The 34-hour project was undertaken for Kvaerner Verdal and project manager Trond Nysæter said the operation was a record load out for Sarens Norway.
Sarens said the team completed the operation in record time, working in almost every weather condition, through rain, snow, sun and wind.
The team worked in two shifts and at peak, had 20 people on the job. Working together, they performed the skidding, jacket load out, ballasting, and engineering.
The project involved special considerations, including a 3.2m tidewater difference during load out. The team also had to work with a ballasting tolerance difference of 20mm between the barge and land skidways.
To handle the load, which measured 70m high, 140m long, and 90m wide, Sarens used:
- 16 200/185t strand jacks;
- 54 ballast pumps; and
- a computer-controlled tide ballast system.
The equipment was mobilised by truck, and the team spent two weeks rigging it up. During the operation, the team also had to adapt to challenges like slow skidding due to the heating of hydraulic power packs.
Here's how they did it:
