A mooring analysis is common throughout marine and offshore industries. It’s not always easy to create a floating dock or keep a vessel from moving and it’s important to have as much information as you can about the subject. This is one of the most popular and most necessary forms of analysis as it applies to so many different projects.

By understanding a mooring, you understand the need for it to be able to withstand the water pressure that it is in and be strong enough for whatever is being tied to it. Some moorings are able to support one thing while others don’t. Different types that exist include:

–           CALMs

–           SALMs

–           Turrets

–           Towers

–           Submerged buoys

–           Harbor moorings

What’s used for a Jet Ski is going to be very different from what’s used for a dolphin encounter or a cruise ship. A significant amount of mooring analysis is required in order to look at the details. The depth of the water, the waves, the salinity, and various other factors are taken into consideration.

Stewart Technology Associates uses state-of-the-art marine software in the form of OrcaFlex. It allows for a comprehensive solution when organizing data and being able to establish worst-case scenarios. Once the numbers come out of the software, it is then analyzed even further and recommendations can be made in terms of providing input on what a mooring needs to consist of.

It’s important to realize that anchor analysis is very different as a mooring is a permanent or semi-permanent structure that is in place whereas the anchor is on the vessel and then thrown down as a way of providing a temporary pause to movement.

Understanding waves and other details become critical. A passing ship can have an effect on the mooring because of the waves that are generated. All of these become factors that must be considered to avoid accidents.

When you are going out on the water, your goal is to minimize risk. You don’t want to encounter any fatalities or lose any business as a result of an accident. With mooring analysis, you are able to determine what kind of spread or single point mooring is needed based upon your individual project. You cannot rely on analysis done for anyone else as you have different things going on and they must be taken into consideration to yield the most positive results for you.

Analysis doesn’t have to be done by you. In fact, it should not be done by you as it’s critical to have a third party that will be impartial to the outcome of the analysis. A third party will not hold anything back and provide you with the details that you need to understand the type of mooring you need to locate, use, and/or build. When these details are at your fingertips, it promises better results when you are on the water.

What A Marine Accident Investigation Can Tell You

Accidents can happen out on the open waters and that’s when a marine accident investigation is needed. It can tell you what happened as a way of learning from your mistake and avoiding something of a similar nature in the future. There is the need to find out the legal, environmental, and logistical effects of an accident.

While mooring analysis and other types of analyses can be done to help you determine what the water and other conditions are going to be like, accidents still happen. Despite how much you prepare, something eventually goes wrong and it may not be obvious who or what is responsible.

Some of the reasons for accidents can include:

–           Human error

–           Natural disasters

–           Faulty equipment

When there is an expert witness, it’s possible to get evidence examined and that can help to work through an accident. A marine accident investigation can help to identify the responsible party or parties, solve legalities as to who needs to be called out on the accident, and more. There are various technical issues that can occur and if there have been mooring problems or something else, you need to know about it as a way of preventing such in the future.

Sometimes, the unexpected happens. There are large ocean waves that are unpredictable and particularly in the Pacific and Arctic Oceans, they have been so large that there is no sea vessel that could be safe from them. Nature can be unpredictable and it requires a marine expert to determine if that might have been the cause of an accident.

Stewart Technology Associates offers marine accident investigation services and they become an impartial help in determining what happened. They may be hired by one party of the accident, though it is their responsibility to weigh all of the evidence fairly. Everything will be examined and after they have gone through all of the details, a determination will be made as to why the accident occurred and what can be done in the future to prevent such a thing.

Ultimately, the investigation is going to tell you what you need to know in order to move past the accident and learn from it. If legal action is required or has been taken against you, the details will be provided so you know what you need to defend or who you need to go after. Some accidents are more severe than others and can lead to fatalities and cost thousands or even millions of dollars. These are the accidents where a thorough investigation is a must to ensure that such a thing never happens again.

Your company’s name is on the line every time there is an accident. When you can give workers, investors, and the media peace of mind as to what happened and take actions to prevent it in the future, it will allow you to get the spotlight off of you.

