Connection Types

The available connection types are defined in the Account under Connection Types. By default, the following connection types or systems are defined:

  • None
  • Straight Line
  • Riser – Lazy Wave
  • Riser - Catenary
  • Jumper – Horizontal Z
  • Jumper – Vertical M
  • Jumper – Vertical N”

The Riser Generation and Jumper Generation sections further down describes the more special Connection Types that have additional settings and design parameters. The connection system options differs based on if you have connected topside to subsea asset (Riser), or subsea to subsea asset (Jumper).

None

This is the default connection type, which is undefined and is a regular spline construct that can be freely edited by the user by adding new connection points to the spline for curvature adjustments.

Straight Line

This connection type will force the connection to be a straight line only. You will not be able to add new connection points!

Riser Lazy Wave

To create a lazy wave riser, you start with connecting your desired topside asset (FPSO, semi sub etc.) to your subsea asset e.g. riser base, SSIV, or similar. Or select a connection that is already created. This will bring up the Connection Attributes section in Project View as shown below:

Alt text

Then in the Connections tab you select the Connection drop down menu and pick Riser - Lazy Wave.

Alt text

This will then display the riser properties for Lazy Wave riser generation.

You will now see that three (3) riser control points are generated on the connection in 2D View. The Riser points are named a, b, and c. In 2D View you can adjust the position on these control points on the connection. To control the Z value (depth) of the curvature points (A, B, and C) use the corresponding depth numerical input fields, including adjusting the offset for each curvature point. You can see the illustration below for more detail:

where the input fields are:

  • Depth - The numerical depth value (Z value) for each of the riser control points. The value range will be down to the sea bed level defined by project settings or loaded bathymetry.

  • Offset - The numerical offset value for each of the riser control points. The value range will is between 0.00 and 1.

Note! Control point C is the touchdown point.

Once you are satisfied you can then switch to 3D view to see your riser creation as shown here:

You can of course also import risers from Engineering programs such as OrcaFlex through the Create Connection from File option.

Riser Catenary

To create a catenary riser, you start with connecting your desired topside asset (FPSO, semi sub etc.) to your subsea asset e.g. riser base, SSIV, or similar. Or select a connection that is already created. This will bring up the Connection Attributes section in Project View as shown below:

Alt text

Then in the Connections tab you select the Connection drop down menu and pick Riser - Catenary. If you do not see this selection in the menu, you will need to create it first in the Account Settings under Connection Settings

Alt text

This will then display the riser properties for Catenary riser generation.

Alt text

The catenary riser generation is formula based where the input fields are:

  • Sub-merged Weight - The numerical depth value of the submerged weigth of the riser.

  • Top Angle From Vertical - Top angle in degrees.

Once you are satisfied you can then switch to 3D view to see your riser creation as shown here:

You can of course also import risers from Engineering programs such as OrcaFlex through the Create Connection from File option.

Jumper Generation

To create a jumper, you start with connecting your subsea to subsea asset e.g. XMT to a Manifold. Or select a connection that is already created. This will bring up the Connection Attributes section in Project View as shown below:

Alt text

Then in the Connections tab you select the Connection drop down menu and the following options becomes available:

Alt text

At the moment you can select between; Jumper - Vertical M, Jumper - Vertical N, and Jumper - Horizontal Z. Select the one you wish to use e.g. Jumper - Vertical M as shown here:

Alt text

Jumper Vertical M

This jumper type has a set of parameters to adjust the jumper design to compensate for scenarios where the connected assets might be on different seabed elevation. See the illustration below:

Alt text

You have now the following jumper edit points for Jumper Point a and Jumper Point b as shown here and exaggerated for illustration purposes:

Alt text

  • Distance - Adjust the numerical value for the distance up and down for the segment shown in the illustration above.

  • Heighest Height Offset - Adjust the numerical value for the highest height offset up and down for the segment shown in the illustration above.

  • Lowest Height Offset - Adjust the numerical value for the lowest height offset up and down for the segment shown in the illustration above.

  • Length - Adjust the numerical value for the length up and down for the segment shown in the illustration above.

The Jumper Point b values are identical for the other side of the M Jumper Connection.

Jumper Vertical N

This jumper type has a set of parameters to adjust the jumper design to compensate for scenarios where the connected assets might be on different seabed elevation. See the illustration below:

Alt text

You have now the following jumper edit points for Jumper Point a and Jumper Point b as shown here and exaggerated for illustration purposes:

Alt text

  • Distance - Adjust the numerical value for the distance up and down for the segment shown in the illustration above.

  • Heighest Height Offset - Adjust the numerical value for the highest height offset up and down for the segment shown in the illustration above.

The Jumper Point b values are identical for the other side of the N Jumper Connection.

Jumper Horizontal Z

This jumper type has a set of parameters to adjust the jumper design to compensate for scenarios where the connected assets might be on different seabed elevation. See the illustration below:

Alt text

You have now the following jumper edit points for Jumper Point a and Jumper Point b as shown here and exaggerated for illustration purposes:

Alt text

  • Distance, Direction Axis - Adjust the numerical value for the distance length for the segment shown in the illustration above.

  • Distance from Middle Point, Side Axis - Adjust the numerical value for the side offset for the segment shown in the illustration above.

The Jumper Point b values are identical for the other side of the Z Horizontal Jumper Connection.

Connection Segments

This feature allows you to add segments to connections meaning that you can define a connection to be comprised of multiple segments. This could be used to e.g. assign segments of a connection for indicating rock dumping, trenching, or if a connection is assembled with different types of materials e.g. parts of a mooring line could be chain etc. You define these in the Account Settings->Connection Segments.

When you have selected a connection on stage, you will find the follwing option in the connection section in project view as shown here:

Alt text

Press the Add button to add a segment to the connection.

And the new segment will then be displayed on the selected connection as shown here:

Alt text

You can click to select the segment on the connection. Doing so will display the cross hair edit points as shown below:

Alt text

Clicking while holding down the left mouse button on the segment will allow you to move it along the connection to the desiered position. If you click one of the cross hair selectors you can increase or decrease the segment length from that point.

In Project View you will then see a new segment entry appear under the selected connection as shown here:

Alt text

Selecting a segment under the connection entry will then display the segment property panels "Common", "Segment", "Logs" and "Metadata" if thats is defined under Account Settings->Connection Segments.

Common Tab

The Common Tab is comprised of all the available standard segment settings for selected segment(s):

Alt text

Tags - Every segment can be tagged which makes it easy to group selections. See Tags section for more information.

Name - To name a segment simply enter the desired name in the text edit box.

Opacity - The Opacity slider allows you to define the segment transparency value from 0,1 to 1. Where a value of 0.1 is fully transparent and a value of 1 is completely non-transparent.

Segment Tab

The Segment Tab is comprised of all the available specific segment settings for selected segment(s):

Screenshot

Type - If you have defined connection segment types in the account setting this drop down list will allow you to select the segment type. Please see Account Settings->Connection Segments.

Relative to end - Check this box if the selected segment is relative to the connection end point.

Offset - You can enter a numerical offset value from the connection end point to adjust the segment start point here.

Length - You can enter the numerical value for the length unit here.

Thickness - You can also choose the sgement line Thickness or Width on an individual segment by entering the desired numerical value in the edit field to the right.

Meta data tab

If you have created associated metadata with the Segment Design Type under account settings, you will have the associated Metadata property panel:
