Abstract
Purpose
This paper proposes a heuristic, data-driven approach to the rapid performance evaluation of periodic maintenance on complex production plants. Through grouping, maintenance interval (MI)-based evaluation and performance assessment, potential nonvalue-adding maintenance elements can be identified in the current maintenance structure. The framework reduces management complexity and supports the decision-making process for further maintenance improvement.
Design/methodology/approach
The evaluation framework follows a prescriptive research approach. The framework is structured in three steps, which are further illustrated in the case study. The case study utilizes real-life data to verify the feasibility and effectiveness of the proposed framework.
Findings
Through a case study conducted on 9,538 pieces of equipment from eight offshore oil and gas production platforms, the results show considerable potential for maintenance performance improvement, including up to a 23% reduction in periodic maintenance hours.
Research limitations/implications
The problem of performance evaluation under limited data availability has barely been addressed in the literature on the plant level. The proposed framework aims to provide a quantitative approach to reducing the structural complexity of the periodic maintenance evaluation process and can help maintenance professionals prioritize the focus on maintenance improvement among current strategies.
Originality/value
The proposed framework is especially suitable for initial performance assessment in systems with a complex structure, limited maintenance records and imperfect data, as it reduces management complexity and supports the decision-making process for further maintenance improvement. A similar application has not been identified in the literature.

Abstract
Purpose
The purpose of this paper is to describe the different design approaches architects take towards the adaptive reuse of small-scale shipyards. Thereby giving a proposition for future projects by giving insight in how others preceded and showcasing different possibilities.
Design/methodology/approach
The research is based on a literary review in combination with a case study, following one main question: What architectural approaches do architects employ in redesigning nineteenth- and twentieth century dockyards in Northern Europe and how do these approaches consider the history of building and context? First, this paper researches the history of adaptive reuse. Additionally, the historical and cultural context of shipyards is researched. Finally, a case study is done linking theory with practice. Selected cases are: Kromhout shipyard in Amsterdam, Verftet Ny-Hellesund in Ny-Hellesund and the Maritime Museum in Helsingør.
Findings
Four approaches to adaptive re-use were distinguished in the cases: differentiation, continuation, cultivation and optimisation. Each has its own implications for the design and the chosen approach is ultimately related to the important heritage values of each individual shipyard. Heritage professionals proved to have a great say, in the early stages of the adaptation process, in which the adaptive reuse approach was chosen.
Research limitations/implications
This comparative research enables an in-depth analysis and comparison and thorough qualitative understanding. It however limits the insight in the representativeness of these cases.
Originality/value
This paper compares the adaptive reuse of small-scale shipyards in an international perspective. It offers insight into the patterns, principles and context of the architectural reuse of this underexposed industrial heritage.
