Port and MOF, LNG plant Barrow Island, Gorgon

Design and construction of a new port and materials offloading facility in a class 'A' nature reserve. The project owner is developing LNG process facilities on Barrow Island off the north west coast of Western Australia approximately 140 km west of Dampier and 95 km north east of Onslow. Barrow Island is a Class A Nature Reserve and an internationally important conservation estate.

Scope of work

Boskalis’ scope of work on the project included:
  • Detailed design and construction of a Pioneer Materials Offloading Facility (PMOF).
  • Design and construction of abutment structures for a Ro-Ro berth, module carrier berth and barge berth.
  • Design and construction of mooring dolphins and access walkways for the PMOF barge berth, module carrier berth and Ro-Ro berth.
  • Dredging and reclamation work for the approach channel, turning basin and berth pockets associated with the construction of the MOF.
  • Dredging for the LNG jetty area including an approach channel, turning basin and berth pockets.
  • Installation of temporary and permanent navigation aids including two permanent front and rear lead support structures.
  • Provision and operation of a Marine Construction Support Vessel to accommodate personnel involved in the Project.
  • Construction of the Eastern Materials Offloading Facility (EMOF) causeway including all armour rock, construction of a breakwater, placement of X-blocs and installation of concrete nib wall.
  • Compaction of the EMOF (Cofra).
  • Materials testing (Boskalis Environmental).

Dredging and reclamation works

The dredging works consisted of 2 major parts:
  • A MOF access channel and turning basin to create access for heavy load transport vessels to bring in construction materials and large modules for the construction of the LNG plant on Barrow Island.
  • An access channel and turning basin for the LNG carriers once the plant is operational.

Rock protection and breakwater works

These works consisted of 3 major components:
  • Design and construction of a protection of the MOF platform against cyclonic waves with rock only.
  • Construction of a protection of the EMOF platform against cyclonic waves with rock underlayers and concrete X-blocs.
  • Construction of a breakwater for protection of a tug harbour against cyclonic waves with rock underlayers and concrete X-blocs.

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.

Land reclamation, North Manama Causeway

The purpose of the project was to provide additional land to accommodate a section of a proposed new highway system to service the area and to relieve congestion on the corniche road. Boskalis appointed Hydronamic (the in-house engineering department of Boskalis) to provide detailed design and on site assistance with supervision of the sub-contractor for the rock works.

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.
