Marine-Certified Cables Improve Safety and Reduce Time to First Oil

In the marine industries the high profile DeepWater Horizon disaster (also known as the Macondo blowout) and increasing government regulation have led to a new "culture of safety". Part of this new outlook is a demand for products that are people and environmentally friendly, especially when things go wrong.

In response, last fall we announced the availability of our new MarineTuff line of HaloarrestXLink LSZH-jacketed instrumentation, control and VFD cables. These cables have been certified by the American Bureau of Shipping (ABS) to their highest standards for marine use.

Besides high safety characteristics, marine-certified cables provide other benefits, including faster "time to first oil", a metric that is used for new oil production projects. Let's consider what makes a cable safe and how such a cable can speed up large complicated oil system projects.

Making Marine Cable Safe

There are two primary safety concerns when it comes to cables. The first is to make sure that the cables perform reliably when exposed to extreme heat or hot oil. Think about it…the signal that controls critical operations needs to get through in order to safely operate, or in the event of any emergency, safely shut down the process. The second concern is to make sure that if a fire consumes the cable, they do not emit any toxic fumes that would harm people in the area.

To address the first concern of reliable performance, Belden MarineTuff cables have thermoset jackets that do not melt at any level of heat and that can be exposed to hot oil. There are two jacket options:
  •     A jacket that can be exposed to oil at temperatures not in excess of 60?C.
  •     A jacket that can be exposed to oil at temperatures not in excess of 75?C.
These features result in marine-certified cables that can withstand the harshest offshore environments. Furthermore, if a fire occurs in the confined spaces of offshore rigs, or any kind of marine vessel, people and sensitive equipment are protected from damaging acid or smoke.

Like all of our copper Ethernet cables, these products come with Belden's patented Bonded-Pair technology, a design that bonds individual conductors. This assures an extremely uniform spacing between each twisted pair, a key factor for consistent electrical performance. It also helps the cables maintain physical integrity and good functioning when routed around and through tight passages.

Bonded-Pair cable is worth knowing about because the majority of industrial network failures occur due to signal transmission issues. An hour of network downtime on a major deepwater offshore facility can cost more than $1 million USD (10,400 barrels of oil at USD $90.00 per barrel).

To address the second concern of cables not emitting toxic fumes in the event of a fire, our new certified cables are what is known as "LSZH" or Low Smoke Zero Halogen . This means that the cable does not contain a commonly used component called halogens (hence they have the text "Haloarrest" in their name). Examples of halogens are fluorine, chlorine and bromine.

If a fire occurs, LSZH cables do not produce acid when burnt and combined with water, and they do not emit toxic fumes.
Improving Oil Project Returns with Marine-Certified Cable

How can a cable improve financial returns? Obviously keeping the network up and running, as described above, is one way.

Another way is to reduce the time and effort required to certify systems, thus helping to complete a project faster. All offshore signal transmission systems require certification by the relevant regulatory bodies. Historically, this has been a cumbersome process requiring substantial customer engineering, design, procurement and installation resources.

With cable that is certified out-of-the-box operators, contractors and suppliers reduce costs or improve profit margins. Plus, speedier project completion leads to faster time to first oil.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications. The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications. “We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner E

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs. The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs. Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these p


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference. The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection. The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
