XPATH: Select ements whose parent-element have a child-element with the name "x" containing the value "y"

I have the following XML Instance and need to find the XPath Statement for: All "name" elements whose parent-element ("norm" elements) have a child-element named "Keyword" containing the value "Engines"

<?xml version="1.0" encoding="UTF-8"?>

<norms>

    <norm id="1" normid="2">
        <Name id="3">EN ISO 13857</Name>
        <Keyword>Security</Keyword>
        <Keyword>Engines</Keyword>
        <ReplacementFor></ReplacementFor>
    </norm>

    <norm id="2" normid="1">
        <Name>EN ISO 13849-1</Name>
        <Keyword>Security</Keyword>
        <Keyword>Engines</Keyword>
        <Keyword>Controlling</Keyword>
        <ReplacementFor>EN ISO 13857</ReplacementFor>
    </norm>
