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.

Port development,
Libreville - Gabon

A new area was constructed in the Port of Libreville for a mineral terminal, dry dock, fishing port, processing facilities and other port activities, such as aggregate processing. This new port development was required to improve and strengthen the logistic capacity for the inland mining industry, to reduce export costs, and thus to increase the competitiveness of mineral exports from Gabon.

Butendiek OWF

Boskalis was contracted by OWP Butendiek GmbH & Co. KG to supply, install and protect (by post-lay burial) the high-voltage inter-array cable at the offshore wind farm of Butendiek. This German wind farm is situated in the German Bight (Nordsea), approx. 35 km west of the island of Sylt. The 33 km2 wind farm consists of 80 wind turbines with a capacity of 3.6 MW each and a total capacity of 288 MW. The inauguration of the wind farm took place on September 8, 2015. It provides renew-able energy to approx. 370,000 households.

Cleanup sediment treatment, Fox river

As a result of industrialization the riverbed of the Fox River (Wisconsin, USA) had become contaminated with PCBs (polychlorinated biphenyls). Joining together a number of large paper mills based on the banks of the river have established the Fox River Cleanup Group to handle the remediation project. The site is on the federal Superfund program’s National Priorities List.

Cieg GJ1 Cable repair

Channel Islands Electricity Grid, a joint venture between Jersey Electricity and Guernsey Electricity operate several interconnecting power cable systems (power and telecom) between Jersey, Guernsey and France. Both Jersey and Guernsey rely upon the services of these interconnecting power cables and as a consequence there is a demand to reduce the possible effects and impact of failure to these interconnecting power cables. Boskalis were contracted to conduct a preemptive repair replacing a section of cable including the installation two subsea joints on the Guernsey Jersey circuit, close to Havelet bay.
