Who We Are & What We Do

Woodfield Systems is one of the worlds leading manufacturers of Marine Loading Arms with over 50 years experience. The Company was privately owned until 1998 and is now part of MacGregor. MacGregor is part of Cargotec. Woodfield Systems manufactures Marine Loading Arms capable of transferring a range of products including crude oil, refined products, petroleum gas and LNG with operating temperatures of between –164°C to +200°C. Originally based in Rochester, Kent, Woodfield Systems moved to its present site in Whitstable in 1969. This site is on the North Kent coast of England just 55 miles from London and 25 miles from the Channel Ports and is the location of the main office and manufacturing facility. We have design engineers, project management, sales, support staff and a team of skilled and qualified service engineers who offer a level of expertise unrivalled in the industry.

Our facility is specifically designed for loading arm and swivel manufacture and assembly. In addition to this MacGregor have facilities worldwide where manufacturing can be undertaken.


Marine Loading Arms

Our Marine Loading Arms can be operated as manual, lever-hydraulic or electro-hydraulic with either hardwired or wireless remote control. Manually operated arms can be supplied with attachment brackets for the later addition of hydraulic operations. Position monitoring and other warning devices are available as optional extras. Woodfield Arms, although normally fixed in one jetty position, can be mounted on movable trailers or rail tracks to provide dockside flexibility.

Several types of quick connect/disconnect couplings are available for the full range of Loading Arms. An emergency disconnect coupling is also available as part of a sequence controlled “shut down” disconnect system.

Our ambient and cryogenic swivels are well proven within the industry and are fully compliant with the OCIMF Design & Construction Specification for Marine Loading Arms. The LNG swivel has also been life cycle tested. In addition to being used within our Marine Loading Arms the swivels are also used in offshore loading systems.


Marine Loading Arms

Woodfield Marine Loading Arms range from 4” to 24” dia. and are designed for transferring crude oil, refined products, slurries, chemicals, LPG, Ethylene and LNG. The equipment can cover operating temperatures from -164ºC to +200ºC.

Marine Loading Arms

Key design


The most important feature of a Marine Loading Arm is the swivel joints. These are required to be capable of resisting bending moments, shearing forces and axial load combinations while retaining low torque characteristics and simple maintenance. There are a total of 6 product swivels on a Marine Loading Arm. Swivel joints allow for movement of the arm in all planes and freely follow the motion of the tanker when connected. These joints are required to carry high loads and must not allow any product leakage.

On an LNG Marine Loading Arm the loading arm components must undergo a cooling process to prevent thermal shock prior to the product’s introduction. To reduce tanker “turn around” time an optimum cool down procedure was developed using finite element analysis (FEA) methods to achieve as short a time as possible without causing any overstressing. Specific features of WSL Swivels are: Single track allows for accurate calculation of bearing capacity and is

not subject to problems of machining tolerances as experienced in multi-track swivels

For cryogenic use the entire swivel unit is stainless steel which actually

increases in strength at low temperatures. For ambient applications carbon steel is the preferred material of construction.

Seal design will withstand design operating pressures, vacuum

conditions and high flow velocities.

Marine Loading Arms

Innovation in design Downtime costs money and with tight shipping schedules and complex equipment to be inspected and maintained reduced downtime is essential. Woodfield Systems drive to find cost driven solutions focused on one particular area of the loading arm design; the rigid pantograph link. The alternative wire rope system necessitates frequent planned maintenance and inspection leading to increased downtime of the equipment. As a result all Woodfield Marine Loading Arms are fitted with a rigid pantograph link (no wire rope) between the outer arm and secondary counterweight arm situated behind the pedestal head assembly. The rigid link therefore balances the outer arm independently of the inner arm and is maintenance free due to the non-lubricated bearings.

Rigid pantograph link


Marine Loading Arms - MK9S

The Woodfield LNG Marine Loading Arm is specifically designed for the transfer of liquefied natural gas (LNG). The loading arm features a structurally supported product pipe to cope with the cryogenic properties of the liquid.


Marine Loading Arms - MK9

The Woodfield MK9 Marine Loading Arm is designed for general purpose service with additional strength and support for the use of emergency release systems and other similar applications.


Marine Loading Arms - MK6

The Woodfield MK6 Marine Loading Arm is designed for lightweight service where emergency release systems and other similar applications are not required.


Marine Loading Arms - ACW

The Woodfield ACW Marine Loading Arm is designed for manual operation for lightweight ambient service where emergency release systems and other similar applications are not required. Typically it is suitable for barge loading and other small ocean going vessels.


Emergency Release Systems (ERS)

We can supply ERS for Marine Loading Arms to incorporate the following features:-


Fire safe ball valves to API 607 1993 4th edition

Ball valves designed to minimise

spillage on release Ball valves mechanically

interlocked to ensure simultaneous separation during an emergency release

Ball valve closure time which can

be adjusted between 5-15 seconds with flow regulators located in the hydraulic control cabinet

Mechanical/hydraulic interlock

valve which prevents disconnection before ball valves are fully closed

Emergency release coupling

which incorporates a stored energy feature to ensure clean separation

Emergency release coupling which

has a shear pin to avoid accidental release

An over centre mechanical lock

which also prevents accidental release

Emergency release coupling which

will remain clamped in the event of hydraulic or electrical power failure

Quick Connect / Disconnect Couplers (QC/DC) We can supply QC/DC for Marine Loading Arms to incorporate the following features:-


Manual or hydraulic operation Lubrication of all moving parts

without dismantling the coupler Coupler clamps which are designed

to work simultaneously Mechanism designed to exert even

pressure on the tanker manifold thereby avoiding overstressing of the flange

An over centre mechanical lock to

prevent accidental release External guides for correct

alignment to the tanker manifold Coupler which remains clamped in

the event of hydraulic or electrical power failure

Portable hand pump supplied for

manual release in the event of hydraulic or electrical power failure

Coupler strength based on the

OCIMF Snap connectors to hydraulic lines

to ensure no leakage of hydraulic oil when fitted with emergency release system

Control Systems

The design of the control system for the loading arm is based on a ‘fail-safe’ principle where any failure such as electrical power will automatically put the loading arm into the hydraulic ‘freewheel’ mode.


When connected the arm will always safely follow the tanker’s movement throughout the working envelope. The principle of the system is based on using handheld trailing lead or radio control pendant which can be operated from the jetty or tanker deck.

Our supply includes:-

Jetty control panel/desk

Logic panel

Local/remote selector switch

Alarm monitoring equipment

Direct-on-line motor starter will be supplied on the berth to include the following:-

Isolator switch

Overload protection on each phase

Start pushbutton
