Issues happen on the water all the time and Orcaflex works to prevent these. Analysis of moorings, tie-downs, buoys, rope materials and potential marine conditions can help you to make better decisions for your business. You don’t want to run into problems and when you have analysis you can count on, you avoid problems more often.

The last thing you need is a marine accident investigation to take place because you failed to use Orcaflex to learn about the water conditions. All it takes is a little extra wind or waves to throw a major wrench in your offshore setup. Regardless of whether you’re drilling or you’re setting up a fishing expedition, you need to plan for everything.

When you have the right analysis software, you don’t need to worry about whether you are making the best decisions because the reports will give you confirmation one way or another. You simply need to work on training employees so they understand how to use the software to pull the necessary reports.

Orcaflex is only going to be as good as the person working the program. This means that employees need to be trained on it. You should then ensure that employees are training new employees so everyone is capable of using the software. When more people are capable of analyzing the data, you can avoid mistakes on the water.

If a buoy isn’t capable of dealing with strong winds, you need to get a stronger buoy. If a mooring is loose, it may involve vessels being pulled up from the water. You don’t need an accident to take place on your watch. Not only is it going to cost you money, it could cost you lives as well. Additionally, you may face a significant amount of bad press due to an accident that could have been avoided.

The water is not as friendly as many people believe it to be. If you’ve ever been out on a boat during a tropical storm, you know the wind and waves can be very violent. They can cause a significant amount of damage and put a lot of people and equipment at risk. All it takes is one situation where the analysis isn’t done to cause a devastating outcome.

You need to work with worst-case scenarios. You won’t know how to prepare your boats or your staff unless you do. This will ensure you avoid problems altogether. If you plan for a worst-case scenario with Orcaflex, you will get the reporting criteria you need to make the necessary adjustments to your ties, your buoys and everything else.

When you work on the water, you have to be prepared. The only way to be prepared is with sufficient analysis. technology software can do the analysis so you don’t have to. Orcaflex is used by top technology firms around the globe.

Marine Accident Investigation: Get The Answers You Need

[Posted on November 13th, 2013 by Bill Stewart]

A marine accident investigation should always take place following an accident. Regardless of whether it was a boating accident or an offshore drilling incident, you need to know what went wrong. Without knowing, you are likely going to make the same mistakes again – and this can cost you a significant amount of money.

The worst boating accidents have been due to someone not paying attention. It may have to do with not paying attention while driving a boat or not paying attention to the overall conditions. With a little analysis on the front-end, many accidents could have been avoided.

You may find out from the marine accident investigation that mooring analysis could have prevented an accident. The moorings are used to keep boats and other vessels tied down. They are permanent structures that go into the water. Depending on height, width and material, they can only handle so much weight. The waves and the wind can play a dramatic role in whether the moorings hold up.

Even offshore drilling has been exposed to a variety of problems. A marine accident investigation can be ordered for these incidents as well. By carrying out a full investigation, you can learn what went wrong. Sometimes what caused the accident couldn’t have been foreseen. In most cases, however, they are entirely preventable.

With a marine accident investigation, you can learn what went wrong. The next time you go out into a boat or set up an offshore drilling project, you will know what to do differently. You may have to order more analysis of the environment or you may need to focus on other things. You may even need to concentrate on training your employees on different scenarios that can occur on the water.

Not knowing is what will get you into trouble every time. You want to know about your employees and about the weather. So why wouldn’t you want to know about what caused the marine accident? Investigations can take place by companies that know how to dig deep into the problem, review damage, and run analysis based upon the conditions that were encountered when the accident took place.

The more answers you have about why the accident took place, the more precautions you can take in the future. Marine accidents can cost money and cost lives. You don’t want to be associated with these and this is why a marine accident investigation needs to be ordered before you proceed.

Once you get the answers you need, you can make the necessary judgment calls to change the training protocol, order better materials, and change some of the ways materials are engineered. You may even decide to invest in some technology software that can provide you with better analysis. This will help you prepare for more scenarios when you’re in the water.

