Load-bearing modular buildings
Pivot-Lock load-bearing modular building systems support loads up to 125 lb/sq ft without the use of additional structural support columns.
The strength of these modular systems stems from the inherent strength of the panel. Panels are made with a framework of anodized aluminum structural extrusions for resistance to racking. The panel is mechanically fastened on both sides. Panels are pivoted and locked into place to form a tight-tolerance seal that helps maximize insulation qualities and provide sound attenuation.
These buildings are one option for adding work or storage space indoors where vertical open space is 17 ft or more. They are a viable solution where horizontal work and storage spaces are at a premium and vertical space is readily available for expansion, the company points out.

Dual gradient riser designed for ultradeep water
A new riser system is specifically designed for future dual gradient, ultra- deepwater environments.
This company's dual gradient drilling mud return marine riser system (DMRS) uses a new design to take advantage of dual gradient drilling and underbalance drilling without sacrificing the ability to be used as a conventional drilling riser system.
The new DMRS riser system offers advantages now for conventional drilling, among them are:
- High return fluid velocities. The higher velocity in the return line, relative to that which can be achieved in the riser pipe, makes it easier to carry the drill cuttings out of the well.
- Continuous flow over the shakers. The system minimizes the sporadic flow of return fluid over the shakers by eliminating variations caused by the motion of the telescopic joint.
- Reduced drilling fluid requirements. The DMRS reduces the amount of drilling fluid in the riser by two-thirds.
- Reduces the tension requirements of the riser. The reduction of drilling fluid within the riser reduces the tension requirements of the riser, reducing wear and maintenance on the tensioner.
- Environmentally friendly. The smaller volume of drilling fluid in the riser reduces the environmental impact of an emergency disconnect.

Pipeline safety protocols and regulations
Newly released Dakota Auditor Version 4.8 includes the new pipeline safety module, additional state regulatory coverage, guidelines from the Organization Resources Counselors regarding management of metal removal fluids, and other updated regulatory information.
The pipeline safety module helps pipeline operators achieve compliance with the reporting requirements and safety standards regulated by the US Department of Transportation (DOT 49 CFR 190-198) for gas pipeline, natural gas, and related facilities. The software contains applicability determinations, compliance protocols, and regulations that cover operations, maintenance, record keeping, and reporting requirements noted by the Research and Special Programs Administration Office of Pipeline Safety.
The software combines a comprehensive, regularly updated information resource with an auditing tool to assist with managing and monitoring regulatory compliance for every site. The software helps you determine regulatory applicability, develop audit protocols, and do regulatory research and management training. It enables users to build a regulatory profile of a facility and produce targeted, customizable checklists that are specifically applicable to individual facilities.
The program, which assures consistency among states, facilities, and auditors, covers federal and state requirements with regular updates, Responsible Care Codes, and ISO 14000.

Aboveground fuel storage container
Fire-Hoppers are designed for low profile, secondarily contained, fire-protected aboveground fuel storage.
The UL-2085 listed unit is a double-wall steel tank with lightweight porous insulating material between the two walls, providing thermal protection to the main tank.
Its domed top design helps prevent rain, snow, and other debris from accumulating on top of the tank. The tank features a small footprint and optional pump and equipment packages.
