Shell Malikai

Malikai is a deepwater oil discovery in offshore Sabah, Malaysia where Sabah Shell Petroleum Company is the designated Operator. A floating Dry Tree Unit (DTU) will be installed over Malikai field utilizing a Tension Leg Platform (TLP) design that suits the Malikai environment.

The 27,500 MT Malikai TLP is to be located about 110 km off the shore of Sabah (East Malaysia) in the South China Sea in water depth about 500 m. Boskalis was awarded a contract in 2014 for the provision of the Heay Transport Vessel (HTV) for loadout and float-off package of the Project which includes loadout of the Integrated Malikai TLP from MMHE fabrication Yard into HTV, Dry-transport to Johor Buoy, Float-off, Tow back and Re-delivery to TMJV at MMHE fabrication yard.

SCOPE

  • Loadout, Transport and Float-off Engineering
  • Design, construct and installation of grillages, skid beams and seafastening Preparation and Mobilization of White Marlin
  • Ballasting of the HTV during the skidded loadout operation
  • Provision of marine spread for the float off operation
  • Demobilization of White Marlin and reinstatement

PROJECT CHALLENGES
Technical challenges included the ability to adapt and successfully perform:

  • The discharge of the TLP offshore in Desaru instead of the original location of Johor Port;
  • The loadout of the integrated TLP ballasted instead of un-ballasted prior to loadout
  • The outfit of a HTV in Vietnam for the first time

NINA
The project was executed without incident. The NINA initiative was not only inculcated within the Boskalis PMT but also with key subcontractors.

CONCLUSION
The success of the project was due to the strong colaboration between all parties. The loadout oper-ation had several difficult challenges; technically and operationally. However, this was all resolved through communica-tion and the close cooperation between TMJV and Boskalis, which ensured that the TLP was still loaded in a safe, operationally sound and timely manner.

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.
