The Importance of Marine Inspection Services for Vessel Safety

There is no doubt that regular marine inspections help keep ships of all types and sizes in good working order. This is particularly important for vessels carrying passengers or cargo, such as cruise ships, tugs, and barges.

However, a recent study found that the Coast Guard needs help hiring and training a workforce capable of inspecting U.S.-flagged passenger and cargo ships, offshore drilling units, towing vessels, and barges under the new Subchapter M inspection program.

Inspections

Marine inspection services play an essential role in vessel safety. A thorough inspection is necessary to identify potential risks, whether for a potential charterer to ensure the vessel is suitable for his requirements or an international standardization body confirming compliance with a particular standard.

The Marine Safety and Security branch runs full inspection campaigns in Canada to ensure our shipping sector complies with regulations made under the Canada Shipping Act, 2001 and international conventions. We also inspect all commercial vessels using a risk-based approach regardless of whether they carry an inspection certificate.

In addition, Canada’s Port State Control inspections examine the air emissions from ships to ensure they meet the sulfur and nitrogen oxide limits set out in the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI. These inspections result in detentions if issues are found, so they are essential to watch.

Preventative Maintenance

Regularly scheduled inspections of your systems and equipment can keep them working at optimal efficiency and reliability. Failures detected and corrected before they can save you money in the long run.

It can also help to protect your business from responsibility litigation. If your company is responsible for a piece of equipment that has failed during a voyage, you may pay for repairs and replacements, which can be costly.

The best preventative maintenance plans consider several variables, including historical asset performance and budgets. The team responsible for creating a plan must include leadership.

Safety Measures

A vessel’s safety measures are critical to protecting life and property at sea. Without them, accidents, injuries, and even death can occur.

Vessel inspections are crucial to identifying hazards. They are also important for preventing damage to ship structures and equipment.

During an inspection, surveyors examine the entire vessel’s structure and gear to identify defects. They can then recommend remedial actions to the owner or flag state.

Classification surveyors inspect commercial ships to ensure that they meet requirements set by the government or classification agencies. They also check cargo gear to ensure it complies with regulations.

Remediation

The marine industry is a challenging place to work and can be hazardous for both crew and the environment. Accidents, mishaps and faulty procedures can lead to disastrous consequences.

In the most severe cases, marine accidents can result in the loss of life and total vessel loss. This can be due to structural, explosions, equipment, or machinery failures.

Ship inspections are an essential part of the maritime safety process. They help ensure the structural integrity of ships and offshore structures.

Underwater visual inspections are a cost-effective way to confirm the structural integrity of vessels. They can also assist operators with determining maintenance schedules and workloads best suited to each ship. This helps to avoid dry-docking and minimize downtime costs.

Fire Flow Testing: A Step-By-Step Guide

Firefighting agencies can use water data from hydrant flow tests for training, planning, and marking hydrants. Municipalities also use these data for system planning and design, as well as for the calibration of hydraulic models.

When performing a hydrant flow test, ensure the water flows freely and that at least one alarm device is functioning. That can be a water motor gong or an electrical switch.

Static Pressure

A static pressure gauge is attached to a test hydrant in fire flow testing. It will measure the static water pressure at that hydrant, which measures the normal operating pressure in a water main under distribution-system flow conditions.

The static pressure at the hydrant is a good indicator of how much pressure there will be when flowing a hose line through the hydrant, which will determine the flow rate that the hose line can produce. Friction loss, the resistance that occurs when water moves along the inside wall of a hose, hose line, pipe, or mains, also affects the flow rate.

Static pressure of 30 psi is required to achieve accredited fire hydrant performance. Still, in areas with low pressure, NFPA allows calculations based on residual pressures, which are half the static pressure. This allows a hydrant with a static pressure of 30 psi to be calculated on the basis that pulls the hydrant down to 15 psi, improving its accredited performance.

Residual Pressure

Fire hydrant residual pressure is important when performing a hydrant flow test. It accounts for the water main’s capacity to produce a water flow rate higher or lower than the hydrant’s static and pitot pressures.

Residual pressure is measured in a flow test by taking static and residual pressure readings on a hand-held pitot pressure gauge. Both readings are then recorded at a static/residual hydrant between the flow hydrants and the water supply.

Once you’ve taken the static and pitot pressure readings on the hydrants, you can close the flow hydrant slowly. This will help you get an accurate result.

Pitot Pressure

A pitot pressure gauge is a hand-held device that measures the velocity pressure of a stream of water. These are commonly used in hydrant and pump flow testing.

For a hand-held pitot, choose a unit attached to the test hydrant, hose, or nozzle for quick and easy readings. The unit should be capable of measuring static and residual pressure.

Fire departments and city planners use hydrant flow testing information to design water-based fire protection systems.

Flow Rate

Water flow tests verify the pressure and flow available at fire hydrants in a city’s water distribution system. This information is important for various purposes, including fire protection, assessing sprinkler system design, and hydrant marking.

Performing fire flow tests regularly can detect potential issues in a hydrant’s piping, valves, and connections to the main. These include closed valves, heavy pipe-wall deposits, and other problems that may reduce the water supply’s capacity to fight fires.

The process involves using a pitot gauge and measuring static (non-flowing), residual pressure, and water discharge rate in gallons per minute. This information can then be used to calculate available fire flow.

Many water utilities do not have workflows specifically for hydrant flow testing, so they develop workarounds to handle this process. These workarounds often lead to data silos and inefficient reporting.

 

The 4 Advantages of Upholstery Repair

Whether it’s leather or fabric, furniture upholstery is an important part of the look of your home. It’s also an essential part of the functionality and durability of your furniture. However, sometimes the fabrics in your upholstery fade and lose their original appeal. This can be a big problem if you want to preserve your furniture’s good looks.

Save Your Furniture

The advantages of upholstery repair are numerous and many homeowners consider reupholstering their furniture a cost-effective alternative to buying new pieces. However, choosing the right upholsterer is important and ensures you have the best work done. Often, upholstered chairs and sofas can become worn down over time from using the elements. They can start to look faded, ripped, and split open. Upholstery can also start to smell, especially if you have pets. Regular upholstery cleaning can help remove odors and prevent them from worsening.
