Combining design and strategy in offshore shipping
Strøm, Morten Andreas; Rehn, Carl Fredrik; Pettersen, Sigurd Solheim; Erikstad, Stein Ove; Asbjørnslett, Bjørn Egil; Brett, Per Olaf (Chapter, 2018)This paper presents the design-strategy planning (DSP) procedure as a framework that integrates life cycle strategies of a ship into the early stages of the design process. We argue that understanding strategic, tactical, ... -
Comparing Offshore Support Vessel Production Times between Different Offshoring Strategies Practiced at Norwegian Shipyards
Semini, Marco; Brett, Per Olaf; Strandhagen, Jan Ola; Vatn, Jørn (Peer reviewed; Journal article, 2022)To save costs and build competitiveness, Norwegian shipyards usually offshore some of the processes required to produce a ship, especially steel-related tasks, i.e., they have them carried out in a country with lower factor ... -
Considering Alternative Strategies to Improve Synergies between Shipbroker and Ship Designer in Upstream Shipbuilding Activities
Sjåvåg, Ludvik (Master thesis, 2022)Denne masteroppgaven analyserer hvordan vi kan identifisere en mer effektiv interaksjon mellom skipsmeglere og skipsdesignere i oppstrøms skipsbyggingsaktiviteter. Vi foreslår fire forskningsspørsmål som legger til grunn ... -
Design for resilience: Using latent capabilities to handle disruptions facing marine systems
Pettersen, Sigurd Solheim; Asbjørnslett, Bjørn Egil; Erikstad, Stein Ove; Brett, Per Olaf (Chapter, 2018)This paper explores how the resilience of marine systems against disturbances can be improved by considering latent capabilities. With resilience is meant the ability of a system to recover and return to an acceptable, ... -
Designing a marine systems design specialization track at NTNU
Erikstad, Stein Ove; Brett, Per Olaf; Lagemann, Benjamin (Journal article; Peer reviewed, 2024)In this paper we describe and discuss the current and future MSc specialization programme in marine systems design at the Norwegian University for Science and Technology (NTNU). We follow the structure of a design process. ... -
Early Marine Systems' Design - Cracking the wicked problem - The case of a novel biomass harvesting vessel
Brett, Per Olaf; Garcia Agis, Jose Jorge; Lagemann, Benjamin (Journal article; Peer reviewed, 2024)Several IMDC contributions have argued for a better approach to capture stakeholders' expectations in vessel newbuilding projects' execution. The appropriate processes of requirements elucidation are, however, often forgotten ... -
Early Stage Decisions in Marine Systems Design for Deep-Sea Mining
Solheim, Astrid Vamråk; Pettersen, Sigurd Solheim; Agis, Jose Jorge Garcia; Brett, Per Olaf; Asbjørnslett, Bjørn Egil; Erikstad, Stein Ove; Ellefmo, Steinar Løve (Peer reviewed; Journal article, 2022)This article studies the prospects for deep seabed mining as a future viable maritime industry, and discuss the commercial, operational, and technical viability of deep seabed mining. By the use of a business development ... -
Effectiveness in Decision-Making in Ship Design under Uncertainty
Agis, Jose Jorge Garcia (Doctoral theses at NTNU;2020:53, Doctoral thesis, 2020)The objective of this thesis is to develop a better understanding of how to carry out more effective conceptual ship design processes. Under the premise that uncertainty influences the effectiveness of the decision-making ... -
Engineering Change Management in the Engineer-to- Order Production Environment
Iakymenko, Natalia (Doctoral theses at NTNU;2021:381, Doctoral thesis, 2021)Engineer-to-order (ETO) is a production environment where a product is designed, engineered, and produced based on a customer order. Companies operating in the ETO production environment create complex products tailored ... -
Exploring the performance of conceptual offshore production systems for deep-sea mining
Solheim, Astrid Vamråk (Doctoral theses at NTNU;2023:176, Doctoral thesis, 2023)Offshore production systems are required to support the extraction, lifting, and shipment of deep-seabed minerals. Increasing the knowledge about such novel systems is important to identify constrained parameters and ... -
Handling Ship Design Complexity to Enhance Competitiveness in Ship Design
Ebrahimi, Ali (Doctoral theses at NTNU;2021:92, Doctoral thesis, 2021)Ship design is inherently complex. In the literature, typically, complexity is associated with increased cost and requires more advanced tools, better procedures, expertise, and man-resources to deal with it. In the design ... -
