Ship designers are encouraged to consider all aspects of pilot transfer arrangements at an early stage in design. Equipment designers and manufacturers are similarly encouraged, particularly with respect to the provisions of paragraphs 2.1.2, 3.1 and 3.3.Os projetistas de navios são encorajados a considerar todos os aspectos dos arranjos para a transferência de prático em estágio inicial do projeto. Projetistas e fabricantes de equipamentos são igualmente encorajados, em particular quanto às disposições dos parágrafos 2.1.2, 3.1 e 3.3.
Who certifies, who approves, who may relax the rulesintese editorial
A.1045 hands each decision to a different authority — the manufacturer, the Administration, the Organization (via an acceptable international standard) or SOLAS itself. Questions are built on swapping them.
| Matter | Who decides / what standard | Ref |
|---|---|---|
| Pilot ladder as a whole | Certified by the manufacturer as complying with section 2 or with an international standard acceptable to the Organization (ISO 799:2004) | 2 |
| Steps made of material other than hardwood | Equivalent strength, stiffness and durability to the satisfaction of the Administration | 2.1.2.2 |
| The four lowest steps in rubber or other material | Permitted, of sufficient strength and stiffness, to the satisfaction of the Administration | 2.1.2.3 |
| Side-rope material (manila or equivalent, protected against actinic degradation) | Satisfactory to the Administration | 2.2.2 |
| Arrangements for special types of ships | May be accepted provided they are equally safe | 3.1 |
| Accommodation ladders and their suspension arrangements/attachments | To the satisfaction of the Administration (SOLAS II-1/3-9) | 3.8 |
| Waiving the 6 m unobstructed side | Only for offshore/similar ships less than 90 m where the gap is not practicable, as determined by the Administration; other appropriate measures then apply | 6 |
| Mechanical pilot hoists | Prohibited by SOLAS regulation V/23 — no authority accepts them; the Assembly further invites Governments to ensure they are not used | 4 / res. cl. 3 |
| Governments | Invited to draw the attention of all concerned; requested to ensure ladders, arrangements, use and maintenance conform to standards not inferior to the annex | res. cl. 2 & 4 |
| Ship designers / equipment makers | Encouraged to consider transfer arrangements early in design, particularly §§ 2.1.2, 3.1 and 3.3 | 1 |
Rule of thumb: construction detail → Administration; the ladder itself → manufacturer's certificate against section 2 or ISO 799:2004; the hoist prohibition → SOLAS, not the Administration.

