PurposeThis paper designs an optimal closed-loop supply chain network with an integrated forward and reverse logistics to examine the possibility of remanufacturing end-of-life (EoL) ships.Design/methodology/approachExplanatory variables are used to estimate the number of EoL ships available in a closed-loop supply chain network. The estimated number of EoL ships is used as an input in the model and then it is solved by a mixed-integer linear programming (MILP) model of the closed-loop supply chain network to minimise the total logistic costs. A discounted payback period formula is developed to calculate the length of time to recoup an investment based on the investment's discounted cash flows. Existing ship wrecking industry clusters in the Western region of India are used as the case study to apply the proposed model.FindingsThe MILP model has optimised the total logistics costs of the closed-loop supply network and ascertained the optimal number and location of remanufacturing for building EoL ships. The capital and variable costs required for establishing and operating remanufacturing centres are computed. To remanufacture 30 ships a year, the discounted payback period of this project is estimated to be less than two years.Practical implicationsShip manufacturing businesses are yet to re-manufacture EoL ships, given high upfront capital expenditure and operational challenges. This study provides management insights into the costs and benefits of EoL ship remanufacturing; thus, informing the decision-makers to make strategic operational decisions.Originality/valueThe design of an optimal close loop supply chain network coupled with a Bayesian network approach and discounted payback period formula for the collection and remanufacturing of EoL ships provides a new integrated perspective to ship manufacturing.

One of the most significant and value added End of Life (EoL) recovery strategy in the circular economy is remanufacturing which retains the form, functionality and performance of the assemblies and structures through recovery and restoration. In the marine industry, remanufacturing is still at its infancy however there is a huge potential in implementing remanufacturing. In safety-critical industry such as marine, designing products for remanufacturing has to be integrated with reliability and safety design aspects since products and assemblies are used in a long life cycle whilst subjected to harsh environmental conditions. This paper discusses issues on Design for Remanufacturing (DfRem) and provides an insight into how remanufacturing plays a significant role in enhancing reliability and safety during the extended life cycle of marine products and assemblies, thus enabling the marine industry to contribute significantly towards the circular economy.
