The vessel was originally built at Hyundai Mipo in 2001. The rebuilding was performed in two phases. The first phase was completed at A&P Teesside last summer. There all the cable laying equipment and the shelter deck were removed. Two large pipe carousels and a helicopter deck was installed. Further the main deck was strengthened to 10 t/m2.
The second phase at Damen, involved the installation of a 200 t offshore crane (300 t inshore), a 340 t lay tension lay tower, a 400 t heave compensated deployment winch system, ROVs and additional accommodation/office space. The vessel's beam was increased from 21.0 m to 27.0 by adding sponsons.
Multi Maritime's involvement has been design development in cooperation with Acergy Group, lines design and stability documentation.
When designing the lines for the sponsons, great emphasis was put into fairing the sponsons smoothly into the existing hull. Although this meant a more complicated construction, it paid of in that the vessel loose very little speed due to the sponsons. In fact it reached a speed of 16 knots during the sea trials.
The Polar Queen left the conversion yard in mid August 2007. Its first jobs are in West Africa, namely pipelaying in the Moho Bilondo and Kizomba C fields.
