The Nord-West Oelleitung GmbH (NWO) in Wilhelmshaven was founded in November 1956 to build and operate the Nord-West-Oelleitung as the first mineral oil pipeline in Europe. With the construction of the mineral oil pipeline, the supply of raw materials to several mineral oil refineries in the Emsland and the Rhine-Ruhr area was ensured. The deep-water port in Wilhelmshaven, which even the largest tankers can call at, was decisive for the choice of location .

The NWO is Germany's hub for the handling, storage and transit of mineral oil . More than 1 billion tons of mineral oil have been handled with over 18,000 tankers since the facilities were commissioned on November 29, 1958. In 2018, 15.5 million tons of mineral oil were handled, which were delivered by 197 tankers.

The operating facilities essentially include the tanker extinguishing bridge for unloading the tankers, the tank farm on the premises for the interim storage of mineral oil and the mineral oil pipelines with all associated technical equipment.

Half of the mineral oil supplied comes from Europe . A third comes from Russia and around 20% from Africa .

Since the start of operations in November 1958, the newly built Wilhelmshaven oil port has developed into the most important mineral oil import port in the Federal Republic.

The NWO is a participant in the BIL portal and provides line information via the nationwide information system for line research (BIL) operated by the cooperative .

Pipeline connections

North-west oil line

North German oil pipeline

The North German oil pipeline , which is operated by NWO , also begins in the Wilhelmshaven oil port . Nord-West Oelleitung GmbH is the management company for this line.

  • Task: Supply of the Holborn Europa refinery in Hamburg-Harburg
  • Route: Wilhelmshaven - Hamburg
  • Length: 142 km
  • Diameter: 56 cm

Other facilities

The plants of Nord-West Oelleitung GmbH are connected to three cavern plants of the strategic crude oil reserve in Wilhelmshaven-Rüstringen , Etzel and Ochtrup . The caverns are underground storage facilities in salt domes that have been washed out with (sea) water at a depth of around 900 to 1700 meters.

Other facilities

The company premises in Wilhelmshaven have a total area of ​​170 hectares.

Tank farm

The tank farm has a total capacity of 1.6 million m³:

  • 26 floating roof tanks with a capacity of 30,000 m³ each.
  • 9 floating roof tanks with a capacity of 100,000 m³ each

Port facilities, tanker bridge

  • Extinguishing bridge, consisting of
    • an access bridge that extends eastward 670 m into the edge of the fairway
    • a north-south running cross section of about 1200 m length on which the extinguishing heads are located
  • today three erase heads (see below under history)
  • Tanker sizes up to 260,000 dwt.
  • partially loaded a. A. up to 350,000 tdw.

Remote control center

The entire line is remotely controlled and monitored by a remote control center on the Wilhelmshaven site. All slides and sensors can be accessed from there. Two dispatchers are responsible on the one hand for the tank farm including the extinguishing bridge and on the other hand for the pipelines and their installations.

The basis for operation is the pumping plan , i.e. which mineral oil batches are sent in which order to which customers along the pipeline. The batches are sent directly one after the other without a separating pig . The buyers often have an urgent need for special batches and it is important to supply all of them fairly. Therefore, a lot of optimization work is done.

Pumping stations

There are three pumping stations for the NWO line: in Wilhelmshaven itself (with four pumps of up to 3.2 MW output, all others only with two pumps), in Ostenwalde and in Ochtrup . There used to be a fourth, namely in the Mülheim / Ruhr plant (see below). The maximum achievable pressure (directly behind the first pumping station) reaches 65 bar.

The oil then flows through the line at approx. 3 to 5 km / h, i.e. about pedestrian speed. That sounds very slow, but it is achieved continuously around the clock and leads to acceptable transfer times.

Mülheim facility

There is another facility on the site of the former Mülheim pumping station. The southern section of the NWO pipeline is looked after from here.

history

  • 1956 - the company was founded
  • 1958 - Start of operation with three extinguishing heads and a single pumping station (in Wilhelmshaven)
  • 1961 - highest number of employees: 230
  • 1963 - The pumping station in Ostenwalde goes into operation
  • 1966 - Commissioning of the last (fourth) pumping station in Mülheim
  • 1971 - Commissioning of the fourth extinguishing head
  • 1973 - Commissioning of the parallel 40-inch line to Hünxe, which was built because of the increased capacity requirements
  • 1974 - The new extinguishing head 4 was completely destroyed in an accident by a tanker while docking and was rebuilt in an improved form
  • 1984 - Sale of the 40-inch line from km 55, is now operated as a gas line
  • 1999 - extinguishing heads completely renewed, only three pieces left
  • 2006 - Celebration of the 50th anniversary, so far 850 million tons of mineral oil throughput, 142 employees
  • 2014 - Celebration of envelope 1 billionth ton

Incidents

  • 1964 in Emsland
  • On October 3, 1966, the pipeline in the twilight forest near Schermbeck tore and thousands of liters of mineral oil flowed into the forest. After days of use, the oil can be kept away from the lip .
  • On December 5, 1972, around 1000 cubic meters of crude oil leaked through a leak in the NWO pipeline on the site of the pumping station near Ochtrup .
  • On November 18, 1973, the pipeline broke near Dinslaken , approx. 60,000 liters of crude oil flowed into the Rotbach and adjacent soils. Oil barriers and the extraction of the oil were carried out by 150 firefighters.
