Figure 6.29 – SPAR Projects

                   The world’s first production Classic SPAR, Neptune, was installed in the Gulf

               of Mexico in 1996. Oryx Energy developed Neptune, and was later acquired by

               Kerr-McGee in 1999. The Classic SPAR  hull is basically a cylinder (fig. 6.30).

               This  cylinder  is  separated  into  three  main  sections:  1.  Upper  section  –

               compartmentalized  and  filled  with  air  to  provide  the  buoyancy;  2.  Centerwell  –

               flooded with seawater; 3. Keel section (“Soft Tank”) – compartmentalized to aid in

               transportation. Also contains any field-installed ballast.
