Modular Construction Technology for Arctic Islands

by V. M. Buslov, Brown & Root Int Inc, Houston, TX, USA,



Document Type: Proceeding Paper

Part of: Civil Engineering in the Arctic Offshore

Abstract:

In order to investigate the possibilities for application in the Arctic of new generation construction vessels, a conceptual design of a production island retained by crane-installed concrete modules was carried out. The advantage of the crane-installed modules consists in the fact that they are not required to maintain buoyancy during installation. Four various alternatives for transportation and installation of retaining wall were considered. The technical and economical analysis indicated that substantial cost savings may be expected due to the application of the very large transportation barge and large lifting capacity installation vessel. Besides direct cost reduction this technology precludes a number of logistic problems, associated with application of floating caissons. The paper describes the complete cycle of conceptual design for a proposed construction scheme in the conditions characteristic for the shallow-water areas of the Beaufort Sea.
