What are Marine Bumpers And How Do They Assist In Our Offshore operations?

What Are Marine Bumpers?

Marine bumpers are used to prevent ships and other vessels from colliding against each other or against docks, wharves, and piers.


They are made of materials such as foam, rubber, or air-filled within special elastomeric substances. They act like spring storing and releasing energy and are able to cope with the extreme forces under variable conditions. Whether it’s naval vessels, small boats, large docks, or piers; marine bumpers form one of the key marine equipment for safe marine operations.

The port facilities have changed drastically in the past so does the ship with an increase in maritime traffic. Modern ships use fixed marine fenders installed on their hulls. It helps to protect them from hull damage in the event of contact with another ship or berth. Sea piers and docks also utilize dedicated fenders of their own to reduce impact forces at the time of docking.

How Marine Bumpers Are Used for Ship Berthing?

When a ship is to be brought at a negligible speed to the berth, a small increase in speed will give rise to an exponential jump in the momentum. It is the product of mass and velocity.


However, the speed always cannot be reduced to the bare minimum. Due to tides, wind effects, tugs, erratic pulls, engine failures, a good marine bumper can save the day in such exigencies. Ideally, a marine bumper should be cost-effective, with low maintenance cost and high durability.

How Marine Bumpers Are Used for Ship Berthing?

When a ship is to be brought at a negligible speed to the berth, a small increase in speed will give rise to an exponential jump in the momentum. It is the product of mass and velocity. For example, the displacement tonnage of 10,000 when multiplied by a speed of one knot has half the momentum when multiplied by a speed of two knots. The energy of the impact is twice, thrice, four times, and so on with every knot of increase of speed.
However, the speed always cannot be restricted to the bare minimum, owing to certain conditions such as the tides, wind effects, tugs erratic pull, engine failures, etc. A good marine bumper can save the day in such exigencies. Ideally, a marine bumper should be cost-effective, with low maintenance cost and high durability. The material should be locally available should a case of replacement arise.

How do Marine Bumpers assist in our Marine Operations?

Most industries are now required to treat their wastewater on-site before it is discharged to a river or sewer (to meet a discharge consent limit). However, this treatment will vary depending on the contaminants present.

Wastewater treatment is the process of converting wastewater into water that can be discharged back into the environment. During our wastewater treatment for an offshore vessel last week in Guyana, our staff assist to install bumpers during the operation, which help to reduce the impact of contact with the vessel during our project.

How Hooks Play an Important Part in Our Offshore Operations?

How do hooks ensure safety for organizations?

Adopting the hooks enables organizations to put corporate safety policies into practice. It achieves the common goal of reducing risk and improving workplace safety.

Hooks, slings, and other lifting gear should not be loaded beyond their safe working loads. Strops and slings should be of sufficient size and length to enable them to be used safely and be so applied and pulled sufficiently tight to prevent the load or any part of the load from slipping and falling

What type of hooks are available?

Eye Hooks

On an eye hook, a chain or fittings are welded for a permanent connection to the sling. With an eye hook, you get far more flexibility movement, and ergonomics to position the hook and attach it to the load.

Clevis Hooks

A clevis fastener is a fastener system consisting of a clevis and clevis pin. The clevis is a U-shaped piece that has holes at the end of prongs to accept the clevis pin. The clevis pin is like a bolt but is only partially threaded or unthreaded with a cross-hole for a split pin

Swivel Hooks

There are two types of swivel hooks, and the user should be aware of the type of swivel hook that they’re using before lifting a load into the air:

Positioning Swivel Hook – This type of hook swivels to allow the rigger to properly align the hook during connection to the load. This type of hook is NOT designed to rotate while under load and is only to be used when you need to position the hook onto the pick point.

True Swivel Hook with Bearing – This type of swivel hook has a bearing inside that allows the hook to rotate freely under load. Top fitting swivels and pivots to allow the load to rotate to prevent twisting of the rigging.

How clevis hook improves our rigging activity for our recent offshore project?

A clevis hook refers to a hook with a U-shaped attachment point or coupling with holes to thread a pin through and assemble during rigging activity.

Our team of 10 people utilized clevis hook last month to lift a crane radiator for an offshore project in Guyana.  Crane Radiator assists in increasing the capacity of the radiator and dissipating the heat from the engine.

After installing the crane radiator, we released the clevis hook with our certified rope access team.
