California equipment manufacturer Apex BASE recently released a service bulletin regarding the stainless-steel rings on its risers. Owners should inspect their risers to see if the rings are bent. Deformed rings do not affect the rig’s performance or compromise the strength of risers—but they also don’t meet the company’s high-quality standards. Apex BASE is offering ring replacements, free of charge, to any customer who has been affected. See service bulletin for details and contact Apex BASE with questions.Download Apex BASE Service Bulletin SSR 4-16-01 – or view the original Service Bulletin announcement on the Apex BASE website.
