In 2010 DONG Energy made an interesting oil find in the Danish North Sea, in the Solsort Prospect. An extensive data collection programme was carried out, and subsequently Ramboll assisted on a number of studies to assess the feasibility in developing the asset.

Early-phase studies for Solsort

Since 2011 Ramboll has assisted DONG Energy on a number of projects covering:

  • Feasibility study – evaluating three concepts and 22 alternatives
  • Concept selection study – evaluating two concepts
  • Backfil and early production study
  • Gas import study

Multidisciplinary services

Ramboll’s provision of services in the various studies has included e.g.:

  • Green field and brown field work
  • Process calculations
  • Technical safety
  • Equipment sizing and Master Equipment List
  • Piping, electrical, instrumentation
  • Topsides layout
  • Jacket design
  • Weight calculations
  • Cost estimates
  • RAM analysis (Reliability, Availability and Maintainability)

The water depth around the site is app. 62 m LAT.

Pipeline design

Ramboll also carried out evaluations of interfield pipeline options for the Solsort development. Ramboll’s work comprised:

  • Multiphase import pipeline from Solsort to host platform
  • Water injection pipeline from host to Solsort
  • SWAG-gas injection pipeline from host to Solsort
  • An umbilical for chemical injection, power and fuel
  • Hydraulic sizing and flow assurance studies for tie-back options

The flow assurance studies included evaluation of slugging, erosion hydrates and wax formation in the pipelines in order to optimize pipeline size and meet the host requirements. Different degrees of insulation were studied for this purpose.

In support of decision-making

For each study carried out, Ramboll has provided DONG Energy with another building block in their assessment of options for developing the Solsort asset.
