About us

Pioneers in safety.

StS has been in the forefront for increased HSE focus and for establishing guidelines for best practice when it comes to hot work in habitats.

A notable milestone in this work was our contribution to the SfS (Samarbeid for Sikkerhet – an advisory organ consisting of the petroleum safety authority, oil companies, oil service companies, unions and other relevant industry parties), which resulted in one standard checklist for Habitat work in Norway.

This ensured that the high HSE levels that StS strive to implement and achieve became the standard practice for all habitat companies.
