8 Services Provided by Our Engineer Consultants

Any structures that operate in a marine environment, including offshore drilling rigs, risers, mooring systems, marine vessels, wave power systems, and offshore wind generator facilities, provide unique design and operational challenges that often require significant resources and ingenuity to overcome. Many companies rely on the extensive knowledge and experience of engineer consultants to help provide critical analysis of these problems and devise piratical, cost-efficient solutions.

8 Services Provided by Our Engineer Consultants image

Specializing in marine and offshore structures, fluid dynamics and related disciplines, here are just a few of the services that our engineer consultants at Stewart Technology Associates can provide:

1) Hydrodynamic Analysis

Hydrodynamic analysis is used to accurately simulate the forces at work on a structure in a marine environment. This includes the movement of the waves, the action of the tides, the effects of undersea pressures, turbulence from structures or seafloor features, and the effect of high winds and inclement weather. By learning how these forces affect a structure, its design can be improved to eliminate possible failure points and to reduce costs and maintenance requirements. Hydrodynamic analysis can be used to examine both new and existing designs, and it can also be used after a maritime accident to help determine the cause of the problem.

2) Finite Element Analysis

Finite element analysis can be used to model how real-world conditions will affect the operation of a product or of a component of a larger system when subjected to forces such as vibration, heat, high pressures, fluid flow or other physical challenges. The results of the modeling can be used to improve the product’s design, reducing component failures and wear that can shorten its lifespan or lead to increased maintenance costs. Finite element analysis can also make a product safer, and help to determine the cause of failure in an existing design.

3) Structural Design and Analysis

Engineer consultants can help design and analyze marine structures, such as drilling rigs, jack-ups and liftboats, to make sure that they will perform efficiently and safely in a specified environment. They can work directly with a client to create a structure that will withstand the forces in a particular marine or sub-sea environment safely, while increasing productivity and reducing long-term costs. They can also analyze existing designs to improve their structural performance, productivity and safety.

4) Riser Design and Analysis

Risers are one of the most critical components in an offshore oil drilling or production platform. They carry mud and drilling fluids to the well during drilling operations and carry oil and gas to the surface during production operations. To operate safely while maximizing production, they must be able to withstand the movement and pressure below the surface, while moving fluids efficiently. Engineer consultants can be used to design an efficient riser system for production or drilling operations, determining what type of riser will be needed, rigid, flexible or hybrid, effective mooring solutions, what equipment will be required and other factors. They can also improve the efficiency of fluid moment withing the riser, increasing production, and analyze existing designs to suggest structural, efficiency and safety improvements.

5) Anchor Performance Analysis

Anchors are critical to securing marine vessels and other structures in place temporarily, permanently or semi-permanently, and if they fail to perform adequately, they can allow vessels to drift off course or to collide with other structures, leading to injuries, property damage, productivity losses or environmental concerns. To perform effectively, the design of an anchor must take into account the weight and movement of the vessel, the surface conditions and the composition of the sea floor. With an anchor analysis, engineer consultants can model the forces at work on the anchor and suggest improvements that will make it stronger, safer and more effective.

6) Mooring Design and Analysis

Mooring systems in the offshore oil industry are critical to keep the platform in place during operation, to secure tankers while transferring oil and gas and to secure other vessels as needed. They must be able to withstand the weight of the vessel or platform, while compensating for motion at the surface of the sea and keeping transfer pipes and equipment safe. Engineering consultants can analyze the design of a mooring system, including the anchors, mooring lines and surface structure, ensuring that it can perform both safely and effectively. They can also create new designs for specific applications and analyze the performance of transfer systems.

7) Oil Spill Clean-Up and Containment

Oil spills can have far-reaching consequences, from polluting the water supply and harming animal and plant life, to making beaches less inviting and hurting economies that depend on fishing or tourism. When the worst does happen, the key to minimizing the damage is to contain the oil as close as possible to the source and to clean it up as quickly as possible. Engineering consultants can help to design effective measures for both containing the oil and cleaning it up, including effective boom systems to contain the oil and techniques that can adequately model the currents and conditions at the site to make clean-up more successful and efficient.