2.1.1 The securing strong points, shackles and securing ropes should be at least as strong as the side ropes specified in section 2.2 below.2.1.1 Os pontos fortes de fixação, as manilhas e os cabos de fixação devem ser pelo menos tão resistentes quanto os cabos laterais especificados na seção 2.2 abaixo.2.1.2 The steps of the pilot ladders should comply with the following requirements:2.1.2 Os degraus das escadas de prático devem atender aos seguintes requisitos: .1 if made of hardwood, they should be made in one piece, free of knots; .1 se de madeira de lei, devem ser feitos de uma só peça, livre de nós; .2 if made of material other than hardwood, they should be of equivalent strength, stiffness and durability to the satisfaction of the Administration; .2 se de material que não seja madeira de lei, devem ter resistência, rigidez e durabilidade equivalentes, a contento da Administração; .3 the four lowest steps may be of rubber of sufficient strength and stiffness or other material to the satisfaction of the Administration; .3 os quatro degraus mais baixos podem ser de borracha de resistência e rigidez suficientes, ou de outro material a contento da Administração; .4 they should have an efficient non-slip surface; .4 devem ter uma superfície antiderrapante eficiente; .5 they should be not less than 400 mm between the side ropes, 115 mm wide and 25 mm in depth, excluding any non-slip device or grooving; .5 devem ter no mínimo 400 mm entre os cabos laterais, 115 mm de largura e 25 mm de espessura, excluído qualquer dispositivo antiderrapante ou ranhura; .6 they should be equally spaced not less than 310 mm or more than 350 mm apart; and .6 devem ser igualmente espaçados, com não menos de 310 mm nem mais de 350 mm entre si; e .7 they should be secured in such a manner that each will remain horizontal. .7 devem ser fixados de maneira que cada um permaneça na horizontal.2.1.3 No pilot ladder should have more than two replacement steps which are secured in position by a method different from that used in the original construction of the ladder, and any steps so secured should be replaced as soon as reasonably practicable by steps secured in position by the method used in the original construction of the pilot ladder. When any replacement step is secured to the side ropes of the pilot ladder by means of grooves in the sides of the step, such grooves should be in the longer sides of the step.2.1.3 Nenhuma escada de prático deve ter mais de dois degraus de reposição fixados por método diferente do usado na construção original da escada, e os degraus assim fixados devem ser substituídos tão logo razoavelmente praticável por degraus fixados pelo método da construção original. Quando um degrau de reposição for fixado aos cabos laterais por meio de ranhuras nas laterais do degrau, tais ranhuras devem estar nos lados MAIORES do degrau.2.1.4 Pilot ladders with more than five steps should have spreader steps not less than 1.8 m long provided at such intervals as will prevent the pilot ladder from twisting. The lowest spreader step should be the fifth step from the bottom of the ladder and the interval between any spreader step and the next should not exceed nine steps.2.1.4 Escadas de prático com mais de cinco degraus devem ter degraus prolongados (spreaders) com comprimento mínimo de 1,8 m, dispostos a intervalos que impeçam a escada de girar sobre si (torcer). O degrau prolongado mais baixo deve ser o quinto degrau a contar de baixo, e o intervalo entre um degrau prolongado e o seguinte não deve exceder nove degraus.2.1.5 When a retrieval line is considered necessary to ensure the safe rigging of a pilot ladder, the line should be fastened at or above the last spreader step and should lead forward. The retrieval line should not hinder the pilot nor obstruct the safe approach of the pilot boat.2.1.5 Quando uma linha de recuperação (retrieval line) for considerada necessária para garantir a armação segura da escada, a linha deve ser fixada no último degrau prolongado ou acima dele e deve ser guiada para vante. A linha de recuperação não deve atrapalhar o prático nem obstruir a aproximação segura da lancha de prático.2.1.6 A permanent marking should be provided at regular intervals (e.g. 1 m) throughout the length of the ladder consistent with ladder design, use and maintenance in order to facilitate the rigging of the ladder to the required height.2.1.6 Deve haver marcação permanente a intervalos regulares (p. ex., 1 m) ao longo de todo o comprimento da escada, compatível com o projeto, o uso e a manutenção, para facilitar a armação da escada na altura requerida.
Pegadinha
Two favourites of examiners: only the FOUR lowest steps may be rubber, and the lowest spreader is the 5th step from the bottom — swap either number and the statement is false. The retrieval line leads forward, never aft.
- Side ropes: two uncovered ropes ≥18 mm diameter each side, continuous, no joints; breaking strength ≥24 kN per side rope; midpoint half-length on a thimble (≥2 passes). [2.2.1]
- Material: manila or equivalent; protected against actinic degradation (UV). [2.2.2]
- Pairs secured together above and below every step by a mechanical clamp or seizing with chocks/widgets, keeping each step level; seizing is preferred. [2.2.3]

2.2.1 The side ropes of the pilot ladder should consist of two uncovered ropes not less than 18 mm in diameter on each side and should be continuous, with no joints and have a breaking strength of at least 24 Kilo Newtons per side rope. The two side ropes should each consist of one continuous length of rope, the midpoint half-length being located on a thimble large enough to accommodate at least two passes of side rope.2.2.1 Os cabos laterais da escada de prático devem consistir em dois cabos sem revestimento, com diâmetro mínimo de 18 mm em cada bordo, contínuos, sem emendas, e com carga de ruptura de pelo menos 24 quilonewtons por cabo lateral. Cada um dos dois cabos laterais deve consistir num único lanço contínuo de cabo, com o ponto médio (meia-extensão) apoiado num sapatilho grande o bastante para acomodar pelo menos duas passadas do cabo lateral.2.2.2 Side ropes should be made of manila or other material of equivalent strength, durability, elongation characteristics and grip which has been protected against actinic degradation and is satisfactory to the Administration.2.2.2 Os cabos laterais devem ser de manilha ou de outro material de resistência, durabilidade, características de alongamento e pega equivalentes, protegido contra a degradação actínica (UV) e a contento da Administração.2.2.3 Each pair of side ropes should be secured together both above and below each step with a mechanical clamping device properly designed for this purpose, or seizing method with step fixtures (chocks or widgets), which holds each step level when the ladder is hanging freely. The preferred method is seizing. [Footnote 2: Refer to ISO 799:2004, Ships and marine technology — Pilot ladders, part 4.3a and part 3, paragraph 3.2.1.]2.2.3 Cada par de cabos laterais deve ser fixado em conjunto, acima E abaixo de cada degrau, por dispositivo mecânico de aperto projetado para essa finalidade, ou por método de falcaça com peças de fixação do degrau (calços ou acessórios), que mantenha cada degrau nivelado quando a escada estiver pendendo livremente. O método preferido é a falcaça (seizing). [Nota 2: Consultar a ISO 799:2004, Ships and marine technology — Pilot ladders, parte 4.3a e parte 3, parágrafo 3.2.1.]
Pegadinha
It is two ropes on EACH side (four in total), continuous and unjointed — and between the fastening methods, seizing is PREFERRED over the mechanical clamp, not the other way round.

