Barges are indispensable in many industries for storage and transportation of equipment and materials and for use as work platforms on water. Barge accidents involving injury to crew members and damage to property are not uncommon, but they can be prevented in many cases with the correct safety protocols in place. The United States Coast Guard (USCB) has some particular suggestions for maintaining safety on barges. Below are some recommendations based on their safety advice for those working on barges:

INSPECTIONS

• If they don't have current ABS classification, barges should be thoroughly inspected annually by a USCG official or an experienced marine surveyor with accreditation from the Society of Accredited Marine Surveyors (SAMS) or National Association of Marine Surveyors (NAMS).
• Annual inspections should, minimally, assess overall structural conditions of a barge. Beyond this, they should also be specific to the particular type of barge, i.e. spud barge, deck barge, sectional barge, etc. and specific to the particular type of equipment used on the barge.
• All equipment used on a barge should be inspected on a regular basis as recommended by the equipment’s manufacturer.
• All materials should be stored securely at all times, and barges should be inspected on a regular basis to ensure that materials are in their proper places.
• Results of inspections should be carefully documented, and inspection reports should be stored in an established location onboard a barge for crew members to reference if needed.
• If a barge is deemed unsafe or not in proper working order during an inspection, it should be taken out of commission and not used until all safety issues are properly addressed and all necessary repairs are made.
• If any equipment on a barge is deemed unsafe or in need of repair, it should be promptly removed from the barge until it passes further inspections.
• Before a barge is filled or emptied, it should be inspected for leaks.

PREPAREDNESS

• Barge decks should be organized well, and all equipment and materials not in use should be stored properly.
• Employees should be informed of where all safety equipment is on the barge. Safety equipment stock checks should be performed regularly to ensure that all necessary equipment is available to crew members. If safety equipment is damaged, it should promptly be replaced with new equipment.
• Employees should be well-aware of the locations of all openings and hatches on deck.
• A disaster preparedness plan should be in place so there is a protocol to minimize harm to workers and property in the event of a hurricane, tropical storm, flood, or other weather event.
• As a part of disaster preparedness, employees should be well aware of the conditions in which a barge must be relocated to a more protected area based on tide/river gauge readings. If a barge is not self-propelled, a plan should be in place to move it using a self-propelled vessel like a tug boat or pull boat.
• If a barge is not self-propelled, it’s a good idea to always have a pull boat, tug boat, or similar boat in the area should the barge have to suddenly be relocated.
• All crew members should complete required safety trainings on a regular basis that cover both barge safety and safety regarding the specific duties of their positions.

As we mentioned, there are some safety concerns that are specific to the type of barge or the type of equipment being used. This list doesn’t cover all the bases of barge safety, but it covers many of the important ones. Remember that an ounce of prevention is worth a pound of cure in terms of keeping workers safe and that training and inspections can ultimately save you a lot of trouble.

A seawall is a protective structure or embankment used in a coastal area to help mitigate damage and disturbance associated with waves, tides, tsunamis, hurricanes, and other natural disasters. Sea walls protect from overtopping waves and storm surges. They help coastal areas retain soil that would otherwise be lost or disturbed over time, ultimately preventing land from sliding. And they keep real estate and commercial properties as well as other coastal resources safe from water damage.

SEAWALL VS. BULKHEAD

You may have heard of seawalls referred to as bulkheads and vice versa, but true sea walls differ from true bulkheads in that they provide shelter from waves as well as retaining soil in an area. A bulkhead, on the other hand, primarily serves the purpose of providing stabilization at the shoreline in order to retain soil. Both seawalls and bulkheads help stop the land from sliding due to their soil retention capabilities, but seawalls are bigger and serve the dual purpose of interrupting waves and surges. Seawalls are frequently constructed using concrete, while bulkheads may be constructed using gravity structures or sheet piling.

