With the advent of oceans as critical resources, ocean simulation technologies have gained momentum in various fields such as fisheries, marine biology, oil and gas. The complexity of such simulation systems not only shows through the system architecture, the data generation and analysis, but also through the cost to develop and reuse these systems. For the construction of ocean simulation environment, the current research is mostly aiming at single aspect or application, such as Marine Geographical Information System (MGIS), Virtual Ocean Battlefield, etc. These systems are designed and implemented using different platforms. These systems have limited scale, and are difficult to reuse. Based on our previous work, we propose in this paper a platform solution for composable ocean simulation environment (COSE). We first analyze the basic design elements and development requirements of the digital ocean system and surveys relevant methods; then we propose a new composable ocean simulation platform. It is based on Model Driven Engineering (MDE) methodology, and compatible to the IEEE High Level Architecture (HLA) standards. This platform forms a system simulation environment that includes architecture components (such as ocean fluid, life and resources) and connector (such as HLA Runtime infrastructure-RTI ) models, the model composition and decomposition methods with constraints, and the corresponding mapping mechanism. With this platform, a public warehouse can be built for the ocean models, which can be readily reused in further system development. The structure of the public warehouse is constructed as well.
