Offshore thermal processing
Process and recycle drilling wastes at source
TWMA has recognised that as a result of the developing drilling waste management market and heightened environmental awareness within oil and gas exploration and production, the volume of wastes and the need for comprehensive waste management of these materials is increasing.
TWMA was at the forefront of the industry by taking our thermal processing capability offshore - in 2001 the TCC RotoMill was piloted in the harsh conditions of the UK North Sea. This successful trial lead to the TCC RotoMill becoming the preferred waste management option for North Sea drilling as operators quickly identified its operational, financial and HSE benefits.
The TCC RotoMill has since been adopted by the international offshore oil and gas market, driven partly by evolving drilling waste disposal legislation, but also by operators consistently adopting drilling waste management best practices wherever they work.
We provide our TCC RotoMill as part of an integrated drilling waste management solution. Once the drill cuttings leave the shakers TWMA manage the process - supplying storage, transfer and processing equipment by combining the TCC RotoMill package with our Cuttings Collection and Distribution System (CCDS).
A team of experienced TWMA personnel will run the equipment at all times. This dedicated team is also responsible for monitoring the unit performance and sampling the processed material in accordance with local legislation and TWMA best practice.
TWMA captures and treats offshore drilling waste at source by incorporating engineered offshore buffer storage units, or combining offshore treatment with partial skip and ship for large diameter hole sections as required. The recovered oil is unaffected by the process and can be immediately recycled back into the rig active mud system.
Key features
Processing drilling wastes at source will:
- Reduce the volume of wastes transported to shore
- Minimise operations associated with skip and ship methods such as vessel logistics, truck transportation and crane and forklift movements
- Reduce the overall environmental impact of drilling operations
- Minimise handling of materials
- Reduce the likelihood of environmental incidents
- Improve health and safety standards
- Reduce costs
- Return base oil to operators for reuse
Research has proven that the carbon footprint of processing drill cuttings at source offshore is significantly lower than transporting cuttings for treatment and disposal onshore.
