Libyan Port and Maritime Transport Authority

Year:

2007 – 2009

Description:

Royal Haskoning and Maward Consulting Engineers performed a site investigation and design study on the maintenance and development of the existing port of Zuwara. The present port consists of a rubble mound breakwater constructed in 1937 and a jetty built some 40 years ago. The new design includes the rehabilitation of the breakwater, a new 450 m long quay wall with an on dock container yard, port buildings, dredging/reclamation and navigational aids. Based on the developed design dedicated D&C tenders documents were produced.

Harawa and Bin Jawad, Libya

Year:

2006

Description:

A full study and design for two ports planned at Harawa about 60 km east of Sirt and Bin Jawad about 150 km east of Sirt are being conducted. The design includes sea side and land side facilities. A full wave climate study and wave propagation model is conducted and further sediment and morphology study is included.

Year:

2004 – 2007

Description:

Royal Haskoning was commissioned to carry out day to day supervision of the breakwater repairs at Ras Lanuf Harbour, including professional under water inspection services. Since the construction of the port in 1980, the primary armour units at the sea side slope of the main breakwaters had suffered from accumulated damage. All broken or fractured Tetrapods (up to 48 Tonnes) have been carefully removed and were replaced by new ones. During the same period also detailed under water inspections of berths 3A and 3B of the caisson type were carried and subsequently full specifications for future concrete repair works were developed.

2003 – 2006

Description:

On the Mediterranean coast about twenty kilometres west of Tripoli, Libya, the Al Maya fishing port was developed. The port consists of two interconnected land excavated basins to shelter small and medium sized fishing boats. A 120m long rubble mound breakwater was considered to protect the port entrance and the approach channel from waves.

Royal Haskoning executed a study to optimize the port design, by means of comprehensive numerical and physical modelling. Numerical modelling included wave propagation to determine extreme wave conditions in front of the breakwater, and wave penetration to determine downtime of the port. Also water circulation within the port basin was numerically assessed, indicating the refresh rates. A physical 3-D scale model was set-up to investigate the breakwater stability and to verify the wave penetration calculations.

Following design and studies, daily construction supervision of all works was executed.

Tripoli, Libya

Client:

Libyan Port and Maritime Transport Authority

Year:

1997 – ongoing

Description:

Tripoli harbour, one of the major ports of Libya, is protected by a main breakwater of 4.7 km length. This breakwater, running parallel to the coast and situated in water depths up to 12 m, was hit by two severe storms in 1981. They inflicted extensive damage over approximately half of its length, both to the parapet walls and to the primary armour layer (Tetrapods).

The re-design, prepared by consultant in the period 1981 – 1984 was not implemented for various reasons. Faced by increasing threat to the harbour, LMPA asked in 1997 to reconsider the 1982 redesign.

The project started with a detailed survey of the present breakwater and seabed situation, together with an update of the design (wave) data. After developing several possible design modifications it was chosen to adopt a new Accropode primary armour layer in combination with an extended under water berm at the seaside. Along the first stage of the breakwater where a landfill is present a stone filled canal was designed at the harbour side in order to tackle the venting and overtopping problem. The chosen design modification was finally optimised using small scale physical model tests, which resulted in the final design. The project was concluded with the revision of the 1982 tender documents, including tender drawings, specifications, bill of quantities and cost estimate.

Client:

Government of Libya

Year:

1982 – 1988

Description:

The company was commissioned to design two new naval bases for the Libyan government. These bases were also to serve as civilian ports. For security reasons these bases were to be located remote from centres of population and hence they had to be on previously unused sites. The projects included the full provision of marine and land based services, dredged channels, quays, accommodation, industrial areas and office complexes. The cost effective solution for one site was for an offshore harbour whereas for the other a harbour basin was formed by dredging inshore of the coastline.

Client:

Government of Libya

Year:

1982 – 1988

Description:

The company was responsible for master planning, investigations, breakwater model studies, tender documentation, design and project management for this billion dollar naval base. The project comprised 3.5km of breakwaters, 6km of berth, shiplift and repair facilities, 16,000 square metres of workshops, 13.7km of highways and housing and communal facilities for 2,700 naval personnel. The company designed all the maritime and reclamation works. For each section of the works detailed design briefs were prepared and the company then co-ordinated and reviewed the designs, drawings and information produced by almost 20 other consultants, architects, contractors and testing laboratories.
