Greater Bongkot North Flare Tip Replacement

Flare tip handling offshore Thailand

Conbit's recent project, in collaboration with partner CR3, involved flare tip replacements for the end client PTTEP in Thailand. The endeavor featured the adept use of specialized equipment such as electrical winches and a client air-driven winch, alongside client davits and Conbit's own gantry system. Guided by experienced on-site managers, the project yielded exceptional results and garnered high praise from PTTEP for its efficiency and quality execution.

PTTEP emphasizes safety

PTTEP Energy Development Company Limited enlisted the expertise of CR3/Conbit for flare tip replacements on the Greater Bongkot North (GBN) platforms, situated approximately 250 km east of Songkhla in the Gulf of Thailand. Owned and operated by PTT Exploration & Production, the Bongkot field comprises six main interconnected platforms: Production Platform (PP), Riser Platform (RP), Quarter living Platform (QP), Wellhead Platform 1 (WP1), Sour Production Platform (SPP), and Flare Platform (FP).

Flare tip replacement

The project's primary focus lies on the replacement of high-pressure (HP) flare tips on the FP and SPP towers, alongside maintenance of the low-pressure (LP) flare tip on the PP tower. Utilizing mechanical handling devices, lifting tools, including davits or (backup) gantries, the project aims to execute precise operations for enhanced safety and efficiency. The specific scopes encompass the replacement of two HP flare tips on the FP vertical flare tower, the HP flare tip on the SPP Inclined flare tower, and the LP flare tip pilot and wind shield on the PP vertical flare tower.

Specialized flare tip handling crew

The project necessitated a sizable crew comprising over 25 technicians, encompassing a mix of local talent and European expertise. This extensive workforce was essential due to the simultaneous execution of works during a brief shutdown period across three distinct locations on the Greater Bongkot North platform, situated offshore Thailand. The collaborative effort of this diverse team ensured the seamless coordination and timely completion of tasks, underscoring our commitment to efficiency and safety in every facet of the project execution.

See how we got to work

Lifting gantry is used by Conbit to lift the old flare tip off and the new flare tip on the flare tip access platform.
Sometimes the davit system that is installed on top of the flare tower can be used to replace flare tips. This requires thorough load testing at the start of the shutdown.
DP2 is often required in offshore lifting operations. Conbit lifts from a fixed platform directly to a supply vessel. The position of the supply vessel is critical.
Coinbit uses light weight modular lifting systems that can be erected by hand. Several systems are used to finally install the main lift syste..
A light set of rigging equipment is used to install the main flare tip handling system. There are gantry type or single pole flare tip handling systems available iwthin the Conbit fleet.
Offshore lifting of flare tips requires specialists and carefull planning.