8) Forensic Analysis

After a maritime accident or an oil spill, the original cause of the accident can be difficult to determine and, often, there are many contributing factors that make the origin even less clear. Engineer consultants can use hydrodynamic analysis, finite element analysis and other techniques, along with advanced software and extensive knowledge of marine systems, to analyze the events leading up to the accident, as well as the accident itself and its effects, to help determine the original cause. This information can be used to determine liabilities in the aftermath of the accident, to improve designs to prevent future accidents and to establish new safety protocols and programs that can help avoid or mitigate such incidents in the future.

Things to Look for When Hiring Engineer Consultants

There may come a time when your firm needs outside help from a consultant. More than likely this is good news in that you have landed an account or a project that is sizable in scope and is more than your team can handle efficiently. When that day comes, you need to be aware of what to look for in a consultant or an engineering consulting firm. At STA, we want to help you in your search, so we have put together some tips and advice to help you make an informed selection. Here are our thoughts on the matter:

It Starts With Research

There are many ways to find a suitable consultant. Usually, it is a combination of a few things. You can speak to your colleagues in the industry, you can search the internet, and you can advertise in the online trades and journals. Once you settle on some names, there are some things that you should find out that should facilitate a choice:

• How long have they been in business?

• What services do they offer?

• What are their credentials?

• Are they licensed?

• How large is their firm?

• Review client testimonials.

• Check their references.

• See where they stand with the Better Business Bureau.

These are by no means the only questions to ask or items to look for on their resume, but they provide an excellent starting point.

The Fee Should Not Be the Main Issue

You want to hire the best engineer that you can find. Trying to shop for the least expensive may be asking for trouble in the long run. Whatever you save initially, could end up costing more in time and effort. You are in the market for a professional engineer to assist your project and help deliver it on time and budget. You likely have a lot riding on the job, including your reputation. You take your car to the best mechanic. You want your kids to go to the best schools. You may be under the gun financially, and budgeting concerns could drive the hiring process, but if you can, don’t let the final decision be about the fee.

Uses the Latest Technologies and Software

The firm or individual consultant that you are considering should be well-versed in the latest technology and software that relates to your project. He or she should be able to train your staff in any new software that will be used, and get them up to speed in an efficient manner. They should be aware of the latest trends and the best way to implement the tools required for the job.
Knowledge in a Specific Discipline

Clearly, the consultant must have a background in the area of engineering that is needed for the project for which you hire them. They should be an expert with plenty of experience working within the confines of the particular discipline. They should be able to show a demonstrable knowledge of their field as well as ongoing education. You wouldn’t hire a Marine Engineer to consult on a onshore structural job. However, as we show in the next section, they should have a broad knowledge of other disciplines.

General Knowledge of Other Disciplines

A good consultant will know their field in and out. A superb consultant will be able to talk intelligently about a broad spectrum of issues. This is essential to thoroughly understanding the client’s needs. To better serve the potential client a consultant should be able to guide them towards completing the project, even if it means recommending that the client goes in another direction.  Typically a mid-sized to a large firm is better equipped for multi-discipline abilities and can offer more than a sole proprietor.

Confidence in Their Abilities

When you have narrowed your list to a few firms and are in the interview process, look for confidence in their abilities. If they are confident in their work, it will show through when you talk to them. You are looking for poise and a level of self-assurance that is obvious. You may be asking yourself ”what does this have to do with their abilities?”. The answer to that question is that pragmatic and cool-headed individuals can think on their feet during crisis situations. They will not be afraid to tell you what they think instead of what they think you want to hear. These are the type of consultants that you want on your team if you run into trouble, and every job has its share of problems.

A Problem Solver

A consultant should be positioned to make critical decisions and be able to provide you with multiple problem-solving options. They should also be willing and able to go above and beyond the scope of the job they were hired for and make recommendations for solutions beyond what you ask them to do. They should be capable of “seeing the big picture.”

The Right Consultant for the Right Job

If you have a particularly large project, you may need to engage the services of a sizable firm. If, on the other hand, you are adequately keeping up with the job but could use the additional expertise, then a single consultant might be appropriate for your needs. A mid-size company is often the best overall option for your requirements. They typically cover a broad range of engineering disciplines and are staffed well enough to respond to your needs promptly. The point is that most consultants and consulting firms don’t provide a “one size fits all” solution so keep that in mind as you search.

It will take time to find the right engineer or firm. As we mentioned above, it starts with research. As long as you do your homework and implement the suggestions as we have outlined them above, you should find a more than satisfactory consultant. Once you do, you will have a relationship that you can turn to whenever you need extra help.
