The Oil, Gas & Chemicals department provides a comprehensive service to clients involved in the international trade of oil, gas and chemicals and bulk liquid cargoes by sea, pipeline, rail and road.

Bulk liquid cargoes encompass the shipment of crude oil, petroleum products, petrochemicals, liquefied gases, as well as vegetable and animal oils.

Oil and petrochemical plants are high-capital, major hazardous installations, which impose large loss potentials. Safety and pollution issues are of paramount concern, whilst quality issues dominate and contamination claims constitute a prevalent risk.

CWA also provides expertise in loss prevention, risk, safety, and environmental protection.

CWA Experts & Consultants

Typical Cases

Gas plant

CWA has conducted numerous in-depth investigations and loss prevention surveys following recurring problems in the carriage of LPG involving for example excess water content, and the presence of excess dimer in butadiene shipments.

Clearing up after spillage

CWA regularly makes international attendance to investigate quality deviations in bulk liquid cargoes petroleum products, petrochemicals, and vegetable oils.

Oil refinery

CWA has dealt with a number of large refinery Business Interruption (BI) claims arising from problems in the feedstock supply and/or quality, or from fire and explosion incidents. Often investigations require thorough knowledge of refining practice.

Corrosion of tanker hull

Concerning fitness of vessel's tanks and tank coatings for carriage of aggressive bulk liquid cargoes.
