Products Description

Lifeboat Recovery Strop is a dedicated lifting and recovery auxiliary device for marine life-saving systems. It is independently equipped on lifeboat/rescue boat launching and recovery appliances, applicable to emergency recovery operations when the conventional fall lifting system fails or encounters extreme sea conditions.

The product is made with high-performance UHMWPE rope, fitted with anti-wear metal thimbles & shackles at one end and and high-strength lifting ring on the other end. It provides stable lifting tension and balanced stress transmission during the whole recovery process of lifeboats. With a standardized safety factor of 6:1 and compliance with ISO 2307:2019, it can adapt to long-term marine environments of high salt spray, strong ultraviolet radiation, oil pollution and high humidity. It is universally compatible with most shipboard lifeboat davit systems and rescue boat equipment, and is a standard safety configuration for modern marine lifesaving systems.

Product feature

1. Superior Load Performance & High Safety Factor

Adopts high-strength UHMWPE rope, with strength 15 times that of steel wire of the same specification. Strictly follows 6:1 safety factor design, passes safe working load pressure test with DNV certificate, effectively avoiding fracture and failure during high-load recovery operations.

2.Full Marine Environment Resistance

Integrated anti-aging, anti-ultraviolet, oil-proof and waterproof treatment. Resists salt spray corrosion, seawater erosion and mildew rot, maintains stable mechanical performance after long-term exposure to outdoor marine environment, no brittle failure or strength attenuation.

3. Lightweight & Easy Operation

High strength-to-weight ratio design, lighter than traditional steel wire strops, easy for crew to manually install, connect and retract. No complex tools required, realizing rapid docking and emergency recovery in extreme sea conditions.

4.High Visibility Safety Design

Adopts international standard high-visibility yellow color main body, ensuring clear visual identification in night, fog and low-light marine environments, improving operation safety.

Application

Lifeboat Recovery Strop is widely used in all scenarios requiring lifeboat and rescue boat launching and recovery in marine and offshore industries.

INSPECTION CERTIFICATE ISSUED BY DNV TESTED ACCORDING TO AS PER ISO 2307:2019

FAQ

Q: What is the core function of the lifeboat recovery strop, and is it a mandatory ship fitting?

A: The core function is to assist the safe recovery of lifeboats/rescue boats under foul weather and conventional lifting system failure conditions. It is a mandatory safety fitting required by SOLAS regulations for all ocean-going vessels and offshore platforms, and must be equipped and pass inspection to meet ship navigation certification requirements.

Q: What is the service life of the strop, and how to judge replacement demand?

A: The standard service life is 5 years under normal marine use. It needs to be replaced immediately if there are rope strand wear, fracture, aging hardening, hardware corrosion and deformation, or strength attenuation detected during daily inspection, even within the warranty period.

Q: Can the product adapt to extreme low temperature and high temperature marine environments?

A: Yes. The product working temperature range is -30℃ to +80℃, adapting to polar low-temperature navigation and tropical high-temperature marine environments. The material will not undergo brittle failure or strength decline in extreme temperature environments.

Q: Is the product compatible with all types of lifeboat davit systems?

A: Standard specifications are universally compatible with most mainstream ship lifeboat davit and rescue boat lifting systems. For special model equipment, we can provide customized size and interface matching services to ensure perfect installation and use.

Q: What qualification documents will be provided for ship inspection?

A: We will provide complete DNV inspection certificate, factory test report, with series numbers that match with the series number on the name plate attached to the product.

Q: How to maintain the strop daily to extend service life?

A: After use, clean the strop surface of seawater, oil stains and sundries, dry and store it in a dry and ventilated cabin, avoid long-term direct sunlight and heavy extrusion. Regularly check rope body wear and hardware corrosion status, and avoid overloaded use.

Q: Is overloaded use allowed in emergency rescue scenarios?

A: Overloaded use is strictly prohibited. The product is designed with a 6-fold safety factor, and the safe working load is the maximum allowable load for long-term use. Overload will cause irreversible strength attenuation and hidden fracture dangers, seriously endangering rescue safety.
