Early works for LNG plant, Brass Island

The Brass LNG Project’s objective is to construct a LNG Complex on Brass Island, Bayelsa State, Nigeria, and in so doing, develop Nigeria’s abundant gas resources, reduce the adverse effect of gas flaring on the environment, and provide social-economic benefits to the local and wider Nigerian communities. The LNG complex will be designed to produce approximately 10 million tons per annum (MTPA) of LNG, as well as LPG and Residual NGL products.

The early works

In October 2007 Brass LNG awarded Nigerian Westminster Dredging & Marine Limited (NWDM) the Early Works EPC Contract. The project consisted of the construction of a Pioneer Camp and three Pre-Loads to provide early settlement for the future tank farm of the proposed Brass LNG plant. In more detail the Scope of Work consisted of bush clearing and topsoil removal, the construction of temporary roads and pipeline crossings, the excavation of sand for the construction of the pre-loads, installation of vertical drains, the installation of settlement monitoring instrumentation and the monitoring thereof and covering the completed pre-loads with poly sheets.
The Pioneer Camp was designed to be fully self-supporting. Apart from accommodation units it consists of offices, catering, laundry and water treatment facilities. For the power supply three generators were supplied and installed. Furthermore, provisions were made for waste water and sewage treatment and for waste disposal an incinerator was supplied and installed. 

Execution

The bush clearing was mainly sub-contracted to local contractors from the three host communities. Immediately upon having the first areas cleared, sand excavation started to construct the temporary roads, and to create dry and stable platforms for the construction of the accommodation and offices, and for the pre-loads.
Approximately 1,5 million m3 of sand was excavated and transported for the construction of the three pre-loads, which were elevated to  approximately 20 meter height. The required sand was excavated from an onshore borrow area. Over 30 heavy duty dry earth moving machines were brought to site to execute the works, such as excavators, bulldozers, vibro roller compactors, articulated dump trucks, etc.

Construction of
Marker Wadden

Boskalis has been awarded the first phase of the Marker Wadden development in the Netherlands. The project includes the construction of an island with underwater landscaping. The Marker Wadden are natural islands that will be developed in the Markermeer lake in the years to come. They will provide a major boost for the ecological quality of the Markermeer lake. The natural shores of the islands will give fish more opportunities to spawn and feed. As a result, large numbers of birds such as terns and waders will return to the area because there will be more food for them. The construction of the Marker Wadden will transform the map of the Netherlands.

Outer harbor channel widening, Adelaide.

The Port of Adelaide is the primary port in South Australia, located at Outer Harbor. The port is operated by Flinders Ports Pty Ltd (Flinders Ports) and handles both container and cruise vessels, contributing significantly to the State’s economic activity. Flinders Ports identified the need for an upgrade of the existing infrastructure driven by the emergence of Post Panamax class vessels. To meet this growth the existing channel had to be widened to accommodate vessels with a maximum width of 49 m without operational restrictions. Flinders Ports contracted Boskalis to execute the dredging works.