3 Reasons For Mooring Analysis

No one wants to deal with marine accidents and mooring analysis can prevent this. A boat or other vessel needs to be tied down when it’s at port and this means that the mooring needs to be adequately grounded. Through the use of advanced software, analysis can ensure that all aspects have been considered.

When you schedule mooring analysis, there are several things that should be included in the report:

  • Wind and wave capability
  • Shielding of pier
  • Options to lock vessel
  • Pre-tension for mooring setup
  • Rope properties

No one wants to see their boat drift away and this is one aspect that the mooring analysis can help with. If the mooring is not stable enough, the boat is going to be tied to it. As the wind and waves rock the boat, it may cause enough pressure that the mooring breaks away, causing both the mooring and the boat to drift away.

Another reason for the analysis is to help with a marine accident investigation. If there was any kind of accident involving a boat or other vessel that was tied up at the pier, investigators are going to look at the mooring. If the mooring wasn’t placed properly to begin with, it could be what caused the accident.

A lot of damage avoidance can be put into place with mooring analysis and this is the third reason to get the analysis when putting a mooring in place. Hurricanes can wreak havoc on the land and the sea. If a mooring is only capable of handling a certain amount of wind and wave action, then you need to know this. Some docks or piers will have warnings of when you shouldn’t tie your boat up.

There may be instances where you want to bring your boat onto land. If the mooring has not been analyzed or it is not stable under the current conditions, you have to do what’s right for your boat. You don’t want to lose it to the sea, so you have to secure it in one way or another. If you cannot rely on tying it up in the water, you may have to bring it out of the water entirely. This way you won’t have to worry about problems where it could be washed away.

If you’re dealing with severe weather, you want to make sure you drag the boat or other vessel up the shore enough that waves cannot wash it back down. This will keep your boat safe no matter what kind of weather you are dealing with.

There are all sorts of reasons for scheduling a mooring analysis. Once you have the analysis in hand, you can provide the necessary notifications to boaters. You can also train your employees that work on the dock or pier to help with securing vessels to the mooring.

Riser Analysis and Off-Shore Drilling

Riser analysis is vital to your offshore-drilling company. It offers you information about the type of riser you need, the quality of your riser, and any problems you might have or be having. There are a number of different types of flexible risers, and with riser analysis, you can determine which riser will work best for you.

Stewart Technology Associates has used OrcaFlex technology to analyze risers. The software allows the company to look for critical issues and to determine solutions with all the information needed. This software is one of the most effective products in the marine technology world, and it’s used with over 170 organizations all around the world because of its quality. Stewart Technology Associates offers this technology and the ability to perform services like riser analysis, CE marking, jack up analysis, and others.

Your riser is an important part of your business. Risers are used to transport materials from the seafloor or below to your platforms at the surface, where you can then transport and use the materials. Risers often are referred to as pipelines, as they are essentially vertical pipes.

There are a number of different types of risers you can choose from including attached risers, steel catenary risers, flexible risers, and others. Attached risers, for example, are often used with fixed facilities because they won’t be moved often or at all. Steel catenary risers are often considered the best value for your money, as they are flexible and can be made hundreds of meters long. They are often attached to floating platforms that may move, and they are sometimes curved to withstand more movement than other types of risers.

Pull tube risers are threaded through the center of the facility, which means that there are actually two pipes in use. The pipe on the sea floor is essentially pulled up through the secondary riser to allow the transport of fluids and gases.

Flexible risers were made to withstand vertical and horizontal movement. This means they can easily be used with floating facilities that have to move or be moved often. This is commonly used because of the ability of the risers to stand up to the changes in the ocean’s movement, and buoyancy can be changed to suit the area and needs of the particular riser.

With riser analysis, you can be certain that your riser is working correctly, so you won’t be leaking important materials or trying to work with a pipe that doesn’t want to function in the environment where you’re completing offshore drilling. Stewart Technology Associates has worked in the industry for over 20 years and can help you determine the best riser choice for your needs or work with you to analyze the risers you already have.

Why Focus On Cable Dynamics With Offshore Drilling?

