The underwater currents hit the cable and generate vibrations at a certain frequency.

#Orcaflex viv free#

Vortex Induced Vibration (VIV)В is a phenomenon that can occur in cables in free spans and where the cables are simultaneously exposed to underwater currents. This is primarily used to provide additional stiffness at the points of interest and prevent the cable from fatigue over time. Bend StiffenersДЄ bend stiffenerВ is an aid typically attached to a cable at termination or hang off points. This is often used where the cable is hung off, terminated, suspended or in other scenarios where there is an increased risk of the cable overbending during installation. Bend RestrictorsД«end restrictorsВ are aids that are attached to a cable to prevent it from over bending. The Bellmouth are designed for easy installation, either by ROV or by divers.

BEIN supplies Bellmouths, both in plastic and steel, for use at any water depths.

In projects where the cable are pulled a shore from the vessel through a pull in pipe, it is recommended to install a Bellmouth on the sea side of the pipe, in order to ensure that the cable is not subjected to sharp edges and unnecessary abrasive wear. Such clamps are often used for cable recovery during repair of damaged cables. Clamps are designed in accordance with the customerвЂ™s preferences and needs, and they can be made ROV-friendly for easy subsea connection. Typical auxiliary aids provided by BEIN are: Cable Recovery ClampsД«EIN has experience in the design and manufacturing of clamps for both power cables and umbilicals for the oil and gas industry. Installation Aids/Products for cable installationД«EIN also has extensive experience in the design, construction and manufacturing (EPC) of aids and tools for cable installation.

Follow-up on site conducted by Project Engineer / Client Rep.

The performance of analyses for cable installation, typically in Orcaflex, and defining weather criteria based on recognized standards (e.g.

The development of specific procedures for cable installation and marine cable repairs.

Project management, planning and administration for cable installation and marine operations in general.

Seabed conditions: The seabed conditions and the topography of the seabed should be investigated in order to identify measures relating to cable free spans, overheating/reduced transmission capacity, etc.Д«EIN can contribute to the execution of projects, from project management to technical assistance.

This is due to high levels of fishing or trawling activities in the area, or the likelihood that heavy vessel anchors may hit the cable.

Need for protection: In some areas, the cable may need protection after it is laid on the seabed.

Weather buoys should be considered installed if necessary

Metocean data: Weather data should be obtained for the area, including information on waves and ocean currents.

Route survey: A route survey over the planned cable route should be conducted at as early a stage as possible.

water depth: The cable to be manufactured must be able to withstand the loads it may be subjected to during installation Typical factors that should be considered in such early studies for subsea cable installation are: The scope of the study will be governed by the complexity of the project. Feasibility study / FEED studyД«EIN can perform or contribute to initial studies to ensure an efficient installation process for land and subsea cables and define the key to a successful project execution.
