Semisubmersible floating production systems (SFPSs) with steel catenary risers (SCRs) are attractive field-development solutions;
especially in deeper water of Western Australia. However;
SCR design is challenging in the offshore Western Australia environment because of severe cyclonic environments and persistent swells. This paper presents a comparison of three different field-development alternatives that use SFPSs with SCRs in deepwater Western Australia. These alternative solutions are a conventional semisubmersible hull design with steel lazy wave riser (SLWR);
a deep-draft semisubmersible hull design with conventional SCRs;
and a novel semisubmersible hull design with conventional SCRs. Copyright 2014 Offshore Technology Conference. Reproduced by permission;
