Marine Operations

Marine operations cover installation design and analysis of structure deployment and lay analysis of rigid pipelines, flexibles and/or umbilical’s/cables.

Modelling and analysis consist of:
  • The design and planning phase shall provide weather criteria.
  • The execution phase of marine operations shall be based on the weather forecast.

The pre- and postprocessor enables you to idealize a product model based on geometric information and then simulate how that model will behave under certain real-life conditions. The degree of control offered by the pre- and postprocessor is vital to increasing model quality while decreasing analysis time. The risks of poor model quality and accuracy increase as models and analyses grow in complexity.

A pre- & post-processor is used together with a hydrodynamic solver in marine operations to create and prepare input and to display and review results. The pre-processor serves a model from project source data, such that a data interface is realized between the analysis solver software and model source data. Therefore, it provides the ability to control the input model and the ability to modify the model to ensure it will produce the intended result. The post-processor allows full control of results selection and a set of tools to manage and display results.

The usability of the interface is supported by commonly used interface types that are well integrated in the windows environment where one important feature is the interaction and data transfer with third party software products such as Word and Excel.

Application Programming Interface - API

Some software packages can be driven via an application programming interface (API), as well as being used as a normal Windows program. An API is a connection between computer programs, or a type of software interface, offering a service to other pieces of software. This application is such a software that uses an API to support in the aero- and hydrodynamic modelling and analysis.

A methodology for hydrodynamic modeling in offshore renewables is outlined using integration with a hydrodynamic solver. The application programming interface (API) is used to integrate applications in order to perform a task to share data and to execute pre-defined processes. For example, hydrodynamic simulation requires some preparation to be done before it can be numerically set up and performed. This step is called pre-processing input data, in order to idealize a physical design and create a model for analysis.

The API enables idealization of a model based on geometric and environmental information and then simulate how that model will behave under certain real-life conditions.

This Figure is showing the three stages linked together by file.

Following hydrodynamic simulation, a post-processor is used to analyze and present the simulation results and customize the representation. The postprocessor imports and displays the results and helps the understanding of model behavior. It has the ability to perform some analysis work on the output, for example extreme load analysis and statistics. An editor provides the environments and the tools to create reports, including model visualization and charts.
