Grenland Group has over the last three decades delivered more than 30 burner booms of various kinds. We can customise a boom to suit the exact specification given by the buyer, or develop a customised specification.
By selecting one of our standard boom designs, price and delivery time can be reduced significantly, compared to having a completely new design engineered and fabricated. Normally, only small adjustments on the rig or the boom are required to utilise a standard boom.

Weatherford’s offshore burner boom assembly facilitates safe disposal of produced hydrocarbons, protecting the rig and personnel onboard. The burner boom is a lightweight, U-shaped structure designed to carry the necessary pipework (dedicated lines for oil-condensate, gas, water, compressed air) for produced-hydrocarbons disposal through the burner heads and gas flare, at a safe distance from the offshore host facility (rig). It also provides a safe passageway for personnel. Typically, two booms are deployed at opposing sides of the rig to accommodate changes in wind direction. The boom is mounted on a swivel at the base of the king post, which is fixed to the rig. The boom-hanging cables are attached to a pivot assembly at the top of the king post, and the wind-stay cables, which prevent lateral movement of the boom, are fixed to the rig.
The modular design gives the option for a 60-ft (18.3-m) or 90-ft (27.4-m) boom length, depending on the heat radiation and loading expected during the well-test flow periods. The burner-head assembly is located on a platform at the end of the boom, and the gas flare
line extends beyond this platform. For cooling, water screens are incorporated to minimize the heat radiation, thereby protecting the rig and personnel onboard.
Moreover, the rig typically has fixed or temporary water screens at its perimeter for additional protection.
Features, Advantages and Benefits
• Two- or three-section, lightweight, modular design optimizes the distance from the rig to minimize heat radiation and noise and facilitates shipping.
• Integral water screens provide cooling to reduce heat radiation to the rig.
• Fixed, welded pipework along each section of the boom eliminates potential leak paths, enhancing environmental safety.
• Boom sections are connected by hammer unions for easy makeup.
• The king-post design enables the boom to be swung parallel to the rig during drilling operations and rigmoves for minimized handling and personnel safety.

During an offshore well testing operation, TETRA’s burners efficiently combust oil products at the surface in order to avoid oil storage and minimize pollution problems. Burners are installed on 13.7- to 27.4-meter (45- to 90-foot) long booms to limit the heat radiation to the offshore installation and keep flares at a safe distance.
Each boom has a walkway to its burner. Boom plumbing includes an air line for efficient combustion, a water line for minimizing heat radiating towards the installation, a relief line from pressure relief valves on various testing equipment and a flare line. The boom is mounted on the rig with base plate guy lines and the king post. Horizontal guy
lines are used to orient the boom, and vertical guy lines are fixed to the
structure of the rig (king post) to support the boom.

The boom structure is welded lattice boom construction by steel square tube with handrail and grating for access
The foundation supports the rotating part of the burner boom and welded to the Rig.
The lower end part of the foundation is beveled for weld connection to the Rig.
The pipes are installed on the support which is welded in the burner boom and fixed by U-bolt. All kinds of pipe connection types are
flange connected type and between the flange of pipes end where mounted in the burner boom and flange of pipes end where mounted
on the rig, the swivel is bolted to each of the flange with tightening by torque bolts.
The swivels are enable to pipe rotate without leakage and damage.
The slew bearing used in the burner boom from high quality maker and of the single ball bearing type requires specially designed and
calculated for use on drilling rig burner boom.
The slew bearing is capable of with standing all axial and radial forces and the resultant overturning moments.
The hydraulic cylinders for rotating the burner boom are specially built for the use in the offshore environment and consist of a quality
chrome protective piston rod and spherical bearings.

U burner boom is a modular design, basically consisting of two sections that extend approximately 18 m [60 ft]. By adding one or two intermediate sections, the boom can be lengthened to about 27 m [90 ft] or 36 m [120 ft].
The structural design of the U-boom allows access to the burner and supports pipes that are laterally positioned on the boom sides. These pipes supply the burner with air, water, oil, and propane.
The U-boom is mounted on the rig with a rotating base plate and guy lines. Horizontal guy lines help orient the boom; and vertical guy lines, which are fixed to the rig’s main structure, support the boom. The rotating base enables horizontal and vertical positioning of the boom and burner. The boom is positioned slightly above horizontal so that any oil left in the piping after flaring operations does not leak out and cause pollution.
Provide support for the burner and piping.
Allow access to the burner and piping.
Reduce heat radiation.
Protect rig personnel.
Limit burner noise on the rig.
Suitable for H2S service
Available in two or three sections
Piping for oil, water with filter, air with check valve, and propane, in addition to one gas flare
