ABOUT US

HIGHLY EXPERIENCED

D360 was established in 2023 by Mark Hill MIDE AaPS, who brings more than 30 years of experience in the global high hazard industry. 

Throughout his career, Mark has worked with some of the largest and most recognised organisations across the oil and gas, chemicals, energy, and industrial sectors.

His work has taken him across the UK, Europe, and the USA, supporting complex and high-risk projects and consistently delivering them on time and within budget, with safety at the forefront of every operation. This experience led to the creation of D360, with the aim of supporting clients in a more effective and collaborative way.

CORE VALUES

Since then, the business has evolved and grown significantly, particularly in 2025, and D360 is now a team of 12 dedicated professionals and supported by a number of contract partners. Despite this growth, the company continues to be guided by its core values.

Taking the unknown to the known
Finding practical solutions for our clients
Ensuring safety remains central to everything