MATERIALS

As mentioned, seawalls can be made of concrete, but they are also quite often made of steel. Many are made of concrete with steel reinforcements. They can also be constructed of timber, boulders, vinyl, or composites. Vinyl seawalls are a popular option when a seawall needs to be constructed easily and quickly, but they need to be replaced every 20 years or so. Wooden seawalls are an attractive choice, but they are the most easily damaged of all types. When seawalls are constructed, they can have seaward faces that are concave, vertical, or stepped. They are commonly built with defensive materials referred to as revetments, which are laid on their slopes. Additionally, they may include quays and landing platforms for unloading and loading vessels. They may also be engineered with jetties, groins, and offshore breakwater.

STEEL AND VINYL SHEET PILE

When constructed with steel, seawalls are often comprised steel sheet pile. Steel sheet pile is a great option for seawall construction because of their relative ease of installation, strength, and longevity. Although they can acquire damage and erosion from years of saltwater wear and tear, steel sheet pile is relatively long-lasting. Additionally, when steel sheet piles are not utilized, vinyl sheet piles are a great alternative. While vinyl sheet piles do not carry the same strength as steel sheet piles, vinyl sheets are less susceptible to corrosion than steel.Engineering specs will differ based on the requirements of the particular area where a seawall is installed. Soil properties, topography conditions such as grading and elevation, embedment, and water levels should all be carefully assessed during the design process to ensure a high-quality build. Zoning restrictions as well as local ordinances must be considered in the construction process.The frequency and scope of maintenance and repair after a seawall is constructed will differ based on the materials used in construction as well as coastal conditions, i.e. how many storms occur in a particular area at any given time. Seawalls that are failing can pose significant risk to coastal properties and other resources. Seawalls that do not adequately do their jobs may have erosion holes, settling soil, or long cracks that present issues. These vulnerabilities should be promptly addressed through repair or replacement of damaged seawalls.

EQUIPMENT

Types of equipment used in seawall construction include excavators to prepare an area for installation and for backfilling, pile driving equipment if piles are to be installed, barges for storage of equipment and materials, cranes, tiebacks, anchors, welding equipment, and other specialized equipment, depending on the particular seawall construction project.In some areas where construction of a new seawall is being proposed, the pros and cons of construction must be carefully weighed. Seawalls do a lot of good, but they can also harden shorelines on coastal ecosystems and can otherwise disrupt the natural coastal exchange of sediment. This can result in damage to intertidal beaches and wetlands. Sea walls can also contribute to the dissipation of beaches due to how they modify the transport of sediments. If the need to protect an area from natural disasters and erosion is critical, though, a sea wall is a very viable choice.

In marine construction, the creation of deep foundations is often necessary to ensure that structures are properly supported. This is especially the case in areas where the surface level of the floor of a lake or an ocean isn’t strong enough to provide support to heavy loads. Pile driving is used as a way to engineer a deep foundation. Piles are driven several feet below the surface of the floor or ground to help create rock-like, sturdy platforms.Sheet piles are often made of steel, concrete, or timber. Composite sheet piles are made of a mixture of concrete and steel. This type of pile can be used to create capped columns or to build wall-like foundations underground. Sheet piles either have to be forcefully driven into the ground, or they are driven into holes that are drilled prior to their placement. The depth of a foundation created using the driving of sheet piles is determined by how far below it takes to reach stable, solid ground.In addition to sheet piling, structural pipe piling is often used in areas of marine construction. Pipe piling creates a tremendous amount of frictional load resistance in deep foundations and boasts excellent point bearing capabilities.

Materials Used in Pile Driving for Marine Construction

• Sheet pile (steel, concrete, timber, composite, or other types)
• Steel beams
• Pipe piles
• H-piles*
• Wide flange beams

*An H-pile differs from a wide flange beam because its flanges are as deep as they are wide, and its flange and its web have the same amount of thickness. It’s made up of three connected square components that form the shape of an “H.” This “H” design offers added weight distribution and ultimately greater support for many bigger and weightier structures. H-piles are very useful in dense soils and in rocky areas.

