Technology Selection Process Using SPEC Tool

This document is a guide detailing the technology selection process for ships' power and energy systems using the Ships Power and Energy Concepts (SPEC) tool. It outlines the stages of Marine Power Systems Design at MARIN, which include operational analysis, technology selection, functional system design, system dimensioning, and ship arrangement concept. The guide emphasizes the importance of integrating new energy and power systems for emission-free shipping. It discusses the challenges of comparing power and energy technologies, noting factors such as energy density, power density, costs, readiness levels, energy efficiency, and emissions. The SPEC tool employs a multi-criteria approach to evaluate various technologies early in the design phase, providing an independent ranking based on operational data. Additionally, it highlights the benefits of SPEC-based services for decision-makers in ship design, including insights into alternative solutions and their implications for design choices. The document also mentions the availability of data on the Sustainable Power portal, developed by MARIN and ESSF.
