Design for Operational Efficiency and HSE in Marine Operations between Floating Cage Collars and Service Vessels in the Aquaculture Industry
Hatlem, Odd Helge; Kvamme, Bettina Wickman (Master thesis, 2016)In the shadow of challenges with salmon lice, fish escapements and a desire of increased production growth, there have been less focus on the safety for the personnel on the fish farms and in the marine aquaculture operations. ... -
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, ... -
Design of an Offshore Standby Base for Remote Regions
Andresen, Even Sunde (Master thesis, 2013)In this Master?s thesis an optimization model for finding the optimal design of a standby base operating in remote regions is presented. The research and development within optimization of standby vessel design is limited. ... -
Design of Value Robust Container Ship Using the Responsive System Comparison Method
Dickens, Magnus (Master thesis, 2016)Traditionally the conceptual design phase of ships has focused on the technical analysis - the mapping from the design to the performance space. The performance of the vessel does not fully capture the value of the vessel, ... -
Design study of a vessel for the Arctic Scallop industry
Gundersen, Ingvild Wergeland (Master thesis, 2021)Målet med denne opgaven er å komme frem til design løsninger på et konseptuelt design nivå til et skip som skal benytte en ny type høstemetode for å høste Haneskjell. Dette er gjort med en systematisk tilnærming til ingeniør ... -
Design-Strategy Planning For Life Cycle Management of Engineering Systems
Strøm, Morten Andreas (Master thesis, 2017)The objective of this thesis is to contribute in developing frameworks and quantitative methods to support uncertainty management of engineering systems, with focus on offshore vessels. This thesis starts out with a ... -
Designing Feeder Routes in a Mother-Daughter Vessel System with Ship-to-Ship Cargo Transfer - A Combined Optimization-Simulation Approach
Nordheim, Hans Henrik (Master thesis, 2017)This thesis aims to develop decision support models for designing daughter vessel feeder routes for the mother-daughter vessel system Short Sea Pioneer. Short Sea Pioneer is a next generation short sea shipping system that ... -
Designing Resilience into Service Supply Chains: A Conceptual Methodology
Pettersen, Sigurd Solheim; Asbjørnslett, Bjørn Egil; Erikstad, Stein Ove (Chapter, 2018)This chapter presents a methodology for designing resilient service supply chains. The approach combines system design methods with methods from risk assessment. Service supply chains consist of multiple assets, cooperating ... -
Designing resilient fleets for maritime emergency response operations
Pettersen, Sigurd Solheim; Asbjørnslett, Bjørn Egil (Chapter, 2016)In this paper, we investigate the problem of designing resilience into a fleet for maritime emergency response operations. A broad set of events can trigger emergency response, requiring that a fleet of vessels for this ... -
Development of a Modular Design Process for Customised Closed Containment Systems
Skaret-Thoresen, Nora; Skaret-Thoresen, Rakel (Master thesis, 2019)Norge er verdens største produsent av atlantisk laks. Videre vekst er i tillegg ventet da regjeringen har uttalt en visjon om å femdoble produksjonsvolumet innen 2050, sammenlignet med 2010. Vekst kan for øvrig ikke ... -