3.1 Arrangements which may be more suitable for special types of ships may be accepted, provided that they are equally safe.3.1 Arranjos que sejam mais adequados a tipos especiais de navios podem ser aceitos, desde que igualmente seguros.3.2 The length of the accommodation ladder should be sufficient to ensure that its angle of slope does not exceed 45°. In ships with large draft ranges, several pilot ladder hanging positions may be provided, resulting in lesser angles of slope. The accommodation ladder should be at least 600 mm in width.3.2 O comprimento da escada de portaló deve ser suficiente para assegurar que seu ângulo de inclinação não exceda 45°. Em navios com grandes variações de calado, podem ser previstas várias posições de armação da escada de prático, resultando em ângulos de inclinação menores. A escada de portaló deve ter largura mínima de 600 mm.3.3 The lower platform of the accommodation ladder should be in a horizontal position and secured to the ship's side when in use. The lower platform should be a minimum of 5 m above sea level.3.3 A plataforma inferior da escada de portaló deve ficar na posição horizontal e presa ao costado do navio quando em uso. A plataforma inferior deve ficar no mínimo 5 m acima do nível do mar.3.4 Intermediate platforms, if fitted, should be self-levelling. Treads and steps of the accommodation ladder should be so designed that an adequate and safe foothold is given at the operative angles.3.4 As plataformas intermediárias, se existirem, devem ser autonivelantes. Os pisos e degraus da escada de portaló devem ser projetados de modo a proporcionar apoio adequado e seguro para os pés nos ângulos de operação.3.5 The ladder and platform should be equipped on both sides with stanchions and rigid handrails, but if handropes are used they should be tight and properly secured. The vertical space between the handrail or handrope and the stringers of the ladder should be securely fenced.3.5 A escada e a plataforma devem ser dotadas, em ambos os lados, de balaústres e corrimãos rígidos; se forem usados cabos-corrimão (handropes), estes devem estar tesos e devidamente fixados. O vão vertical entre o corrimão (ou cabo-corrimão) e os banzos da escada deve ser guarnecido com proteção segura.3.6 The pilot ladder should be rigged immediately adjacent to the lower platform of the accommodation ladder and the upper end should extend at least 2 m above the lower platform. The horizontal distance between the pilot ladder and the lower platform should be between 0.1 and 0.2 m.3.6 A escada de prático deve ser armada imediatamente adjacente à plataforma inferior da escada de portaló, e sua extremidade superior deve prolongar-se pelo menos 2 m acima da plataforma inferior. A distância horizontal entre a escada de prático e a plataforma inferior deve ficar entre 0,1 e 0,2 m.3.7 If a trapdoor is fitted in the lower platform to allow access from and to the pilot ladder, the aperture should not be less than 750 mm x 750 mm. The trapdoor should open upwards and be secured either flat on the embarkation platform or against the rails at the aft end or outboard side of the platform and should not form part of the handholds. In this case the after part of the lower platform should also be fenced as specified in paragraph 3.5 above, and the pilot ladder should extend above the lower platform to the height of the handrail and remain in alignment with and against the ship's side.3.7 Se houver alçapão na plataforma inferior para dar acesso de e para a escada de prático, a abertura não deve ser menor que 750 mm x 750 mm. O alçapão deve abrir PARA CIMA e ficar preso ou rebatido sobre a plataforma de embarque ou contra a balaustrada na extremidade de ré ou no lado de fora da plataforma, e não deve fazer parte dos pega-mãos. Nesse caso, a parte de ré da plataforma inferior também deve ser guarnecida como especificado no parágrafo 3.5 acima, e a escada de prático deve prolongar-se acima da plataforma inferior até a altura do corrimão, mantendo-se alinhada com o costado e apoiada contra ele.3.8 Accommodation ladders, together with any suspension arrangements or attachments fitted and intended for use in accordance with this recommendation, should be to the satisfaction of the Administration. [Footnote 3: Refer to SOLAS regulation II-1/3-9 concerning accommodation ladders.]3.8 As escadas de portaló, junto com quaisquer arranjos de suspensão ou acessórios instalados e destinados ao uso conforme esta recomendação, devem estar a contento da Administração.

