Metsec, a UK-based cold roll-forming company providing products for construction and manufacturing industries, has delivered the largest purlins project for a major infrastructure project by Qatari marine company Nakilat.

Nakilat provides the critical transportation link in Qatar’s liquefied natural gas (LNG) supply chain and services to vessels in Qatari waters besides overseeing the activities of the country’s shipyard.

Nakilat Damen Shipyards is an integral component of the supply chain of some of the largest, most advanced energy projects in the world undertaken by Qatar Petroleum, Qatargas, RasGas and their joint venture partners for the state.

Metsec said the fourth phase of the Nakilat shipyard project involves construction of three buildings, a hall, the depot and the assembly building.

"With its capability to roll the long spans that were required on the project, Metsec not only delivered 15-m clear span sections, but was able to provide full design support throughout the 12-month project, even altering operational hours in the UK to accommodate the time difference in Qatar," stated a senior official.

"Part of Metsec’s design offering was undertaking the structural calculations for the project. This meant the project could be value-engineered which reduced the sections sizes required on the project without compromising on strength or performance," remarked Rob Marsh, the commercial and technical manager for Metsec Middle East.

"We pride ourselves in delivering high quality, engineered solutions to our customers and at the most cost-efficient price possible," he noted.

Originally designed using Metsec’s heavy end bay system, with the 342Z25 section in the end bays and the 342Z23 in the internal bays, Metsec’s design team reviewed the project design and advised that the specification was overdesigned.

As a result, the Metsec team value engineered the project, designing a bespoke 342Z20 section for the internal bays, and the 342Z30 section for the end bays. This value engineering resulted in a 15 per cent reduction in the weight of the roof, giving the client a more cost effective solution.

In total, Metsec provided more than 1,000 tonnes of steel to the project, the largest project for the Purlins division to-date.

Marsh said Nakilat Damen Shipyard was the largest purlins project Metsec had undertaken and involved a lot of intensive design work to ensure the sections could accommodate the long spans and to deliver on time and in full to the client.

“On the success of this project, Metsec was then awarded the next phase of the project, a superyacht facility,” he added.

The company had earlier supplied key products for a number of notable projects in the region including Abu Dhabi airport and Warner Brothers theme park on Yas Island.-TradeArabia News Service
