Aspect Land & Hydrographic Surveys

Aspect Land & Hydrographic Surveys have forged an alliance with several accredited diving contractors throughout the UK to offer a full range of marine archaeology, diver support and salvage services.

These divers represent some of the most experienced in the country and have developed a reputation for performing the most difficult of underwater tasks safely, efficiently and in a timely & cost effective manner.

Complex survey and salvage operations have been accomplished at open water locations in water depths of up to 40 metres, with safety and professionalism paramount in all operations.

Our continual assessment of these companies ensures that they maintain and upgrade their equipment to the highest standards, complete relevant training and remain updated on the latest diving techniques and methods.

Aware of the environmental issues faced by our clients, all dive contractors work to strict protocols and current regulations, maintaining an excellent relationship with various regulatory authorities.

-Our diver inspection services include;

Underwater Video & Photography - digital stills, diver led underwater videos or tripod mounted remote videos, with full narration, of seabeds, pipeline routes, outfall location & condition surveys in rivers, weirs and lochs.	jj	Pipeline Deployment & Inspection - assistance in all positioning and engineering aspects of new lay pipeline deployment operations and conduct condition & inspection surveys of existing outfalls and diffusers.

Marine Salvage & Object Recovery - detection and removal of seabed objects and debris from shipping channels, ferry approach routes and ports and harbours that may cause damage to marine vessels.		Instrumentation Deployment & Recovery - deployment to fix seabed mounting, recovery and analysis of tidal data recorded over a pre-determined period to investigate the variability of current trends.

Marine Archaeology - report of human interaction within the marine environment by studying sunken vessels, shore side facilities, cargoes & submerged landscapes.		Accident Investigation & Salvage Assessment - assistance to Marine Accident Investigation Branch (MAIB) in determining the circumstances and causes of marine accidents in UK waters.

Piers & Dock Wall Inspection Survey - accurate harbour and dock wall inspections for damaged block work, structural defects or measurement and assessment of debris build-up.		Geophysical Works - sub-strata ground truthing using jet probes & air lances for verification of geophysical data sets and collection of seabed sedimentation for investigation of seabed properties.

We offer a coordinated, cost effective underwater service in support of our marine operations, ensuring time on-site is used effectively and efficiently.

All our approved diving contractors are equipped with full surface demand facilities, and operate with both bio-security and client confidentiality to the fore at all times.

Our experience is derived from a wide range of civil engineering, construction and environmental projects including video seabed surveys, mooring inspection works, pipeline deployment works, archaeological surveys, geophysical works, ground truthing, seabed sampling and marine salvage.

Our survey vessels offer an ideal dive platform, thus negating additional costs associated with the mobilisation of diver support vessels with the added benefit of RTK GPS positioning available to the dive team, ensuring they are sited over the exact location prior to descent.
