Fender Davits Suppliers

A 3300 by 6500 pneumatic Yokohama-type fender weighs about 3.8 tonnes dry and noticeably more once it has been pulled out of the water; nobody on a tanker's main deck wrestles that into a stowage cradle by hand. The davit does. Fender davit suppliers carry the hydraulic, electric, and manual deck cranes designed specifically to lift, slew, and stow pneumatic and foam-filled fenders during ship-to-ship transfer, FPSO offloading, and conventional berthing. The right davit specification keeps the operation single-operator, repeatable, and well inside the lifting standards a class surveyor will eventually inspect.

What a Fender Davit Actually Does

A fender davit has one job: move a heavy, awkward fender between its working position alongside the hull and its stowed position on deck. That sounds simple until the fender is 4 to 8 tonnes wet, the deck team is on a moving vessel, and the operation has to happen in a confined slot between the mooring deck and the side rail. Davits in this segment typically cover safe working loads from 1 to 10 tonnes, with reach over the side sized to the fender diameter and the freeboard at the deployment point. Integrated stowage cradles, swivel hooks, and quick-release end fittings turn what would otherwise be a multi-person rigging exercise into a single-operator procedure.

Davit Types and Drive Configurations

The market splits across a small number of configurations procurement officers are typically shortlisting against:

• Slewing davits with a fixed pedestal and rotating boom for standard deck installations.
• Knuckle-boom davits with a hinged outer section, used where reach has to fold inboard for stowage clearance.
• Telescoping davits for vessels with limited deck footprint or variable reach requirements.
• Drive options covering manual hand-pump units for small workboat fenders, electric for medium ranges, and hydraulic power pack drive for the heavy STS davits at the top of the load range.
• Stowage and accessories including integrated cradles, swivel hooks, quick-release shackles, and overload protection.

Sizing for the Fender on Deck

Davit specification follows the fender, not the other way around. A 3300 by 6500 pneumatic Yokohama-type weighs roughly 3.8t dry and several hundred kilos more saturated; a smaller 2000 by 3500 unit is well under 1t. Reach over the side has to clear the maximum hull beam at the fender contact point, slew angle has to land the fender squarely in its cradle, and the davit base has to sit on deck plate stiff enough to carry the dynamic load. Established vendors model the case against the actual fender on the actual vessel rather than picking the nearest catalogue size, and they account for ice, list, and vessel motion where the operation calls for it.

Class Approval and Lifting Standards

Fender davits are lifting appliances under class society oversight, and the certificate package matters as much as the steel. Reference standards include DNV 2.7-1 for offshore lifting appliances, EN 13852-1 for offshore cranes, and EN 14492 where winches are involved. Class type approval from DNV, ABS, Lloyd's Register, Bureau Veritas, RINA, or ClassNK should be available at quotation rather than promised after the fact, and proof-load testing certificates need to ship with the unit alongside the EN 10204 3.1 material certificates for the structural members. Periodic load tests during the davit's working life follow the same paperwork trail.

Brand Coverage and OEM vs Distributor Sourcing

Palfinger is the most visible OEM in this market and appears as the brand listing on multiple vetted suppliers; the rest of the segment is covered by TTS, MacGregor, Heila, Vest, and Effer across different load ranges and drive types. The OEM versus authorised distributor distinction matters more than it does for commodity gear, because warranty support, type-approved spares, and proof-load test traceability all flow through the manufacturer's channel. Davits typically ship as part of a broader fender deployment package, and procurement teams often source through the same vetted marine fender suppliers that hold the matching pneumatic and foam-filled equipment for the same vessel.

Installation, Retrofit, and Commissioning

Newbuild davit specification goes through the shipyard with the rest of the deck outfit, but most of the real activity in this segment is retrofit on operating vessels facing a new STS contract or upgrading to larger fenders for a different trade. Retrofit work covers deck plate reinforcement to carry the davit base load, hydraulic power pack integration with existing services, control interface routing, and commissioning with a site acceptance test and proof-load test attended by class. For the STS operations the davit will support day to day, experienced STS service providers coordinate the fender deployment plan, mooring master oversight, and pollution prevention so the davit operates inside a complete operational envelope.

What to Look For in a Supplier

When you shortlist potential vendors, weigh the practical evidence:

• Engineering against the actual fender - SWL, reach, and slew angle modelled to the specific fender size, not selected from a generic catalogue table.
• Class certificate pack as standard - DNV 2.7-1, EN 13852-1, type approval (DNV / ABS / LR / BV / RINA / ClassNK), proof-load test, and EN 10204 3.1 material certificates shipped with the unit.
• Drive expertise across hydraulic and electric - heavy STS davits demand hydraulic power pack experience; smaller deck units favour electric.
• Spares availability - hydraulic seals, swivel hooks, slew bearings, and control modules carried for the units already in service, not just the current generation.
• Commissioning and retrofit experience - documented project history on similar vessels rather than a catalogue-only supplier model.

The fender davit suppliers listed below cover hydraulic, electric, and manual configurations across the full SWL range required for STS, FPSO, and conventional berthing work. Filter by brand, country, verification, and reseller status to match the class certificate pack, drive expertise, and supply lead time your operation actually needs.
