Modern offshore lifeboats are the last line of defence between your crew and a hostile sea, so choosing the right solution for your platform is a strategic safety decision, not just a compliance checkbox. This guide explains the lifeboats used on offshore platforms and rigs, what really matters in an emergency, and how New Marine supports operators with compliant, reliable systems.
What Is an Offshore Lifeboat?
An offshore lifeboat is a rigid, SOLAS-compliant survival craft installed on offshore platforms, drilling units, and vessels to evacuate personnel during major emergencies such as fire, explosion, or blowout. Unlike open boats or liferafts, offshore lifeboats are typically totally enclosed to protect occupants from waves, heat, smoke, and debris during and after launch, although some older or nearshore installations may still use partially enclosed designs.
On offshore oil and gas assets, lifeboats are located at dedicated embarkation stations and integrated with davits or free-fall ramps so they can launch fully loaded within a short, regulated timeframe, even under list, trim, or severe weather. For most installations, they serve as the primary survival craft for full evacuation, with helicopters or escape systems providing additional emergency escape where available.
Why Offshore Platforms Need Robust Lifeboats
Offshore platforms combine high fire load, confined spaces, and distance from shore, so evacuation systems must operate reliably under worst‑case conditions. In a major incident, your offshore platform lifeboat must protect people through safe launch, clearance from the installation, and survival until rescue.
Key risk drivers that lifeboats must address include:
High-temperature fires and explosions, requiring self-righting hulls and optional fire protection systems.
Toxic smoke and low visibility, requiring enclosed cabins with ventilation and clearly marked exits.
Severe weather, including high sea states, wind, and poor visibility, requiring stable hull forms and powerful engines.
Complex platform layouts, demanding carefully engineered davits, ramps, and access routes.
For operators, that means the "right" offshore platform lifeboat is not just the cheapest option, but the one that reliably gets your people away from the danger zone and keeps them safe until help arrives.
Main Types of Offshore Lifeboats
Totally Enclosed Offshore Lifeboats
Totally enclosed lifeboats are the workhorse solution on offshore platforms, FPSOs, and other high-risk offshore assets. In fact, most offshore lifeboats are classified as TEMPSC (Totally Enclosed Motor Propelled Survival Craft) under the IMO Life-Saving Appliances (LSA) Code. These rigid craft feature a fully covered hull, watertight doors, and integrated seating to shield occupants from weather, spray, and radiant heat.
Typical characteristics:
Fire‑retardant GRP/FRP composite hull with integrated fire‑protection systems where required
Self-righting capability, so the boat returns upright even after capsizing.
Inboard diesel engines sized to move the full load clear of the installation quickly.
Capacities commonly ranging from around 16 to 150 persons, allowing flexible coverage for different manning levels.
New Marine supplies a wide range of totally enclosed lifeboats designed and approved to current international lifeboat standards, including models optimised for offshore platform installation and use.
Free-Fall Lifeboats for Offshore Platforms
Totally enclosed free-fall lifeboats are designed for rapid evacuation from high-exposure positions, such as the stern of tankers or the outer edge of offshore platforms and FPSOs. They sit on an inclined ramp and enter the water in a single, high-speed motion.
Key advantages of free-fall offshore lifeboats include:
Extremely fast embarkation-to-water times with minimal mechanical steps.
Water entry well away from the installation, reducing exposure to fire, debris, and falling objects.
Reduced dependence on complex winch and wire systems during emergency launch.
New Marine designs free-fall lifeboats and matching launching appliances for stern or platform mounting, with ramp systems sized to the lifeboat model and hoisting loads required offshore.
Partially Enclosed and Rescue Boats
While totally enclosed and free-fall lifeboats carry most personnel during abandonment, offshore installations also carry dedicated rescue boats or fast rescue craft (FRCs) for man-overboard recovery and emergency response near the platform.
Partially enclosed lifeboats are now uncommon on modern offshore installations, but may still be found on older units or certain nearshore facilities where risk exposure is lower.
Rescue boats and FRCs support towing liferafts, personnel recovery, and incident response around the installation.
On complex assets, the complete evacuation strategy may combine enclosed lifeboats for mass abandonment with smaller craft for dedicated rescue tasks around the platform.
