Work must be allocated to the most cost- effective locations, and work centres added or removed as the project progresses, to use capacity wherever it exists.
An understanding of the design
ultimately drives the procurement and supply chain process and so there should be appropriate integration with the design environment. Yet the technologies typically used can actually reduce access to the complete and accurate information set that is vital in the making of key project decisions. Needless to say, these weaknesses can have a cascade effect across the entire project. Incorrect materials and delivery delays jeopardise work order and resource planning, which damages project schedules and impacts on production efficiency, costing time and money. Integration between design applications
and production is also key to the process. A well-managed production infrastructure is characterised by the completion of a vessel that meets all defined quality standards and is delivered on time and within budget. Mismatches between design and production can have a massive impact on project schedules and can make the difference between the design environment and the production environment is, once again, all too oſten hampered by silos that prevent information from delivering any real benefit.
Global business, global liabilities One of the most significant changes in the shipbuilding industry over the last two decades has been the specialisation and globalisation of shipyards and suppliers, highlights Mr Neuveglise. As there has been an improvement in product efficiencies and reduced costs, a growing number of major vessel projects rely on them for strategic components and assemblies. The result has been the relentless rise of out-sourcing and the increasing need to establish and maintain effective working relationships with suppliers around the globe. Likewise, on the design side, the use
of subcontracting design companies or agencies has grown impressively. Shipyards have been dealing with global suppliers for decades, but the services, technology and assemblies being provided now demand

a much higher degree of integration – right from the design stage. Complete subsystems must be tightly coordinated with key project milestones and technical certifications. Yet, more oſten than not, there is no ability
to apply the same level of management and overview to extended shipyard activities as is applied to on site activities. Te inability to create a fully integrated extended shipyard environment compromises the predictability, efficiency and quality of vessel projects and inadequate integration of design technology is firmly at the root of it, he comments.
Integration is the key Mr Neuveglise believes that it would be wrong to lay all the blame for inefficient project execution at the design technology door. True, design technology that is not properly integrated into the wider shipbuilding process can be as much a liability as an asset, he highlights. However, the real issue is the effective integration of the valuable design information into all aspects of the shipbuilding process. Recent activity in the industry has
confirmed this, say Aveva Solutions. Aveva has recently acquired a new business, Logimatic MARS, in order to bring more integrated shipbuilding capability to its offering. Te Aveva MARS solution that
has resulted derives much of its strength from the 3D design ability of the existing Aveva Marine (design) solution, but at the same time it is very much a purpose designed shipbuilding process management system. It optimises the project control, logistics, materials management, resource and production planning processes used by shipyards (as distinct from other manufacturing industries) as is in use in all kinds of shipyard projects, including commercial and naval newbuild, repairs, refits and conversions, outfitting and offshore. Mr Neuveglise has highlighted that
Sedef, a Turkish-based shipyard is currently part of one of these projects. According to Cumhur Kuter, Sedef general manager, this solution has helped in “reducing project cycles and so bringing down our total costs” and has put the shipyard’s fortunes “in safe hands”.
Sedef integrates with Aveva MARS Established in 1982, Sedef is situated on the Bay of Tuzla, near Istanbul, the yard has expanded continuously. It has recently completed the production of a new dry dock and added a 500tonne portal crane. Sedef currently employs some 600 workers (roughly 400 in production and 200 in the offices) and nearly 1400 subcontractors.
