SMD is one of the world’s leading manufacturers of remote intervention equipment, working in hazardous environments worldwide. Customers span a range of sectors from energy (oil and gas, marine renewables and offshore wind infrastructure), to telecoms, mining, naval / military and scientific communities. The company has recently reorganised itself along a number of key business streams: Work Class Remotely Operated Vehicles (ROVs), Subsea Trenching, Marine Renewables, and Submerged Mining. SMD has 90,000 square feet of manufacturing space over 4 production sites in and around Wallsend near Newcastle, where the head office is based. The company also has offices in, Singapore, the US and Brazil, and employs over 300 staff.


SMD’s origins are in agricultural engineering related to research at Newcastle University. In the early 1970’s, the North Sea oil industry required the development of seabed geotechnical knowledge, together with theoretical analysis of the particular problems encountered in seafloor earth moving activities.

SMD began to design and manufacture sea floor trenching and ploughing equipment used to lay and bury oil and gas pipelines. SMD’s technology was unique in its application of land based soil mechanics principles to innovative subsea trenching machines, and a number of benchmark patents resulted from this early work. The innovation of a new range of more powerful and more capable trenching machines is helping the Offshore Wind industry meet the technical challenges identified in the early Round 1 Wind Farm Installations in UK waters.

SMD’s innovations in product, technology, and offering to market have seen the company grow from shipping its first WROV in 2005, to having the largest market share of the three major independent WROV manufacturers in 2010 (based on overall market size forecasts by the Douglas Westwood analyst group).

SMD bring over 40 years of subsea engineering experience to various markets and are currently in the process of building the world’s first deep sea mining vehicles for Nautilus Minerals. SMD’s Renewables business stream is dedicated to developing cost effective installation technology for marine renewable energy.
