Procedure for Constructing an Offshore Wind Turbine Tower

The use of offshore wind power has grown rapidly, resulting in the continued advancements and construction of more wind turbines on the oceans. Offshore wind has been observed to provide the most reliable source of breeze to drive wind turbines for electric power generation. 

The construction begins with setting up an offshore wind turbine tower above which the turbine blades will be affixed. The installers can use several methods. Still, regardless of these countless options, a specific procedure must be followed to ensure the construction completes successfully. 

For that reason, this article will focus on outlining the most reliable procedure to ensure you get an offshore wind turbine tower installation. 

Select a Foundation 

Selecting a foundation for your tower is the first step you must follow. The type of foundation you choose determines the depth of the surrounding water. You will need to select a foundation on which the tower can firmly stand so that any collapse can be avoided to the maximum. 

For water bodies with shallow depths, it is recommended that you use a monopile. A steel tube is often driven into the seabed. It is also recommended by top installation specialists such as IQIP that the steel tube is forced into the seabed to half of its total length. This step ensures maximum strength to prevent the tower from collapsing due to strong storms and breezes. 

Installers use jackets for deeper water when setting up the foundation. Jackets are more like tripods, having three or four legs anchored to the ocean floor. The legs offer a wider surface area, thus lowering the tower’s center of gravity, hence, greater stability. 

Choose a Wind Turbine 

Modern offshore wind turbines are relatively larger than traditional ones. In most cases, the larger the turbine, the more turbine blades, and the greater the surface area for capturing the wind, the greater the electrical energy generated. 

The large size also means that you will need heavy-duty machinery to lift the turbine to the top of the tower. A pile upending tool will be significant in this operation as it ensures that you affix the turbine to the building effortlessly. 

You can also pick a boat for installing a turbine on the tower. It would help if you chose a boat with a crane affixed to it to help you reach the top of the tower. Also, consider the length of the crane because you probably do not want to strain to reach the top of the tower. Worse, you may even slip off and drown inside the ocean while attempting to make everything work to have the turbine affixed to the tower. 

Electrical Wiring

It is the final step, and it involves connecting the DC output of the offshore turbine system to the inverter and the power control unit. You will also need cables connected at the AC output of the inverter to the electricity grid, from where you can connect the system to the power supply. 

Do a final check on the electric connections to ensure everything is safe and works properly. Your installer should provide the necessary documentation, such as manuals, warranties, and maintenance information.

What Are the Different Types of Water Heaters That Exist Today?

Did you know that water heating accounts for as much as 20% of your household energy use? And that figure grows the longer you stay in that nice hot shower!

Of course, the types of water heaters you choose can also increase (or reduce) your that figure. Once upon a time, people just had a simple hot water tank heated by a fuel of some kind. Today, there’s a surprisingly extensive range of water heaters to choose from, and knowing which is best for your home can be daunting.

If you’re upgrading your current heater or choosing appliances for a new build, diving into the pros and cons of each machine is essential. Below, we explore it all. So read on!

What Is a Water Heater?

Before you can find the best water heater for your home, you need to understand what a water heater is and does!

Believe it or not, but the is right there in the name: a water heater is an appliance that heats the water in your home, which you then use to wash dishes, clean your body, and wash your clothes–among other activities.

Before the 1890s or so, Americans had to heat their water in an enormous metal bucket atop their wood-burning stoves. Then, they’d carry it over, bucket by bucket, to fill a bathtub in the kitchen.

Today, we’re far luckier–we have water heaters and indoor plumbing to do the job for us.

How a Water Heater Works

Now we’ve cleared that up, let’s explore how a residential water heater does what it does. While there are many types of water heaters (more on those later), they all work in similar ways.

First, water is fed into a tank or runs through a pipe. Then, the water is heated slowly (in the case of the tank) or rapidly (in the case of the pipe) until it reaches a pre-determined temperature. Then, when you turn on the hot tap anywhere in your home, the water leaves the tank or runs through the pipes, arriving in the sink or shower hot.

Water heaters mostly used to function on electricity, but now you can run water heaters on gas, solar, and even the hot air from your attic!

If you need a water heater replacement, that’s usually a plumber’s job. But, unfortunately, it’s also typically a significant expense!

Types of Water Heaters: Explained

Let’s say your current water heater has broken down, and you’re in the market for a new one. If you’re a smart homeowner, you’ll look into all the standard options available today rather than just buying a replica of what you already had.

Conventional

Almost every homeowner will be familiar with a conventional or tank-style water heater when it comes to homeownership. If you didn’t have one in the house you bought, you almost certainly grew up with one in the house.

This water heater has a tank that fills with water. The tank has two valves:

  • A temperature control valve, which releases at 120 F
  • A pressure control valve, which releases at 150 PSI

The water in the tank is constantly re-heated to stay at the desired temperature. Then, the hot water is piped all over the house as needed.

Tank water heaters come in various capacities depending on your budget, how it’s powered, and the size of your home (namely, how many places in your house need hot water).

Tankless

Some homes (especially new homes) have a tankless water heater installed.

As soon as you turn on the hot tap, the coils in the water heater are filled with water. Next, an element heats the coils, which heats the water. It’s the instantaneous result that people love about these water heaters.

In most cases, this type of heater is powered by gas. If they’re run on electricity, they might not be as efficient and may raise your utility bills more than you’d like.

Tankless water heaters are great for homes using a small amount of hot water, like condos or apartments. However, larger homes requiring larger volumes of water might get tepid rather than hot water coming out of the tap.

They also require a certain level of water pressure to function effectively.

Hybrid or Heat Pump

If you’re looking for ways to lower your utility bills (and who isn’t these days), consider a hybrid water heater.

This type of heater uses the heat from the ground and the air to heat water. It only uses electricity to transfer the heat to the water, rather than using it to heat the water itself, saving energy.

This type of water heater is typically quite significant because it features a pump on the top of the appliance. This means you need a decent amount of ceiling clearance to install it in your home.

And while it’s relatively inexpensive to run and easy to maintain, it has a higher upfront cost than most other types of water heaters.

Solar

A water heater option to emerge in the past decade or so is the solar-power water heater. This option is excellent for those considering adding solar panels to their home and perfect for anyone who already has them!

You need to connect your water tank to solar panels installed on your roof to get hot water. The energy from the sun is transferred to the tank via a closed-loop system made of heat-conductive material. It’s this that heats the water in the tank.

Just remember that while solar is beneficial (and cost-saving) in most parts of America, areas with low sunlight hours might not get the return on investment they were expecting.

Whether you’re happy to stay on the grid or excited to embrace the eco-friendly age, there are types of water heaters to suit.

Environmentalists can choose between solar-powered water heaters and heat-pump or hybrid options. Traditionalists or those in areas with low sunlight hours can stick with a conventional water heater or go for a tankless model. What’s essential is that you do your research on how each option meets your needs and shop around for the best prices.
