TAG’s record runs from the redevelopment of a mothballed shipyard for the Channel Tunnel TBM build through to the largest maritime construction contract awarded on Teesside in twenty-five years. Few sponsors in the UK heavy fabrication sector can point to a comparable record on contracts of scale, cross-border procurement and finance, or on standing up new industrial facilities.
In 2006, TAG won the contract for the topside modules of the SeaDragon Offshore Oban B deep-water semi-submersible drilling rig. The hull was procured from the Sevmash shipyard in Russia, with topside design by Moss Maritime. The 15,000-tonne topside modules were fabricated at Haverton Hill on Teesside, and the rig was delivered to PEMEX in 2010.
To make the project bankable, TAG was instrumental in arranging a $1.2bn line of credit with Lloyds Bank and a five-year, $958m charter contract with Pemex Exploration & Production. The vehicles operating that project (SDO and PSL) generated trading accounts covering the procurement, design and construction of two semi-submersible drilling rigs of more than 30,000 tonnes each.
The project began with the redevelopment of the dilapidated Haverton Hill shipyard to undertake the build. Both Tunnel Boring Machines, weighing 2,500 tonnes each, were assembled, commissioned and installed at Stratford Box in London — on time and to specification.
The TBM commission was the foundational TAG-led programme: a heavy industrial site brought back into productive use, a global engineering client delivered to, and a workforce that went on to deliver everything that followed.
Following the SeaDragon programme, TAG commissioned and constructed an automated tubular production facility on Teesside at a capital cost of £26m. The facility was designed for the rolling and welding of large-diameter tubulars, and used for the construction of monopiles, tripods, jackets and transition pieces.
It supplied EON’s Humber Gateway project and Saipem’s Elgin piles, among others. The facility remains a reference point for what can be built in the Teesside cluster when capital is matched with operational expertise.
TAG was the first UK manufacturer to secure a substantial monopile and transition piece contract for a wind farm in British waters. The scope covered 16 monopiles and transition pieces for the Humber Gateway development, eight kilometres off the Yorkshire coast, with each monopile weighing 650 tonnes.
The first batch of four 60-metre monopiles and four transition pieces was loaded out from the River Tees facility, the monopiles driven onto the barge by self-propelled modular transporter and the transition pieces lifted aboard by crane at the wet dock. Humber Gateway is a 73-turbine array generating up to 219MW, enough to power around 170,000 homes.

Senior members of the TAG team have, over their careers, been associated with a substantial portfolio of UK and international offshore and infrastructure projects. The summary below is illustrative.
