SAL Heavy Lift’s MV Frauke wraps up project offshore West Africa
SAL Heavy Lift’s specialist vessel MV Frauke has completed a long-term project off West Africa. The vessel started the project in July 2014 and finalized it in December 2014.
The project consisted of seven phases:
- Mobilization and special preparation of the vessel in Germany and the Netherlands
- Loading and transport of two empty carousels from the Netherlands to the US, both 12-m (39-ft) tall with a diameter of 26 m (85 ft), weighing 620 tons (562 metric tons)
- Spooling of more than 2,000 tons (1,814 metric tons) of umbilicals in the US
- Transport of the fully-spooled carousels to the project site offshoreWest Africa
- Onsite support for the installation vesselS3000 offshore West Africa over a two-month period, including assistance for discharging of full carousels and the reloading of empty carousels at double banking
- Transport of the empty carousels back to the Netherlands, discharging
- Demobilization of the vessel in Germany in December.
SAL Heavy Lift said that the project’s significant challenge was the precision required on the weight-spreading calculation on the hatch covers. The stability of the hatch covers was ensured with tailor-made steel supports, which were installed beneath the hatch cover. A special grillage was designed to spread the weight of the heavier carousel.
