NorSea Group - Not just a pipe dream

The company has been deeply involved in offshore construction for the past 50 years, and this year, NorSea Group has embarked on a project to complete the longest ever pipeline in the southern hemisphere.

NorSea Group's core activity focuses on the Norwegian Continental Shelf, but with international expansion a key part of its expressed strategy, it is increasingly seeing opportunities arise overseas.

Having last year bought the Danish logistics company Danbor, a supplier to Mærsk Oil and the Danish Underground Consortium, the firm also has activities in Montrose, Peterhead and Aberdeen, UK, as well as a newly established office and warehouse facilities in the port of Den Helder, in the Netherlands. In Greenland, Danbor operates a base joint venture called Arctic Base Supply.

With its positions in Norway, the UK, Denmark and the Netherlands, NorSea Group offers unique coverage of the entire North Sea basin.

Logistics products for the oil and gas industry

With nine strategically located onshore supply bases along the Norwegian coastline, NorSea Group supplies base services and integrated logistics solutions to the oil and gas industry in Norway.

From Stavanger in the south to Kirkenes in the north, the company provides the Norwegian oil and gas industry with a broad range of logistics solutions and services, including supply chain management, marine and engineering services, IRM and mobilisation services, and project logistics.

Supply bases for offshore facilities

All of NorSea's supply bases offer secure and sheltered berthing, a strong quayside and good water draft. The company ensures a safe and cost-effective turnaround of calling vessels through close inspections, qualified personnel, scheduled maintenance programmes, and its modern fleet of cranes and transport equipment.

Bunkers, drinking water, and dry and wet bulk materials are available on all quaysides. NorSea Group's supply bases also have high numbers of tenants, providing additional services to the offshore oil and gas industry.
The NorSea Group's supply bases in Norway comprise the following recourses:

  • 4,325m of quaysides
  • 127,960m² of offices
  • 70,500m² of workshops
  • 264,700m² of indoor storage and 1.56 million square metres of outdoor storage
  • 3.25 million square metres of supply bases.

The company's equipment fleet comprises:

  • trailers/flats
  • terminal tractors
  • forklifts with safe working load (SWL) of 2-45t
  • cranes with SWL of 45-220t.

Players in pipeline construction

Since 1965, NorSea Group has played an important role in projects involving the construction of offshore fields and platforms in the North Sea. In 1998, the company widened its specialist areas to support pipeline installations, and today, it has experience working on more than 20 pipeline projects, from which several subsea pipelines are the largest ever built.

In 2006, NorSea Group completed a logistics contract with Norsk Hydro, installing the Langeled Pipeline between Norway and the UK. The pipeline measured 1,166km and comprised 1.1 million tons of 42 and 44 CWC linepipes.

Between 2009 and 2012, the company also completed construction on the Nord Stream Projects, in contract with Eupec Pipecoatings. Running from Russia, through the Baltics, to the northern shore of Germany, the project consisted of two 1,220km stretches of 48 CWC linepipes, weighing 4.72 million tons.

In 2015, NorSea Group has undertaken a contract with Saipem to complete the Ichthys Export Pipeline, running between the offshore fields in Western Australia to Darwin, NT. With a total length of 889km and a weight of 1.46 million tons, the 40 CWC pipeline will be the longest ever build in the southern hemisphere.

Safety in pipeline operations

NorSea Group's engineers have joined forces with the designers of Reach Stackers and Mobile Harbor Cranes in order to achieve improved technical solutions and design for pipehandling.

The result is the company's hydraulic spreader bar, which enables efficient pipehandling while removing the risk of injury to personnel in dangerous operations.
