The breasting dolphins were constructed as fully in-situ, reinforced main dolphin structures with rebates to accommodate the installation of precast fender panels. Each of the two fender panels is made up of three, 63 ton precast fender units, which after installation were made monolith with the dolphin by in-situ infill pours.
All precasting works were done on site with only the approach trestle prestressed beams being constructed off site.
The loading arms, the gangway tower, fenders and quick release hooks, which will secure the FSRU to the jetty, are due to complete in early February.
In terms of the process equipment, the gas metering/chromotograph has been installed and the HIPPS and safety shutdowns systems are in transit to the project in readiness for installation later this month.
“Part of our scope of work is to install and commission the gas metering and analysis system – which will be used as the fiscal metering system by which both Golar and FAJR are paid,” said McDonagh. “The chromatograph takes samples of the gas and analyses the chemical composition of the supplied NG to determine the calorific value – its burn value. It also measures accurately how much gas is passing through the line.”
The meter was ‘wet’ tested for accuracy prior to delivery and achieved an accuracy of 10 times better than that required by the client, said McDonagh.
Another aspect of the project is the existing timber jetty, which the JV is to renovate and extend to form the new tug berth. Access to this section of the works is currently restricted as the jetty is being used temporarily by liquefied petroleum gas (LPG) carriers in advance of them moving to a neighbouring LPG terminal.
The original plan was to complete the construction of the tug berth and the associated administration building at the same time but the access issues have forced a rethink.
“We agreed with the client that we relocate the administration building, bringing it nearer to our current site and this has enabled us to build it as planned without delay,” said McDonagh.
“We are looking at the moment at how to accelerate the construction period for the tug jetty once the area is handed over to us. We’re already casting the precast units and all piling and tie rod materials are on site for the tug jetty works. We will have everything ready to go.”
The joint venture partners are currently progressing the terminal, administration and utility buildings works.
Internal and external finishes are also taking place.
The project is at its peak, with 400 people mainly working on mechanical and electrical works and the pipeline. Handover is set for early July. “The last 21 days of the programme cannot take place without the FSRU as that’s when we need the gas supply to do our hot commissioning,” said McDonagh.
