With a background as a DP Company Authority and Accredited Vessel Surveyor, he ensures every GreenHulls solution is grounded in regulatory compliance and on-deck practicality.
"I founded GreenHulls to turn technical complexity into operational clarity. Our mission is to provide solutions born from the practicalities of working at sea, ensuring innovation never comes at the expense of safety or compliance."
Who We Are
Our approach
GreenHulls was established as a strategic response to a persistent industry disconnect: the gap between high-level corporate strategy and the practicalities of the deck. Having served in senior roles for global operators, Andrew recognised that technical complexity, processes and siloed operations often hinder operational efficiency and ultimately safety.
GreenHulls channels this deep operational background into a smarter, more scalable business model. By combining trusted consultancy with technology-enabled solutions, we help operators solve complex challenges without compromising on safety, compliance, or commercial return.
