What Is This Legislation About?
The Merchant Shipping (Wing-in-Ground Craft) Regulations 2010 (“WIG Regulations”) create a dedicated regulatory framework for wing-in-ground (WIG) craft—multimodal craft that travel using ground effect lift above water or other surfaces without constant contact. In plain terms, the Regulations ensure that WIG craft operating as Singapore ships, or operating in Singapore waters, meet specified safety standards and carry the right documentation before they proceed.
The Regulations largely “import” international technical and safety guidance by adopting the IMO’s Interim Guidelines for Wing-in-Ground (WIG) Craft (the “WIG Craft Guidelines”). However, they do not merely reference the Guidelines; they convert them into binding requirements for Singapore WIG craft and WIG craft in Singapore waters, subject to specific interpretive adjustments.
Practically, the Regulations establish a two-layer compliance regime: (1) certification of the craft’s safety status through a WIG craft safety certificate, and (2) authorisation to operate through a permit to operate WIG craft. They also provide enforcement powers (inspection, detention) and criminalise non-compliance, including proceeding to sea without the required documents.
What Are the Key Provisions?
1. Definitions and interpretive framework (Regulation 2)
The Regulations define key terms that drive compliance. Most importantly, they define “WIG craft” by its operational characteristics: it flies using ground effect above water or another surface, without constant contact, and is supported mainly by aerodynamic lift generated on wings or hull parts designed to utilise ground effect action. This definition is crucial for determining whether a craft falls within the Regulations.
The Regulations also define “WIG Craft Guidelines” by reference to specific IMO circulars (MSC/Circ.1054 and amendments MSC/Circ.1126), and they define “WIG craft safety certificate” and “permit to operate WIG craft” by reference to who may issue them (Director, authorised organisation, or foreign Flag Administration with endorsement by Singapore authorities).
2. Core safety requirements and “deeming” compliance (Regulation 3)
Regulation 3 is the heart of the regime. It provides that the Regulations apply to every Singapore WIG craft and every WIG craft in Singapore waters. This is an important jurisdictional hook: it covers both vessels flagged to Singapore and foreign WIG craft physically present/operating in Singapore waters.
Regulation 3(2) makes compliance mandatory even for WIG craft designed to carry fewer than 12 persons. This matters because some maritime safety regimes historically treat small passenger capacities differently. Here, the Regulations remove that potential carve-out by requiring compliance with the WIG Craft Guidelines.
Regulation 3(3) contains a deeming provision: if a WIG craft complies with the WIG Craft Guidelines in their entirety and has been surveyed and certified under Regulation 6(1), it is deemed to have complied with specified chapters and regulations under the Merchant Shipping (Safety Convention) Regulations. In effect, the WIG Craft Guidelines operate as a substitute compliance pathway for certain Safety Convention requirements, reducing duplication and clarifying regulatory equivalence.
Regulation 3(4) further clarifies how to read the WIG Craft Guidelines. Notably, it changes the normative language: references to “should” in the Guidelines are read as “shall”, turning recommendations into binding obligations. It also adjusts cross-references within the Guidelines (including references to “2.2 to 2.7” being read as “2.1.2 to 2.1.7”). These interpretive rules are critical for surveyors and operators because they affect whether a technical requirement is mandatory and how specific sub-paragraphs are mapped.
3. Exemptions (Regulation 4)
The Regulations provide flexibility through exemptions, but only under controlled authority. Regulation 4(1) states that, unless the Director specifies otherwise in writing, a WIG craft that complies with the Regulations is exempt from certain other Singapore merchant shipping safety regulations—specifically the Load Line, Special Limits Passenger Ships safety regulations, and Non-Convention Ships safety regulations. This is consistent with the idea that WIG craft are regulated through a tailored WIG-specific safety framework rather than through general ship safety instruments.
Regulation 4(2) allows the Director to exempt any WIG craft or description of WIG craft from all or any of the Regulations and other regulations made under the Act, on terms the Director specifies. The Director can also alter or cancel exemptions with reasonable notice. Regulation 4(3) similarly allows exemptions for persons or descriptions of persons. For practitioners, this means exemption decisions are discretionary and condition-driven; they should be documented and monitored because they can be varied or withdrawn.
4. Certification and operational authorisation (Regulations 6 and 7)
WIG craft safety certificate (Regulation 6)
A Singapore WIG craft may receive a WIG craft safety certificate after survey by the Director or an authorised organisation, provided it complies with the WIG Craft Guidelines. For foreign WIG craft, the Director may, at the request of the relevant Flag Administration, cause a survey and then issue or authorise issuance of a certificate, or endorse/authorise endorsement of a certificate issued by the Flag Administration.
Regulation 6(3) is significant: when issuing, endorsing, or authorising a certificate, the Director may impose conditions or restrictions he deems fit. This gives Singapore a mechanism to tailor compliance to operational risk, design particulars, or survey findings.
Permit to operate WIG craft (Regulation 7)
Even with a safety certificate, a craft cannot necessarily operate. Regulation 7 requires a permit to operate WIG craft for Singapore WIG craft, issued by the Director or an authorised organisation after consulting the relevant port State administration where the craft intends to operate. The permit is issued if the craft complies with specified provisions of Part A of the WIG Craft Guidelines (notably 2.1.2 to 2.1.7).
