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...

Challenge: Vibrations in a refinery FCC unit led to repeated ducting failures. In addition, the gas traveling through the ducting was a source of excessive noise. Hopper Engineering Associates was retained to mitigate both noise and vibration issues in the system....

Challenge: Hopper Engineering is providing technical support for the removal of an offshore oil platform in Alaska. A new crane of larger capacity is required to handle the heavier equipment necessary for the platform removal process. The new crane pedestal sits...

Challenge: After several years of service in a corrosive environment at a refinery, many concrete piping supports were found to be in a state of deterioration, with cracked and spalled concrete, and exposed and corroding steel reinforcement. An investigation of all of...

Challenge: There is an aging fleet of platforms in the Cook Inlet. It is difficult to perform sub-sea inspections due to the site environmental conditions. As an alternative to sub-sea inspections, vibration monitoring can be used to determine structural damage....

Challenge: An offshore platform is converting the crew quarters building from wood framing to steel. In order to verify that a heavier building is a viable option, the capacity of the production deck, which the quarters building rests on, needs to be determined....

Challenge: A subsea crack was found on an offshore Alaskan oil platform built in the 1960s. The crack must be repaired while the platform remains in service. Resolution: HEA helped establish a repair option for the crack which included underwater welding. This is one...

Challenge: Hopper Engineering spearheaded the assessment and remediation of an offshore oil platform, located in Alaska, which was found to have a seven foot diameter tubular brace separated from the main jacket structure of the platform. Our primary tasks included...

Challenge: In an effort to address the declining output from wells in the Cook Inlet coupled with the anticipated future needs for natural gas in Alaska, an option is considered to offload compressed natural gas (CNG) at an existing liquefied natural gas (LNG)...

Challenge: A full platform assessment of an existing offshore platform in Cook Inlet, Alaska is required for a client. The structural integrity of the existing platform is to be evaluated per API standards for the deck loads, the environmental loads (including...
