Marine Monitoring to Maximise the Performance of Marine Machinery
Considering the cost of putting to sea, it is well worth investing in vibration monitoring equipment that can help engineers to protect and maximise the performance of marine machinery. Here, we discuss the challenges facing engineers and offers advice on how to successfully install and use vibration sensing equipment on marine vessels. As machinery has become more complex and mankind has ...

Application of multivariate methods in the monitoring of marine environment: simultaneous determination of bromide, bicarbonate, nitrate and sulphide in seawater by ultraviolet spectroscopy
In this paper we present a new ultraviolet (UV) spectroscopic method for the simultaneous and reagentless determination of bromide, bicarbonate, nitrate and sulphide ions in artificial seawater solutions, applicable to the monitoring of the marine environment. We collected the UV spectra of artificial seawater samples with salinity between 8 and 45 psu, having known concentrations of these ...

Advantages of Underwater drone Development
First of all, the traditional underwater operation, manual operation are very complex, and the personal safety can not be fully guaranteed from its development background. Moreover, with the increasingly extensive human marine activities, the development of various industries on water and underwater is accelerating. The demand for underwater UAVs will continue to rise in the future, which is the ...

Marine Monitoring of Emissions of Air Pollutants
Many of us who are not in the marine shipping business probably think of vessels as practical means of transportation, or, when it comes to cruising ships, a place to spend your vacation. However, not all of us realize that large ships also are floating large power plants, with all aspects that come with power plants including potential contribution to air pollution. The environmental aspects of ...

Environmental problems in Russia affecting the Black and Baltic Seas
This paper addresses problems of marine environment protection in Russia, with an emphasis on the legislative and institutional basis for protecting the seas from oil pollution. The status of the Black and Baltic Seas is described, together with the relevant technical, organisational, and economic elements. As an example of a comprehensive approach for tackling the problems under consideration, ...

Marine Hydrophone Arrays
A hydrophone array comprises several hydrophones strategically placed in known locations, such as in a line on the seafloor, moored vertically in the water column, or towed horizontally behind a vessel. When sound from a distant source, like a submarine, reaches the array, each hydrophone detects it at slightly different times, depending on the sound’s direction. This time difference, ...

Future Development Trend of Underwater Drone
1. Technological innovation will be the eternal theme As a highly technology-intensive and systematic project, underwater vehicle mainly includes six technologies: simulation, intelligent control, underwater target detection and recognition, underwater navigation (positioning), communication and energy system. Compared with developed countries, there is still a big gap in the research ...

Measurement of TOC in High-Salt Sample
The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

An empirically tractable model of optimal oil spills prevention in Russian sea harbours
Based on previous theoretical work by Gottinger (1997, 1998), we propose a simple model of optimal monitoring of oil-related activities in harbour areas that is suitable for empirical estimation within the Russian— Ukrainian context, in spite of the poor availability of data in these countries. Specifically, the model indicates how to best allocate at the steady state a given monitoring budget ...

Global monitoring of marine fuels and machine condition
The “Shipping, Marine and Ports World” has published in its Dec 2012-Jan 2013 issue, an article written by Dr. Helene Gutman (CTO, Xenemetrix Ltd.). The article presents: The use of EDXRF analytical method systems that enable fleet management to optimize bunkering and machine maintenance. The new sulfur emission regulations for ocean going vessels present a serious challenge for the ...

Real-Time Monitoring of the Endangered Northern Right Whale - Case Study
BACKGROUND In 2006, Excelerate Energy requested a permit in order for its Deepwater port, Northeast Gateway, to be connected to the New England gas grid through a subsea interconnect. The permit was required because ships entering the port delivering LNG introduced a higher risk of vessels striking mammals, in particular the endangered Northern Right Whale. CHALLENGES In the face of energetic ...

New approaches for monitoring the marine environment: the case of antifouling paints
Protection of ships hulls against biofouling has been a problem since man began sailing the seas. The most common protections are specially produced antifouling paints. These paints could be broadly classified in three main groups, or generations, depending on the technology applied: first generation copper-based, second generation organotin-based, and the new, third generation, organotin-free ...

Recreational Water Contact and Illness in Mission Bay, California
Untitled Document Fecal indicator bacteria are routinely monitored at marine recreational bathing beaches to assess the public health risk of contracting swimming-related illness. There have been numerous epidemiology studies that demonstrated the relationship of indicator bacteria to health risk, but they have been mostly conducted on beaches impacted by point ...

Integrated maritime policy for the EU working document III
One of the elements of the integrated Maritime Policy for the European Union1 that the Commission is pursuing is enhanced interoperability and integration between existing maritime surveillance and monitoring systems, across the different maritime sectors. As a first step it is necessary to have better awareness of the present situation. This report tries to summarise some information on existing ...

Efficient Method For Slipway Winch Calculation
Calculating the parameters and specifications for a slipway winch requires a systematic approach and careful consideration of various factors to ensure efficiency, safety, and optimal performance. A slipway winch is a critical component in marine operations for launching and retrieving boats, yachts, and other watercraft. Efficient calculation methods are essential for determining the appropriate ...

Matrix Gemini LIMS at work in the Nuclear Industry
Bradwell nuclear power station is located on the Dengie peninsula at the mouth of the River Blackwater in Essex. Construction of Bradwell power station began in December 1957 and electricity generation started in 1962. It had two Magnox reactors producing 242 Megawatts of electricity. It could supply enough electricity to meet the combined needs of three towns the size of Chelmsford, Colchester ...

3D Offshore Imaging for Seawater Intake for Desalination Plants - Case Study
AGI’s Multi-Electrode Switch Box is an accessory to the SuperSting Wi-Fi. It allows the SuperSting Wi-Fi to automatically control and switch passive electrodes connected by a passive multi-electrode cable for automatic data acquisition in 2D, 3D, and 4D surveys. The rugged and sealed design makes it ideal for harsh environments like sub-surface, marine and borehole measurements, ...

Quantification of pharmaceuticals, personal care products, and perfluoroalkyl substances in the marine sediments of Puget Sound, Washington, USA
Concentrations of 119 pharmaceuticals and personal care products (PPCPs) and 13 perfluoroalkyl substances (PFASs) in marine sediments measured throughout Puget Sound (n = 10) and Bellingham Bay (n = 30), Washington, USA, are reported. These data are among the first measurements of PPCPs and PFASs in marine sediments from the Pacific Northwest and provide a comparison to previous measurements ...

The threat of pellets and other microplastics in the ecosystem
The recent accident in Galicia, where thousands of plastic pellets were dumped into the sea, has served as a stark reminder of the serious problem of microplastic pollution. More than an isolated incident, this incident invites us to reflect on the environmental repercussions of these tiny elements, their impact on marine life and the measures we can take to mitigate their presence in our oceans. ...