Strongest norm in the resolution: mechanical pilot hoists are PROHIBITED by SOLAS V/23 — not "discouraged", not "subject to Administration approval". Any softer wording is wrong.
- Ensure safe, convenient, unobstructed passage between the head of the pilot/accommodation ladder and the deck, via a platform guarded by handrails.
- Gateway in rails/bulwark: handholds each side 0.7–0.8 m apart, ≥32 mm diameter, extending ≥1.2 m above the deck to which fitted. [.1]
- Bulwark ladder: two separate handhold stanchions each side 0.7–0.8 m apart, ≥32 mm diameter, extending ≥1.2 m above the bulwark top; ladder securely attached (anti-overturn); stanchions/handrails not attached to the bulwark ladder. [.2]
- Each gateway handhold and each bulwark-ladder stanchion: rigidly secured to the ship's structure at or near its base and also at a higher point. [.1–.2]

Means should be provided to ensure safe, convenient and unobstructed passage for any person embarking on, or disembarking from, the ship between the head of the pilot ladder, or of any accommodation ladder, and the ship's deck; such access should be gained directly by a platform securely guarded by handrails. Where such passage is by means of:Devem ser providos meios que assegurem passagem segura, conveniente e desobstruída, a qualquer pessoa que embarque ou desembarque do navio, entre o topo da escada de prático (ou de qualquer escada de portaló) e o convés do navio; esse acesso deve dar-se diretamente por uma plataforma guarnecida com corrimãos seguros.

The A.1108(29) amendment is itself examinable: for a gateway the handhold now extends ≥1.2 m above the DECK to which it is fitted (the original said "above the top of the bulwarks"). And the bulwark-ladder stanchions must NOT be attached to the bulwark ladder.
Amended by Resolution A.1108(29) (adopted 2 Dec 2015): for a gateway, the handhold now extends ≥1.2 m above the deck to which it is fitted (originally "above the top of the bulwarks"); the bulwark-ladder item was restructured to require two separate handhold stanchions.
- If rubbing bands/constructional features could block the pilot boat, cut them back to give ≥6 m of unobstructed ship's side.
- Exception: specialized offshore / other similar ships under 90 m where a 6 m gap is impracticable (as determined by the Administration) — instead take other appropriate measures for safe embark/disembark.

Where rubbing bands or other constructional features might prevent the safe approach of a pilot boat, these should be cut back to provide at least 6 metres of unobstructed ship's side. Specialized offshore ships less than 90 m or other similar ships less than 90 m for which a 6 m gap in the rubbing bands would not be practicable, as determined by the Administration, do not have to comply with this requirement. In this case, other appropriate measures should be taken to ensure that persons are able to embark and disembark safely.Onde verdugos (cintas de defensa) ou outras características construtivas possam impedir a aproximação segura da lancha de prático, eles devem ser recortados de modo a prover pelo menos 6 metros de costado desobstruído. Navios offshore especializados com menos de 90 m, ou outros navios semelhantes com menos de 90 m para os quais um vão de 6 m nos verdugos não seja praticável, conforme determinado pela Administração, ficam dispensados deste requisito. Nesse caso, outras medidas apropriadas devem ser adotadas para assegurar que as pessoas possam embarcar e desembarcar em segurança.

The two means of access and the hoist/reel distinction are classic trick questions.
| Item | What it is / rule | Key contrast |
|---|---|---|
| Gateway (in rails/bulwark) | Opening with handholds each side; handhold extends ≥1.2 m above the deck to which fitted | Handhold height is measured above the deck (changed by A.1108) |
| Bulwark ladder | Needs two separate handhold stanchions each side; stanchion extends ≥1.2 m above the bulwark top | Height measured above the bulwark top, not the deck; stanchions NOT attached to the bulwark ladder |
| Mechanical pilot hoist | PROHIBITED by SOLAS V/23 (and clause 3 of the resolution) | Never allowed |
| Pilot ladder winch reel | Allowed (section 7), but must not support the ladder in use — secure to an independent strong point | A reel is NOT a hoist; the reel only stows/deploys the ladder |
A.1108(29) amended §5: the gateway handhold now extends ≥1.2 m above the deck to which it is fitted (was "above the top of the bulwarks").

