Challenge: A refinery client uses seawater as the main supply for plant cooling operations as well as firewater for emergency situations. Depending upon storm activity and currents, significant seaweed and floating debris have been witnessed entering the intake...

Challenge: Design a support foundation for a large reheat furnace being installed at a local steel manufacturing plant to increase their production output. The weight of the new furnace is measured in millions of pounds, with dozens of individual support points for...

Challenge: A supply ship, the PSV Monarch, was involved in a collision with legs 1 and 4 of the Granite Point platform located in the Cook Inlet, Alaska. Due to damage to the ship incurred during the impact, the ship eventually took on water and sank. The incident...

Challenge: Ocean currents flowing beneath offshore platforms provide a wealth of energy that has previously gone untapped. Recent developments in alternative and renewable energy have provided a number of options for energy production, including tidal turbine...

Challenge: Assess the condition of a corroded Diesel Firewater Conductor Pipe (Caisson) located on an offshore platform. Determine if the caisson remains fit for service, if it does not then design a repair. Resolution: UT measurements were taken to determine the...

Challenge: Thinning of the weld material at a fin-fan outlet nozzle was identified during routine inspection. The client performed a Fitness-for-Service analysis in-house and found stresses in the component to be acceptable. However, per API 579 requirements the...

Challenge: As oil and natural gas wells in Alaska's Cook Inlet decline and the platforms used to capture the petroleum resources reach the end of their useful lives, operators are exploring options for the safe and efficient removal of the massive structures. HEA was...

Challenge: An aggregate reaction is causing ongoing degradation of the reinforced concrete structures at this facility. This main pipe rack is one of the more heavily deteriorated structures. The facility operator and regulators asked our team to estimate the margin...

Challenge: During a routine inspection of an offshore platform corrosion damage was discovered at various welds connecting horizontal braces to the pontoon. One of the horizontal braces was found to be completely separated from the pontoon with a gap of up to 1.5...

Challenge: The mud pumps on the production deck of a platform in Cook Inlet Alaska were replaced with heavier models. To install the new mudpumps, major support structure below the deck crane needed to be cut, temporarily, so that the new mudpumps could be maneuvered...
