Decision Support Tool for Maritime Decarbonisation

With the current focus on climate change, the shipping industry is forced to decarbonise its fleet. The need for decarbonisation is not only fuelled by the aspirations of the sector but also by laws and regulations from countries and organisations. As these laws are gradually tightening and there is not one clear technical or operational...

A review of operations and maintenance modelling with considerations for novel wind turbine concepts

New wind turbine technologies and designs are being explored in order to reduce the cost of energy from offshore wind farms. Two potential routes to a lower cost of energy are the X- Rotor Concept (XRC) and Multi-Rotor System (MRS) turbines. A key cost saving for both Novel concepts included in this paper is operation and maintenance (O&M...

Piece small jacket removal vs. single lift jacket removal: Development of a method for deciding on optimal jacket removal methods

Marine contractors as Heerema Marine Contractors (HMC) have made decommissioning part of their core business. Being the owner of two of the largest semi-submersible crane vessels (SSCVs), the choice for single lift jacket removal is straightforward. However, jackets in the Northern North Sea have a weight and height exceeding the crane capacity...

Increasing the Effectiveness of the Capacity Usage at Rolling Stock Service Locations

Passengers often complain about dirty trains indicating the relevance of interior cleaning of rolling stock (RS). Servicing tasks (i.e. interior and exterior cleaning and smaller technical checks) are executed on a daily basis at service locations (SLs). Currently, due to train operations during daytime, the current focus lies on night servicing...

A decision support model for analysing the reuse potential of hollow-core slab floor components

This thesis ‘A decision support model for analysing the reuse potential of hollow-core slab floor components’ describes the development of a decision support model to investigate the reuse potential of a structural building component. For this research, the hollow-core slab floor component is chosen as the structural building component to be...

Evaluating Multi-Disease Interventions

Policymakers who work in the public health sector may rely on the help of quantitative models to support their choice of control strategy against a particular infectious disease. While policymakers have a large number of decision support models to choose from, hardly any of these tools are used to design an intervention strategy that can work...

Improve the future, renovate the past: A research on improving the balance between cultural value, sustainability, and costs in industrial heritage renovation projects

Industrial heritage buildings are a significant part of the total building stock. Most of these buildings have a higher energy consumption. This means that it will have a positive impact on the climate when these buildings are renovated. Next to that, the vacancy of heritage buildings, especially industrial heritage, is increasing. In the early...

A decision support model for repair scheduling of defect train sets

Defects that occur on train sets have to be repaired in a repair location and this has consequences on the transportation network. This paper proposes a decision support model that is developed for optimising the decisions of when and where to repair that defect train set. In practice, there is no clear overview of the effects of such decisions...

Blueprint for intervention: A Decision Support Model for transformation of Vacant Office Buildings in Amsterdam

GOAL – The goal of this research is to examine the possibility of a decision support model concerning intervention strategies of vacant office buildings in Amsterdam. This quick scan results in the best future function and intervention for a specific vacant office building. This DSM is based on the market, the location and the building analyses...

Improving the economic performance of AkzoNobel's EVB plant

AkzoNobel Energie Voorzienings Bedrijf (EVB – Energy Supply Company) is located at the Botlek business park in Rotterdam. EVB produces and supplies energy and utilities to other production plants at the Botlek site. Due to the intertwined value chain and reuse of each other’s residual and waste products, the situation at the Botlek is...

Selecting the Most Cost-Efficient Air Emission Reduction Technology for a ship under IMO Compliance: A Decision Support Model Approach

Decision support model that determines which air emission reduction technologies can be installed on a ship, such that the ship will comply with IMO ANNEX VI Regulation 13 (NOx regulation). Consecutively, the model will determine which remaining air emission reduction technology is the cheapest so a long term cost-efficient decision can be taken.
