Offshore Cable Installation - Lillgrund - Vattenfall

December 2, 2006:
Figure 10. The motor installed with the wheel pressing onto the cable at the capstan.
With the help of the electric motor and wheel, the whole length of the cable was loaded
onboard. An average speed of loading of 5-6 meters per minute was planned, but at times
the speed was exceeding 10 meters per minute. When the loading was finished, a fibre
test confirmed that the tension in the cable was accurate.
5.1.3 Pre-laying and bad weather conditions
The issues identified during loading raised questions about the ability to lay and reload the
cable in the case of bad weather conditions. Carrying out a pre-laying exercise in a
neighbouring archipelago solved this.
Before the pre-laying exercise was carried out, a new construction was added to the
“gooseneck” which included an extra vespa. The new construction was an extension of the
“gooseneck” where the vespa was built-in, figure 11.
