Handling and transportation of petroleum products and chemicals always require special attention and highest skills. This is why we have always been focussing on quality, health, safety and the environment (QHSE) at Harren Tankers. These four factors are constantly developing and need permanent evaluation and adjustment. In response, Harren Tankers has implemented ISO 9001:2015 in its organisation. This certification contains policies and guidelines that will keep us focused on these factors and further improve our safety standards.
