DEME GroupConversion of a bulk carrier into the “Yellowstone” fall-pipe vessel
MULTI.engineering executed the full engineering cycle for the conversion, starting with a FEED study to define the fundamental characteristics of the oriented vessel and assessing the pros and cons of newbuilding versus conversion.
As a result of the study, a bulk carrier was selected for conversion into a fall-pipe vessel capable of supporting a range of international offshore wind activities. The work then progressed to the concept design phase, including initial modelling, naval architecture activities and defining the overall conversion approach.
This was followed by the basic design phase with delivery of the complete Class-approval package.
It includes structural calculations, preliminary stability & motion assessments and marine system development. A complete 3D scan of the donor vessel enabled overall integration of new systems and early clash detection. Class and Statutory documentation, equipment arrangements and schematics were finalised into a solid basic engineering package.
The detail design phase comprised the complete engineering package for the shipyard PaxOcean in Singapore, including production drawings, on-site system integration and coordination with the owners’ supplied equipment.
I especially appreciated the short lines of communication. All their engineers were easily accessible to work together to find the best possible solutions
