A global seabed with a constant slope can be optionally defined for composite cables, using a reference point and the angle and direction of maximum slope.

| (2) This is a point on the seabed. |
| (3) This is the direction of greatest slope relative to the global X-axis, using the same convention as for wind and current direction. |
| (4) Global seabed slope must be not less than zero and not greater than 30°. A positive slope is up in the direction given by (3). The local seabed slope definition for any structure-anchor composite cable using the COMP data record will be ignored if a SBED data record exists. |