Three Reasons For Hydrodynamic Analysis

There are many reasons for hydrodynamic analysis. Generally speaking, it helps to provide details about how the water is going to react. Whether you’re boating or going out with an offshore oil rig, you need to understand the behavior of the water as a way of preparing for everything that you could potentially encounter.


Once you are on the water, you cannot simply obtain more supplies. What is on the boat or the rig is what you will have to use. This includes anchors, drop lines, and anything else. If you don’t know what the water is going to do in terms of temperature, salinity, depth, waves, and more, it could result in potentially disastrous accidents.

You may need chains of various lengths, risers that are capable of going into deeper waters, and more. It’s best to have these on the rig so you don’t have to cut a project short because of not having the right supplies.


Many common accidents aboard a ship could have been avoided through hydrodynamic analysis. Everything from anchoring problems to men overboard accidents have occurred and that’s because everyone who was out on the ship were making assumptions about the behavior of the water instead of going with actual numbers.

Stewart Technology Associates can provide the analysis and even conduct a marine accident investigation. They have up-to-date technology that allows for numbers to be crunched and assumptions to be made. It also helps to establish worst-case scenarios in order to be prepared.


It’s important to be able to prep your team that’s going to be on the water. They need to know that swells could reach a certain height and that there may be instances where they need to use a different type of anchor or other piece of equipment as a result of the water that they are in. By having more information at your fingertips, you can go through various training modules and help your team to expect the unexpected.

When you know more about how waves work and everyone around you does, too, it works to your advantage. You cannot trust that everything will work itself out. There have been significant waves reported throughout the Pacific and Arctic Oceans. When your projects take you into unchartered waters, you cannot rely on what others have reported – the research has to be done on an as-needed basis.

The hydrodynamic analysis does not take long, so there’s no excuse for skipping it. You don’t even have to rely on your own team to do the analysis because a third party can do it and provide you with more advanced technology to ensure the numbers are accurate. Recommendations can come from the analysis as well, allowing you to get a second opinion on the supplies needed, the best way to avoid marine accidents, and more.

Why Anchor Analysis Is Critical

Any time that you are dealing with the water, you need to make sure you have the analysis to avoid disaster. Anchor analysis is critical so you know how you will be able to anchor while at sea without causing damage to the vessel and without drifting away. There are variables that need to be considered and failure to consider them all can lead to disaster.

It’s always a good idea to practice boat safety and that includes knowing the supplies that need to be kept on board. Having an anchor is only effective if it is capable of doing its job.

When you are anchoring, it’s important for anchor analysis to take place. With the right data, you can shop for the best anchor for your time at sea. It will also help you answer such questions as:

–           Weight of anchor

–           Length of chain

–           Material of anchor

–           Area of boat it should be cast from

There are variables that have to be taken into consideration. Knowing your course will help you to be more specific within the analysis. The depth of the water, the amount of waves that you will experience, and even the level of salinity are all things that should be known. While analysis will plan for the worst case scenario, you want to give the system an idea of what you are going to face while on a boat or other sea vessel.

Stewart Technology Associates uses advanced technology to provide analysis. This includes Orcaflex software that can do a significant amount of mapping and data analysis on your behalf. By automating a lot of the process, it’s possible to eliminate human error. After the initial analysis is made, the human analysts will be able to provide recommendations to help you obtain the necessary supplies and take the necessary precautions.

Various types of analysis can be obtained so you have all of the numbers and scenarios in front of you. This includes hydrodynamic analysis to help you understand the behavior of the water and how it can impact your project that is taking place on the water.

Your ultimate goal should always be to avoid accidents and this can be done by ensuring you know what’s going to happen when you go out on the water. Anchor analysis will ensure you have the needed equipment to anchor all the way down to the bottom of the ocean and remain there without drifting or experiencing any other complications.

The more numbers you crunch and the more data you input to the system, the easier it will be to find out what’s going on and prepare your vessel and your crew for their time at sea. Without it, you could end up with all sorts of problems – and these can be avoided.
