Damage identification of a jacket support structure for offshore wind turbines
(Chapter, 2020)Offshore jacket structures are regarded as a suitable type of support structure for offshore wind turbines in immediate water depths. Because of the welded tubular members used and environmental conditions, offshore jackets ... -
Data-Driven Prediction of Vortex-Induced Vibration Response of Marine Risers Subjected to Three-Dimensional Current
(Chapter, 2019)Slender marine structures such as deep-water marine risers are subjected to currents and will normally experience Vortex Induced Vibrations (VIV), which can cause fast accumulation of fatigue damage. The ocean current is ... -
DC-DC Converter Control for Peak-Shaving in Shipboard DC Power System via Hybrid Control
(Chapter, 2020)For the stable operation of the shipboard hybrid DC power systems, the DC bus voltage should be controlled within the recommended range by the regulations. However, the challenge comes from the load variations, and it makes ... -
A Decentralized Droop-Based Power Management System for Ship Power Systems Using Hybrid Dynamical Systems Framework
(Chapter, 2023)In maritime transport, inspired by the automobile sector, autonomy is gaining traction in parallel with decarbonization. One of the numerous challenges in realizing fully autonomous operation in shipping is to design a ... -
Decision-Making Support for Reeled Pipeline Installation Using a Machine Learning Based Method
(Chapter, 2023)Installation of subsea pipelines used for transportation of hydrocarbons, water, or CO2, is carried out by ship-type installation vessels, which are highly sensitive to wave conditions. The prediction of installation loads ... -
Deep Sea Mining: Towards Conceptual Design for Underwater Transportation
(Chapter, 2020)This paper presents the first steps towards conceptual design for the underwater transportation of minerals from seabed to shore for deep sea mining (DSM). The methodology is based on conceptual design using a systematic ... -
Design against ship collisions in accordance with the new DNV RP C204
(Chapter, 2021)A new version of the DNV RP C204 standard for the design of offshore steel structures against accidental loads was released in 2019. The updated recommended practice made considerable changes on the design against ship ... -
Design and Analysis of a Braceless Steel 5-MW Semi-Submersible Wind Turbine
(Chapter; Peer reviewed, 2016)This paper introduces the design data and numerical analysis of a braceless steel semi-submersible wind turbine. The hull of the semi-submersible wind turbine is designed to support a reference 5-MW horizontal axis wind ... -
Design for resilience: Using latent capabilities to handle disruptions facing marine systems
(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 offshore tubular members against excessive local indentation under lateral impacts
(Chapter, 2017)Tubular members are widely used in offshore jacket and jack-up platforms. Such structures are often exposed to the risk of lateral impacts from service vessels and dropped objects. The impact responses can generally be ... -
Designing for System Value Sustainment using Interactive Epoch-Era Analysis: A Case Study from Commercial Offshore Ships
(Chapter, 2018)This paper applies the Interactive Epoch–Era Analysis (IEEA) framework on a case study from commercial offshore ship design, incorporating techniques from visual analytics such as interactive visualizations to gain insight ... -
Designing Resilience into Service Supply Chains: A Conceptual Methodology
(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
(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 ... -
Detection of plunging breaking waves based on machine learning
(Chapter, 2018)Plunging breaking waves that occur in the vicinity of offshore structures can lead to high impulsive slamming loads, which are significant for the structural loading. The occurrence of plunging breaking waves is usually ... -
Determination of Environmental Conditions Relevant for the Ultimate Limit State at an Exposed Aquaculture Location
(Chapter; Peer reviewed, 2017)Methods for determination of environmental conditions relevant for the ultimate limit state at an exposed aquaculture location are proposed. The considered location is in Frohavet, northwest of Trondheim, Norway. Wind, ... -
Determination of Hydrodynamic Parameters for Remotely Operated Vehicles
(Chapter; Peer reviewed, 2016)In this paper the hydrodynamic parameters that characterize the behaviour of a typical unmanned underwater vehicle are evaluated. A complete method for identifying these parameters is described. The method is developed to ... -
