Lightweight Debris Cap

The Djuvik Lightweight Debris Cap is used to protect the subsea wellhead and connector.

The Djuvik 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 Lightweight Debris Cap is installed on a new type XMT (with TH and 2 plugs and no Internal Tree Cap), the Djuvik LWDC has a secondary function of locking down the TH during the production of the well.

The Djuvik Lightweight Debris Cap is constructed using PA6 Nylon. The main advantage of this is that it will expand the lifespan of both the Debris Cap and the connector. Due to the difference in materials, the LWDC will never damage the connector. Likewise, the Djuvik Lightweight Debris Cap will never be affected by corrosion. 

Weighing in around 15-20 kg. when submerged the cap is easily operated by ROV. This gives the customer the possibility to perform installation and removal without having the rig or vessel in position above the wellhead, thus contributing to saving rig hours and emissions.
