Revitalized Quaywall Plays a Key Role for Trinidad and Tobago Offshore Gas Production BergerABAM’s Houston staff worked on the Berth 2 quaywall project with Soletanche Bachy Cimas, a Colombia-based contractor and its French affiliate, for the National Energy Corporation of Trinidad and Tobago. The original facility was a cellular sheetpile structure, which deteriorated significantly and failed in some locations, affecting berthing operations and necessitating immediate reconstruction. BergerABAM’s reconstruction solution for the quaywall incorporated a tied-back H-Z combi-wall and involved exhaustive geo-structural modeling, analysis, and design. The quaywall was designed for various combinations of soil, surcharge, wave, and seismic loading conditions. Brighton Port’s Berth 2 quay wall facilitates launch of Juniper offshore platform in La Brea, Trinidad and Tobago.

In January 2017, British Petroleum (BP) launched its Juniper platform towards the southeast coast of Trinidad as part of its $2 billion start-up project. The platform topside, fabricated in La Brea, Trinidad (44 meters tall and weighing approximately 4,600 metric tons), was launched over Brighton Port’s reconstructed Berth 2 quaywall that was designed by BergerABAM. The entire launch event was highly covered in local and international media. The reconstructed quaywall serves Panamax-size vessels used for general cargo transfer and has the capability to launch large-sized offshore platform modules similar to the Juniper in the future.

The topside of the Juniper platform was launched over a specially designed heavy-loading area embedded within the quaywall. The heavy-loading area consists of an independent 24-inch-thick concrete slab supported on 48-inch-diameter steel pipe piles and is designed for a maximum distributed live load of approximately 150 kPa and crawler crane loads. An important design consideration was to provide the required pile geotechnical axial capacities because of the platform loads and prevent overloading of the reconstructed quaywall. As evidenced by the high-profile, seamless launch of the Juniper platform, it is anticipated that the reconstructed Berth 2 quaywall will play a key role in supporting offshore gas production and exploration endeavors.
