At Thomson we are able to support our clients with environmental issues associated with port and harbour expansions, reclamation, capital and maintenance dredging activities, and aggregate extraction. We are highly experienced with dredging and disposal operations for maintenance and capital dredge projects, using water injection dredging as well as the more traditional methods such as grab and back-hoe.
Our marine consultants provide specialist support and quality reports for all stages of port and harbour developments, including licence application, sediment quality, disposal options, survey design and licence conditions/monitoring requirements. We regularly carry out Water Framework Directive and impact assessments for projects such as new jetties, breakwaters, and piers. We also help our clients with INNS (Invasive Non-Native Species) and protected species assessments in their ports and we can advise on the disposal of dredge spoil, including beneficial use schemes and the impact of disposal at licensed disposal sites.
Many of our clients appreciate the value of receiving a combined service from one supplier; Thomson can cover all environmental issues associated with development projects, from subtidal to intertidal, to onshore considerations. We take care of all stages from desk-based design, to planning and delivery of marine licence compliance. This includes development and implementation of management and monitoring plans, conducting surveys and laboratory analyses of the samples we collect. Sample analysis may include faunal identification, Particle Size Analysis, or chemical analyses to test if sediments trigger Cefas action levels for contaminants.
