ICON Engineering performed geotechnical installation analysis, selected the suction pumps for installation of the suction piles and designed the ballasting umbilical system.

A diagram of the East Bunga Raya development concept

The platform to be installed was a Mobile Offshore Application Barge (MOAB) structure. The platform is used as a booster platform and is in 53.5m of water at the Bunga Raya field.

The facilities installation consisted of two floating components.

The East Bunga Raya BR-D substructure during ballasting for installation

The Substructure is a four legged floating jacket complete with integrated suction can foundations at the base of each leg.  The substructure was wet towed from the fabricators yard to the field.  The substructure was then ballasted down and lowered to the seabed using assistance from a derrick barge crane.  The pre-installed suction pumps were then used to complete the substructure installation.

The BR-D substructure under tow

The Substructure is a four legged floating jacket complete with integrated suction can foundations at the base of each leg.  The substructure was wet towed from the fabricators yard to the field.  The substructure was then ballasted down and lowered to the seabed using assistance from a derrick barge crane.  The pre-installed suction pumps were then used to complete the substructure installation.

The jackup legs were lowered down to stab in to cones on the substructure and then used to jack the 3120 t topsides to the design elevation.
