Abstract
The present invention is a reusable jacket base for an offshore platform having a plurality of jacket legs with an interconnecting framework. Pile sleeves are connected to the jacket legs which have a vertically extended, open-ended cylindrical member having a second stage sleeve which is connected to the jacket leg and a first stage sleeve projecting coaxially from the second stage sleeve. First and second stage locking profiles are presented inside the first and second stage sleeves, respectively. The first stage sleeve is thus accessible for cutting operations, severing both the first stage sleeve with the first pile-to-pile sleeve connection inside and the connected pile section within. This allows retrieval of the platform jacket, but preserves a second stage pile sleeve for re-deployment. Another aspect of the present invention is an improved pile sleeve adapted to facilitate reuse.
