Article Hydro International - photo 2.jpgArticle Hydro International - photo 1 Raw Data as Information Source – Model for Remediation Design Study of Southeast Asian Port Basin.
Authors: Bas van de Sande (CDR International), Eelco Bijl (CDR International), Jelle Tamminga (DEEP).

CDR International in cooperation with DEEP have written an article on the extensive site survey as performed for the remediation design study of a Port Basin in South-east asia. This site survey included a detailed bathymetric survey using a double multibeam system and a drone survey. As very high detail was required for the whole facing for proper analysis, the raw measured data was used as 3D model without any further post-processing as this may lead to loss of data.

NNPC Study Tour in the Netherlands and Belgium

By | Africa, All, Europe

From February 15th-20th, 2016 a group of engineers from NNPC (Nigerian National Petroleum Corporation) visited the Netherlands and Belgium for a study tour related to the development of GRIP (Gas Revolution Industrial Park) at Ogidigben, Delta State, Nigeria.
During the study tour Dutch and Belgian sites were visited related to land reclamation, coastal and polder protection, dredging, port construction and exploitation, petrochemical and gas industry, inland waterways, and geotextile engineering.
The NNPC study tour participants were eager to learn about the Dutch land reclamation, water management, port management and related industries, in view of their upcoming GRIP Development.

Presentation “Design Process of a Sandy Convex Shaped Beach”

By | All, Asia, Uncategorized

Paper “Design process of a sandy convex shaped beach layout” was presented at the 6th International Conference on Structural Engineering and Construction Management.
As part of the Value Engineering project for Colombo Port City, a delegation of CDR International presented the paper ‘Design process of a sandy convex shaped beach layout’ at the 6th International Conference on Structural Engineering and Construction Management in Kandy, Sri Lanka.
The technical content of the conference has been diversified with respect to earlier editions, now including Water Safety and Hydraulic Structures. The paper, which presents a case study of the Colombo Port City development, was well received by the audience who appreciated the insight into the CPC related engineering works.
CDR likes to thank CHEC for providing the opportunity to present the paper on their behalf. Moreover, CDR likes to congratulate the organizing committee for successfully hosting the event.

An extensive 2D Physical model test has been performed at INHA in Spain for the remediation design study of the Port Basin revetment in South-east Asia.
During a model testing campaign of 5 weeks the actual cause of the displacements and possible remediation solutions for different areas have been investigated and optimized. A highly flexible approach was adopted as the optimum remediation design should be derived based on progressive insight and knowledge of the functioning of remediation design options. The model testing provided highly interesting information on the local circumstances, impact of construction aspects and verified a stable and very cost-efficient design.
The actual situation and construction as in reality was tested first, providing similar results as could be seen during the site visit. This proved sufficient reliability of the model testing and different remediation designs were tested and further optimized. This resulted in different remediation designs in the Port Basin area.

CDR International welcomes Mrs. Flavia Bonfantini

By | All, Europe, Uncategorized

Flavia Bontfantini 20151118CDR International has increased its engineering capacity by employing a new staff member. As from November 1st 2015, Mrs. Flavia Bonfantini (MSc.) is full-time participating the CDR International team, and works as project engineer on international projects.
Mrs. Flavia Bonfantini is a cum-laude graduated civil engineer educated by renowned professors in Italy and in Delft, The Netherlands with UNESCO-IHE. Through several academic projects she has developed a wide knowledge of several different aspects of civil engineering. She has designed marine structures, breakwaters and systems for water supply and sewage treatment. She has researched and prepared her MSc. thesis on rubble mound breakwaters for the development of a new single layer concrete armour unit.
We are very proud that Mrs. Bonfantini is strengthening our team and wish her all the best in her promising career.

Gas Revolution Industrial Park, Delta State, Nigeria Ready to Proceed to a Next Phase

By | Africa, All, Uncategorized

By finalizing the post concept masterplan strategic studies for the Nigerian National Petroleum Company (NNPC), the Gas Revolution Industrial Park (GRIP) project is ready to proceed to a next phase.
The results of the CDR strategic studies provide the technical background required to support short term discussion making. The provided solutions to tackle the identified technical constraints enable the accelerated development of GRIP. This is further supported by an in-depth land reclamation plan which connects to the mid and long term port masterplanning.

Investigation and Design Study of Revetment Remediation Works

By | All, Asia Pacific, Uncategorized

Inspection Revetment IMG20151002NCDR International BV has been involved in the investigation and remediation design study of a Port Basin revetment in South-east Asia. After construction of revetment works some initial, unexpected settlements of the armour layer occurred which may endanger the stability of the revetment over time.
A site visit was performed including high detailed survey of the facing above and below water by drone and bathymetric survey. The bathymetric survey was done by a dual Multibeam system, providing high detail data and highly accurate image of the armour facing below water level.
Based on the investigation study, including review of design, construction and supervision, a physical modelling study is performed to obtain the most practical, reliable and cost-efficient remediation design. Attention is paid on the execution aspect of the design to minimize further negative effects.
