Study of the dispersion/settling of oil–mineral–aggregates using particle tracking model and assessment of their potential risks
A random walk particle tracking model was used to simulate the motions of oil–mineral–aggregates (OMAs) under hydrodynamic conditions involving wave–induced velocities, random velocities due to turbulence, and the settling velocity due to gravity. Wave–induced and settling velocities for OMAs determined from the application of Stokes's theory and empirical equations derived from experimental data ...

A dynamic model of optimal reduction of marine oil pollution
This paper proposes a system of dynamic models to describe the interactive behaviour of different agents (polluters, inspectors, and a principal pollution control agency) involved in the processes of marine oil pollution and of its prevention and purification, under some realistic assumptions. In particular, short- and long-term economic responses of polluters to monitoring efforts, as well as ...

Trans-boundary marine oil pollution and its international legal aspects
Marine pollution control is a sensitive topic, which has gained importance recently due to crude oil spills which in turn has led to many recent international legal developments. This paper examines the effectiveness of international marine laws in imputing liability and calculating damages where more than one nation is affected. The main international agreements covering the international marine ...

Heat Stress
Standards Employer Responsibilities under the OSHA General Duty Clause As per the Occupational Safety and Health Act of 1970, Section 5(a)(1) – known as the General Duty Clause – employers are obligated to furnish a workplace for their employees that is “free from recognized hazards that are causing or likely to cause death or serious harm to employees.” Courts have ...

DESMI Lifts Green Ship Business Case
New rules call for fresh approach It’s hardly news that the shipping industry is mobilising to meet the demands of wave after wave of new environmental regulations. From the IMO’s ballast water management legislation to EEDI (the Energy Efficiency Design Index for new ships) and SEEMP (Ship Energy Efficiency Management Plan), shipowners need to be ready to drastically cut energy ...

Stochastic models of oil spill processes
This paper models the occurrence of an environmental accident as a stochastic event. In particular, the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and size of spills. It is shown that both the time distribution of different types of oil spill and ...

Desorption kinetics of naphthalene from sediment particles: batch and stepwise desorption approach
We investigated three major parameters in simulating desorption behaviours: the pre-contamination period, dilution by clean water mass (dilution ratio) and the length of the time interval between dilutions, in both batch and stepwise desorption experiments using particles pre-contaminated with a polycyclic aromatic hydrocarbon, naphthalene (NAPH). We found that the dilution ratio plays a major ...

Understand the location very well before you purchase any oil spill response equipment
I love sports, football, tennis, surfing, ping pong, etc. and I always related that to the fact that I was very conscious in relation to the environment. In my eyes, sporty people have a higher tendency to protect nature. After finishing my studies in Finance and International Business, I ended up (as you do) working as an Oil & Gas Engineer in the UK with my very strong Peruvian accent. At ...

Empirical data and optimal monitoring policies: the case of four Russian sea harbours
In this paper, we describe the present state of empirical information about oil spills and oil monitoring activities in Russian harbours. We explain how we gathered, organised, and estimated the data needed to run the monitoring efforts optimisation model of Deissenberg et al. (2001). We present, analyse, and discuss the results of the optimisations carried out with this model on the basis of the ...

Rational application of chemicals in response to oil spills may reduce environmental damage
Oil spills, for example those due to tanker collisions and groundings or platform accidents, can have huge adverse impacts on marine systems. The impact of an oil spill at sea depends on a number of factors, such as spill volume, type of oil spilled, weather conditions, and proximity to environmentally, economically, or socially sensitive areas. Oil spilled at sea threatens marine organisms, ...
