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 Checker TM 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 Checker TM is similar with some software of the same kind, it has several more features as following: 1. DNV-OS-F101 Checker TM combines DNV-OS-F101 2000, 2007, 2010, 2012 and 2013 together. Users can choose any version as check criteria. 2. DNV-OS-F101 Checker TM 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 Checker TM directly and easily. 1

Click Open Case or Save Case tool button to read the parameters from case file or save the parameters as a case file. 4. Calculate Click Run tool button to run the check calculation. One of the EXCEL sheet will show in the right side of interface and the check result will show in the sheet. 5. AUTOPIPE check Click Show AUTOPIPE Panel checkbox, then AUTOPIPE check panel will appear at right side. 4

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 5

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. 6
