Vessel helideck and winching requirements
Before any commercial vessel transfer is planned as flyable, one question has to be answered honestly: what can this specific vessel actually receive? There are three outcomes — a certified helideck permitting a landing, a designated area permitting winching only, or no suitable arrangement at all. That answer comes from the vessel's own documentation and the performing operator's assessment, and it is the single most common reason a requested transfer does not proceed. This page explains what is normally examined; it is orientation for planning, not a certification standard or operational guidance.

- Coverage
- Worldwide, subject to independent operator availability on your route and dates.
- Who it's for
- Ship managers and technical departments, masters and chief officers, safety and marine assurance teams, charterers and project managers assessing whether a vessel can receive a helicopter.
- How it works
- Send route, dates, passengers and luggage — offers from suitable independent operators are returned for comparison.
- Who operates the flight
- An independent third-party operator. SkyMatch coordinates and does not operate aircraft; operational responsibility remains with the operator.
What a commercial vessel needs before a helicopter transfer: certified helideck versus winching area, obstruction clearance, wind over deck, crew readiness, documentation and who approves the operation.
Certified helideck: a purpose-built, documented and marked landing area with defined dimensions, load-bearing capacity, markings, lighting, firefighting provision and obstacle-protected sectors. Common on offshore, drilling, research and some specialised vessels; uncommon on ordinary merchant ships.
Winching (hoist) area: a designated clear area with documented obstruction clearance used for hoist operations only. Many merchant vessels have this rather than a helideck, and the aircraft never touches the ship.
Neither: a great many vessels are simply not arranged for helicopter operations. That is a normal outcome and the plan should shift to a port call or a launch.
Obstructions: masts, cranes, antennas, rigging, cargo, containers and hatch equipment govern what is possible more often than deck size does, and they change with the cargo loaded.
Wind over deck: the vessel's heading and speed relative to the wind materially affect the operation, which is why transfers to a vessel underway are frequently preferable to a vessel at anchor.
Motion: pitch, roll and heave limits apply and are assessed against the aircraft and the operation type. Large vessels are steadier, but that does not make them automatically suitable.
Crew readiness: deck party, firefighting readiness, communications with the aircraft, and briefing of the transferring personnel are part of the operation, not an afterthought.
Documentation: the vessel's helicopter operations documentation, the operator's risk assessment, owner authorisation and any charterer, terminal or flag requirement are all reviewed before the mission is treated as viable.
Nothing on this page approves an operation. The performing operator and the master make that judgement for the specific vessel, condition and day.

Frequently Asked Questions
Start with the vessel's own documentation — whether a certified helideck or a designated winching area exists, and under what conditions. Then a performing operator assesses it for the specific operation. Send the vessel details and we will get that assessment underway with suitable licensed operators.
No. Deck size is rarely the deciding factor; certification, load-bearing, markings, obstruction-protected sectors, firefighting provision and documentation are. A large ship without a certified helideck is a winching case at best.
No — it is a more demanding operation with tighter weather and obstruction limits, one person at a time, and firm restrictions on what can be carried. It exists because most vessels have no helideck, not because it is simpler.
No. Weather, vessel motion, cargo status, crew readiness, daylight and the operator's own assessment on the day all still apply, and both the master and the helicopter commander can decline.
The master of the vessel and the helicopter commander, jointly and independently. Either can decline. Vessel motion, wind over the deck, obstructions, cargo status, deck condition, crew readiness and the aircraft's own limits all feed that decision, and it is frequently made on the day rather than in advance.
Typically the shipowner or manager's authorisation, the master's acceptance, the operator's own risk assessment for that vessel and operation, port or coastal-state permission where the transfer occurs inside territorial waters, and any flag-state or charterer requirement. Where the vessel is under a terminal or charterer's control, their marine assurance function is usually involved too.
More than almost any other charter type. Wind strength and direction relative to the vessel's heading, sea state and resulting vessel motion, visibility, cloud base and — for many operations — daylight all constrain the window. Build alternative dates or a fallback mode into the plan rather than assuming a single slot will hold.
Weights and dimensions must be declared up front and are strictly controlled, particularly for winching, where each item is handled individually. Dangerous goods need classification and may be refused outright. Send the manifest with the request — payload commonly decides the aircraft category and sometimes decides whether the transfer is viable.
Neither. SkyMatch is an independent helicopter sourcing, brokerage and coordination platform. Flights are performed by independent licensed operators. The master, the shipowner or manager, the port and coastal authorities and the performing operator confirm aircraft, approach, winching or deck landing, timing, permits and whether the transfer happens at all.
