Talisman Malaysia Limited

Talisman Bunga Kekwa C Annex Platform: Conceptual Design and Installation

ICON Engineering undertook a conceptual review and recommended an annex monopod platform braced back to the existing BKC wellhead platform as the most cost effective solution for Talisman to add new wells on the BKC platform. The design concept was able to be installed by drilling rig or derrick barge.

Talisman Malaysia Limited (TML) required additional wells on the BKC platform.

The design concept was able to be installed by drilling rig or derrick barge. Although the initial plan was to use a rig, the platform was finally installed by ICON using the crane barge Seminole due to delayed arrival of the rig.

ICON worked through the Christmas – New Year period to re-engineer the installation procedures to suit the derrick barge. Offshore work was undertaken in the monsoon season of January 2007.
