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.

Coastal protection, St. Petersburg

St. Petersburg is a UNESCO World Heritage City, but its location along the River Neva means that it has been threatened by over 300 floods since its founding by Peter the Great in 1703. The completion of the new 25 km long storm-surge barrier across the Gulf of Finland ensures that the city will no longer be vulnerable to high tides and devastating floods. As a result of the new Flood Protection Barrier, however, the old winding access channel had to be replaced with a new, straighter, more easily navigable channel.

Cleanup, Zellingwijk area

The Zellingwijk quarter of the village of Gouderak was built in the middle of the last century. In the early 1980s it became clear that the soil underneath this residential area was heavily contaminated as a result of the dumping of waste - mainly mineral oils and pesticides. The homes built on the site were subsequently demolished in the mid-1980s. Pending definitive remediation work, a layer of concrete / asphalt was applied to seal the site.

The archipelago consists of some 30 islands with a total of 160 km of shoreline and has a population of 800,000. Whereas the surface of Bahrain in the year 1960 was around 650 km2, the last decennia have seen a steady increase in the surface till a respectable figure of 740 km2 in 2007. This increase has been achieved by a various number of small and mayor reclamation projects.

Port expansion, Gijón

The Spanish port of Gijón on the Bay of Biscay processes more than 12 million tonnes of bulk goods annually. With the expansion of global trade and increasing ship sizes, the terminal was lacking capacity to handle the traffic. The maximum draft for the ships of 18 meters is another obstacle to the development of the port. So the Port Authority of Gijón developed a plan for additional modern facilities in an area measuring 145 hectares to the north of the existing port. This includes a bulk terminal with a transfer capacity of more than 25 million tons and a storage area measuring 60 hectares for a maximum of 2 million tons of coal and iron ore a year.
