Aquatic deploys reels for offshore Venezuela pipe replacement task

Offshore staff

ABERDEEN, UK – PDVSA, Roffco, and IMR Global Supply have completed what is claimed to be the first project to replace large-diameter steel oil pipelines with flexible oil lines in Lake Maracaibo, Venezuela.

IMR performed the installation using the purpose-built vessel Zumaque Tracer. Aquatic Engineering & Construction provided technicians and equipment to handle and deploy the pipelines, and project management, engineering and operational support.

Lake Maracaibo is a large brackish bay connected to the Gulf of Venezuela by the 55-km (34-mi) Tablazo Strait at the northern end, and fed by numerous rivers, the largest being the Catatumbo. The lake is a major shipping route to the ports of Maracaibo and Cabimas.

The first part of the installation took place in late 2015 using 18 reels supplied by GE Oil & Gas/Wellstream. These comprised eight reels of 9-in. ID pipe and 10 of 12-in. ID pipe on 28-ft (8.5-m) diameter 200-metric ton (220-ton) reels.

The Wellstream reels and Aquatic equipment spread – a 500-metric (551-ton) ton modular drive system, 50-metric ton (55-ton) tensioner and ancillary equipment, were loaded at Port of Blyth, northeast England, onto the transportation vessel, HC Paulina for shipping to Ciudad Ojeba, Venezuela.

On arrival, all equipment was transferred to the installation vessel.
