FAST-TRACK QATARGAS INSTALLATION

Fast-track qatargas installation

Vessel sizes have increased immeasurably in recent years and, on the back of that, so have the stresses exerted on port infrastructure. But replacing these systems can be problematic. Especially in the LNG sector where port downtime is an absolute premium due to the value of the commodities being shipped.

A prime example, is a recent project we worked on with Qatargas where three parallel motion fender systems were required for a fast-track project. The installation was completed in just four days to minimise disruption to their daily operations.

The project was carried out with specialist oil and gas contractor, Qatar Engineering and Construction Company WLL (Q-Con), with two sets of dual SCN1000 cones installed behind each Parallel Motion Fender Structure.

Completion of the project has enabled the global LNG supplier to upgrade an existing berthing structure, originally designed for vessels with a displacement of around 110,000 tonnes, to facilitate berthing of larger Q-Flex vessels with a displacement of about 150,000 tonnes.

Our Trelleborg parallel motion fender system was specified as it complemented the design of the existing jetty, raising its energy absorbency capacity and enabling it to facilitate the berthing of a much larger vessel, with increased weight.

The existing jetties weren’t originally designed to take the berthing energy and related reaction forces associated with the larger Q-Flex vessel. So we recommended the parallel motion fender system as it can offer 60 per cent greater force absorbency than a conventional fender without raising the reaction force above the allowable level, which meant that the existing dock could be used, for a much heavier vessel.

PORTS PRIMED FOR INVESTMENT SURGE

Ports primed for investment surge

It’s immensely pleasing, despite the global downturn, that port owners contractors and consultants are optimistic enough to predict that capital expenditure will rise or at least stay the same over the next 12 months.

At least that was the view of most (55%) decision makers we polled last year as part of a comprehensive market report on the ports, harbours and terminal sector. The Barometer Report, conducted with Port Strategy magazine, also revealed that operational expenditure will remain at current levels or increase with 60% backing this claim.

The apparent optimism is good for the market and good for the economies of the world, which need investment in the global ports to drive trading growth. But I must also sound a note of caution. While the short term outlook is much improved, our research also reveals that these decision makers don’t necessarily expect investment to return to the levels we enjoyed a few years ago. Almost two thirds think it could be less or, at best, static.

The risk of this is only too real. There is a fear that not enough investment will come through to offset the reduction in maintenance we’ve witnessed during the global recession. Ports, harbours and terminals need to embrace the ethos of making adequate investment now to ward off the future costs of downtime.
