Semi-Submersible To Get Offshore Waste Recycling System

Oil and gas environmental waste contractor TWMA is to install and operate its offshore waste recycling system on the Stena Spey semi-submersible drilling rig working in the UK North Sea for Chevron.

Ronnie Garrick, managing director of TWMA, said: “Using TWMA’s environmentally sensitive TCCRotoMill and CCDS system will allow Chevron to contain, reuse and recycle drill cuttings on-site, which increases efficiency and improves environmental performance offshore by removing the need for skip and ship operations and reusing the recovered oil in the drilling fluid.

The TWMA TCCRotoMill and its mobile counterpart, the TCCRotoTruck, are thermal cuttings processing units that recycle drilled cuttings by breaking them down into oil, water and solid components for reuse.
