One of the latest trends in the green movement is discovering the many types of renewable energy. The ocean provides a wealth of opportunities for creating energy from natural resources. These are grouped together in the category of marine renewable energy. Energy carried via ocean temperature fluctuations, salinity, waves and tides create a form of kinetic energy. The goal for researchers is to determine how to harness this energy for electricity sources applicable to industries, homes and transportation systems. In addition to uncovering new ways to generate energy, here at Stewart Technology Associates we provide the capabilities for measuring these energy sources, such as via mooring analysis.

Wave Power

Wind used to form waves is created by the temperatures of the sun via solar energy. When wind interacts with the ocean’s surface, waves are generated. In terms of wave power, a wave that is found at between 30 and 60 degrees latitude, for both the northern and southern hemisphere, is most beneficial. For those researchers interested in harnessing wave power, various approaches must be considered. The four most popular approaches to this research include analysis of surface attenuators, overtopping devices, point absorber buoys, and oscillating water columns.

Tidal Power

As with wave power, tidal power also involves the movement of water. However, with tidal power the energy is generated through hydroelectric power. For those studying tidal power possibilities, there are three ways that tidal power is produced. These include dynamic tidal power, tidal stream power and tidal barrage power.

Marine Current Power

When the ocean fluctuates in salinity, temperature, wind and bathymetry, there is a fluctuation in marine currents. This form of marine renewable energy is most applicable to energy extraction methods, such as the powering of turbines. One issue that can affect the rate of marine current power is the presence of marine organisms. As a result, this form of power must be applied at distances far offshore, which involves lengthy power cables for its transmission.

Ocean Thermal Energy

Water temperatures vary according to its depths. For tropical waters, this difference in temperature is the greatest degree, which generates ocean thermal energy. This energy is most suitable for vaporization used for production of desalinized water or electrical generation on a localized scale.

Osmotic Power

Reverse osmosis is useful for converting salt water to fresh water. In the process, salinity gradient energy is created at the stage of conversion. While this is a new technology and form of marine renewable energy that is on the cusp of understanding by researchers, there is stronger possibility of its effectiveness, as being noted in Europe by researchers of the Netherlands and Norway. Finding ways to make renewable energy from the ocean is hopeful thanks to modernized technology and equipment. Contact Stewart Technology Associates today to learn more.

Use the program to analyze moorings including oceanographic, aquaculture, spread and jetty mooring systems. Additionally, installation analysis for anchor/mooring deployment and riser installation is an ideal treatment for the use of this program. You can take this software and determine offshore lift dynamics, in addition to cable lay dynamics, to make the most of your time with offshore marine systems analysis.

Other applications that you can use this system for include through-splash zone deployment, seabed plough deployment, and J-Tube pull-in. Buoy systems are a breeze to analysis, whether you are working with metocean, SPAR or CALM buoys. If you are operating on defense systems, such as helicopter landing systems or minesweeping studies, or your company works with renewable energy via floating wind turbines or wave power systems, take the OrcaFlex system to task on your next assignment.

Multiple Capabilities for Performance

In addition to serving as a general provider of data analysis for nearly every offshore marine function known to man, this software will also function successfully as a library. Store your data within the program for future analysis, if desired, or to use for testing purposes. You can also use the software via automation to render your valuable time on other projects. Integration with 3rd party software is fully available with this offshore marine systems software program.

Who Can Use Offshore Marine Systems Software

As you can see by the lengthy applications for this program, there is a limitless number of businesses in the offshore marine sector that can benefit from this software. For instance, those functioning in ocean engineering, compliant marine renewables, aquaculture and seismic can directly relate to the analysis options provided with the program.

What is needed to Access the Software

In order to begin using this software, you will need a computer that has at least Windows Vista or Windows 7 platforms. However, it is fully capable of running using Windows 8, and 32- and 64-bit versions are supported. You will need to check your screen resolution, as there is the minimum requirement of 1024 x 768. Ideally your setup will include a high degree of memory performance due to the simulation and intensity of this program. Opt for a minimum of 4GB of memory for best results, and multi-core systems are optimal. To learn more about this type of offshore marine systems software, contact Stewart Technology Associates.

When it comes to maintaining your dock and structures, there is no doubt you take the process seriously. There’s a lot to think about, too, including how you will maintain any necessary codes or how you will ensure that your marine structures are safe and secure for any type of application. It can be overwhelming especially when you do not have all of the information you need. With the help of our mooring analysis team, though, you’ll gain the information you need. No matter who you turn to for this service, it is important to choose a company that offers key features like those listed below.

#1: Turn to an expert with advanced skills

According to Wikipedia.org, mooring is a term used to describe the permanent structure that a vessel is secured against. That may be all you know about it. However, you’ll want to hire a team that’s advanced in their skills. You want a company with ample experience that you can rely on for any of your questions or needs.

#2: Technology makes a big difference

In mooring analysis, it is essential to turn to a professional that has ample experience but also the right technology. The right marine technology gives you the information and guidance you need when determining if your structure is safe and reliable. It is important choose services that use the most up to date technology for the industry so you get the best information possible.

#3: Choose a company that specializes in your specific need

It is also important to consider the type of services you need. There is a difference in the process and experience of the professionals in the various types of moors present. For example, you want a professional who can handle jetty moorings or harbor moorings. You may need one that works with large ships or those that have the advanced technology to handle small areas. It is a good idea to also discuss marine renewable energy and the company’s ability to meet your needs in that area.
