Project Requirement:• 8 Pipelines• 2 Fiber Optic Cables

Bottom Pull Method (Landfall to Landfall)Project Example

Tanjong Penjuru(Singapore mainland)

Shell Bukom

Refinery (BukomIsland)

Installation Concept:• Build Pipeline & Cable

Bundle at Bukom• Bottom Pull across

Shipping Channel• Protect with Rock Berm
