OSA Ice Barge

Project description

Oil Search Alaska is pursuing the Pikka Development in the north of Alaska. This requires drilling of wells, construction of facilities and infrastructure, and subsequent production operations to produce and transport crude oil.

To support the facility, a Seawater Treatment Plant is to be provided on a barge to provide water injection facilities at the facility. This barge will be floated into a graving dock and ballasted to rest on the seafloor.

Sealand coordinated the T&I activities and interfaces of the barge from Batam, Indonesia, to South Korea for integration and onward dry tow to Alaska for final wet tow into position.
