Where we work
Upstream
ABL Group companies ABL, AGR and Longitude, provide a wide range of expert engineering and consulting services to support upstream assets throughout their lifecycle – from reserves and resources evaluation, early feasibility and engineering, drilling, field development and construction, transportation and installation, operations and maintenance, product optimisation and life extension, through to decommissioning.
Together, we are a leading technical authority in rigs, wells and subsurface.
Midstream
ABL Group’s oil & gas specialists have been at the forefront of offshore midstream development for over 40 years. Our teams of marine and engineering consultants include specialists in subsea pipeline engineering, SURF and floating storage solutions technology, with project experience covering some of the world’s most high-profile and complex offshore oil and gas storage and transmission projects.
Downstream
In recent years, large construction projects have been executed with worldwide procurement strategies requiring significant marine transportation campaigns to bring high-value items from their place of fabrication/supply to the final site location. ABL Group offers a broad range of specialised capabilities to support the secure, optimised and sustainable development of onshore projects from initial concept right through to operations and decommissioning.
