How we work

We work around the globe in all major hazard locations, from deep sea to desert, operating in many cultures and languages. Our scope extends across a wide range of facilities on and offshore, from those with large workforce’s to those which are normally unmanned. 

This is how we work: 

Outcome focused - we don’t offer you lists of products. Instead, we ask ourselves what will make you safer. Consequently, we’ll only ever provide solutions we think will complement and enhance your business. 

Consultancy-led – before we start any work, we need to understand the problems and issues our customers are facing. A detailed situation analysis enables us to offer sharp, effective and tailored solutions to achieve your goals. 

We provide what is required to make you safer – we don’t hesitate to try new approaches as we firmly believe that every customer is different. If we need to involve experts from other industries, organise training in various locations and manage the logistical issues, it’s all within our scope. 

Our customers

We believe that every customer is different, and that is why we come up with efficient solutions to make your workforce safer.  We believe in effecting change at your pace. Our team will walk you through the entire process, providing full support and working on changing internal perceptions. 

We make sure that every step of the process is clear and transparent. This mutual trust is what creates strong and long-lasting relationships with our customers.
