Lay Down Area Installation - K6-P Platform, Total E&P Nederland

Offshore lifting challenges

There are always ways to realize lifting capacity on an offshore platform. Finding the best solution requires experience and skill. 

Conbit always goes the extra mile to obtain the best result for its clients. In this case, Total E&P Nederland contracted them to provide the lifting engineering for the lay-down area (LDA) extension of its K6-P gas production platform in the Dutch Continental Shelf of the North Sea.

Temporary lifting solution to place lay down area in position

Temporary lifting solution 

Since the available deck crane could not be used for this lifting operation, Conbit provided an alternative solution. To enable lifting of the LDA extension, weighing 17.5MT, temporary lifting devices were installed on the platform’s main deck. Conbit was responsible for the design and engineering of the lifting structure,including all the structural analyses that were required to ensure safety ofthe system.

The challenge

The LDA extension had to be lifted directly from the supply vessel vertically. This posed an extra challenge because it needed to be horizontal for its installation on the platform. The Conbit team of engineers devised a novel concept where the LDA extension is lifted in hinges then rotated for its installation onto the north side of the platform. 

Once the team positioned the LDA extension in hinges, they used pull cylinders to move the lift booms backward and rotated the LDA extension into the correct horizontal position. 

Conbit was also responsible for the load-out and sea fastening of the LDA extension.

Lifting equipment 

For this project, Conbit used the following:

  • Two lifting winches
  • Two modular lifting systems
  • Power packs
  • Two lift lines for the lifting systems
  • Mini-crane to install/assemble the lifting system
  • Water bag for load testing
