MTR 100: Teledyne Marine Interconnect Solutions

Posted by Irina Tabakina

Describe the companies in your group, citing examples of your group collaboration.
    Teledyne Oil & Gas consists of Cormon, DGO, Impulse, PDM, ODI, Storm Cable  and VariSystems. This synergistic collection of product lines formed from Teledyne companies with 13 locations around the globe. They work in symphony to provide a broad range of power and data transmission interconnect solution options from terrestrial and topside applications to littoral and deep ocean environments. Applications include demanding explosion proof systems, dry-mate submersible instrument and vehicle harnesses, high differential pressure penetrations, and connections to wet-mate electrical and hybrid jumpers for high reliability long performance life in deep ocean.
In a single ocean observatory distributed sensor network, the Teledyne Oil & Gas organization via the Teledyne Marine Interconnect Solutions (TMIS) vertical market provides the backbone for power and communications transmission enabling interconnect from the shore station all the way through to the most remote deployed sensors in the system. This begins with shore station equipment networking cable and molded harness assemblies, moving to the cable termination assemblies at the backbone to power node junction. The TMIS kit in the CTA moves the raw power and optical through the power and optical conditioning equipment with high reliability subsea wet-mate power connectors and wet-mate optical connectors and provides the transmission capability at the output into the network.  The wet-mate hybrid connections on the back end of the CTF provide the sole path of power and communications out to the secondary nodes or SIIMs (Science Instrumentation Interface Modules) allowing for long distance data transmission to a network of modularly expandable sensors deployed in wide area networks on the ocean floor in deep water.  These science instruments are powered through dry-mate submersible to wet-mate Ethernet transmission jumpers that allow for the wet configuration that enables high bandwidth data transfer and unlimited reconfiguration, upgrades, and modular expansion.   One hundred percent of the world’s modern ocean observing systems are using Teledyne Marine Interconnect Solutions technology.  The reliability is driven by the partnership between Teledyne Scientific Corporation (formerly Rockwell Scientific Materials Laboratory) and the Teledyne Oil & Gas Technology Development Center to meld science and engineering practice. Together they design and verify long performance life reliability through a structured program of qualification of materials systems, component designs and systems exposed to combined stress analysis in simulated ocean conditions to provide accelerated aging life performance metrics. All are tested to failure to create a true understanding of the mechanisms, time and conditions to create robust solutions for high reliability survival in harsh environments.  In addition, the harsh operating environment of the deck systems and the ROV deployment vehicles and systems themselves require high reliability interconnect harnesses to power and transmit data to and from the many instruments in the deployment operations.  

What is your group’s most exciting technology advancement since MTR 100 2013?
    The size, breadth and depth of the world’s oil & gas production fields, along with the need for more advanced communication from the expanding network of health management sensors, has driven an investment in new product development at Teledyne Oil & Gas. Our solutions focus on complex challenges for subsea power and data transmission to meet new requirements for enhanced oil recovery and subsea processing capabilities.  The ocean science community directly benefits from the technology outputs funded by the major oil & gas operators.  The most exciting recent examples of this new technology include the development of “Active Flying Leads” which describes an expanding family of ruggedized wet and dry-mate jumper assemblies that can expand the length of sensor deployments beyond the ranges available just a few short years ago. This is achieved through the use of a qualified set of subsea repeater systems and miniature subsea media converters combined with  application specific cabling for high integrity data transmission across very long distances.  E2FL (Extended Ethernet Flying Leads) surpass the length of deployment distances for reliable Ethernet transmission from the 70 meters available just years ago to a full 100 meter lengths using special Ethernet cables.  Up to 300 meters is accomplished by using recently qualified repeater systems and to a distance of up to 10 kilometers using recently subsea qualified miniature E/O media converters in symphony with electrical Ethernet connectors and  hybrid cable systems.  CAB Bus transmission systems are available  in similar configurations designed to follow the qualification path and utilizing component housing developed for the Ethernet systems.  These advances enable ocean bottom instruments to be deployed at great distances from the SIIMs and nodes to allow scientists to observe organisms in an environment free of the distractions of manmade structures, a reality that has frustrated scientists for many years in this market.

What market trends are fueling your group?

    Our primary market, oil and gas production and exploration is driving trends for higher subsea power and more advanced levels of data transmission due to emerging legislation requiring higher yields for production from existing fields in order to earn new leases.  These conditions introduce challenges that until recently were determined as too expensive to feasibly tackle.  Increased production yields requires a greater understanding of the evolving conditions of  the reservoirs, which in turn demands greater and more capable sensors, such as dense networks fixed seismic life of field networks, requiring more transmission bandwidth. Additional challenges for maintaining and increasing pressure in the well reservoirs, is driving the need for  high power subsea motors and pumps to re-pressurize the wells to increase production flow.  These systems require high power wet-mate connectivity for long life reconfiguration and high pressure differential / high temperature differential penetrations in order to make meeting these new requirements possible.

Teledyne has grown tremendously in recent years via acquisition, a strategy we have covered in our pages previously. What are the advantages? What are the challenges?
    The benefit provided through the Teledyne Marine Interconnect Systems and Teledyne Oil and Gas is the synergy delivered through a cohesive group of aligned product lines that provides a powerful level of reliability and security of supply to our customer community.  The ability to construct a contract with a single PO, with a single set of terms and a single warranty across a mix of what was once seven companies requiring separate contracts and contract management is a powerful differentiator for our customer base.  Simply having a total interconnect harness consisting of components from a single organization is a concept unheard of just five years ago. It lowers operational risk and reduces instances associated with assigning warranty that have until now been a nuisance and a normal fact of life.  The immediate access to broad levels of expertise in technology available through the expansive network of Teledyne companies in and beyond the market place is very powerful in identifying and generating engineered solutions to complex challenges for our customer base.   The challenges are manifested in maintaining the lines and aisles of communication between Teledyne consolidated business units and the teams that are calling on the same customer base offering various and differing parts of an overall solution. At Teledyne, we are investing in awareness training and networking among the teams to understand how to recognize applications where our sister organizations have technology and skill sets that are a match to our customers challenges.  We grow better in this area each and every day through combined exhibits at conferences, cooperation with presentations at sales and technology training events and through friendly camaraderie.
