Beach replenishment, Newbiggin Bay

Newbiggin by the Sea was once a seaside resort, with the residential area focused around the bay. The beach has severely eroded over the years. If the coastline would continue to recede, sea walls could begin to collapse, imperilling coastline properties. The falling beach levels and increased risk of seawall failure led to a strategy and proposal to import beach fill, along with construction of an offshore breakwater to retain material. Boskalis expanded the existing beach and protected it from erosion.

The project involved:

  • Replenishing the beach with 500,000 tonnes of new sand;
  • Building a 200-meter breakwater in the bay to ensure new sand is not eroded;
  • Enhancing the beach promenade to make the area more attractive to visitors and to allow them a good view of ‘The Couple’.

Creating two berths pockets, NCIG terminal

For 200 years the Port of Newcastle has been Australia’s premier coal export harbor. Of the 95 Mtpa of various commodities such as steel, aluminum, minerals and so forth exported from Newcastle in 2008-2009, 90.5 Mtpa were attributable to coal. Average annual growth rate of coal exports from 1990 to 2006 was 6.1%. This constant increase has caused a spike in ships queuing to enter the harbour to be loaded. To increase capacity and avoid these traffic jams, a decision was made to develop a new coal stockpile area and construct a third coal terminal.

Port expansion, Balboa

The plans to expand the Panama Canal represent one of the most important infrastructure improvements of the 21st century. Since its opening in 1913 the Canal has provided the shortest and most economically viable shipping route from Pacific to Atlantic seaports. With the ever-increasing size of modern-day vessels, it was inevitable that the Canal would need to be widened and deepened. The expansion of the Canal has made the extension of the Port of Balboa at the mouth of the canal on the Pacific Ocean a necessity. The Phase 4 projects included Marine Works and Civil Works to improve two existing berths and to build a completely new berth capable of handling not only Post Panamax but also Super Post Panamax ships.

Port environmental mitigation measures, Hamina

Hamina, which is close to the Russian border in south-east Finland, is a home port for the oil industry and a transit harbor for timber, cars and other goods on their way to Russia. To provide access for larger vessels it had to deepen the existing channel by two meters to 12 meters and create a new channel section. Terramare Oy, a subsidiary of Royal Boskalis Westminster, won this assignment in late 2008. The project started in July 2009.