[Posted on October 9th, 2013 by Bill Stewart]

Cable dynamics is a big part of offshore drilling because you have to maintain stability at all times. Each time you add more weight, the cables have to be adjusted to ensure there are no problems with the overall stability. This means it has to be a primary focus with each and every thing that you do on the rig.

There are a lot of things that need to be considered when you set up an oil rig. You need to look at offshore living to ensure all of your workers have a place to sleep as well as to entertain themselves when they are not working. This is added weight on the rig and will affect cable dynamics.

You will need to look at steel catenary risers to accommodate all of the waves that you will encounter. Each and every area of the world has different wave patterns. As a result, you will not be able to use the same cable layout every time. It will have to be recalculated because you will have a completely different list of “what if” scenarios to worry about.

Your goal is to minimize the number of problems that can occur when you are out on the rig. Each and every time there are rig problems, it ends up in the news. Any bad press is enough for investors to pull out of your project and this needs to be avoided at all costs, literally.

With cable dynamics, you can ensure the calculations are accurate by using the right software. You can also have a professional analysis done to run the calculations for you again. This extra set of calculations can ensure that you have the weight effectively managed and balanced and that you have thought about how the water is going to play into the stability of your rig.

Depending upon where your rig will be, there are going to be all sorts of things that can happen. If there is a large storm while you are out there, the waves are going to get larger and this is going to send the rig in motion. If you focus enough on the cable dynamics, you will have enough tension in the cables but provide enough slack to avoid anything snapping. The last thing you want to do is lose equipment because you didn’t make accurate assumptions about your environment.

There is enough to worry about in the world of offshore drilling that you don’t need something else to worry about. You may not have a technolgy expert on your rig and this means that you need someone else to be able to run your numbers for you.

If you take the time to focus on cable dynamics, much of the other things that are of a concern will fall into place on their own.

The Steps to a Career in Marine Accident Investigation

[Posted on August 1st, 2013 by Bill Stewart]

Accidents happen on land and sea due to neglect, intoxication or bad timing. Investigators on land have skid marks, debris and eye witnesses to give clues as to who was at fault. Accidents on the ocean have few of the elements of an automobile accident. Each year hundreds of incidents at sea are reported to the National Transportation Safety Board (NTSB); the United States governing office responsible for  Marine accident investigation .

Training classes cover the human error factor involved before the accident occurred. Students are trained to interview witnesses and casualties in ways to gather leads as to the cause of the incident. Prospective investigators learn to gather and analyze data from technology and deck operations. They study techniques of mooring and mooring analysis.  Understanding water survival and marine specific injuries are learned, as well.

Applicants from all over the World may attend and investigators from other NTSB units. College students can join in order to conduct course research. Classes study maritime accidents and investigate real incidents to further student’s understanding of the cause and measures to take after their conclusions are drawn.

Upon completing the course, students are able to analyze all the data collected, draw to a conclusion the reason the incident happened and prepare a report for official and media sources. The report also presents steps to take for avoiding the same problems in the future.

The accidents turn tragic when lives are lost and the Marine accident investigation then becomes a cautionary tale. When children lose their lives, every aspect of the incident goes under the microscope to insure the same accident will not happen again.

Most recently, investigators found crew members on the Costa Concordia guilty of manslaughter. The ship carried 4000 passengers and crew when it was run onto a reef causing the ship to tip and sink. As a result, 32 people died before rescuers arrived. The investigator’s report gives the sequence of events that caused the ship to run aground. The ship was off course due to inattention by the captain. Once the captain realized the problem, he told the helmsman to adjust the ship’s course. The helmsman, instead, turned the ship in the wrong direction and hit the reef.

The helmsman and four other crew members received sentences of less than three years. The luxury liner’s crisis coordinator was sentenced to two years for not revealing the severity of the accident to media centers which slowed rescue operations. The captain of the ship is being tried separately and is accused of abandoning the ship and all the passengers.

The marine accident investigation into disaster’s such as this bring to light the danger passengers face when a crew becomes complacent. Finding the cause, whether it be human error or catastrophic equipment failure, helps engineers and designers build safer vessels.