Equipment Used in Pile Driving for Marine Construction

• Piling hammers (hydraulic hammers, drop hammers, air/steam hammers, diesel hammers, etc.)
• Piling winches, which are hand-controlled, high-speed winches that help hoist piles up and down
• Piling rigs mounted on pontoons or barges
• Hanging leaders (hanged from the jib of a crane)
• Deck, sectional, or similar functioning barges for safe use of piling equipment

As mentioned, pile driving plays an important role in marine construction, especially in areas like bridge construction and cofferdam construction. Below is some information about how pile driving contributes in these arenas:

Bridge Construction

For bridge construction, pile driving is employed where scour protection is needed or where other foundation materials won’t provide adequate support for direct bearing footings. Steel beams (h-piles and wide flange beams) or concrete sheet piles are common in the building of bridges. The type of hammer used to drive piles for bridge applications is most often one with the heaviest amount of ram that can be applied without damage to the pile itself. Hydraulic, air/steam, gravity, and diesel hammers are common.

Building Cofferdams

A cofferdam is a temporary enclosure built within a body of water that allows water to be pumped out of the area to create a dry surface on which to build. Pile driving is instrumental in the creation of cofferdams. Typically, sheet piles and pipe piles are driven during the construction of a cofferdam. Sheet piles, along with a steel bracing system, help create the overall structure of the cofferdam. Pipe piles are essential to the successful construction of a cofferdam’s foundation, and they are ordinarily driven using hydraulic hammers or diesel hammers, unless another type of hammer is better suited to the project.In addition to being useful in cofferdam and bridge construction, pile driving is also widely employed in the construction of marinas, harbors, quay walls, bulkheads, and wharfs. Wherever a stronger foundation is needed, pile driving can be of service.

A push boat, sometimes called a “pusher” or “pusher boat,” is a type of boat engineered for pushing large vessels like barges as well as oil rigs. As opposed to a tug boat, a push boat only pushes, while a tug boat pulls a larger vessel to get it from point A to point B. While push boats are typically used in inland areas, they are also sometimes used in ocean areas. Below is some information about what differentiates inland push boats from ocean push boats.

Inland Push Boats

These are by far the most common kind of push boats. They are employed in river areas, canals, and other inland waterways. Inland push boats typically have a shallow draft, square bow, large plates mounted to their bow to aid in pushing, and knees. They also have flat sterns that help boost their pushing capabilities. Their horsepower output ranges from between around 600 hp to 10,000 hp, with most inland push boats clocking in with horsepower around 1,200 hp. In terms of size, most push boats are between 30 to 250 feet in length and 20 to 60 feet wide. Some larger inland tug boats designed for long hauls offer living quarters and work space for crew members.

Ocean Push Boats

It’s more rare for a push boat to be “ocean-going,” meaning that it is used to haul barges long distances across turbulent ocean waters. This type of task is best handled by an ocean-going tug boat. If you hear a boat referred to as an ocean push boat, it is most likely either meant for use in ocean harbors or for use in coastal or intracoastal waterways. Ocean push boats can perform varied jobs in port, harbor, and coastal areas. Push boats used in harbor areas may be a bit smaller than push boats used in other areas to allow for easier maneuvering. If a push boat is used in the ocean, its exterior is usually treated in a manner that helps prevent corrosion from salt water.Ocean Push Boats vs. Tug BoatsSome push boats are used in offshore construction to move barges and other vessels limited distances or to aid in maneuvering them to meet project needs. As mentioned, tug boats are a better fit for jobs that require moves of extensive distance on the open sea. Ocean-going tug boats are larger in size than push boats and offer more horsepower generally. They are specifically engineered for extensive use in the ocean and to handle turbulence on the water. They often make use of large propellers to increase their towing capabilities. Additionally, they have longitudinal bulkheads, welded-steel hulls, and high lift rudders to enhance their long-distance towing capabilities.

SIMILARITIES

In many ways, there are more similarities than differences between inland push boats and ocean push boats. They both perform similar jobs, and oftentimes a push boat that has been used in inland areas can later be used in ocean areas and vice versa. Many newer push boats, whether inland or ocean, may be truckable too, which means that they can be transported on the road as well as on the water to get them to your project more efficiently. Before you invest in any particular kind of push boat, make sure you know enough about its specs to give you peace of mind that it will be able to handle your towing jobs. If you are buying a used push boat, make sure you also are aware of its history, including any major repairs as well as where and how it’s been used.
