Self-elevating installations (jack up units)

Provides information on aspects of self-elevating Installations with movable legs capable of raising the hull above the surface of the sea. The information is based on guidance previously contained in Section 33 of the Fourth Edition of the Health and Safety Executive's 'Offshore Installations: Guidance on Design, Construction and Certification'(1) which was withdrawn in 1998. As discussed in the Foreword, whilst the text has been re-formatted for Offshore Technology publication, the technical content has not been updated. The appropriateness and currency of the information contained in this document must therefore be assessed
by the user for any specific application.

Some of these research reports are very large, for information about expected download times please see our FAQs pages.
