While transporting a service rig down a public highway, a set of aluminum stairs bounced off the load and landed on the road, impacting a third-party vehicle. The incident resulted in injuries to the occupants of the third-party vehicle.

A crew was in the process of rigging in a third-party hydraulic catwalk. A worker was positioned at the end of the pipe swing arm support (swing arm) to pull it away from the catwalk. As the swing arm was pulled away, it suddenly dropped approximately two feet and the leveling jack struck the top of the worker’s foot above the toe protector area. The worker sustained a fractured foot.

A coil tubing crew was running a fibre optic string into a production well. While placing the coil tubing into the well, the blowout preventor (BOP) separated from the wellhead. This resulted in damage to the coil tubing and loss of well control protection.

A crew was called out to a fire at a heavy oil well site when hydraulic oil leaked onto an engine exhaust manifold. While no one was injured in the incident, the fire destroyed an engine skid, hydraulic system and associated equipment.

A crew was hydrotesting a newly constructed pipeline when an incident occurred. During pigging operations, hydrotest fluid and the pig became lodged. While the crew dewatered and depressured the equipment, a large volume of air inadvertently escaped into the adjacent 400-barrel production tank. High pressure in the tank blew off the tank lid and vent lines. No one was injured in the incident, but it could have resulted in severe or fatal injuries to workers in the surrounding area.

A coiled tubing crew was conducting pressure tests of the blowout preventer. Following a successful low-pressure test the line was bled down. This pressure was bled off without issue. At this time, a high-pressure test was conducted. When the valve was feathered open to bleed off the pressure, a loud bang was heard, and the piping parted. Several workers were in the vicinity of the flying debris, but nobody was injured.

A heavyweight drill pipe dropped to the floor and fell toward the driller's controls. The top of the pipe struck the doghouse and bounced, throwing the worker into the steam manifold. The pipe slid down the doghouse, through the railing, across the mud tanks and into the track hoe, missing the operator.

A worker fell to the ground while standing on the track of the dozer loaded on a trailer.

As a worker was lifted by a boom hoist, the line caught on a hook handle or dog ear at the bottom of the doghouse, wedging the worker underneath it.

During a wellbore service in the winter months, a high-pressure gas release occurred.