Pegadinha
The reel is a STOWAGE device: it must never be relied upon to support the ladder in use — the ladder is secured to a strong point independent of the reel. Statements making the reel load-bearing are false.
- All reels: means to prevent accidental operation from mechanical failure or human error. [7.5.1]
- Reels may be manual or powered by electrical, hydraulic or pneumatic means. [7.5.2]
- Manual reels: a brake (or suitable arrangement) to control lowering and lock the reel in position. [7.5.3]
- Powered reels: safety devices that cut off power and lock the reel [7.5.4];
clearly marked levers/handles lockable in neutral [7.5.5];
plus a mechanical device or locking pin [7.5.6].

Winch reels: the two installations comparedsintese editorial
Section 7 fits the reel either on the upper (main) deck or inside a ship's side opening, and gives each its own list. Read the two columns against each other.
| Requirement | Reel on the upper (main) deck | Reel inside a ship's side opening | Ref |
|---|---|---|---|
| Where it is normally fitted | Upper (main) deck — the resolution warns this may result in very long pilot ladders | Side opening — side doors, gangway locations or bunkering points | 7.2.1 |
| Unobstructed clear area at the access position | 915 mm in width (longitudinal), 915 mm in depth from the side plating inwards, 2,200 mm in height from the access deck | Same three figures: minimum length 915 mm, width 915 mm, vertical height 2,200 mm | 7.1.3 / 7.2.3.2 |
| How the ladder must hang | From a place on the deck where it is suspended vertically, in a straight line, to a point adjacent to the side opening or to the lower platform | Not applicable; but where a section of ladder must lie horizontally on the deck to keep the access clear, that section may be covered with a rigid platform for ≥915 mm measured horizontally from the ship's side inwards | 7.2.2.1 / 7.2.3.3 |
| Platform at the access point | Extends outboard ≥750 mm, longitudinal length ≥750 mm, securely guarded by handrails | Not prescribed — access is the deck inside the opening | 7.2.2.3 |
| Securing the ladder and manropes to the ship's side | At a point 1,500 mm above the platform access point to the side opening or above the lower platform of the accommodation ladder | — | 7.2.2.4 |
| Securing the ladder at deck level | ≥915 mm from the ship's side, measured horizontally inwards | At deck level inside the side opening | 7.4.3 |
| If a combination arrangement is provided | Accommodation ladder secured to the ship's side at or close to the lower platform, so that it rests firmly against the ship's side | — | 7.2.2.5 |
| Common to both | The reel must not be relied upon to support the ladder in use; the ladder is secured to a strong point independent of the reel | Identical — 7.4.1 and 7.4.2 apply wherever the reel sits | 7.4.1–7.4.2 |
| Handrails / handgrips | Per section 5, spaced 0.7–0.8 m apart | Per section 5, same spacing — the only exception is the outboard platform of 7.2.2.3 | 7.3 |
Both installations share section 7.1.3 (clear access), 7.4 (independent securing) and 7.5 (mechanical securing of the reel). What genuinely differs is the outboard platform and the 1,500 mm securing height, which belong to the upper-deck reel only.
Don't confuse — manually operated x powered winch reelsnao confundir
Section 7.5 gives each drive type its own safety fittings. Swapping them is the standard trap.
| Item | Manually operated reel | Powered reel (electrical / hydraulic / pneumatic) |
|---|---|---|
| What controls the lowering | A brake or other suitable arrangement to control the lowering and to lock the reel in position once the ladder is lowered (7.5.3) | Safety devices capable of cutting off the power supply to the reel, thereby locking it in position (7.5.4) |
| Control levers or handles | Not prescribed | Clearly marked and lockable in a neutral position (7.5.5) |
| Additional mechanical lock | Not prescribed | A mechanical device or locking pin should also be used (7.5.6) |
| Guard against accidental operation | Required — 7.5.1 applies to all reels | Required — same clause, same wording |
7.5.2: reels may be manually operated or powered — the resolution does not prefer either. Note also that the trigger for the extra fittings is the drive, not where the reel is installed.
