VIDEO: Matrix delivers buoyancy structure to LNG project

LNG Industry,


Matrix Composites & Engineering (MCE) has delivered one of the world’s largest installation buoyancy structures to Heerema Marine Contractors (HMC).

The structure weighs 103 t and provides 150 t of uplift in seawater, the equivalent of eight large public buses. Constructed from a modular design, the buoyancy system (IsoBlox™) can be assembled in almost any 3D configurations, to meet challenging requirements. The structure forms part of a modular installation buoyancy package and will be used to deploy HMC's subsea production equipment used on a major LNG project offshore Western Australia.

Safe installation

The modular installation buoyancy package will be used in conjunction with HMC's installation vessel Aegir. Together, they will ensure the safe installation of the Flowline End Termination (FLET) and In Line Tee (ILT) structures onto the seabed, 250 m below water. The largest buoy in the package will be used to install the ILT and associated pipework.

Matrix's modular installation buoyancy structures (IsoBlox™) are assembled from a number of standard elements. The 150 t buoy is made up of 72 standard elements held in place with a through member. The structure is 12.3 m high, 6.44 m long and weighs 103 t.

Comments

Matrix's CEO Aaron Begley, commented: “There is nothing like our buoyancy in the market today. The standard element design means clients can take advantage of significant cost savings over customised designs. The modularity of the design means that in most cases, only one set of modules needs to be purchased in order to satisfy an entire set of requirements. This represents a significant cost savings for clients as well as eliminating the time factor involved with manufacturing new buoyancy as client requirements change.

“Using our advanced syntactic foam buoyancy system which has made Matrix a global technical leader in the manufacture of riser buoyancy, clients can be assured of a quality, reliable product".