New Marine also manufactures rescue boats and fast rescue boats, all capable of self-righting with FRP/GRP hull and deck plus stainless steel fittings, and matches them with proper launching appliances for reliable and smooth operations.
How Offshore Lifeboats Actually Work in an Emergency
When alarms sound offshore, personnel follow muster and embarkation procedures to reach the nearest assigned lifeboat. The sequence is designed to be highly scripted and repeatable so that even under stress, the offshore lifeboat can launch safely and on time.
Typical operation includes:
Emergency activation and muster – Crews move to designated stations, where lifeboat crew or coxswains perform rapid head counts and safety checks.
Boarding and securing – Occupants strap into dedicated seats, hatches and doors are closed, and the coxswain confirms that fall preventers or safety interlocks are correctly set.
Launch – For conventional systems, davits lower the fully loaded lifeboat to the water under gravity or hydraulic control; for free-fall systems, the release triggers a skid launch down the ramp.
Clearance from the platform – Once afloat, the coxswain uses the engine to move away from the installation, avoiding fire zones, debris, and potential collapse areas.
Post-launch survival – Inside the lifeboat, occupants rely on onboard supplies, ventilation, and communications equipment until rescue units arrive or a secondary transfer is possible.
Designing and selecting lifeboats with these real-world steps in mind ensures that offshore lifeboats are more than hardware; they become a fully integrated safety system.
Oil Rig Lifeboats: What's Different on Drilling Rigs?
Drilling rigs, especially jack-ups and semi-submersibles, present a distinct risk profile, so lifeboats on oil rigs must cope with different hazards and layouts than production platforms. Frequent well operations, higher blowout risk, and dense drilling equipment mean that an oil rig lifeboat has to be positioned and specified with extra care.
On many rigs, lifeboats are mounted at the corners or outboard sides of the hull to ensure clear drop paths even when the rig is jacked up or in varying draft conditions. That requires careful engineering of davit outreach, freeboard, and clearance from the rig's legs and cantilever, especially under list or environmental load.
For operators, important oil-rig-specific lifeboat considerations include:
Ensuring enough capacity and redundancy for peak drilling manning, including contractors and service crews.
Selecting fire-protected, totally enclosed lifeboats where hydrocarbon fire and explosion risks are elevated.
Choosing launching systems that work reliably across the operating envelope of the rig, from transit to fully elevated positions.
New Marine supports rig owners with lifeboats and launching appliances sized for jack-ups, semi-subs, and other drilling units, helping ensure every oil rig lifeboat can be launched quickly and safely in a true worst-case scenario.
Key Criteria When Selecting an Offshore Platform Lifeboat
Regulatory Compliance and Capacity
Every offshore platform lifeboat must meet or exceed SOLAS and LSA Code requirements for design, equipment, and capacity. That includes providing sufficient seats for everyone on board and ensuring the lifeboats can launch within defined time limits, even under list or trim.
When assessing options, operators should check:
Certified capacity versus maximum persons on board, including contingency manning.
Approval certificates for SOLAS, flag state, and any local offshore regulations (such as MODU or national standards).
Integration with compliant davits, free-fall ramps, and secondary launching means.
Installation Environment and Layout
The same offshore lifeboat model behaves very differently depending on mounting height, sea exposure, and platform geometry. Fixed platforms, semi-subs, FPSOs, and jack-ups each present unique constraints for davit outreach, clearance paths, and safe water entry envelopes.
Critical layout considerations include:
Available mounting positions relative to living quarters and muster areas.
Drop height to water, prevailing wave climate, and potential impact loads on launch.
Interference risks from cranes, flare booms, and other topside structures.
New Marine supports project-specific selection of lifeboat and davit combinations, helping operators match hull size, capacity, and launching method to actual site conditions.
Performance, Maintenance, and Lifecycle Support
Beyond initial certification, an offshore lifeboat must remain ready for decades under harsh marine conditions. Operators should evaluate:
Engine reliability, fuel type, and ease of periodic testing.
Corrosion protection, hull materials, and fire-protective coatings.
Access to spare parts, technical documentation, and service support across the asset's life.
A well-chosen solution reduces unplanned downtime during inspections and makes it easier to perform routine drills that keep crews familiar and confident with the equipment.
