Experience Excellence by design

Marine Liquid Terminals

For over 48 years Lanier has provided engineering design for marine liquid terminals all across the Gulf South, the inland waterways, Latin and South America and abroad. We are experts in all facets of marine liquid design including crude, LPGs, LNG, renewables, ammonia, etc. Our efforts start with conceptual design and carry through commissioning. We work with the USCG, USACE, and other regulatory agencies on a regular basis and provide a multi-disciplined turn key approach to our clients.

Bulk Terminals/Grain

For over 45 years, we have worked with bulk handling companies to design, maintain, and upgrade their bulk facilities. We are experts in all facets of marine terminal design for grain, other dry bulk products and general cargo. Although we have successfully served clients throughout the U.S. and in numerous other countries, most of our projects have been in the Southeastern U.S., primarily along the Gulf Coast and the industrial waterway corridor feeding this area.

Rail Terminals

Lanier is a well qualified multi-disciplined consulting engineering firm with over 48 years of experience in the Gulf South. With over 100 rail projects to our credit we feel we bring the best experience in marine and rail facility design, owing to our dedicated staff, our track record in being on time and on budget with projects both large and small and by being supportive to our clients so that they want to work with us again and again.

Tank Terminals

Lanier has designed tank terminal facilities for over 25 years including, crude, condensate, and refined product facilities along the Gulf Coast and East Coast. Lanier provides a turn key solution from the conceptual layout to commissioning. We have designed 40 million barrels worth of storage including custody transfer, pumps, storm water, fire suppression and all necessary electrical and instrumentation.

Midstream Mooring

Lanier has provided the engineering for this midstream transfer facilities along the Lower Mississippi River as well as locations around the world. These typically involve utilizing anchor piles and mooring buoys. A common application is for a catamaran midstream grain transfer facility or anchor buoy for the bow line of crude oil tankers secured to river bottom with anchors designed for mooring loads.


For over 25 years Lanier has provided engineering design for LPGs, LNG, and other LHGs as classified by the USCG. Our efforts include regulatory assistance with Water Suitability Assessments, Vessel Traffic Studies and USACE permitting as well as the structural design of the marine infrastructure and dredge design. Working under our partnership, LWI, we also provide passing vessel studies, wave studies and other necessary analyses. We have helped develop many projects along the Gulf Coast and throughout the globe.

Port Facilities

Lanier & Associates is a multi-disciplined engineering firm that specializes in industrial marine and public port projects with civil, structural, mechanical, electrical, instrumentation, and coastal engineers on staff. In addition to our complete array of engineering services, we also perform topographic and hydrographic surveying, construction management, permit acquisition, facility inspections, and wharf design. For over 47 years, we have worked with ports to plan, design, maintain, and upgrade their marine facilities. We are experts in all facets of marine terminal design for public ports, liquid terminals and dry bulk handling facilities.

Shoreline Protection

In the Gulf area, we are all familiar with the damages that hurricanes can cause to shoreline areas. Lanier has worked with several Ports including the Port of Beaumont after Harvey, the Port of Gulfport after Katrina as well as many private entities to help inspect post storm damage to shorelines as well as providing the detailed engineering required to get a shoreline protected to allow for safe utilization of the facility. We work hand in hand with geotechnical companies for these projects and provide the scope of work necessary to perform borings. We provide hydrographic surveys in house to understand the situation including utilizing multi-beam and side scan sonar. We also work with area divers for inspections below water if needed and keep staff on the dive boat during the inspection.

Bulkhead Design

Lanier has designed Shoreline Revetment and Erosion solutions along various waterways along the Gulf South. We have over 40 years of experience in bulkhead design, revetment design, and other options. We work closely with HR Wallingford on the coastal analyses needed for wave action as well as other concerns in the coastal environment. Whether it is installing a new bulkhead or assessing a shoreline failure Lanier can provide the best solution for any given project.
