NIGERIA: FLOATING PRODUCTION PLATFORM - CHEVRON

Between 1997 and 1998, Crowley provided submersible transportation of several concrete floating production platforms from the US Gulf to offshore Nigeria. Crowley won this contract based on the detailed proposal submitted which included all aspects of the submersion processes for the transport barge, design and fabrication of sea fastenings and discharge operations as well as the coordination of all support craft and inland movements. This operation, as do many of Crowleys projects of this nature, required detailed analysis of the stability and structural integrity of both the cargo and the transportation unit to ensure a safe and efficient operation. Importation into Nigeria also requires detailed co-ordination between all parties involved due to the nature of the legal and political system. Because of the sensitivity of the project, Crowley was able to arrive in Nigeria, remove sea fastenings, shift the concrete barges to site and depart Nigerian waters within 48 hours of initial arrival: a record for submersible transport to Nigeria which still stands.

The platforms were transported to the Benin River, discharged, and moved up river to a nearby, smaller river to the job site.
