Underwater sound mapping is increasingly being used as a tool for monitoring and managing noise pollution from shipping in the marine environment. Sound maps typically rely on tracking data from the Automated Information System (AIS), but information available from AIS is limited and not easily related to vessel noise emissions. Thus, robust...

The maritime sector is facing a major challenge. While a globally growing economy leads to more demand for transport of goods, the goals from the Paris climate agreement and the subsequent agreement in IMO require a 50% reduction of CO2- emissions from maritime transport by 2050. Several parties are working on the development of new fuel types...

The objective of Work Package 5 - System design for short sea shipping is to apply the theoretical findings from the previous work packages into practical ship designs and to evaluate these designs with regard to safety, technical and economic feasibility in view of future pilot projects. The market-segment of shipping that is known as “short...

The maritime sector is facing a major challenge. Whilst a globally growing economy leads to greater demand for the transport of goods, the goals from the Paris Climate Agreement and the subsequent agreement of the IMO requires a 50% reduction of CO2-emissions from maritime transport by 2050 compared to the level of 2008. Several stakeholders ...

The atmospheric aerosol has a large influence on global climate through its ability of scattering and absorbing electromagnetic radiation, which affect the Earth's radiative balance. Characteristics, such as size distribution, chemical composition and hygroscopic properties are important for improving global climate model projections of natural...

The maritime sector is currently facing a serious challenge of reducing emissions to meet the strict international and national emission regulations. In response to this challenge, the industry is initiating several research initiatives focused towards employment of alternative fuels in marine internal combustion engines. One of the promising...

The coastal aerosol represents a complex mixing between sea spray aerosols locally generated at the sea surface and a component generated by natural and/or anthropogenic sources on the nearby land. The aim of this paper is to study the atmospheric concentrations of carbonaceous compounds as measured in the coastal zone of the Northern Adriatic...

Increasing pressure on shipping to contribute to reduce Greenhouse Gas emissions is changing the landscape for marine fuels. In this Green Maritime Methanol project, the feasibility of application of methanol for the maritime sector are being elaborated, with a focus on short sea shipping. As part of this project, this report compares the Total...

The poor access to data on the marine environment is a handicap to government decision-making, a barrier to scientific understanding and an obstacle to economic growth. In this light, the European Commission initiated the European Marine Observation and Data Network (EMODnet) in 2009 to assemble and disseminate hitherto dispersed marine data. In...

Comparisons are made of sound pressure and particle acceleration predicted by two methods in the vicinity of two arrays of marine-seismic airguns. Data describing the array properties and the environmental conditions are taken from test cases designed to facilitate intermodel comparison.The two propagation approaches, one based on method of...

Based on the re-interpretation of well (log) data this study shows that the Våle Formation was deposited over large areas (> 100 km) in the southern central North Sea Basin (offshore Netherlands). Up to now, the Våle Formation (and the lateral equivalent Maureen Formation) were only described in the nearby offshore Denmark, Norway and UK. In the...

Offshore activity in low-temperature areas requires the use of analysis methods that are capable of reliably predicting cleavage (brittle) fracture of ferritic steels in order to guarantee the structural integrity during service. Cleavage fracture is controlled by physical events at different size scales and is influenced by the multiple...

To understand the consequences of underwater noise exposure for cetaceans, there is a need for assessments of behavioural responses over increased spatial and temporal scales. Bottom-moored acoustic recorders and satellite tags provide such long-term and large spatial coverage of behaviour compared to short-duration acoustic-recording tags....

Physical load experienced by dismounted military has already been studied extensively. Few studies, however, have focused on the cognitive load of dismounted soldiers during military operations in the field. In this project, a cognitive task analysis (CTA) was performed to study the cognitive workload of a troop commander during troop hasty...

Crewmembers are exposed to high work pressure. Pressure on freight tariffs motivates cost reduction in manning and maintenance, whilst societal developments show decreasing tolerances towards incidents. In conjunction with the developments towards autonomous shipping, the need for continuous and unmanned inspection increases. Considerable...

Multiphase conditions can lead to high vibration in flexible pipe systems due to high dynamic flow induced forces. To better model the dynamic forces, large scale 6” air-water, near-atmospheric experiments have been done with different bend radii and upstream configurations. This paper gives an overview of the obtained results with respect to...

Climate and tectonics effect the fluvial evolution of the Mediterranean Mut basin. The basin contains a river terrace staircase of 16 levels (T16-T1) ranging from 365 to 10A m above the current Goksu River in its middle and lower sections. These river terraces records tectonic uplift in the Mut basin. Optically stimulated luminescence (OSL)...

We quantify the impact of atmospheric transport and limited marine boundary layer sampling on changes in global and regional methane burdens estimate using tracer transport model simulations with annually repeating methane emissions and sinks but varying atmospheric transport patterns. We find the 1σ error due to this transport and sampling...
