The invention relates to a device for severing tubular members, such as piles of an offshore platform. The device is incorporated into a platform pile as one of the sections of the pile and is deployed below a mudline during installation of the pile. A shaped charge mounted in that section remains unloaded during the useful life of the platform. An explosive material is delivered into the shaped charge through conduits immediately prior to severing the pile when the platform needs to be removed.
