Crane Safety Requires Precision Measurements Ship to Shore

Maritime companies include businesses and governments that develop and utilize hardware to support shipyards, marine terminals, cargo and trade support, exploration and defense, fishing, aquaculture, seafood processing, commercial diving, energy infrastructure and platforms, along with marine transportation. There are multiple categories of maritime companies, including those that build ships, provide maintenance, and oversee logistics for moving an estimated 11 billion tons of goods every year.

A subset of these maritime companies operates vessels and equipment that are responsible for the transport of people and cargo. It is estimated that in the United States, maritime companies employ over 400,000 workers. They are responsible for operating, transporting, moving, and transferring equipment and materials. There is a heavy reliance on reliable cargo cranes and lifting equipment to assist workers in these functions.

Due to the nature of work, safety and regulation are key to maintaining core operations for any type of maritime transport. The work performed on the vessels, as well as on dock, rely on heavy-duty equipment that utilizes accurate measurement for performance, weighing, monitoring, and reporting. Fundamental is the durability of the sensor equipment to withstand unpredictable environmental conditions. Quality, ruggedized equipment that is durable is vital in the operations that utilize waterways to transport goods port to port. This is where Interface plays a vital role as a supplier of measurement and weighing solutions that are designed for maritime use.

One of the most common use cases for Interface Maritime solutions is in the design and operational use of cranes. Cargo handling and crane operations are considered to be one of the most dangerous maritime jobs. The unpredictable nature of onshore and offshore environments requires crane operators to function with precise and accurate measurements throughout all procedures.

Sensors and instrumentation must be able to withstand the various exposures related to maritime work, while meeting the demanding schedules for heavy lifting, as well as moving single and multiple cargo containers at a time. In these types of maritime operations, speed is also an advantage for loading and unloading vessels. Considerations of weight of the cargo and environmental condition monitoring require accurate measurement.

Crane Capacity Verification and Block Safety Monitoring

As demonstrated in the Crane Capacity Verification Application and Crane Block Safety Check Application a customer requires a system to detect if their crane block can lift heavy loads securely, in order to keep working conditions and personnel safe at docks and other maritime transportation applications. If lifting capacities are exceeded, the customer wants a system to alarm them in real-time.


Interface products are ideal for use in heavy equipment that the maritime industry relies upon for a wide variety of equipment used to push, pull, lift, release, contain, and move things in water and on land. Wireless and environmentally protected submersible solutions are standard fare for this industry. Interface load cells, torque transducers, load pins, load shackles and tension links, as well as DAQ and instrumentation solutions provide accurate force and torque data to monitor and confirm the design and in-action processes.  To keep your instrumentation protected, inquire about our Interface Enclosures.

Announcing the Launch of the Interface Pressure Compensated Downhole Load Cell

Interface is excited to announce the release of a new downhole solution for the energy industry, the Interface Pressure Compensated Downhole Load Cell (IPCD).

The IPCD is a Wheatstone bridge foil-gaged-based force measurement solution using proprietary compensation methods and designed to provide highly accurate force data in harsh environments, like those found in the oil and gas industry, while requiring limited maintenance compared to similar solutions on the market. This is a product line that is many years in the making, as we’ve offered it as a custom solution. In fact, it has been developed across multiple applications to meet the needs of the oil and gas industry.

Interface’s new IPCD product is best suited for tension head applications of wireline services, particularly useful in deviated or horizontal wells where topside measurements are no longer reliable. Many applications include conveyance, pump down, perforating, tractor, and high pressure high temperature deep offshore use.

The key benefit the IPCD provides over existing solutions, commonly referred to as “wet” load cells, is its method of compensation. Wet load cells have a hydraulic compensation mechanism that uses pistons and seals, requiring frequent maintenance. Hydraulic compensation is complex for smaller tool providers and performance was suboptimal. For the IPCD, Interface developed a proprietary technology that compensates for that pressure influence and allows for bridge isolation. This means that the IPCD is far more rugged, needing little to no repairs, and it can be used downhole without risk of damage, a first of its kind in the industry.

It provides accurate measurement of downhole tension conditions in both vertical and horizontal wells and the proprietary internal compensation actively measures only the portion of the load caused by axial force, ignoring the portion of the load caused by pressure. Since it is an inherently passive system with no active pressure measurement being made or using a separate transducer, it is a completely analog solution for reliability and temperature stability.

We also test the IPCD heavily before it leaves our doors. The oil and gas industry can be extremely volatile, so we understand that our load cells need to be at peak performance for every use. Each load cell is tested individually on force, creep, temperature and pressure.

Advantages of the new proprietary Interface Pressure Compensated Downhole Load Cell include:

  • IPCD is a standard product from Interface and available today
  • IPCD offers maintenance-free service with significant long-term payback by eliminating disassembly, downtime, calibration, and instrumentation configuration
  • Interface’s new product is a precision with unmatched performance
  • IPCD has minimal thermal and pressure error, combined with world class linearity and hysteresis
  • It has field proven reliability and was designed based on a decades of engineering and force measurement experience

To learn more about the IPCD, we recently published a white paper that goes deeper into how the unit works, the specifications of the solution, as well as providing additional information on our testing process. You can read more about the IPCD in our new technical overview, Interface Pressure Compensated Downhole Load Cell White Paper available online for download.

We also issued a press release announcing the launch of IPCD.

This new product launch is a collaborative effort involving many of our team members in engineering, production and sales.

Check out a few of our applications notes to see how these products can be used for testing in the maritime industry:

Hydrofoil Testing in a Wave Tank

Hydrofoil design for watercraft is a delicate balance between performance and complexity. Finding the right shape without using overly complex angles to achieve the desired amount of lift is crucial when designing a successful hydrofoil. Once an engineer’s concepts are ready for testing, using the best force measurement equipment is required to sense the subtle differences between hydrofoil designs. Lift and drag are the most important characteristics of a hydrofoil. The Interface Model 3A120 3-Axis Load Cell is needed to read these forces. The Fz senses lift and the Fx and Fy sense the drag. Using a model BSC4D-USB bridge amplifier increases the visibility of the load cells output signals. When using the load cell and bridge amplifier, the engineers can record the real-world lift and drag forces the hydrofoils are having on the watercraft. This data allows a more in-depth comparison of proposed hydrofoil designs to find the best model for the job. Learn more.

Mooring Line Tension Testing 

Due to the changing weather conditions, mooring cable lines undergo wear and tear. Users want to ensure all mooring lines for ships or vessels are securely docked at the same loading tension so that they do not risk the mooring lines to break or cause damage. Interface WTSLTL Lightweight Wireless Tension Link can be attached to each mooring cable in use. Results are sent to the customers through the WTS-BS-4 USB Industrial Base Station when connected to the customer’s supplied PC computer or laptop. Data can also be transmitted to the WTS-BS-1-HA Handheld Display for Multiple Transmitters, giving the customer the option to view multiple mooring cable line tensions.
