	Marine Loading Arms A chain is only as strong as its weakest link. Oil flows safely across the land in pipelines and tanker trucks, and ships are overbuilt to the most exacting standards, but where the oil leaves the land and begins its marine journey there is a vital and exposed link. Marine Loading Arms stand up to fourteen stories high and weigh 10,000 to 140,000 lbs. The systems that control them are very complex, yet must be foolproof, rugged and dependable. J. W .Long & Associates design control systems that meet the most demanding standards for hostile environments and hazardous locations world wide. One design strategy we implement is efficient low power circuits with entity concept approval. This eliminates the need for the multitude of Intrinsic Safety Barriers, or isolation relays normally used. Savings in cost, efficiency and weight ensue and smaller explosion-proof enclosures can be used.   Advanced Ground Vehicle Technology In 1985, under the auspices of FMC, J. W. Long built and maintained a remarkable control system for a remote control vehicle, meeting the criteria of a joint DARPA/Army program. The complete AGVT system comprises a command center, a robotic vehicle and an autonomous navigator. Roles envisioned for the AGVT include: use on the battlefield, use in minefields, chemical warfare sites, hostage situations and environmental accidents. The tests were held on remote terrain in Colorado and Kentucky, and were highly successful. The AGVT performed remarkably well in all areas, including extremely accurate remote control (utilizing three video screens in the command center) and autonomous road edge sensing, allowing fully automatic deployment.
