Specification of neutral or real top soil load (overburden) along pipeline axis (Input Table)

Data description/conditions:

Identifier: (toggleable)

Identification name of data reference point

Required

NB1:

Neutral or real top soil load on pipeline just before and at X-P reference point

≥ 0.

UNCF1:

Uncertainty factor for soil parameter NB1

≥ 1. / Undefined if NB1=0.

[Default: 1.1]

(The use of UNCF1 is according to U-RVT, specified in table UNCER.)

LOADF1:

Load factor for soil parameter NB1

> 0. / Undefined

[Default: 1.0]

(If specified, NB1 is multiplied by LOADF1.)

NB2:

Neutral or real top soil load on pipeline just after X-P reference point

≥ 0. / Undefined

(If NB2=UNDEFINED it is assumed NB2=NB1)

UNCF2:

Uncertainty factor for soil parameter NB2

≥ 1. / Undefined

(If UNCF2=UNDEFINED it is assumed that UNCF2=UNCF1. The use of UNCF2 is according to U-RVT, specified in table UNCER.)

LOADF2:

Load factor for soil parameter NB2

> 0. / Undefined

(If specified, NB2 is multiplied by LOADF2. If LOADF2=UNDEFINED it is assumed that LOADF2=LOADF1.)

(NB values including uncertainty factor shall not be greater than the related RVT values. In case there is no soil NB shall be 0.)
