Efficiently capture manufacturing know-how to support reuse 

As experienced manufacturing planners and workers are approaching retirement, it is critical that shipyards capture existing knowledge and experience. In addition, they need to better leverage this information to optimize their production processes. Specifically, marine and offshore companies need to reuse their existing knowledge and previous production planning experience to reduce their cycle time while improving product quality. They are challenged to make this know-how available in an easily reusable form within their multi-disciplinary environment and across their multi-site organization.

With Optimized Production For Sea, shipbuilders can build process templates that describe the different activities and how they are done, which can then be reused for each new shipbuilding project. By making sure that company standards are embedded in the manufacturing planning, production planners no longer need to start from scratch, saving considerable preparation time and money. Companies can define the types of machines available at the shipyard with their characteristics and production capacities so that planners can select the right equipment for a particular task. They can also customize templates by adding their own equipment’s attributes. Moreover, shipyards can embed company knowledge in the form of rules to ensure that the production planning complies with corporate preferences, guidelines and conventions.

Efficiently develop manufacturing assembly definition to support work preparation and production 

The production of any large ship or offshore platform is a major undertaking involving a large ecosystem. One of the first major steps in any such project is to define the build strategy including the block definitions and the manufacturing assemblies within each block. This is fundamental information that forms the foundation of the production planning process. It is therefore critical that this assembly process leverages existing company knowledge and experience to define assemblies that are optimized for production within the specific shipyard.

Optimized Production For Sea transposes an engineering BOM, organized by system, into a manufacturing BOM, which is organized by block. It details what needs to be built and the sequence of operations required to build each block.

Key Highlights and Benefits

  • Reuse standard manufacturing assembly templates
  • Manage, view, and navigate large manufacturing assemblies
  • Generate cross-discipline manufacturing assemblies directly from engineering design data
  • Effectively manage engineering changes with automatic propagation to reduce downstream errors and rework
  • Quickly and easily identify which design objects are not included in the manufacturing planning
  • Generate assembly drawings

Create and automate steel structure work preparation to optimize manufacturing

The fabrication and assembly of the ship structure is a core undertaking of the shipyard. The process to convert the engineering design of the ship structure into manufacturing plans to support the fabrication and assembly was long considered an “art” that only highly specialized “loftsmen” could successfully undertake. As technology has taken over the design and manufacturing planning of ships, the process of structure work preparation has started to become more and more automated. A key challenge in today’s modern shipbuilding environments is for shipbuilders to leverage existing “lofting” expertise with integrated design and manufacturing solutions to lead to more efficient and effective structure work preparation and production.

Optimized Production For Sea provides tight integration between design and manufacturing information that allows Structure Production Preparation to correctly interpret the design information that defines the stiffeners and to automatically create the markings where these stiffeners will be positioned and welded.

Develop process plans and 3D work instructions to support manufacturing

As today’s ships and platforms are becoming larger and more sophisticated, the process to build them needs to adapt and evolve to ensure they are produced as efficiently as possible. A process plan is a critical component of a ship or platform’s manufacturing lifecycle. It defines the sequence of how products are built, the operations that are involved, the human and machine resources that are used to perform the operations and the instructions that are needed to build the ship or platform.  What is challenging here is the ability to validate the process plan before execution starts. 

Optimized Production For Sea enables to validate each step of the process plan, simulate the execution, and identify bottle necks and issues. It also helps process engineers to adjust the process plan and optimize it to ensure an efficient and effective production execution.
