The EU aims to reduce dependency on imports of raw materials. ROVs and ROV Cables play an important role in harvesting such materials in European waters.
For a cutting-edge EU Research Project, DeRegt was asked to join an EU-funded consortium of 14 companies. Industry, research institutes and service companies across seven different countries joined forces.
Subsea cables are stored on land and (mainly) used in water. That means the temperature difference between deploying and retrieving can be high. Therefore, controlling the cable's temperature in-field is often a challenge.
Verifying the required specifications is perhaps the most crucial part of designing a naval subsea cable. After all, as an engineer, you must be able to prove that the cable works as it is supposed to. There are five different ways of verification, one of which is subsea cable testing.
At DeRegt, we use a Design Compliance Matrix (DCM) as the foundation for the verification process. This way, you know that all of your specifications are thoroughly verified. This blog explains how a DCM works and what verification methods there are, including examples.
In a previous blog, we listed all types of sonar system requirements. A couple of verification methods can be used to verify your cable specifications. Extensive testing can’t always be avoided, but luckily, some offshore cable specifications can also be verified by analysis. After all, a lot of data is available on materials and surroundings.
Environmental sonar system requirements are essential requirements in the naval world. Fortunately, these requirements are examples of analyzable specifications. They usually do not require expensive testing, since materials and the environmental conditions they can handle are documented. In this blog, we will list the most common environmental requirements and how we make sure they are verified by analysis. There’s also one exception to this rule.
As a defense engineer, you can’t know everything about every aspect of your sonar system or other underwater defense systems. However, the client probably holds you responsible for the final result, and thus for every component. Therefore, it is crucial that you have knowledgeable partners about specific components within your subsea project.
Early Supplier Involvement is key as it allows your suppliers to become partners. For example, if your subsea cable manufacturer is known in an early stage of the project, the cable experts can adjust the cable perfectly to the rest of the system. Early Supplier Involvement has more advantages, as stated in this blog.
Every underwater defense cable has its own requirements that are absolutely crucial. As an engineer, you want to aim for the most effective and efficient way of verifying these to your client. You want to be sure everything is thoroughly verified, without paying too much for extensive subsea cable testing.
In this blog, we explain how we determine which requirements have to be tested and how some factors can be analyzed with data. We then explain some important qualification tests for underwater defense cables, that are crucial for a successful underwater defense project.
In creating a Subsea Cable Design, there are a lot of aspects to consider. It is important that the final design properly fits into your sonar system (or the subsea system you’re creating). As an engineer, you want to have a firm grip on the project. The decisive ingredient in doing that is a clear design process.
In this blog, we discuss the advantages of having such a design process in place, the design process of our cable experts and how this subsea cable design process will eventually help you in properly validating your specifications.
The design of a sonar cable is always unique. After all, each sonar system benefits from a fit-for-purpose sonar cable, of which the most crucial requirements differ. That’s why it is important to know early on what the main requirements are for your subsea project. They form the basis of every sonar cable design.
In one of our previous blogs, we mentioned that Survival Load is an important Operational Requirement for naval defense systems. Now it’s time to dive deeper into these requirements. What is Survival Load, why is it so important for naval defense systems and how are elongation and stretching connected to it?
By understanding more about these concepts, you’ll have more grip on your sonar cable design as an engineer. An important asset if you have to validate your naval defense system to the customer.
One of the components that always recurs in the design of a naval sonar cable is the strength member. There are several options in the design, depending on what the application of the cable is.
In this blog, we will discuss how the strength member is determined. First, the important functions of the strength member are listed, after which we will explain what types there are and how our experts determine which strength member is used.
