3.5.4 Name of destination TSDF shall be submitted to the KO at the Arrival Conference.

3.6 SFLC standard specification approved changes. The Contractor shall be aware that the following are approved changes to published SFLC 2012 Edition Standard Specifications and supersede published content:

3.6.1 SFLC Std Spec 8634, Drydocking, Appendix A, page A5, paragraph A2.7.1.3 Side Blocks: Remove formula value shown as g – Acceleration of gravity – 32.3 Ft/sec2, and replace with formula value g - Acceleration of gravity - 32.174 ft/sec2.

3.6.2 SFLC Std Spec 0740, Welding and Allied Processes. SFLC Std Spec 0740 added Appendix E, Stray Current Protection: New Appendix is posted with SFLC Standard Specifications as a separate document on internet and intranet webpage.

3.6.2.1 SFLC Std Spec 0740, Welding and Allied Processes, page 1, paragraph 1.2 Appendices: Add ‘Stray Current Protection’ to ‘Process Standard column of appendices table. Add ‘E’ to ‘Appendix’ column of

3 (Rev-0) appendices table.

3.6.2.2 SFLC Std Spec 0740, Welding and Allied Processes, page 4, paragraph 3.1.3 Stray current protection:

Add “The Contractor shall meet all requirements for stray current protection as specified in Appendix E - Stray Current Protection.” directly after paragraph 3.1.3 title.

3.6.2.3 SFLC Std Spec 0740, Welding and Allied Processes, page 4, paragraph 3.1.3 Stray current protection:

Delete paragraphs 3.1.3.1 and 3.1.3.2.

3.6.3 SFLC Std Spec 0450, Electrical Power for Contractor’s Tools and Equipment, page 1, paragraph 1.1 Intent:

Add sentence, “Note that stray current protection for welding equipment is covered in SFLC Standard Specification 0740, Welding and Allied Processes, Appendix E.” to end of paragraph.
