SCHIEDAM, the NetherlandsHuisman has won new contracts for 10 pipelay systems from various offshore pipelay contractors.

The company is supplying three 550-metric ton (606-ton) tiltable lay systems (TLTs) and two 650 and two 340-metric ton (716 and 375-ton) TLTs for Technip-DOF, both to serve Petrobas projects.

Technip-DOF’s order includes baskets and two 50-metric ton (55-ton) SMST knuckle boomcranes to allow for deck handling and deepwater operation. In this case VARD will build the associated vessels in Norway and Brazil, with delivery of the final pipelay system scheduled for early 2017.

Subsea 7’s equipment will feature a system designed by Huisman to control squeeze loads. Additionally, all tensioners will be retractable, assisting safe installation of large components such as umbilicals, risers, and flowlines. The vessels deploying the equipment will be built by IHC Merwede in the Netherlands.

For Subsea 7, Huisman will also supply a 325-metric ton (358-ton) vertical lay system (VLS) and a 600-metric ton (661-ton) active heave compensated subsea crane for a new DP-3 heavy construction and flexible pipelay vessel to be built by Hyundai Heavy Industries. Huisman is expected to deliver the equipment in 2015.

Finally, the Dutch contractor is providing pipelay systems for Ceona’sPolar Onyx and Ceona Amazon, the latter to be built by Lloyd Werft.

Ceona Amazon is a multi-function, dynamically positioned  construction vessel based on a Huisman design, with strong seakeeping characteristics and maximum deck area. The design includes a project area of 4,600 sq m (49,514 sq ft), allowing for further storage of line pipe and standard flexible installation reels.

The pipelay system will comprise an inclinable lay spread with a top tension of 570 metric tons (628 tons) and a rigid pipeline firing line system. The vessel will be equipped to lay rigid and flexible pipelines and umbilicals, and to install large subsea structures using one or both of its 400-metric ton (441-ton) subsea cranes, also built by Huisman.

All equipment is expected to be delivered in 2014, along with a 275-metric ton (303-ton) VLS for thePolar Onyx.
