Slant Rig Self Elevating Structure

DETAILS

Client name: PERENCO GABON
Project name: Slant Rig Self Elevating Structure
Duration: 400 man-days

Project Description

Basic and detailed engineering of a self-elevating structure for a 35° slant rig. This rig was initially designed to drill water wells with no BOPs. The deeper drilling depth requires a BOP system, which was not originally planned. The structure was designed to lift the drilling truck by 3,7m to allow installation of 11” or 7” BOP stacks.

Activities / Tasks and Solutions developed by Dolfines

Dolfines has provided detailed engineering of the elevating structure.

Project Results

The structure is in service in Gabon for Perenco drilling operations.