Mooring analysis can help a drilling company understand the area where they’re working. For marine and offshore structures, Stewart Technology Associates has all of the vital technology needed to work correctly and to ensure safety. The company can help drillers perform structural design analysis, hydrodynamic analysis, mooring analysis, and more.

The company has extensive offshore experience and has state-of-the-art software that helps drilling companies and marine workers understand exactly what they’re doing, so it can be done right the first time. Pricing is available on the site for things like anchor analysis and mooring analysis, so there is never any question of cost.

For mooring analysis, companies can use the Ballast Control Simulator software provided by STA. Pricing starts at $8,000 and includes BMS, ballast control, and mooring simulation software.

Another product available is STA 2-Point, which offers the static analysis of two-point mooring systems in shallow water. This analysis costs $1,500. Single-point moored tanker and capacity information may be investigated with STA SPM, which costs $4,000 for analysis.

For companies looking to lay out a mooring system across the water, try STA Laymoor. This program provides all the tools needed to lay out the mooring system. It is a low-cost program at $450. For advanced management of mooring and risers, STA Rigman is available as well, and this can be used as an advisor for floating drilling rigs, like those found in deep-sea areas. The management software is available for $30,000 through the company and includes BP.

Not all programs will be perfect for every task, which is why STA offers customization at an extra cost. Some pricing is available on request, so it’s easy to determine the amount needed to better specialize software for a project.

Making sure your mooring is in place and secure is vital to making your operation safe. The mooring, which holds your entire vessel or platform in a secure location, provides the security needed to keep your workers and vessels safe during business operations.

From permanent anchor mooring to swing moorings, fore and aft moorings, or pile moorings, the analysis available through STA can help you be sure that your vessels and workers are secure. You’ll be able to determine holding power and the potential for damage to the surrounding environment (so you can prevent it). No matter which type of mooring is being used, the software from STA can determine if there are changes you can make to the platform to help prevent damage to the area around you or to your vessels and which things you can do to improve productivity and safety levels.

Ensure Structural Integrity With Riser Analysis

[Posted on July 24th, 2013 by Bill Stewart]

When it comes to offshore drilling, there are plenty of opportunities to get involved with drilling and exploration and riser analysis is a must. As your company gains contracts and you send rigs out into the deep waters, you need to look at how the risers are selected and used.

Regardless of whether you are using flexible or rigid pipelines, it’s necessary to look at the static and dynamic stress – and this is one of the things that can be done during riser analysis. This ensures you have thought of everything, including load capacities. As you do this analysis, it will allow you to choose the most effective risers for the job.

Many offshore drilling companies have begun using flexible risers as the default riser style because it can deal with horizontal and vertical forces. While this is true, it is not always going to be the best when it comes to fatigue – and this is another instance where riser analysis can show you what is truly going on so you can make an accurate assessment as to the risers you obtain as well as the design that you put into place.

Where you will be drilling matters. The water in one part of the world is going to be entirely different than the water in another part of the world. Waves, temperature, salinity and various other factors must be calculated. You will need a vortex-induced vibration assessment to ensure you have captured every possible scenario.

A sound structure is of the utmost importance. You will likely have a plan in place should you have an emergency disconnect of a riser, however you want to prevent this scenario from happening to begin with – and this is why it is of the utmost importance to spend the time ahead of time to get the riser analysis done.

There are several ways to achieve this analysis – and it shouldn’t be a choice as to which you should do – you should be doing both simply to run your numbers in multiple ways. The first is to use software to run the calculations and scenarios. OrcaFlex is a popular software program to run scenarios when you are offshore drilling. It will do a lot of assessment and analysis on your behalf. The second is to work with a consulting group that will run a variety of scenarios by you as well as look at the design of your rig with risers to ensure structural integrity is maintained throughout the scenarios.

Once you get out into the deep waters, you are a long way away from assistance of any sort. You will have communications, but it can take a while for someone to get out to you. If you lose structural integrity, you lose everything – and that’s not something you should deal with. Riser analysis can be the way to double check all of your calculations before heading out.

