Weatherford Global Products Ltd v Hydropath Holdings Ltd & Ors

Manufacturers of equipment for potentially explosive atmospheres must address foreseeable operating conditions and reasonably anticipated misuse, including risks arising outside the equipment itself. Contractual compliance with ATEX requirements therefore required the product to prevent, contain or otherwise accommodate foreseeable incendive sparking in surrounding pipework.

Where the contractual purpose included use in Zone 1 and Group IIC environments, warranties of fitness, conformity and compliance were breached by a product capable of producing dangerously excessive spark energy. Contractual rights to develop improvements permitted efforts to contain or prevent the risk. The court also applied the ordinary tests for breach of confidence, inducing breach of contract, directors’ duties and abuse of process.

Weatherford supplied and distributed Hydropath’s electronic scale-prevention products for oil and gas installations under a Supply Agreement, Licence Agreement and Technical Services Agreement. The products were marked and certified for hazardous Zone 1 environments, including Group IIC atmospheres.

After field incidents and independent testing demonstrated that foreseeable short-circuiting could produce incendive sparks, Weatherford claimed breach of contractual warranties concerning fitness for purpose, conformity with specifications and compliance with applicable requirements. Hydropath and Clearwell counterclaimed concerning confidential information, the Clearwell name, inducing breach of contract and directors’ duties. The central issues were whether the products were contractually and technically compliant, and whether the counterclaims were established.

1. Weatherford’s claim succeeded on liability. The Clearwell Products supplied before late 2009 were unsafe for use in Zone 1 and Group IIB and IIC atmospheres. They were not fit for purpose, did not conform to the Supply Agreement specification and did not comply with the ATEX Directive, the ATEX Regulations and relevant standards.
2. The contractual and regulatory requirements concerned integrated explosion safety. A manufacturer had to take account of every relevant electrical source of ignition, reasonably anticipated misuse and actual or foreseeable surrounding-area conditions. It was insufficient to argue that the equipment itself was compliant while adjacent pipework could become a source of incendive sparking.
3. The parties’ contractual understanding and the product markings established that Group IIC use was within the intended purpose. The Clause 9 warranties therefore required products capable of safe operation in Group IIC environments. The evidence showed that short-circuiting on either side of the ferrite ring could occur over substantial distances and could generate spark energy far above safe levels.
4. Instructions requiring insulation, painting or switching off the product did not remedy the inherent defect. They did not reliably prevent short-circuiting, were not always practicable and could not address unplanned or foreseeable events. The inaccurate Group IIC marking was itself a breach.
5. The confidentiality counterclaim failed. The alleged information had not been shown to be confidential or misused, and the evidence did not establish copying. Weatherford was in any event contractually entitled to develop improvements, including systems designed to contain or prevent sparking.
6. The claims concerning the Clearwell name, inducing breach of contract and directors’ duties also failed. There was no material breach to induce; Clearwell had no proprietary interest in the name as pleaded; and the directors acted honestly in addressing genuine safety concerns and assisting with contractually contemplated improvements. The directors’ duties involved a subjective assessment of their good-faith view of Clearwell’s interests.
7. The abuse of process defence was rejected. Although some factual overlap existed with earlier fee proceedings, the current claims involved different parties and substantial issues which could not realistically have been litigated there.
8. The counterclaim was dismissed in its entirety. Hydropath and Clearwell were not entitled to a declaration that the products were properly ATEX certified or ETL listed.
