ELECTRICAL INTEGRITY AND INSULATION RESISTANCE MANAGEMENT
The electrical integrity of umbilicals, cables, connectors, and distribution equipment has proven to be a real cause of concern with subsea controls equipment. Problems can often come to light soon after installation, and even if the electrical performance is good in the early years, industry experience suggests that often problems will manifest themselves as the equipment ages. Add to this the fact that normal fault finding by process of elimination is extremely expensive, and that the diagnostic intervention itself can cause further damage to non-recoverable parts of the system, and it is clear there is a need to understand, monitor, and manage the integrity of subsea electrical power and communications systems right through the life of the asset from design to decommissioning.
Viper Subsea has extensive practical experience, theoretical knowledge and analysis tools to be able to predict, and mitigate against failures as well as implement long-term condition monitoring programmes. Services offered include:
- Review of system design and acceptance requirements for maximum integrity of new equipment
- Redesign of inter-connection systems to improve in-field reliability
- Long term trending analysis of umbilical and subsea apparatus for electrical integrity
- Predictive trending analysis to forecast time until system failure
- System modelling to define minimal operating Insulation Resistance (IR) levels
- Recommend operational changes to alleviate impact of loss of integrity and so extend life expectancy of distribution equipment
- Preparation of intervention procedures and equipment maintenance plans for fault finding and repair.
- Supply of replacement equipment and spare parts.
