Vessel Exclusion Barrier in Abu Dhabi
Summary:
The project involved in the design of mooring system to hold floating security barrier in place under the impact loads of small craft trying to breach the barrier. The barrier is made of segments interconnected with locking modules, long gate for the entry of the vessels, supported by shore anchors. Non-linear time domain analysis was performed to study the dissipation of impact energy through global deformations.

Kiewit

Year:
2006
Project:
Canaport LNG Terminal Project at Canaport, Saint John, NB Canada
Summary:
The project involved several jacket structures in water depths of about 15 to 30 m. These structures are: one Loading Platform, 4 Berthing Dolphins, 6 Mooring Dolphins and 5 Trestle Bridge Supports. The project was for Kiewit Engineering.

ConocoPhillips

Year:
2002
Project:
ConocoPhillips in Veneauela
Summary:
Mooring tower was designed to secure FSO and shuttle tanker in 85 ft water depth for the Corocoro field development in Venezuela. Time domain simulation was performed to determine the hydrodynamic loads due to coupled multiple floating bodies. Monopile, three pile and four pile concepts were investigated. The tower was located in severe earthquake zone and the ground motion loads were included in the design of the non-linear link connecting the tower and the FSO. Risers and pipelines connecting to the tower were designed.

Trinity Drydock

Year:
1993
Project:
Mooring Spud Design for Trinity Drydock, Texas
