OUR RECOMMENDATIONSOnce the vendor/system and shipyard has been selected, the owner should establish a communication channel between the shipyard and the vendor ASAP.
Depending the chosen execution strategy, a project manager, either from the shipyard or from the vendor, should lead the execution. Our experience is that vendors cannot manage retrofits outside their premises.
Our experience has shown that it is most efficient and economic to allow the shipyard to produce the simple but bulky part of the equipment such as the pipe spools.
Clear demarcation list between yard, owner and vendor supplies.
Logistics and planning should be robust to ensure timely execution.
EXECUTION STRATEGIESSCENARIO 1: HOLISTIC PROJECT MANAGEMENT & EXECUTION
