18.5 International Electrotechnical Commission Safety Assessment
International Electrotechnical Commission (IEC) 61508 is an international standard that
describes a standardized approach to Asses the functional safety of electric, electronic,
and programmable electronic safety-related systems. This standard is based on a life-
cycle evaluation of system reliability and safety level determination. Safety integrity levels
are categorized as SIL1, SIL2, SIL3, and SIL4. Levels are established by assessing the
potential for personnel injury, equipment damage, and environmental damage. The
installation site design and operating requirements will determine the applicable SIL level.
Solar can provide reliability data on its equipment to assist customers in their overall
safety assessments.
18.6 Offshore Marine Applications
For installations that require offshore marine certification, Solar conforms to the rules and
standards established by certification authorities and/or customer specifications.
Certification can be performed by one of the following authorities:
• Det Norske Veritas (DNV)
• American Bureau of Shipping (ABS)
• Lloyd’s Register (LR) of Shipping
• Bureau Veritas (BV)
Solar can provide certification or provide supporting information to permit certification by
another party.
18.6.1 Det Norske Veritas Certification
Det Norske Veritas (DNV) certification includes design verification and a manufacturing
survey. DNV witnesses the fabrication and testing of engines and packages. Operations
witnessed by DNV are defined in the inspection and test plan (ITP) that is prepared by
Solar’s Quality department and approved by DNV at the beginning of a project.
To eliminate redundant inspections, Solar has established a manufacturing survey
arrangement (MSA) with DNV for a specific group of products. This MSA is based on a
DNV audit of Solar's Quality System. The MSA authorizes Solar to carry out a specific
level of inspections and tests without the presence of a DNV representative.
18.6.2 American Bureau of Shipping
The American Bureau of Shipping (ABS) performs design appraisals and inspections.
Typically, ABS certification is performed according to ABS “Guide for Building and
Classing Facilities on Offshore Installations,” 1991. ABS certification of Solar's gas
turbines is based on compliance with the American Petroleum Institute (API) Standard
616, with standard exceptions.
18.6.3 Lloyd’s Register of Shipping
Typically, Lloyd’s Register (LR) of Shipping performs design appraisals and
manufacturing surveys. LR recognizes engine type approvals provided by DNV. LR’s test
and inspection witness points are defined in the project Inspection and Test Plan (ITP).
18.6.4 Bureau Veritas
Bureau Veritas (BV) performs design appraisals and manufacturing surveys. Typically,
BV certification is performed according to BV publication “Floating Production, Storage
and Offloading Units Ch 10 NR456 April 1998.” Certification of Solar's gas turbines is
based on compliance with the American Petroleum Institute (API) Standard 616, with
specified exceptions.
