The Gardline Group is a holding company based in Great Yarmouth, England. The group consists of more than 35 companies focussed primarily on service industries. The holding company was established in 2009 to bring together a number of existing companies including the original Gardline Shipping, first established in 1969 which continues today, focussed on shipping and other maritime services.


Gardline Shipping was first established in 1969 to provide marine support to offshore oil and gas industry in the North Sea. In 2009, as part of 40th anniversary celebrations, the Gardline Group was established to bring together a large number of multi-disciplinary companies involved in a range of activities that include satellite communications, marine sciences, security, ship building, dry dock engineering, geographical information systems, digital mapping and vessel charters.

The group currently employs around 1,000 personnel worldwide and has a turnover of approximately £140 million (GBP).[1] Gardline is now the largest employer in the Great Yarmouth area.[2] The company continues to sponsor careers fairs in the region.[3]

In 2011, the Gardline Group was ranked the 20th largest in the Norfolk region by the Eastern Daily Press, accounting firm PricewaterhouseCoopers (UK) and law firm Mills & Reeve.[4]

Offshore wind farms[edit]

In recent years, Gardline and its subsidiary companies have expanded their services to include support of offshore wind farms as a core service. The company's offshore wind farm related businesses have experienced significant growth in line with the UK Government's wind farm development programs.[5]

In 2010, Gardline Environmental, a subsidiary of Gardline Marine Services, won a tender to provide environmental survey services for the proposed Dogger Bank offshore wind farm.[6] Later that year, the company announced it had been awarded environmental survey work for the proposed Atlantic Array offshore wind farm project.[7]

In 2012, Gardline announced it had entered a bid to provide port operations services to ScottishPower Renewables and Vattenfall AB, one of the successful consortia in Round 3 of the UK Government's offshore wind farm program.[8] In 2013, another Gardline subsidiary, Alicat Workboats, announced the construction of 4 high-speed catamarans to service the Robin Rigg Wind Farm.[9]
