Single Point Anchorage Systems

Ronstan Certified Fall Arrest Systems for working outside conventional guardrails in marine environments

Removable Screw-in Padeye


Single point anchorage systems have long been used to provide an attachment point for crew when cleaning the hull, superstructure and windows of large motor yachts and other vessels.

With today’s greater awareness of workplace risks, boat builders and surveyors are seeking to ensure a high standard of safety by specifying systems that are purpose designed, tested and standards-approved.

Ronstan supports this approach, which can only improve the safety and security of the persons using these systems in their everyday work, and has developed Single Point Anchorage systems which have been tested and certified by Lloyd’s Register to the relevant European and Australian Standards.

System Description

The removable Screw-In Padeye Anchor Device consists of two parts:

  • A structural anchor base which is permanently fixed to the structure.
  • A screw-in anchor for connection of personal protection equipment.
    • The structural anchor base is to be permanently fastened to the structure using 4 x M6 fasteners.
    • The screw-in anchor is attached to the structural anchor base by means of a central threaded spigot. Once fully threaded in place the anti-rotation locking screw must be engaged to ensure that the anchor cannot unintentionally become detached from the structural anchor base.
    • The screw-in anchor has a single attachment point for personal protection equipment.

  • Removable screw-in padeye anchorages are certified to the European standard EN795:2012, Type A, as well as the Australian standards AS1891.4.2009 & AS5532:2013.
  • Marine grade 316 stainless steel structural anchor base, screw-in anchor device and identification plate.
  • Identification plate with manufacturer’s markings and unique serial number.
  • The screw-in anchor device can be removed from the structural anchor base when not in use for safety or maintenance. It should always be locked to the base when in use using the locking screw.


Ronstan Fall Arrest Systems are tested and certified to relevant European and Australian Standards, by Lloyd’s Register, Copenhagen (Denmark), and are appropriate for single person use with an energy absorber to the EN355 standard. They must only be used with personal protection equipment (harnesses, lanyards, fall arresters and other devices) that are approved to the relevant CE or other standards for such equipment. Each harness or device must be secured to a separate attachment point.
