HOW CAN THE INDUSTRY COUNTERACT UNSCHEDULED DOWNTIME?

By Scott Smith, Regional Director (Asia Pacific), Trelleborg Marine Systems

One of the biggest issues in the market is keeping on top of downtime and maintenance – eight out of 10 ports suffer from unscheduled disruptions with almost half of these being ‘down’ for up to 10 per cent of the time. This was brought to our attention through a recent survey we conducted alongside Lloyds’ List with almost 400 port decision makers.

It revealed that budgets continue to be under pressure and maintenance appears to be suffering because of it. But it’s not all doom and gloom. Things are looking up as new technologies are being harnessed to help overcome issues with port safety and maintenance.

You can download our survey report in full from http://www.takesthepressureoff.com/barometer2 but if you’re short on time my colleagues and I have put together a series of short videos so you can digest the key findings in more bite-size chunks.

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.
