Like every company, we’re in business to make a profit. But not at any expense. And certainly not at the expense of our employees, assets, the environment and communities. So how do we work? What principles do we live by? We covered them all in our recent Health and Safety Day. See for yourself by watching the video.

Five Types of Terminations

DeRegt works with each individual client to provide the perfect cable solution for their specific requirements. Each cable system by DeRegt is custom-made and this does not only apply to the cables themselves, but the terminations as well. DeRegt is able to design the termination to adapt to specific circumstances and to think outside the box to find the right solution for every situation. From deep undersea to high in the sky, terminations can be grouped into a few types which share similar features.

An unusual request from 200km off the Norwegian coast- an interview with Aker Solutions

Aker Solutions came to DeRegt with an unusual request. Aker is responsible for the maintenance of a floating concrete tension-leg platform, installed over a subsea template with 56 well slots. The rig is named Heidrun, and produces oil and gas from a depth of 2,300 metres. It is located about 200 km off the middle of the Norwegian coast. The unusual question was: can you reverse-engineer the same cables from 25 years ago, as a replacement for the next 50? We spoke to Roger Sand at Aker Solutions to find out more about this unique project.

Blue Nodules: harvesting at 5.5km depth

The EU aims to reduce dependency on imports of raw materials. Large quantities of raw materials can be found in deep sea Polymetallic Nodules. Polymetallic Nodules contain relatively high concentrations of Nickel, Copper and Cobalt. Cobalt is especially valuable to harvest since it is used in batteries for electric cars. Nodules occur at any depth, but the highest abundance has been found between 4,000 and 6,000m. How do you harvest these nodules at such a large depth?DeRegt was asked to join an EU funded consortium of 14 companies. Industry, research institutes and service companies across seven different countries joined hands to solve the question on how to harvest them, avoiding serious harm and minimizing the environmental risks.

How does DeRegt get cable buoyancy just right?

Feb 22, 2019 12:07:45 PM / by Maurice Corveleijn posted in ROV, ROV Cables, Whitepaper

0 Comments

Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object. If an umbilical cable is too light it will pull an ROV up, which makes piloting fiendishly difficult when manoeuvring through offshore structures. If the tether is too heavy it will push the ROV down making delicate work impossible. So how do we make sure we get it just right? Find out how we are able to test down to a single gram, up to 200 bar.

How do we prevent dangerous overheating in your cable?

When working with cables in shallow water, relatively less of the cable will be submerged while the rest of it is wound on a drum on the vessel. In deep water applications, where relatively more of it is deployed, water provides a cooling effect for the cable when it is subjected to electrical currents. In contrast, in the shallow water applications, layers of cable are spooled on a drum on the vessel and these layers are unable to benefit from the cooling effect. Eventually, the heat caused by the electric current flowing through the cable builds up.

Driven by solutions: Phil Roscoe on the new future-proof extrusion room

Feb 1, 2019 11:08:35 AM / by Phil Roscoe posted in ROV, ROV Cables, News, Change, Production

A central component of our cables is a stranded copper wire, which is able to conduct electricity. Around it we extrude a continuous layer of plastic to isolate the copper from its surrounding environment. Twisting this together with other components, forms our custom designed cable.

The plastic has to be a good insulator and thick enough to prevent the copper from shorting to the outside world. Many of our cables operate in deepwater under high pressure, so we need to make sure that our insulation is sturdy enough to keep the water out. Contamination in the plastic will cause the insulation to deteriorate over time and eventually fail.

Why do we need Flexible Terminations?

Oct 24, 2018 2:45:17 PM / by Jeroen Romijn posted in Naval Defense

0 Comments

Space is always scarce on board ships and submarines in particular, which means that the smaller Sonar or ROV systems can be, the better. A tailor-made cable with a small diameter and bend radius helps keep the winch as small as possible, reducing the overall footprint of the system. A logical step you can take to reduce system size is opting for a flexible termination for towed arrays, with the same bend radius as the cable, as this allows the entire rig, including both the cable and the array, to be rolled up on the same winch.

The demand for UAVs, UUVs and USVs for defense purposes is currently greater than ever, which means that crucial components, such as cables, have to be developed quickly and must meet high-quality specifications.

 

As a leading cable supplier in the field of Naval Defense applications, we have identified an increasing demand for new, innovative cable systems for various unmanned vehicles that can be used in combat and reconnaissance operations.
