Investigating accidents that happen at sea is a top priority for maritime investigators as they use all types of resources, including hydrodynamic analysis, to determine the cause. Yet it is paramount to your company to obtain this analysis as soon as possible. Accident scenes can change quickly, especially when the accident is in maritime waters. Get the answers you need to prevent the accident from happening again and to hold the right people responsible. Here are 4 reasons to get this analysis quickly for maritime accidents.

1: Evidence Can Be Negatively Impacted

Investigating an accident at sea becomes twice as hard than evaluating one on land because the evidence can move along with the tides. The waves can change the location of the accident, making the investigation take longer because the investigators have to take into account the original scene of where the accident took place. The ocean water can also affect the integrity of the evidence the longer the evidence is in the water. Investigators can gather up what they need for their report quickly.

2: People Can Try To Cover Up Their Mistakes

While many people may feel bad about admitting that the accident was their fault, they will not be quick to admit to their wrongdoing if they can help it. They will try to blame everything, even the behavior of the water, for the mistake so they are not held liable. The hydrodynamic analysis can be performed to determine if the ocean water was really at fault, if workers made bad judgments, or if there was some type of equipment failure such as a line from single point moorings breaking away. If the accident was caused by human error, then the investigation can turn toward finding who to hold accountable so that the appropriate steps can be taken to remedy the situation.

3: Witness Accounts Can Change Quickly

With the ever changing ocean waters, witnesses can see things that may change very quickly. Also, witnesses will begin to talk to one another, as their testimony can change until everyone agrees to seeing the accident in the same way although it may not be an accurate depiction of events. Getting the right analysis in a timely manner can ensure that everything is investigated, even smallest issues that could be the actual cause and  can change the direction of the maritime accident investigation.

4: Allows Time To Gather Experts

When you get timely hydrodynamic analysis, you can get the determination for the cause of the accident before seeking out expert witnesses if the accident leads to litigation proceedings. You will have all the information you need in a timely fashion, as the experts can give their knowledge to further define the accident details in a manner that can be beneficial to your case.

5 Things To Know About Single Point Moorings

Single point moorings can be an effective means of dealing with liquid cargo. The floating buoy can be an alternative to an anchor or used in conjunction with one. Depending upon the facility, it is capable of handling even the largest of vessels – though there are things to know about the moorings before you arrive on the spot.

Type of Anchor Point

There may be sub-oil and sub-sea pipelines that are connected to the single point moorings and if you are going to anchor near the moorings, you need to be aware of the situation ahead of time. Having the necessary anchor capacities will be a must when you approach and once you are out on the water, changing out an anchor is impossible. This means that it can work to your advantage to have anchor analysis done prior to leaving the shore.

Load Capacity

Single point moorings, often abbreviated as a SPM, are used most often when there is no dedicated facility for loading and unloading cargo. If you are in the gas and oil industry, you already know what kind of capacity you have and are in need of – and if you don’t, analysis can be done to find out. This will ensure the mooring is capable of meeting your needs. If it is not, then you would have to continue on where a dedicated facility is located to help you with the loading and unloading of petroleum or any other liquid cargo.

Dominant Environment

What kind of environment are you going into? A significant amount of analysis needs to be done to determine what your rig can handle based upon the waves, the general offshore operations, and everything else. Some environments will call for more than just the SPM based upon your own rig.

Fluid Transfer Paths

There are going to be fluid transfer paths to consider with a mooring. Understanding the diagram of the mooring prior to arrival is critical. This will help you to understand placement of the buoy, the pipeline manifold, as well as the underbuoy hoses. Once the fluid transfer path is clear, you can decide if it is enough for you. Smaller vessels may be able to choose between an anchor or mooring, but with larger rigs, such as a tanker vessel, it is likely that you will need both.

Full Capabilities

Ultimately, you need to know about the full capabilities of the mooring prior to arrival. Ideally, one has been custom built for you, but this is not always the case. As a result, it is imperative that you talk to someone who is knowledgeable about the SPM. Any analysis that can be done on the mooring in conjunction with your rig prior to going offshore is going to make great improvements and allow you to prepare your staff for what they will be up against.

5 Reasons To Spend The Money On Anchor Analysis

Whether you’re in the gas and oil industry or any other industry that requires you to go out on the water, it’s critical to spend the money on anchor analysis. Even if you have engineers on staff that know how to perform the analysis, it can be advantageous to have a third party take a look and ensure that you have thought of everything.

Understand Water Patterns

There are going to be different water patterns based upon location as well as how far out from shore you go. The ocean waves need to be fully understood to prepare your rig and ensure that you have anchors heavy and long enough to handle all that you may encounter while out on the water. Insufficient anchors when it comes to big waves could result in drifting, and that can damage equipment amongst other things.

Explore Depth Issues

The depth is going to be another issue to be concerned with. An anchor is only effective if it reaches the bottom of the ocean, otherwise you can find yourself floating at sea, at the mercy of the waves. There has been a lot of deep sea exploration and using this information in conjunction with computerized analysis can tell you about depth issues in certain areas of the world.

Identify Risks

The risks of being on the water need to be fully dealt with. Stewart Technology Associates uses advanced programming with Orcaflex software. This technology can provide a “worst case scenario” for you to use to help you better identify the risks so you know what could potentially occur. Your engineers on staff may not have access to such advanced software, which means they cannot provide the same level of analysis.

Obtain the Necessary Equipment

Before you can go out on the water, you need to know what’s needed on your rig. This is not the easiest thing to do because once out on the water, getting additional equipment may prove to be difficult if not completely impossible. With anchor analysis, you can learn more about the water and what’s needed of your rig to make the necessary acquisitions prior to going offshore.

Train the Staff

All sorts of analysis, including that of seakeeping analysis, can provide details as to what the water is going to do while offshore. This information can be used to prepare the staff and train them adequately. There may be situations that occur while on the water, lowering an anchor or something else that could prove catastrophic if the employees don’t know what to do. A few pages of analysis can be just what’s needed to keep everyone in the know and provide sufficient levels of training to anyone who will be out on the water so they are capable of expecting the unexpected – and will know what to do when the unexpected actually occurs.
