Conceptual Design and Engineering (projects)

Clients seeking preliminary or conceptual designs can depend on the full participation of the P&S consultants at the earliest stages of their project. Based on the experience of our experts a quick but thorough scan will be made of the project, indicating the key elements that are required for such an early stage design.

Conceptual Design and Engineering (equipment)

Equipment for dredging and marine works is much more than a tool to fix a job. It is the result of decades  of technological development in pump and cutter-head design technology, drives, winches. The development of this hardware has always been tailored towards improvements in performance and output of the equipment, whilst keeping costs low and possibly reduce unit rates.

Construction Methods and Planning

A detailed assessment of the construction methods and planning is crucial as a basis for cost estimates and realistic project duration.  Suitable equipment is proposed based on the scope of work and the project-specific conditions and constraints, with associated working methods and estimates for production and costs. The project budget and duration is then based on both this estimate and an evaluation of project-specific risks. In the tender phase, these estimates can serve as benchmarks for contractor proposals.

Cost Estimates and Risk Assessment

The analyses of P&S consultants are aimed to identify the internal and external risks and opportunities of the project. This includes technical, contractual, economic and  environmental & mitigation aspects, including specific stakeholder concerns. In consultation with the client, we can prepare a project specific risk register to support the determination of a contingency allowance for the project CAPEX, OPEX and Business Case.

Dredge Project Preparation

During the initial development stages of marine infrastructure and dredging projects, the technical and economical feasibility is assessed. At the same time that these studies are being done initial preparations for the realization phase of the project are made in case the green light is made.

Site investigation campaigns, scope determination, and packaging of works, cost and risk assessments, drafting of contract conditions and employer’s requirements. 

Marine Works

Marine works projects like breakwaters or revetments, and the installation of pipeline protection,  are often designed based on extreme load conditions and failure probabilities.  

Dredging and Reclamation

P&S experts have worldwide practical experience in dredging and reclamation projects. This diversified experience ranges from conceptual design to risk management and from cost estimates to expert opinions.

Our clients vary from port authorities and governmental organizations to private investors and contractors. We provide our services tailored to the specific needs of each client, relying on a personal, hands-on approach which is highly valued in the dredging industry. Clients can expect from us that the interdependencies of technical, financial and contractual aspects will be given due care and attention to achieve “best for project”  results.

Hydrographic Surveys

Dredging and marine works are virtually impossible without proper hydrographic surveying. Clients need to give due care and attention to several questions with significant implications, like:

Maintenance Dredging

Maintenance dredging is a permanent operational cost burden in many ports.  With a critical evaluation of the maintenance dredging scope and philosophy, P&S can identify possibilities for significant savings and an effective implementation strategy for your maintenance program.

Contracts and Conditions

 Sound contract specifications and conditions are paramount in order to define a clear scope of the Works, offer Contractors the possibility to offer their best price, and realize the project on the bases of a professional Employer-Contractor relation. It helps trouble free execution of the works if no unforeseen conditions appear, and helps solving discussions and disputes in case such unforeseen contract conditions do appear.

Procurement Strategy

Procurement of dredging and marine works is a puzzle not easily solved by many clients who face such a task. The overwhelming number of options for types of contract, remuneration, packaging of the works, prequalification, as well as evaluation criteria, make it difficult to choose which way to go. P&S has the experience to provide practical guidance on the matters.

Dredging Environmental Effects and Impacts

In many dredging projects, environmental effects and impacts are high on the priority list of our clients. Especially when dealing with specific geomorphologic conditions or dredging and building in ecologically sensitive areas, the environment must be considered carefully, during design and during the construction of maritime projects.

P&S has provided various assessments and advice on environmental effects and impacts, including:

Project Management Assistance

Planing, design, prepare, procure, and realize marine works projects involve many parties over an extensive period of time.

Based on a thorough understanding of marine works, challenging site conditions, execution options and practices, and the contractual relation of the employer and the contractor, P&S is capable to advise the client in a realistic and pragmatic way throughout the subsequent phases of the project.
