Dry‐docking Blocking Line for Stolt Offshore’s 25,000Te “Seaway Polaris” (2002)

This reinforced concrete blocking line was engineered for Stolt Offshore and installed in Cape Town’s Sturrock dry‐dock by Wale Marine as a turn key solution. The fabrication of the 144 No cruciform shaped 200 Te SWL precast concrete units was sub‐contracted to Concrete Units. This contract received the Fulton Commendation for excellence in Design in the use of concrete by The Concrete Society of Southern Africa.

In 2008 the converted Polaris incorporating a new J lay tower and weighing 30,000 Te was re‐docked for maintenance in Cape Town by Acergy. Once again the new blocking line that was engineered and installed by Wale Marine (in JV with Concrete Units). The new blocking line design incorporated the original blocks, but required further blocks and extra modifications to allow for a quicker installation time.
