TRELLEBORG SUPPLIES SMARTPORT SOLUTION TO SHELL’S PRELUDE FLNG

By Richard Hepworth, President, Trelleborg’s marine systems operation

I’m delighted to reveal that we have supplied our SafePilot solution, Ship Shore Link (SSL), Electrical Shutdown Link (ESL) and radio ESD for tandem condensate offload to Shell’s Prelude FLNG facility, the largest offshore facility ever constructed. Prelude, which is a staggering 488 meters long, 74 meters wide, and made with more than 260,000 tons of steel, is designed to extract and liquefy natural gas from a site in North West Australia.

We’re proud to have supplied our gas transfer technology and SafePilot navigational and piloting systems to such a large-scale project. The products supplied fall under our SmartPort product range, representing the leading technology we use to enable real time communications and information sharing during vessel approach and transfer operations.

In support of Prelude’s process operations, we supplied our industry-leading SSL system for the transfer of LNG from the platform to visiting LNGCs. In addition, we also provided ESL, known more commonly as the SIGTTO link, for LPG transfer. A new radio ESD link, developed with Shell, was used in conjunction with floating hoses for the tandem transfer of natural gas condensate produced as part of the LNG production process.

We also supplied the navigational system to Prelude, designed to closely monitor the relative motion of the FLNG and the carrier during approach, and the sideways berthing/mooring phase as well as a tandem berthing/mooring phase. The motion and position data of the carrier were measured by the Differential Global Positioning System (DGPS) / Globalnaya Navigazionnaya Sputnikovaya Sistema (GLONASS) RTK based Portable Pilot Units (PPU) which was installed on the bridge wing of the gas LNGC.

The PPU is our “all in one” unit with built in roll and pitch sensors. The CAT III unit is quick and easy to set up, as it only contains two GPS antennas and the PPU switches on automatically the moment the antennas are pulled apart.

The position and motion data of the FLNG is measured by the Motion Reference Unit (MRU) and the DGPS / GLONASS RTK based base station on the FLNG. The base and up to five PPUs were linked via a dedicated UHF frequency.

The offshore operation required our precise approach, monitoring and mooring software for the offshore oil and gas industry. This was done by the SafePilot system, the pilot, master, tug operator and control room all having access to a real-time, accurate and independent picture of the relative positions and movement between the different objects and tankers in operation. Our offshore software allowed the ability to view all objects and shuttle tankers together, on a single display.

LOOKING FORWARD TO THE FLNG WORLD CONGRESS 2015!

Alistair Traylen, Chief Systems Architect, Docking and Mooring Group

At the end of June, I’ll be speaking about developments in the ship-to-ship approach and berthing systems for FLNG at the FLNG World Congress in Singapore.

My presentation will form part of Stream D at the congress, covering ‘Flexible Technology Applications for Cost-Effective FLNG Operations’, and I’ll be discussing technologies, developments and the integration of the ship-to-ship approach and berthing systems, and how they are applicable in the FLNG market.

There are a number of complexities introduced to approach and berthing in ship-to-ship operations, and further arise in the LNG arena. As the FLNG market grows, docking and mooring technology and systems integration need to evolve rapidly to keep up with it.

In particular, I’ll talk about the complexities of banked mooring in terms of berthing and position monitoring, and how they affect the relative positioning requirements for FLNG ship-to-ship berthing. I will also outline considerations for specifying and evaluating ship-to-ship berthing systems.

I’ll leave you with some words from our President, Richard Hepworth, about why this rapidly evolving industry is so important to us, and I hope to see you at the congress!

“Trelleborg is a world leader in the design and manufacture of advanced systems for LNG applications, but we know that we need to continue to innovate to remain in this position.  One of the most valuable ways for us to inform about our developments is through peer-to-peer dialogue, which is just one of the reasons why we feel events like the FLNG World Congress are so important.”
