There is a strong political focus on moving cargo transportation from trucks to ships to reduce environmental emissions and road congestion. We study how the introduction of a future generation of autonomous ships can be utilized in maritime transportation systems to become more cost-efficient, and...

The hydroelastic behavior of propellers has been a recurring topic in ship propulsion; seen at time as a possible cause for failures of propulsive systems and some other times as an opportunity for improving the performances of propellers as a noise and vibration sources, it often suffered from a...

This paper deals with dynamic modelling and numerical simulations of a Surface Effect Ship (SES) with split cushion. Traditionally, a SES is a catamaran with front and aft seals equipped with lift fans that could fill an air cushion with pressurized air to lift up to 90 % weight of the vehicle. A...

This paper presents a comparative study of mechanical properties of biodegradable PBSAT (polybutylene succinate co-adipate-co-terephthalate) and conventional polyamide (PA) gillnets used in Norwegian fisheries. Field tests were performed to simulate abandoned, lost, or otherwise discarded fishing...

Lumpfish (Cyclopterus lumpus L.) in Norway is currently produced in traditional flow-through systems (FTS). Hatcheries frequently show signs of bacterial infections, unstable microbial communities in the rearing water and varying mortality. Recirculating aquaculture systems (RAS) is proposed to...

The main objective of this study is to develop a new protocol for bench-scale dispersant effectiveness testing adapted for subsea dispersants injection (SSDI). The new approach includes turbulence conditions, dispersant injection techniques and quantification of effectiveness, more representative...

Limited experimental and field data are available describing oil droplet formation from subsea releases at high pressure. There are also analytical challenges quantifying oil droplets over a wide size and concentrations range at high pressure. This study quantified oil droplets released from an...

Results of the fluid-structure co-simulations that were carried out as part of the FleksProp project are presented. The FleksProp project aims to establish better design procedures that take into account the hydroelastic behavior of marine propellers and thrusters. Part of the project is...

Finding the optimal fleet composition under uncertainties is crucial for the economic success of a business. This paper presents the Fleet Efficiency Factor, a decision support tool for fleet size and mix problems and fleet composition problems. The method is based on a particle swarm optimisation...

Many marine species ingest microplastic (MP), exhibiting extended periods of MP gut retention in some cases. Organic pollutants associated with MP may present an alternative exposure route for these chemicals to marine species. However, the effect of PAH sorption to MP on PAH bioavailability remains...

Northwards flowing Atlantic waters transport heat, nutrients, and organic carbon in the form of zooplankton into the eastern Greenland Sea and Fram Strait. Less is known of the contribution of phytoplankton advection in this current, the Atlantic Water Inflow (AWI) spanning from the North Atlantic...