For foreign WIG craft, Regulation 7(3) allows endorsement of a permit issued by the Flag Administration if the Director or Port Master is satisfied the craft complies with the same key Part A provisions. Regulation 7(4) then imposes a hard operational rule: no foreign WIG craft shall operate in Singapore unless it has on board a permit to operate WIG craft endorsed by the Director or the Port Master. This is a practical compliance checkpoint for boarding officers and operators.
Regulation 7(2) and (5) allow conditions and restrictions to be imposed on permits and endorsements. For operators, this means the permit is not merely a formality; it may contain operational limitations (for example, routes, operating areas, or conditions tied to safety findings).
5. Enforcement: inspection, detention, and prohibition on proceeding (Regulation 8 and 9)
The Regulations provide enforcement powers to ensure compliance in real time. Regulation 8 states that WIG craft subject to the Regulations are subject, in Singapore waters, to inspection by the Director, Port Master, surveyor, or authorised officers. Inspections include verifying that the craft has on board the required documents in the form prescribed by the WIG Craft Guidelines—particularly a valid WIG craft safety certificate and a valid permit to operate (the extract truncates the remainder, but the structure indicates document verification as a core inspection element).
Where deficiencies are found, the Regulations contemplate stronger measures, including detention. Although the extract is truncated, the heading “Powers to inspect and detain” and the typical structure of maritime enforcement regimes indicate that officers may detain a craft to prevent unsafe operation until compliance is achieved.
Regulation 9 then creates a prohibition on proceeding to sea without the required documentation. In substance, it prevents a WIG craft from leaving port or proceeding on a voyage in Singapore waters unless it has a valid WIG craft safety certificate and a valid permit to operate WIG craft. This is a key risk-control provision for ship operators, charterers, and masters: even if a certificate exists but is invalid or expired, the prohibition may be triggered.
6. Offences (Regulation 10)
Regulation 10 criminalises breaches of the Regulations. While the extract does not include the offence wording, the presence of a dedicated offence regulation indicates that contraventions—such as operating without the required certificate/permit, failing to comply with conditions, or obstructing inspections—are punishable. For practitioners, the offence provision is where liability analysis will focus: who can be charged (master, operator, company), what mental element (if any) is required, and what defences may exist (for example, reliance on a valid endorsement).
How Is This Legislation Structured?
The WIG Regulations are structured as a short, self-contained subsidiary legislative instrument with an enacting formula and ten regulations:
- Regulation 1: Citation and commencement (1 April 2010).
- Regulation 2: Definitions, including the WIG Craft Guidelines and key document terms.
- Regulation 3: Requirements for WIG craft, including mandatory compliance with the WIG Craft Guidelines and deeming provisions.
- Regulation 4: Exemptions by the Director (for craft, persons, and descriptions).
- Regulation 5: Administration—mapping “Administration” and related roles in the Guidelines to Singapore’s Director and authorised organisations.
- Regulation 6: WIG craft safety certificate—issuance, endorsement, conditions.
- Regulation 7: Permit to operate WIG craft—issuance, endorsement, and the “no operation without endorsed permit” rule for foreign WIG craft.
- Regulation 8: Powers to inspect and detain.
- Regulation 9: Prohibition on proceeding to sea without valid certificate/permit.
- Regulation 10: Offence.
Who Does This Legislation Apply To?
The Regulations apply to every Singapore WIG craft and every WIG craft in Singapore waters. That means the regime is both flag-based (Singapore ships) and location-based (Singapore waters), which is typical for maritime safety regulation.
In addition, the Regulations affect multiple stakeholders: the Director, authorised organisations (survey/inspection bodies), Port Master and authorised officers (inspection and enforcement), and operators/masters of WIG craft (because they must ensure the craft carries valid certificates and permits and complies with any conditions). Foreign Flag Administrations are also indirectly involved through endorsement and survey requests, but the operational compliance obligation is enforced in Singapore through the requirement that foreign WIG craft carry an endorsed permit on board.
Why Is This Legislation Important?
The WIG Regulations are important because they provide legal certainty for a niche but safety-critical category of craft. By adopting the IMO WIG Craft Guidelines and converting “should” into “shall”, Singapore ensures that technical guidance becomes enforceable standards rather than voluntary best practice. This is especially significant for surveyors and compliance teams who must translate international guidance into domestic legal obligations.
From a practitioner’s perspective, the two-document model (safety certificate plus permit to operate) is the operational backbone. It supports a clear compliance workflow: survey and certification under Regulation 6, then operational authorisation under Regulation 7, followed by inspection and potential detention under Regulation 8. The prohibition on proceeding to sea without valid documents (Regulation 9) creates a strong deterrent against “paper compliance” or administrative delays.
Finally, the exemption provisions (Regulation 4) show legislative intent to avoid duplicative or mismatched safety regimes. By exempting compliant WIG craft from certain other ship safety regulations, the Regulations streamline compliance while preserving the ability of the Director to impose conditions or grant tailored exemptions. For operators, this can reduce regulatory friction; for regulators, it preserves discretion to manage risk.