Flexible Risers Provide More Options In Offshore Drilling

[Posted on July 17th, 2013 by Bill Stewart]

When you create a rig offshore, you need to focus on flexible risers. These kinds of risers are able to withstand vertical as well as horizontal movements. This makes them one of the most ideal options for floating facilities. Originally used to connect production equipment aboard floating facilities, it is now being used as the primary riser solution offshore.

As you look into riser technology, it’s important to know about the different configurations available for these risers. This includes a lazy S and a steep S which will utilize various anchored buoyancy modules. As you use these different configurations, you will also want to use riser analysis to ensure you know what you are getting.

It can be of great assistance to use software in order to learn about how the different flexible risers will operate in the water once you have placed them. Without going through a variety of tests on land, you are going to run into a variety of problems off land. Software can provide you with a variety of results to ensure you have made the accurate configurations for what you will be doing and where you will be doing it.

For example, when you use flexible risers, you will want to consider stress technology and simulate the recoil that will occur if you have to make an emergency disconnect. You will need to understand the operating limits including tension, stroke, and heave as it results to riser recoil. To ensure you have thought about all of these aspects, it can also be advantageous to work with an technology firm that specializes in offshore drilling.

Various components will be used along with flexible risers. You may need telescopic joints, keel joints, suspension joints, and various other things. It all depends on where you will be doing the drilling and what kinds of conditions your materials will be exposed to.

Ultimately, while risers provide you with a significant number of options for offshore drilling, it is still important to focus on riser capability and analysis. This means looking at tube wall thickness, riser configurations, buoyancy effectiveness, and various other aspects.

Having a flexible drilling riser is going to provide you with flexibility – but this is not enough. You have to focus on all of the other areas to ensure that you have a strong rig going forward. You also have to consider emergency situations – as they are more likely to occur offshore then you may realize.

With a strong combination of analysis software and technology consulting, you will be able to use flexible risers throughout your rig and use them with confidence knowing that they are going to handle everything that your environment is going to throw at them. Additionally, you will have the know how to respond in the event of an emergency, regardless of how major that emergency may be.

Tips For Cable Dynamics With Offshore Drilling

[Posted on July 10th, 2013 by Bill Stewart]

It’s important that you focus on cable dynamics when you create an oil rig because you don’t want anything to go wrong. The productivity of your oil rig depends on all of the cables. This includes the length of the cables, how they will respond to the different environments as well as the strength that they are able to hold.

The last thing you want is to encounter oil rig accidents. Not only can it lead to fatalities but it will be all over the news. You don’t need any bad press against your business, which means that cable dynamics has to be a top priority.

You need to work with a professional company that can provide you with technology consultations. This allows someone to take a step back and look at your project with a different set of eyes. As a result, you can ensure you are getting the type of work you need done. You will be able to build everything with the knowledge that you are using the right cable setup.

You cannot rely solely on books to teach you all about cable dynamics. You need to know about all of the different supplies that are available to you – such as flexible risers to help simplify water pumping.

The cabling is of the utmost importance because it will keep you afloat when you are thousands of miles off shore. You do not have anything if you do not have a strong support system. Various things will be hanging from your boat – and if the cabling is not strong enough and not set up accurately, it’s going to cause a lot of problems for you.

Software can be used to help with various aspects of cable dynamics. This allows you to measure everything and place a variety of scenarios into the computer to ensure you have thought of everything. Remember that because of the water depth as well as the waves that are created, your cabling will need to hold up to all of it.

The idea is to measure twice and cut once. The principle that is used in building can be used in offshore drilling as well. Measuring two or three times with the help of software and with technology consultants can save you a lot of time – and a lot of money. Once you get into the water, you need to run efficiently – and you cannot afford for accidents to happen.

This is why it is imperative to work with a company that understands offshore drilling. Finding a company with years of experience in design and cable dynamics can ensure you have thought of everything before you get out onto the water. Offshore drilling can be rewarding as well as dangerous, so cabling has to be a top priority even before you venture offshore and into the unknown.
