While the ordinary individual might have a little difficulty positioning the name Jan De Nul, as in “JDN Group”, that’s not always the situation throughout components of Europe and also in maritime circles. There the Belgium- based firm is understood for its dredging capacities and also top-level tasks in Dubai and also the Suez Canal.
In enhancement to dredging, JDN is constructing a track record as an international gamer in its various other company sectors: overseas solutions, civil design, and also ecological. Today, the firm remains to spend greatly in all locations of business. And in 2015 JDN additionally reinforced its hydraulic design proficiency and also structure structure proficiency and also capacities via the procurement of structure professional Soetaert NV.
Design to implementation
One vital approach towards the success of any kind of company is to make the client’s life much easier. And JDN has actually welcomed this viewpoint. In the previous job was concentrated on complying with client specs. Today, the firm has actually embraced a consultatory strategy and also a growing number of of its clients are relying on JDN for the solutions.
The firm’s multidisciplinary groups comply with the incorporated strategy– whatever from style to implementation is being looked after in-house. A consumer constantly obtains an innovative and also ingenious service customized to their particular demands; and also some tasks also consist of upkeep and also funding. This undertaking is sustained by a huge style and also design division offering all locations of rate of interest.
New innovation financial investments
An vital part of JDN’s company approach is continual financial investment right into brand-new innovation and also tools. This is ideal highlighted by analyzing its fleet of greater than 85 ships, 47 of which were developed in between 2007 and also 2013.
While larger isn’t always much better that does not apply for large global dredging tasks where such a possession can not be undervalued. And larger has actually ended up being JDN’s specialized.
The team collaborates with globe’s biggest routing suction dredgers, the sis ships Crist óbal Col ón and also Leiv Eiriksson with receptacle capability of almost 500,000 square feet and also deepness series of over 500 feet. JDN likewise uses 2 of one of the most effective subsea rock setup vessels, the Simon Stevin, and also the Joseph Plateau.
Advancing internal cutting
JDN stays among minority dredging firms that style and also constructs their vessels and also tools. And according to Workshop Manager, Jose Pycke, there are excellent factors for this.
“First of all, you have better control over the delivery times and there is also the quality factor,” clarifiedPycke “We produce many complex parts of unusual shapes which requires a great deal of know-how. We believe we can manufacture these complex parts best by ourselves. Furthermore, this knowledge isn’t something we want to outsource. Its best for us to maintain keep this in-house.”
More than 70 drivers operate in JDN’s manufacturing division which is separated right into a product prep work location, welding workshop and also machining workshop furnished for handling of huge components. The biggest upright turret can dealing with components approximately 18 feet in size.
Challenge and also service
In the past, JDN made components on an oxyfuel reducing maker. While the maker offered its objective, it did not consist of the capacities to prepare weld joints. This restriction presented additional time and also expense right into the procedure.
“Materials thicker than 25 mm had to be cut with much slower oxyfuel technology,” clarifiedPycke “Furthermore, we were forced to cut the bevels manually with a hand torch or an angle grinder, and that added a lot of time.”
JDN discovered that MicroStep provided a total cutting service. With about 10 x 40 feet of reducing location for plates approximately 6 inches thick and also an area for reducing pipelines with a robotic positioned along the external side of the maker standards, the MicroStep maker can refining tubes approximately 80-inch size with a wall surface density of greater than 3 inches.
The difficulty was to guarantee reducing and also placing of pipelines in the whole necessary series of sizes (regarding 4– 80 inches) and also densities and also, at the exact same time, to recommend a technological service that would certainly enable one of the most hassle-free control of pipelines while needing very little building and construction treatments on the manufacturing flooring.
The service was an oxyfuel lantern on a robot arm. This gave high motion adaptability and also was not restricted by the elevation of the gantry. This makes it feasible to position the pipeline reducing tracks and also sustaining rollers on the flooring degree without the demand to “sink it” underground.
For settlement of feasible discrepancies of the pipeline form, a laser scanner incorporated in the lantern owner is made use of to check the surface area of the pipeline where the cut will certainly be. If any kind of discrepancies are discovered, the reducing program is immediately readjusted.
The use a scanner in mix with an innovative robotic motion control (making up for the existing mistakes of the robotic’s building and construction) and also the devoted 3D camera software program mCAM gives precise openings and also shapes of various forms. The pipeline reducing area is furnished with a safety and security light obstacle that switches on along with the robotic to guarantee secure procedure.
Results
“First of all,” clarified Pycke, “because weld preparation is now done automatically and in one step, the plasma/oxyfuel cutting machine with the integrated robot arm has resulted in considerable time savings. This has also increased quality. As to the pipe cutting, not only has our reach been increased, but we can also cut any shape. In terms of flexibility, we have improved significantly.”
