New Orleans

Project: Shoring Tower Protection in New Orleans, Louisana
Summary: During widening of Huey Long Bridge, false-works are used for the erection of bridge trusses. The tasks involved included the design of protection barrier from impact of a runaway barge. A structure consisting of barges, sectional barges and piles were designed to absorb the energy through plastic deformations.

 

BPZ Energy

Project: BPZ Corvina Field in Peru
Summary: The study included determination of the mooring system to hold 25,000 to 80,000 DWT tankers in 59 m water depth using OCIMF criteria.

 

 

Abu Dhabi

Project: 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

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

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

Project: Mooring Spud Design for Trinity Drydock, Texas
Summary: Mooring Spuds have been designed to work with the dry dock carrying 39,700 DWT tanker with a design wind speed of 90 knots.

 

Mobil Refinery

Project: Mobil Refinery in Port Arthur, Texas
Summary: The project was involved in the design of Mooring and Berthing Dolphins for loading and unloading of tankers. Additions to dock facilities were designed including the pile foundations and dock structure. The design calculations were in compliance with OCIMF criteria.
