Protecting highly inaccessible subsea equipment demands deep understanding of the ocean environment and the engineering challenges of operating subsea and at depth. Njord by Trelleborg is a unique series of polymer solutions engineered with decades of offshore industry insight to provide flexibility, buoyancy and protection solutions to the toughest subsea challenges.
In floating production scenarios, pipelines such as flexible risers, cables and umbilicals are often required to be held subsea in specific geometric configurations designed to prevent over utilization of the system
A pipeline laying operation may have a requirement to simultaneously lay a small diameter service line or umbilical. During the installation, to ensure that the secondary lines are adequately supported between surface and seabed, they may be attached to the main pipeline using a clamp arrangement.
Njord Guide are solutions that are designed to allow any flexible or rigid line or multiple lines to be centred or to be sealed, in a I-Tube, J-Tube, Tunnel or large diameter pipe.
With an ever increasing global requirement for data and product transfer, and the necessity for transfer networks to run through ever harsher environments, the demand for highly advanced cable and flowline protection grows
Thermal insulation is necessary to avoid formation of hydrate plugs and wax build-up in subsea structures. The build-up begins when the oil/gas composition temperature is not maintained and begins to cool. Without thermal insulation the cold seawater rapidly cools down the oil, forming hydrate/ wax blockages making it impossible for a safe flow
