The hybrid design of MPSVs enables them to support shallow and deepwater subsea construction and accommodation projects
Acquired from Sea Trucks Group Limited last year by Dubai-based Telford Offshore, its four new multi-purpose support vessels (MPSV) with dynamic positioning class 3 capability have proven extremely versatile. In deep and shallow-water fields, these vessels can perform heavy lifting, fabrication and installation, while providing high-capacity accommodation. They can also be deployed to greenfield and brownfield developments.
Mexican offshore construction company Grupo Protexa has chartered three of the MPSVs for a total of 400 days to support state-run Pemex’s Litoral de Tabasco project in the shallow waters of the Bay of Campeche within Mexico’s Southern basin. The vessels will be deployed on a shallow-water engineering, procurement, construction and installation (EPCI) project for multiple lightweight offshore platforms and pipelines.
Telford Offshore chief operating officer Duncan MacPherson says: “These significant shallow-water contracts awarded by Protexa illustrate the versatility of our fleet of DP3 vessels, which are capable of supporting multiple activities, focusing on high-capacity accommodation combined with pipelay, lifting, subsea and installation services.”
“While it may look like an ugly duckling, Telford 31 is built to a distinct hybrid design that combines high accommodation capacity and deepwater construction capabilities”
Telford Offshore will deploy Telford 31 (ex Jascon 31), Telford 34 (ex Jascon 34) and Telford 28 (ex Jascon 28) for the project, with each vessel accommodating 300 people on board over the course of the project.
While it may look like an ugly duckling, Telford 31 is built to a distinct hybrid design that combines high accommodation capacity and deepwater construction capabilities. It was used to install suction piles and subsea manifolds at water depths in excess of 1,000 m in support of ExxonMobil’s Erha Project in Nigeria.
Already working in Mexico with Protexa on another project, Telford 31 will mobilise in July 2019 for the new contract, which includes scope for multiple subsea and topside activities. Telford 31 is equipped with a 400-tonne capacity heave-compensated main crane, a heave-compensated gangway, a moonpool near midship and 1,300 m2 of unobstructed deck space.
The Bay of Campeche is familiar territory for Telford 31. From September 2015 to February 2017, it was deployed on Pemex assets for two long campaigns consisting of accommodation, lifting, topside modifications, pipeline repairs and simultaneous operation services for Permaducto, part of Grupo Protexa.
Telford 34, currently deployed in Mexico for another client, will mobilise for Grupo Protexa directly after completing that contract and will undertake multiple rigid pipelay and topsides works. The pipelay, offshore construction, SURF, accommodation and hook up vessel is equipped with an 800-tonne capacity heave-compensated main crane, an S-Lay system for pipes of 4- to 48-inch diameter, a heave-compensated gangway, a moonpool and 1,300 m2 of unobstructed deck space. Telford 34 also has a 55 m stinger supported by an A-frame for laying offshore pipelines.
As a pipelay vessel, Telford 34 completed an EPCI assignment for the Total Anguille pipeline project, off Gabon, that required the design, procurement and installation of a 32 km, 18-inch pipeline between the Torpille and Anguille platforms at depths of 30-40 m.
Telford 28 has been deployed on multiple accommodation and hook up service projects around the world, supporting such projects as the Saipem – FPSO Cidade de Vitoria for Brazil state oil company Petrobras’ Golfinho ultra-deepwater field and ExxonMobil’s Kizomba B deepwater field in Angola. Telford 28 is currently being mobilised to the Gulf of Mexico, where it will execute hook-up work with another client, then undertake multiple subsea and topsides works for Protexa. The vessel is equipped with a 270-tonne capacity main crane, a heave-compensated gangway and 1,100 m2 of unobstructed deck space.
