We are proud to announce that starting august 2017 Laurens Poelhekke will be posted in Hanoi, Vietnam for CDR International through the Young Expert Programme (YEP) and in cooperation with VINWATER.

The YEP-programme ( is jointly funded through the Dutch Ministry of Foreign Affairs and the Netherlands Water Partnership (NWP, ) and gives young experts the opportunity to gain experience abroad. The young experts are supported by the programme through an intensive three week training course and coaching for two years. This year the YEP-group consisted of 30 young experts from over 13 different countries. Whom together followed the three week training course focussing on personal development (through MBTI), intercultural communication, facilitation, conflict management & mediation, negation and masterclasses on the themes of water, food and the development of business cases.

Laurens Poelhekke will work closely together & share office space with VINWATER ( in Hanoi. VINWATER is the Vietnam Netherlands Center for Water and Environment. Founded as the result of a long-standing relationship between Vietnam and The Netherlands, particularly the strong partnership between the Vietnam Water Resource University and the Delft University of Technology. VINWATER is a science and technology organization that aims to further facilitate the cooperation between the two countries in the Water Sector.

In posting Laurens in Hanoi, CDR is expanding its international ambitions in doing business in South East Asia. CDR aims to collaborate with national partners on the topics of Inland Waterway Transport, Port Development, Coastal Erosion, Flood Protection, Coastline Development and Protection, Inland Water Resource Management (IWRM) but also on the nexus of water and agrofood.

CDR wishes Laurens Poelhekke the best of luck with his posting in Hanoi, Vietnam!

Laurens-Poelhekke Photo SQR 20160623CDR has increased its engineering capacity and welcomes Mr. Laurens Poelhekke who joins as a Civil and Marine Project Engineer.
Laurens graduated in 2015 at the Delft University of Technology. Thereafter he continued with further research on his graduation topic at the renowned Deltares institute, which led to the paper “Predicting Coastal Hazards for Sandy Coasts with a Bayesian Network”, which is currently under review at the Journal of Coastal Engineering. The research involves predicting coastal erosion and overwash using a combined probabilistic approach with the numerical model XBeach. The research has been done for the Deltares RISC-KIT project and is currently being used in the development of an Early Warning System for marine coastal hazards for several European countries.
Laurens has a wide international and engineering interest which he has shown during his education, by undertaking several projects and internships abroad, spending several months in Romania, Portugal and Cuba.
CDR wishes Laurens all the best at the start of his career.

CPC Presentation by Steven te Slaa 20151212_160605 MNP

Presentation “Design Process of a Sandy Convex Shaped Beach”

By | All, Asia, Uncategorized | No Comments

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.

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

By | Africa, All, Uncategorized | No Comments

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 | No Comments

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.
