The Djuvik Lightweight Debris Cap is used to protect the subsea wellhead and connector.
The LWDC functions as both a cap to prevent debris from entering the wellhead and XMT and as a preservation cap to prevent degradation and corrosion of the connector. If the LWDC is installed on a new type XMT (with TH and 2 plugs and no Internal Tree Cap), the LWDC has a secondary function of locking down the TH during the production of the well.
