1 FUNCTION

Offshore Standard DNV-OS-F101 -- Submarine Pipeline Systems, developed by DET

NORSKE VERITAS (DNV), is a widely used standard which gives criteria and guidance on

concept development, design, construction, operation and abandonment of Submarine

Pipeline Systems.

DNV-OS-F101 CheckerTM is a set of PC software developed to check design limit state

criteria in Section 5 of DNV-OS-F101. Actually, although DNV-OS-F101 CheckerTM is similar

with some software of the same kind, it has several more features as following:

1. DNV-OS-F101 CheckerTM combines DNV-OS-F101 2000, 2007, 2010, 2012 and 2013

together. Users can choose any version as check criteria.

2. DNV-OS-F101 CheckerTM has more functions, such as buckle arrestor capacity check

and accidental load check.

3. AUTOPIPE result check. AUTOPIPE result file can be checked by DNV-OS-F101

CheckerTM directly and easily.

3 HOW TO USE

Brief procedure of running DNV-OS-F101 CheckerTM is shown as following:

1. Choose DNV-OS-F101 version

Click on the down arrow of combobox “DNV-OS-F101 Version” to choose DNV-OS-F101

version for check. Some parameters will appear or disappear according to the version user

chosen. DNV-OS-F101 CheckerTM provides 5 versions of DNV-OS-F101 for user to choose,

which are 2000, 2007, 2010, 2012 and 2013. All the versions are latest amended version.

Fig. 3.3 AUTOPIPE check

Functions of the buttons on AUTOPIPE check panel are:

“Open Case” and “Save Case”: Read and save parameters inputted for AUTOPIPE.

“Add” and “Delete”: Add or delete an AUTOPIPE section.

“Up” and “Down”: Move the position of an AUTOPIPE section.

“Rename All”: Rename all the sections as “Section X”. By double clicking the name of

section in the following listbox, user can input name for the section.

“Pre-Process”: Prepare the check worksheet for AUTOPIPE. A dialogue box will show for

user to choose an AUTOPIPE output file. Then one EXCEL sheet will be opened. After that,

a file which has the same name with the AUTOPIPE output file but an additional prefix

“Filtered-” will be generated in the directory of AUTOPIPE output file, in which unwanted

information is deleted. It should be noted that, user should set the AUTOPIPE output file as

the format in which functional load is put in the first line and environmental loads in following

lines. In sheet 1, input parameters and intermediate results will be listed. in sheet 2, all the

nodes and work case name will be listed, user should specify section number (1, 2, 3…) for

each node and specify “ULS” or “ALS” for each work case. If “ULS” is specified, then the

load values in the line of this work case will be recognized as environmental loads,

accidental loads is set as zero, load combination “a” and “b” will be checked. If “ALS” is

specified, then the load values in the line of this work case will be recognized as accidental

loads, environmental loads is set as zero, load combination “d” will be checked. After clicking

“Pre-Process”, “Calculate” button will be enabled.

“Calculate”: Run the check for AUTOPIPE, results will be calculated and showed in sheet 3

and following sheets.

The sections will show in the below box, click them, and then input the parameters for the

current section in the blue blanks in left part.
