L8-P, L5-B, L5-C, L6-B and the L8-A West subsea well. The produced gas is exported from L8-P4 via the Noordgastransport gas transportation pipeline system to the onshore gas treatment station in Uithuizen in the north of the Netherlands.
P6-A production platform Located on the Dutch continental shelf
Located approximately 73 kilometers west of Den Helder, the manned P6-A compression platform has been in operation since 1983. It too provides gas compression, dehydration, water treatment, accommodation and operational support, in this case to the nearby P6-D, P12-SW, Q4-A and Q4-B satellite platforms and the P9-A and P9-B subsea wells. The produced gas is exported to L10-A complex (ENGIE) and then transported via the Noordgastransport gas transportation pipeline system to the onshore gas treatment station in Uithuizen in the north of the Netherlands. This platform also provides gas processing services for other gas producers.
A6-A production platform Located on the German continental shelf
The manned A6-A production platform is located on the German continental shelf, approximately 320 kilometers to the north of Den Helder. Gas and condensate production started in September 2000 and the field is now in tail-end production phase with 3 producing wells. Since the beginning of 2017, the A6-A platform is also used for the processing and exportation of oil from the RAVN production platform, located in Danish waters. Both the A6-A gas production and the RAVN produced oil are exported via subsea pipelines to the F3-FB-1 platform (ENGIE), located on the Dutch continental shelf. From there the oil is collected by tanker and the gas is transported further via the NOGAT gas transportation system to the onshore gas treatment station in Balgzand near Den Helder.
Remote Controlled Operations (RCO) RCO center located in Den Helder
The Remote Controlled Operations (RCO) center in Den Helder has been operational since 2007 as an important milestone in further optimizing operational efficiency. The center uses an advanced radio controlled system to monitor the production operations of our offshore production platforms and satellites. The center ensures that production is carried out safely and as efficiently as possible and monitors 24/7 all our ongoing operations.
Q8-Terminal Onshore gas processing facility
The Q8-Terminal, in use since 1986, is Wintershall Noordzee's only onshore gas treatment facility where the produced gas from the offshore Q1-D and Q4-C fields is processed and compressed before it is directly fed into the Dutch gas distribution grid. The facility is located on the TATA Steel yard in IJmuiden and can handle up to 1.2 mio m3 of gas per day. The facility is manned during normal working hours. Outside of these hours, monitoring takes place from our Remote Controlled Operations center in Den Helder.
