About IMWO
IMWO works to advance the planning, delivery and long-term performance of marine and hydraulic works worldwide. We develop engineering knowledge, compare project experience and publish practical research for the people and organizations responsible for ports, waterways, coasts and water infrastructure.
Technical guides connect engineering principles with documented project conditions: dredgeability, survey and acceptance, intake and outfall performance, contract mechanisms and delivery interfaces.
Explore engineering knowledgeCross-project studies examine how scope, procurement, responsibilities and operating conditions affect delivery. Published reports bring case evidence and analytical findings together in web, PDF and data editions.
Read the dredging contracts reportDated project histories follow scope revisions, procurement, approvals and delivery milestones. Structured records and open exports make the engineering package, responsibilities and outstanding questions available for further analysis.
Use the public datasetsProfessional scope
Coverage follows identifiable engineering packages: navigation and berthing, coastal protection, river and flood works, reservoir maintenance, and water-system interfaces. Wider development programmes are assessed through their relevant work packages.
Navigation access, breakwaters, quay walls, berths, terminals, marine yards, ferry facilities, fishing harbours, and port-side utility interfaces.
Capital and maintenance dredging, reclamation, sediment placement, beneficial use, inland navigation, channel condition, and disposal constraints.
Shore protection, revetments, seawalls, nourishment, flood and erosion works, waterfront adaptation, and coastal access structures.
Flood alleviation, river works, reservoirs, dams, weirs and canals, together with intakes, outfalls, marine pipelines and related temporary works.
Enterprise services
Our project intelligence helps contractors and engineering consultants screen relevant work, compare published conditions and prepare their next technical or procurement review. The reservoir-maintenance comparison examines supplier entry, repair scope and work allocation at Portsmouth Water and Welsh Water. Project histories and reusable shortlists support continuing review as the work develops.
Public guides, published research and open datasets form the shared knowledge base. The enterprise service programme focuses on tailored project monitoring and continuing analysis; subscription access and commercial terms are under development.

IMWO reconciles procurement notices, amendments, owner releases and published technical records, then explains their implications for the work package. Each assessment retains its sources, dates and outstanding questions. Full-document access and the extent of review are stated where they affect participation or preparation.
Tender and award notices, contract registers, authority releases, procurement plans, and public project records.
Environmental filings, permits, lender documents, planning decisions, concession records, and development approvals.
Attributed owner, operator, consultant, contractor, supplier, investor, and financing disclosures tied to identifiable marine scope.
Dated trade, financial, local, and specialist reporting used with clear attribution and checked against available primary records.
Send a documented project lesson, a technical article proposal or a question for comparative research. Useful contributions identify the engineering problem, project conditions, supporting evidence and limits of application. Corrections and additional primary records help improve the published work.
The methodology explains our research approach. Governance covers independence, conflicts and corrections; People identifies published roles and accountability.
