unassailable ‘fit & forget’ pressure moulded cable systems for hostile environments

Capability

SMI’s capability starts with engineering expertise in mechanics, electro-optics, materials, and industrial disciplines. Our design work is based on achieving manufacturing excellence, economic efficiencies and an extensive in-house testing capability providing quality assurance of the highest level.

Our cable systems are designed for deployment in wet, dirty and hostile environments. Sealed against with our advanced thermoplastic technology they are designed for long-term installation with optimised performance and reliability.

From simple point-to-point, single patchcord connections to a series of complex distribution harnesses and bulkhead connections we can both support infrastructure design or build to print.

Achieving the best system solution does not start with services connections but with a comprehension of materials engineering, the application environment and life expectations. We have resources available that look at these considerations and our team can also walk you through the technical decision process.

SMI has strategic partnerships with a number of cable manufacturers, our design team will work with you to design the cable best suited to your application which will be made to exacting industry standards by our partners.  SMI will integrate cable and connectors into robust, sealed fit-and-forget systems.

The UK National Audit Office (NAO) criteria for assessing the value for money (VfM)

The UK National Audit Office (NAO) criteria for assessing the value for money (VfM) of government spending include ‘the three Es’: Economy, Efficiency and Effectiveness. All too often, only economy, i.e. the initial capital cost, is recognised and evaluated. In the case of submarine cable harnesses, efficiency would encompass reliability and through life cost for maintenance and replacement, and effectiveness would require systems to deliver the bandwidth, power and system support required by design throughout the life of the boat. Any erosion of efficiency and effectiveness rapidly decreases overall VfM even if economy is very strong.

The Royal Netherlands Navy is the first in the world to apply through life costing to the initial build of its new boat in the Walrus class replacement. Separation of initial capital investment and operational costs into different government funding schemes and budgets has traditionally disguised the cost of replacing failing cables, allowing poor technical selections to be made based on initial economy but carrying a lifetime of replacement burden and repair costs which fail to deliver VfM; manufacturers profiting from poor product supply.

Reliable performance from cable systems to deliver the full capacity of the systems they support will greatly increase their effectiveness. Appropriate radiographic inspection provides a further level of assurance at costs negligible compared to those associated with in-service failure and could be inexpensively introduced to support a service life in excess of 25 years.
