Anchor analysis is important in marine drilling operations, and Orcaflex software is some of the best for the job. The industry-leading software is used by many of the top companies that work in marine drilling and building. Steward Technology Associates offers technology consultancy that includes anchor analysis with this programming technology, with full price ranges available on the site and upon request.

The company has been in business since the 1980s and has worked with drillers from all around the world. The company works with the drillers to collect data and to analyze it, so they can get their work done more efficiently and create an atmosphere that is safe for workers and the environment that surrounds them. The data also helps drillers make improvements to the performance of marine and offshore structures, so they can be safer and adjusted for better performance over time.

STA’s anchor analysis looks at an operation on the whole, so this can show the drillers how to increase safety levels at the site of a project as well as how they can improve their productivity levels. There are often reports that show how to yield value right away, but the analysis also looks at how to increase value over the course of time and into the future.  The company has programming with OrcaFlex and other software that will help the analysis be completed fully.

There are different versions of the software that a company can choose to use for analysis, including Orcina, a well-known platform that can help in almost every aspect of marine building, drilling, and exploration. The Orcina line includes OrcaFlex 3-D, Orcalay, and Orcabend. The 3-D program offers tome-domain anchor analysis of marine systems that are flexible and in areas with irregular waves, like near-shore operations and those in rough waters. The Orcalay program offers static pipe-lay analysis, so hardware can be laid appropriately over a distance and made to work correctly without major faults or losses in productivity. This type of software can be used to determine lay patterns over land and sea when necessary, helping avoid costly misalignments.

Orcabend is a bend design program that is available upon request. The program is one of the leading software packages in the industry and can help with installation planning, towed systems, marine renewables, seabed stability, and other important factors that drillers have to consider on a daily basis. With the ability to check the seabed, for instance, companies will be able to be sure that their installation won’t shift over time, leading to fewer problems like damage from seabed settlement or cracking from uneven angles or water levels over time. Without checking these vital aspects of drilling, the installation could be damaged over time and lead to dangerous problems with the area.

When an accident takes place, OrcaFlex may be able to help a company or investigators understand the underlying faults that led to an issue. This special software is produced by Orcina, the leader in offshore dynamics, and it can help with marine accident investigation.

Accidents are always something you’ll want to avoid as a business owner, and with this program you can save yourself a lot of trouble. Analyzing potential issues and trouble areas can reveal a lot of problems ahead of time, so you can be sure to address them before they become an issue that will cause a serious problem in the future.

However, if a marine accident investigation occurs, you’ll want to make sure you’re analyzing your failure through and through. It’s important to make sure your platform and mooring is in good shape so you can prevent future incidents and be sure that your workers and investments are safe and sound on the water. On top of this, with the right analysis, you’ll be able to be 100-percent certain that you’re doing everything you can to help the environment, even when drilling to remove oil and other minerals within the surrounding environment.

There are many reasons to use the software. You can use it for riser analysis, mooring analysis, towed systems, installation analysis, cable dynamics, and other purposes. Depending on the layout of your systems and company, you can even have customization put into place by STA.

Riser analysis includes ways to review your risers, including those with unbonded and bonded constructions. The analysis includes hybrid risers, umbilicals, and risers for CALM. Mooring analysis includes spread moored systems, single-point moored systems, jetty mooring, and harbor moorings for dolphin interactions and passing ships.

For towed systems, OrcaFlex includes the ability to work with seismic arrays, towed fish, towed bundles, and multiple surface vessel analysis. For cable dynamics and pipe lay analysis, drillers may use OrcaFlex to help determine pull-ins and hook ups, fiber-optic communication information, reel-lay, S-lay, and J-lay.

You can even use OrcaFlex for special buoy systems, including Oceanographic buoys, defense system buoys, air deployed systems, and others. For mudslide analysis, wave power systems, and forensics, the software provided can help you get everything worked out from A to Z.

If you run into problems with your mooring, for instance, this program can help you determine what caused the issue. Mooring failures can be analyzed by STA, and the analysis includes pipe laying analysis, wave power systems, expert witness marine, and other vital investigational techniques. The analysis will help drillers understand the failures, why they occurred, and what to do to help prevent them in the future.

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.
