Safety cases bridging documents

Bridging documents are also used to create facility-specific versions of generic Safety Cases. For example, it has already been noted that the International Association of Drilling Contractors (lADC) has prepared a Safety Case template for a wide-range of drilling operations (both onshore and offshore). A bridging document can be prepared to match the needs of a particular facility to the general template strucmre. 

Confirmation Review is only mentioned in the tables of part 2. Apart from these tables there are no requirements for this kind of confirmation measure. But the objective of Confirmation Reviews is to build the bridge between other verifications as required or become necessary due to given requirements from the standard. The tables show that the key task should ensure the consistency and compliance of the norm according to ISO 26262 as well as that it is also a matter of standard compliance and work results and its documentation in defined work-products. However, most of the results also have to undergo verification according to ISO 26262, part 8, clause 9, which should show the consistency, correctness and completeness of essential work results. Essential however would be consistency checks of all work results, just like it is required later for the Safety Case. The tables label the confirmation reviews for the important work results ... 

This section also makes it clear that the primary responsibility for the development and application of a SEMP lies with the owner/operator. (The phrase owner/operator is often used in RP 75, suggesting that the two entities are the same. However, this is not always the case. Other terms that are used are lessee and duty holder.) This section also discusses the role of large contractors, their need for a safety program and the value of them developing a SEMP. The standard states, This recommended practice does not require contractors to develop a SEMP. However, contractors should be familiar with the operator s SEMP... . Reference is made to the need for bridging documents.
