The Company
A trusted EPC powerhouse evolving into renewables
JGC brings large-scale project delivery expertise and a strong engineering heritage. As offshore wind grows in Japan and the region, JGC recognised the need to bolster its cost and schedule estimation capabilities with simulation insights — ensuring tighter control of offshore wind project timelines, budgets and execution risk.
The Motivation
Enhancing accuracy in cost and scheduling for offshore wind
Offshore wind projects present high risks: unpredictable weather, complex logistics, and large component installation. JGC wanted a way to simulate development phases for better decision-making ahead of execution. Specifically, the goal was to reduce uncertainty in cost estimates, validate scheduling assumptions, and optimise resource allocation across multiple offshore wind builds.
The Solution
Partnering with Shoreline for simulation-based cost and schedule modelling
Using Shoreline’s simulation platform, JGC modelled project workflows, vessel and logistics scenarios, and installation schedules for offshore wind farms. The software enabled JGC to test various scenarios, refine cost forecasting, assess schedule risks, and make data-driven decisions early in project development — enhancing transparency and control before fabrication started.
The Results
Improved forecasting, reduced risk and smarter execution
By embedding Shoreline’s solution into its planning process, JGC achieved more accurate cost and schedule estimations, mitigated execution risks, and gained higher confidence in project outcomes. The collaboration strengthens JGC’s competitive edge in offshore wind engineering and positions the company for efficient, reliable project delivery as the market scales.
