TELFORD 31

Suitable for both shallow and deepwater operations, Telford 31 (ex Jascon 31) combines strong offshore construction capability with accommodation for up to 469 people. With 1300m2 of unobstructed deck space and a 400t capacity active heave-compensated deepwater crane, she offers extensive subsea support services for a wide variety of projects.

T31 has delivered accommodation services for BP/Modec PSVM to support the Hook-up operations of turret moored FPSO on Block 31, offshore Angola, and by BW on Sendje Berge FPSO, offshore Nigeria.

Telford 31’s deepwater crane capabilities were used by Exxon on the Erha project in Nigeria for the installation of suction piles and subsea manifolds.
