    Who We Are & What We Do

    Woodfield Systems started trading in 1922 and havebeen designing and manufacturing Marine Loading Arms since 1954. We became a wholly ownedsubsidiary of Aker Solutions in 1998.

    Woodfield Systems have been operating from the same site for the past 40years. We enjoy the benefits of an experienced and skilled workforce whooffer a level of expertise unrivalled in the industry. The company is based onthe North Kent coast of England, just 55 miles from London and only 25 milesfrom the Channel Ports.

    We have design engineers, project management team, sales and support staffemployed at our Whitstable site, with a team of service engineers on variousassignments worldwide.

    Our UK workshop facilities are specifically designed for swivel andloading arm manufacture and assembly. In addition to this Aker Solutionshave facilities worldwide where manufacturing can be undertaken locally.

     Areas where we are able to manufacture include India, Malaysia, Qatar , Dubai ,

    USA, China and Eastern Europe.

    Marine Loading Arms 

    Our Marine Loading Arms can be supplied asmanual, lever-hydraulic, electro-hydraulic witheither hardwired or wireless remote control.

    Manually operated arms can be supplied with attachment brackets for thelater addition of hydraulic operations. Operational limiting controls andother warning devices are available as optional extras. Woodfield Arms,although normally fixed in one jetty position, can be mounted on movabletrailers or rail tracks to provide dockside flexibility.

    Several types of quick connect/disconnect couplings are available for thefull range of Loading Arms. An emergency disconnect coupling is alsoavailable as an operator initiated device or as part of a sequence controlled“ shut down” disconnect system.

    Both our ambient and cryogenic swivels are well proven within the industryand fully compliant with OCIMF Design & Construction Specification forMarine Loading Arms. The LNG swivel has also been life cycle tested. Inaddition to being used within our Marine Loading Arms our swivels areused in offshore loading systems by other companies within AkerSolutions.

    Marine Loading Arms

    Key design

    Woodfield Systems Ltd. 

    The most important feature of aMarine Loading Arm is the swivel jo in ts. These are required to becapable of resisting bendingmoments, shearing forces andaxial load combinations whiler e t a i n i n g l o w t o r q u echarac te r is t ics and s imp lemaintenance. There are a total of6 product swivels on a Marine

    Loading Arm.

    Swivel joints allow for movementof the arm in all planes and freelyfollow the motion of the tankerwhen connected. These joints arerequired to carry high loads andmust not allow any productleakage.

    On an LNG Marine Loading Arm the loading arm components mustundergo a cooling process to prevent thermal shock prior to the product’sintroduction.

    To reduce tanker “ turn around” time an optimum cool down procedure wasdeveloped using finite element analysis (FEA) methods to achieve as shorta time as possib le 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 inmulti-track swivels

    • For cryogenic use, the entire swivel unit is stainless steel, whichactually increases in strength at low temperatures. For ambientapplications carbon steel is the preferred material of construction.

    • Seal design used will withstand design operating pressures, vacuumconditions and high flow velocities.

    Marine Loading Arms

    Innovation in design

    Downtime costs money and with tight shipping schedules and complexequipment to be inspected and maintained, reduced downtime is essential. Aker Solut ions-Woodfield’s dr ive to find cost dr iven solutions focussed onone particular area of the loading arm design; the rigid pantograph linksystem. The use of a wire rope system necessitates frequently plannedmaintenance activities and inspection leading to increased downtime of theequipment.

     As a result all Aker Solut ions-Woodf ield Marine Loading Arms are supplied

    with a rigid pantograph link system. This arrangement consists of a rigidlinkage (not wire rope) between the outer arm and secondarycounterbalance weight support member situated behind the pedestal headassembly. This rigid linkage therefore balances the outer armindependently of the inner arm and is maintenance free due to thenon-lubricated bearings.

    Control Systems  

    The design of the control system for the loading

    arm is based on a ‘fail-safe’ principle wherein anyfailure such as electrical power failure willautomatically put the loading arm into thehydraulic ‘freewheel’ mode.

    Woodfield Systems Ltd. 

    When connected the arm will alwayssafely follow the tanker’s movementsthroughout the working envelope anddrift ranges. The principle of the

    system is based on using handheldtrailing lead or radio control pendantwhich can be operated from the jetty ortanker deck.

    Our supply includes:

    • Jetty control panel/desk 

    • Logic panel 

    Local/remote selector switch

    •  Alarm moni toring equipment

    Direct-on-line motor starter will besupplied on the berth to include thefollowing:

    • Isolator switch

    • Overload protection on each


    • Start pushbutton

    • Stop pushbutton

    • Terminals for remote 'start' and'stop'

    In addition to the above we can alsosupply a more simplif ied lever

    hydraulic control system if required.
