As our industry continues its commitment to procure oil and gas from around the world in safe and environmentally sensitive ways, IEPC is proud to offer innovative subsea safety systems to match your exploratory and production well needs.
IEPC’s subsea safety systems challenge the status quo by offering solutions that are simple and straightforward – Working with you to make deepwater safety concerns uncomplicated. By incorporating the latest advances in design and technology, the IEPC Veto™ Subsea Safety System and Electrohydraulic control system provide operators with the comprehensive subsea well control that’s required in today’s highly demanding and regulated deepwater environments.
Subsea LNG Cryogenic Pipeline
The IEPC LNG pipeline technology uses a highly-efficient thermal nano-porous insulation in the annular space, between the inner and outer pipes, and this material is kept in an ambient pressure environment. The nano-porous insulation is hydro-phobic, in that the pour spaces are smaller than the molecules of water; therefore, the insulation does not absorb water. In addition, the insulation does not degrade in the presence of water or moisture, an important consideration for thermal efficiency and for operational maintenance. One novelty of the present IEPC LNG pipeline technology is the application of high-strength 9% Ni alloy steel pipe, metallic bulkheads and spaces to cryogenic product pipelines. As a result, the pipeline bundle configuration is a structural element, which addresses the thermal contraction and expansion loads, without resorting to expansion bellows or ultra-low thermal contraction alloys.
IEPC's Subsea LNG pipeline technology focuses on providing the following solutions to IEPC's Offshore Clients:
Subsea Pipelines and Flow Assurance
- Lower costs to build,
- Better reliability,
- Resistant to water ingress,
