DeepOcean use Dieseko equipment for Chestnut Oil Field related subsea decommissioning project

DeepOcean has selected Dieseko to support the subsea decommissioning of the Chestnut Oil Field Wellhead Protection Structure.

The Chestnut oil field is located in block 22/2a of the UK Continental Shelf in the North Sea, nearly 200 km east of Aberdeen, and is owned by Spirit Energy and Dana Petroleum. Chestnut first came on stream in 2008 and was only expected to produce 2 years. However, it has exceeded its life expectation multifold due to additional investments made, before the decision was finally made to remove the well.

Scope

The focus for decommissioning of the wellhead protection structure will be on retracting the Anchor Tech piles holding this structure to the seabed. Dieseko will supply their 1412C Vibro Hammer, 320TU Clamping System, 900 Power Pack and hose reel.

All will be supported by Dieseko’s experienced offshore technicians taking care of (de)mobilization, site acceptance testing and operation & maintenance throughout the project.

By removing all embedded piles from the seabed Diesoke is contributing to the reuse of steel, reduction of the carbon footprint and promotion of sustainable practices offshore.  Source: Dieseko
