Steel-structured jacket or template platforms have been extensively installed in Persian Gulf offshore oil & gas fields. For the jackets in the water depth range of 40 to 80 meters in this region, utilizing the self-upending concept has been investigated.It has been concluded that designing the jackets, implementing the self-upending process for their installation operations, are economically and practically more convenient than the usual crane-assisted up-ending methods. Considering the required number of new installations for the new as well as brown-bag projects, and considering the existing problems and difficulties for the available marine spread, especially ready-to-work heavy floating cranes, utilizing this concept in the offshore industry seems to be a considerable break-through. This might have a significant effect on the renovations and reconstructions required in offshore oil & gas projects during the post-JCPA1Agreement period.
