- In response to increasing information and communication systems on board ships, we recognise that communication within the she ship and between ships or ship-shore must be optimised. With fewer crew members on-board coordination is more important and the voyage management can be optimised for demands on for example energy efficiency, safety and on-board resource use and availability (e.g. crew members). A pilot study shows that large interactive surfaces have promise for supporting the coordination of the voyage planning and execution.

- Previous studies have discovered that the tacit but indispensable “ship sense” from seafarers is intensively involved in creating and maintaining “harmony” to assure the safety. The concept of “harmony” reveals the continuous balanced effect by tuning the ship to the dynamic environment under different situations that ship handlers strive for. While the notions of ship sense and harmony is originally created for onboard ship maneuvering, this paper extends it to the domain of shore-based control centers for unmanned ship handling from the perspective of human factors. With the loss of direct ship-sense, the harmony is also lost. This paper analyzes the challenges from having the operator onboard to onshore during ship maneuvering and explores the changing aspects of human factors we need to focus on, in order to facilitate shore-based ship-handlers to regain the harmony. The EU project Maritime Unmanned Ship though Intelligence in Networks (MUNIN) provides the context to conduct the focus group interview of participants with seagoing experience. The shifted human factors in shore-based unmanned ship handling are discussed. The results highlight several differential aspects in human factors that should be considered, such as situation awareness. It provides keys to design shore-based control center for remote monitoring and control in accordance with user-centered design principles.

Exposure to wood smoke particles leads to inflammation, disrupted proliferation and damage to cellular structures in a human first trimester trophoblast cell line

Tidskriftsartikel (refereegranskat)abstract
- The ongoing transition to renewable fuel sources has led to increased use of wood and other biomass fuels. The physiochemical characteristics of biomass combustion derived aerosols depends on appliances, fuel and operation procedures, and particles generated during incomplete combustion are linked to toxicity. Frequent indoor wood burning is related to severe health problems such as negative effects on airways and inflammation, as well as chronic hypoxia and pathological changes in placentas, adverse pregnancy outcome, preterm delivery and increased risk of preeclampsia. The presence of combustion-derived black carbon particles at both the maternal and fetal side of placentas suggests that particles can reach the fetus. Air pollution particles have also been shown to inhibit trophoblast migration and invasion, which are vital functions for the development of the placenta during the first trimester. In this study we exposed a placental first trimester trophoblast cell line to wood smoke particles emitted under Nominal Burn rate (NB) or High Burn rate (HB). The particles were visible inside exposed cells and localized to the mitochondria, causing ultrastructural changes in mitochondria and endoplasmic reticulum. Exposed cells showed decreased secretion of the pregnancy marker human chorionic gonadotropin, increased secretion of IL-6, disrupted membrane integrity, disrupted proliferation and contained specific polycyclic aromatic hydrocarbons (PAHs) from the particles. Taken together, these results suggest that wood smoke particles can enter trophoblasts and have detrimental effects early in pregnancy by disrupting critical trophoblast functions needed for normal placenta development and function. This could contribute to the underlying mechanisms leading to pregnancy complications such as miscarriage, premature birth, preeclampsia and/or fetal growth restriction. This study support the general recommendation that more efficient combustion technologies and burning practices should be adopted to reduce some of the toxicity generated during wood burning.

Towards holistic performance-based conceptual design of Arctic cargo ships
- 2018

Ingår i: Marine Design XIII. ; 2, s. 831-839

Konferensbidrag (refereegranskat)abstract
- We present an extension of an earlier presented framework for use in the conceptual design of Arctic cargo ships. To enable a holistic approach, the framework integrates a wide range of performance assessment tools and methods namely (a) Discrete Event Simulation (DES) based Monte Carlo simulations, (b) system thinking, and (c) empirical data analysis. The thinking behind the framework is demonstrated by discussing how it could be applied to assess the design impact of four specific technologies: (1) a ‘Biomimetic anti-icing coating’, (2) a ‘Safe Arctic bridge’ using augmented reality (AR) technology for improved situation awareness,(3) a ‘Arctic voyage planning tool’ using Big data analysis, and (4) the use of low flash point fuels’ in the Arctic.
