The fore and aft rakes are designed to give a reasonable towing speed and sea-keeping ability within the constraint of maximizing the barges’ carrying capacity. Box walls are vertical structures that are tied into the deck edge of the main deck while allowing maximum cargo deck area while allowing reasonable walkways down each side. Roger Nite continues his nearly 40 year long engineering journey by leading the firm's projects for building heating, ventilation, conditioning, monitor/controls and water management systems. Responsible for the administration of all projects big or small with an extensive background in specialized facilities, new construction, modernization, renovation, sustainable designs and more. We are committed to providing customized and innovative MEP designs that meet the unique needs of our clients. We understand the importance of reliable and efficient MEP systems applications for numerous building types.

Growth
Los Angeles, with resources to effectively serve construction projects up and down the great state of California. Engineering feasibility studies-evaluating existing structures for proposed additions or change of use. Working with top Architects, Civil & Structural Engineers, together utilizing the best of today's technology to further enhance a building's sustainability, comfort, value & safety. We are truly an employee-owned company, where employees at any level in the company may purchase stock, if available.
Economic Development
A good number of years ago damage immediately aft of the forward and aft rake radii was noticed in older wood-chip barges. The latest designs on all sizes of barges with scow bows has been completed with increased radii both fore and aft eliminating separation and cavitation and giving a marginal increase in loaded towing speeds. Traditionally, side shell fendering such as 10” x 10” wood strips, face-in angles or half pipe added longitudinally to the side shell have been applied to provide suitable fendering. Time has shown that these devices rot or crack and allow seawater to collect against the side shell plating inevitably leading to corrosion and eventually serious leaking.
Locations
Yet a further development of this class of barge is the very specialized submersible barge capable of lifting oilrigs, dredges, and other awkward floating structures for long distance ocean transits. Oil and chemical barges are complex and are the exception in that they carry their cargoes below deck and they generally provide their own pumping system. As of this year, all oil barges are to be double-hulled which has led to a major new building program over the last ten (10) years. This midship section illustrates how the double hull is installed with the double bottom sloped to aid in drainage to a sump where the suction pipe is located. Probably the most numerous of all the barge types is the simple hopper barge designed to carry bulk cargoes in open hatches. These barges are definitely only for river or harbour work as due to their lack of longitudinal strength they would simply fold up in a seaway.
If you're looking for a collaborative environment, growth, and the opportunity to make an impact, we want you on our team. Bob Higgins has been with the firm since 1996 when he started as an intern following graduation from the School of Engineering at Vanderbilt University with a degree in Civil Engineering. As can be imagined, developments in barge designing come slowly, but there have been a number of them. They range from the simple punt to the very specialized heavy lift ocean going barges. In very general terms, a barge is a sealed vessel of very full form and a simple rectangular shape.
Wood sheathing, asphalt, and even concrete have been tried to strengthen the decks of existing barges but all have proven to be only stopgap measures. The length to breadth ratio of four-to-one and a breadth to depth ratio of again four-to-one have been proven, over time, to give a good barge design and is a good place to begin with a new design. The barge berth has two fixed harbor cranes, with the 10-hectare yard complemented by two reach stackers and three internal transfer vehicles. New barge terminal will be operated by ATI-subsidiary Tanza Container Terminal Incorporated and will enable greater connectivity by sea within the Philippines.
Heavier bottom plating, coupled with intermediate transverse frames, satisfactorily strengthen these areas. This large deck barge capsized when a cargo of lime rock became water logged and subjected the barge to the Naval Architects nemesis of free surface effect. She rolled over onto the offloading dock doing much damage to her main deck and opening up 13 of her 21 compartments. As we saw on the last illustration, the barge is afloat on the air bubbles in her void spaces.
Her back was broken and her bottom plating ripped to shreds but after all this she did survive to sail again. This unusual photo shows the two vessel halves being towed to Esquimalt Graving Dock for eventual repairs and reattachment. In the face of ongoing road congestion issues, Tanza Barge Terminal offers cargo owners a more efficient and sustainable alternative to trucking. With its container yard, causeway, berth, jetty, breakwater, and deck facilities, the barge terminal is projected to save around 150,000 truck trips yearly. Since 1955, Barge has been carefully, thoughtfully designing solutions for clients across the public and private sector.
Building Systems Engineering and Consulting Services
Like us, barges come in all shapes and sizes and work at many different purposes.

Barges can take an enormous amount of damage and still survive although this one has probably seen the last of her days. This large log barge broke free from its towing tug and was found draped across Edward King Island on the west coast of Vancouver Island.
During the design period, very special attention is given to designing the main deck so as to give the vessel the maximum required deck strength. On scow-bowed barges, damage that was noted on older barges has now directed attention to the slamming areas forward, immediately aft of the forward rake. This damage can occur when towing empty barges in a seaway noting that coastal barges are rarely fitted with ballast tanks.
Newer barges have now eliminated these appendages and by increasing the side shell plating thickness over the wind and weather areas of side deck and shear strake, have effectively eliminated the need for fendering. Skegs are appendages added within the aft rake to give the barge directional stability. Skegs have traditionally been either canted plates or banana-shaped appendages added to the aft rake to create drag (or parachute) effect. The latest designs now utilize side shell skegs, whereby the side shell plating is extended right to the stern, which has been found to give greatly improved directional stability coupled with reduced drag.
Barge Design does not accept unsolicited resumes from recruiters, headhunters, contract recruiters, search firms, or employment agencies. Before any payment obligation for a referral or recruiter fee can be established, a Barge placement agency services agreement must be in place. Any unsolicited resume or candidate contact information, including those sent directly to Barge hiring managers or any other employee, will be deemed the property of Barge upon receipt.
A most interesting variation on the hopper barge is the split hopper barge designed to transfer waste material, or spoil, out to a dumping ground. The two halves of the hull are hinged and held together via a pair of hydraulic rams. New deck designs consist of heavy deck plate of 16, 19, or even 24mm in thickness combined with heavier longitudinals in the 170 x 125 x 12 mm range. It has been found that deck longitudinals fail under impact or excessive loading by tripping (illustration) which then allows the deck plating to dish giving, in time, the main deck to take up a starved dog look. An effective answer to this failure is to add carlins of 150 x 10mm flat-bar plating transversely at the half span of the longitudinal. We are an engineering and architecture firm with diverse in-house multidisciplinary practice areas.
This partnership has resulted in the modernization of the Batangas Port as a fully integrated port gateway and the continued optimization of operations at Manila South Harbor. The latest partnership in Cavite leverages DP World’s experience in building supply chain networks globally and ATI’s local port operations capabilities. Finally, a most interesting development in barge design has been the progress in introduction of the Articulated Tug and Barge, or ATB, combinations into coastal and open water transportation .
