During a site shutdown, Conbit was tasked with replacing the and existing 3,040kg flare tip with a new 3,904kg flare tip on the Marlin B platform in Australia.
The Marlin Complex EP, consisting of Marlin A and B, is a hydrocarbon production facility located 42 km off the Gippsland coast, Australia.
Having developed a reputation in the industry for their flare tip replacements Exxon Mobile awarded Conbit for the work. The preparation and planning stages, which also tested the feasibility of the mechanical handling method, provided the client with the confidence that the replacement of the flare tip would be carried out successfully.
Conbit prepared extensively. During the structural design and engineering phase considered the environmental conditions, such as temperature, wind and sea state. A feasibility study was also carried out, which indicated that the flare tip and lifting system could be carried by the flare tip access platform.
Safety meetings were planned in advance, ensuring all crew members were fully trained and briefed.
Conbit opted for a drop-and-lower-to-the-supply-vessel solution, whereby the flare tip was handled on the flare tip platform by a gantry-type lifting structure. The gantry lifted the flare tip over the edge of the platform and lowered it onto a supply vessel using a lift line. This lift line, coming from a winch installed on one of the platform decks, connected to the structure underneath the flare tip platform.
