Summary
Calcium chloride brine reacted with residual Sildrill in an offshore support vessel’s cargo pipework, forming blockages. Dismantling and cleaning took over a week, and four personnel required sick leave. The flash examines valve indication failure, inadequate washing procedures and missing work controls, alongside subsequent improvements to cargo awareness, washing facilities and communication.
